Description

  The present invention relates to a so-called terminal-to-terminal pairing method in which a call terminal such as a mobile phone and an information processing terminal such as a personal computer (PC) are associated with each other and cooperate with each other. The present invention relates to an acceleration sensor-based pairing method, system, and apparatus, and an acceleration sensor-based pairing program that can be reliably paired as described above and can be realized at low cost.

  Patent Document 1 describes a so-called terminal pairing method in which a user of a call terminal such as a telephone that performs a voice call associates the call terminal with an information processing terminal such as a PC and cooperates with each other. . In the method described in Patent Document 1, by doing so, it is possible to simultaneously use a voice call and data sharing for viewing and collaboratively editing document data including text and images with other users in real time. Supports communication between users.

  In the method described in Patent Document 1, first, both users who are making a voice call using a telephone terminal manually input (manually input) terminal identification information such as the telephone number of their telephone terminal into the information processing terminal. Thus, the call terminal and the information processing terminal are paired on the server side, and two pairs are created. Next, data sharing is automatically started between the information processing terminal of one pair and the information processing terminal of the other pair.

  Patent Document 2 describes a user authentication method in a remote controller including an acceleration sensor (sometimes referred to as an accelerometer or a motion sensor).

  In the method described in Patent Document 2, when the user moves the remote controller, the remote controller detects acceleration when the remote controller is moved, and calculates a password having a combination of the direction and magnitude of the acceleration as elements. To do. Then, the remote controller performs user authentication using the calculated password. A user operates a remote controller whose user authentication has been completed, thereby using a radio such as infrared rays to provide a nearby television receiver (hereinafter referred to as a TV terminal) TV terminal or hard disk drive recorder (hereinafter referred to as an HDD recorder terminal). Can be remotely controlled (paragraph 0027). By including authenticated user information in the remote control control signal, it is possible to execute a process specific to the user on a television terminal, HDD recorder terminal, or the like (paragraph 0029). For example, in a television terminal, the channel or program to be displayed can be changed for each user who operates the remote controller. Further, in the HDD recorder terminal, only the content recorded in the past by the user operating the remote controller can be set as a reproduction target (paragraph 0030).

JP 2005-012380 A JP 2007-179169 (paragraphs 0027-0030)

  However, the method described in Patent Document 1 places a heavy burden on the user during the pairing operation, and thus cannot be easily paired. The reason is that the method described in Patent Document 1 forces a user during a voice call to manually input the telephone number of his / her call terminal into the information processing terminal during the pairing operation. It is. Manual entry of a telephone number is a laborious operation. Further, there are cases where the user remembers the phone number of another person but does not remember his own phone number. Some call terminals have a function to display their own phone number by performing a specific operation, but since many models cannot use functions other than volume adjustment during a call, the user operates the call terminal. You can't even know your phone number. Therefore, a user who does not remember his / her telephone number needs to find out his / her telephone number using other means.

  Further, in the method described in Patent Document 1, a pair different from the user's intention may be assembled, and the pairing reliability is poor. The reason is that in the method described in Patent Document 1, if the user manually inputs an incorrect telephone number into the information processing terminal without noticing the error, the information processing terminal and the other person's call terminal are This is because they are unintentionally paired.

  As an example, consider a scene in which user A and user B, and user C and user D are talking. For example, if the user A manually inputs an incorrect telephone number and happens to be the telephone number of the user C, the information processing terminal of the user A and the telephone terminal of the user C are paired. . As a result, data sharing is started between the information processing terminal of user A and the information processing terminal of user D.

  The method described in Patent Document 2 is merely a user authentication method, and can only specify a user who operates a remote controller from a group of users having a plurality of candidates. For this reason, it is impossible to eliminate the possibility of an erroneous operation in which the user remotely controls a terminal different from the user's intention using the remote controller. In order to remotely control a terminal using a remote controller, it is necessary to associate the remote controller and the terminal in some form, but this association is conceptually equivalent to pairing.

  As described in paragraph 0027 of Patent Document 2, a remote controller and a terminal such as a television terminal or an HDD recorder terminal have a one-to-many relationship. As a result, for example, the user may operate the HDD recorder terminal in an attempt to remotely control the TV recorder terminal, but the television terminal may be remotely controlled.

  Note that paragraphs 0205 to 0206 of Patent Document 2 describe a method of performing user authentication by vibrating a pointing device such as a mouse of an information processing terminal. However, since this is a user authentication method within the information processing terminal, it cannot be used for pairing the call terminal and the information processing terminal.

  Therefore, the present invention uses an acceleration sensor that does not place a heavy burden on the user during the pairing operation, and can easily and reliably prevent pairing that is different from the user's intention. An object of the present invention is to provide a pairing method, system, apparatus, and acceleration sensor-based pairing program.

As shown in FIG. 1, the pair management device 100, the call terminal A10, the call terminal B11, the information processing terminal A20, and the information processing terminal B21 are mutually connected via a communication network such as the Internet or a mobile phone network. It is connected. In this embodiment, a case where there are two call terminals and two information processing terminals is shown, but any number (for example, three or more) may be used. In this embodiment, a call terminal and an information processing terminal are used as terminals, but a terminal that does not have a call function (for example, a PDA (Personal Digital Assistant) or the like) may be used.

  FIG. 2 is a functional block diagram showing a functional configuration of the acceleration sensor-based pairing method. FIG. 3 is an explanatory diagram showing an example of a data structure in the embodiment of the present invention. This will be described with reference to these figures.

  As shown in FIG. 2, the pair management apparatus 100 includes a trajectory comparison unit 101, a pair storage unit 102, and a trajectory storage unit 103. Specifically, the pair management apparatus 100 is realized by an information processing apparatus such as a personal computer that operates according to a program.

  The trajectory comparison unit 101 is specifically realized by a CPU of an information processing apparatus that operates according to a program. The trajectory comparison means 101 receives the trajectory 220 from the call terminal and the trajectory 230 from the information processing terminal, generates the trajectory 210 based on the two trajectory information, and based on the generated trajectory 210, the information on the call terminal and information It is determined whether or not to form a pair with the processing terminal, and when it is determined to form a pair, a function for generating the pair 200 is provided.

  Specifically, the pair storage unit 102 is realized by a storage device such as a magnetic disk device or an optical disk device. The pair storage unit 102 stores a plurality of pairs 200. There are the same number of pairs 200 as the established pairs. The pair 200 is information corresponding to a pair of “terminal number” and “linked PC IP address” shown in FIG. 2 and FIG.

  Specifically, the trajectory storage unit 103 is realized by a storage device such as a magnetic disk device or an optical disk device. The trajectory storage unit 103 stores a plurality of trajectories 210. The trajectory storage means 103 collectively manages a series of trajectories 210 for each vibration operation between the call terminal and the input means by the user. For example, when two users perform vibration operations separately, two sets of a series of trajectories 210 are generated.

  The trajectory 210 includes a time 211, a call terminal X coordinate 212, a call terminal Y coordinate 213, an information processing terminal X coordinate 214, and an information processing terminal Y coordinate 215.

  Time 211 is the time when the call terminal or the information processing terminal collects the trajectory information. However, the time 211 is not the time on the clock mounted on the call terminal or the information processing terminal, but the time on the clock mounted on the pair management apparatus 100.

  The call terminal X coordinate 212 is the value of the X coordinate of the position of the call terminal on the XY plane collected by the call terminal at time 211.

  The call terminal Y coordinate 213 is the value of the Y coordinate of the position of the call terminal on the XY plane collected by the call terminal at time 211.

  The information processing terminal X coordinate 214 is the value of the X coordinate of the position of the information processing terminal on the XY plane collected by the information processing terminal at time 211.

  The information processing terminal Y coordinate 215 is the value of the Y coordinate of the position of the information processing terminal on the XY plane collected by the information processing terminal at time 211.

  Specifically, the call terminal A10 is realized by a mobile phone, a smart phone, a fixed phone, a street multimedia terminal, an in-vehicle terminal, a game machine, or other similar device having a function of exchanging information with the outside, which operates according to a program. The Since the configuration of the call terminal B11 is the same as that of the call terminal A10, the description is omitted.

  Call terminal A10 includes acceleration detection means A111, acceleration / speed conversion means A113, trajectory calculation means A114, vibration monitoring means A115, time correction means A116, and trajectory storage means A117.

  The acceleration detection means A111 is realized by an acceleration sensor that can detect acceleration information when the call terminal A10 physically moves along a time series. The acceleration information detected by the acceleration detecting means A111 is obtained by taking the horizontal direction of the call terminal A10 as the X axis and the vertical direction of the call terminal A10 on a horizontal plane with respect to the ground, that is, a plane perpendicular to the direction where the gravity of the earth is applied. It consists of the direction and magnitude of acceleration on the XY plane as the Y axis.

  Specifically, the acceleration / speed conversion means A113 is realized by a CPU of an information processing apparatus that operates according to a program. The acceleration / speed conversion means A113 has a function of converting acceleration information along the time series detected by the acceleration detection means A111 into speed information along the time series. This speed information is obtained from the X-axis in which the horizontal direction of the call terminal A10 is the X axis and the vertical direction of the call terminal A10 is the Y axis on a plane that is horizontal to the ground, that is, a plane perpendicular to the direction in which the earth's gravity is applied. It is composed of the speed direction and magnitude on the Y plane. This conversion can be realized by integrating acceleration information along a time series.

  The trajectory calculation means A114 is specifically realized by a CPU of an information processing apparatus that operates according to a program. The trajectory calculation unit A114 has a function of converting the speed information along the time series calculated by the acceleration / speed conversion unit A113 into a trajectory along the time series. This conversion can be realized by integrating velocity information along a time series.

  Specifically, the vibration monitoring unit A115 is realized by a CPU of an information processing apparatus that operates according to a program. The vibration monitoring unit A115 monitors the trajectory calculated by the trajectory calculating unit A114, and the acceleration detecting unit A111 starts to be moved by the user's hand (vibration start), and the user's hand stops after the vibration ends ( (Vibration end) is detected. The vibration monitoring unit A115 has a function of calculating in which direction on the XY plane the acceleration detection unit A111 starts moving (initial inclination) when the vibration start is detected.

  Specifically, the time correction unit A116 is realized by a CPU of an information processing apparatus that operates according to a program. The time correction means A116 calculates the time difference between the clocks by exchanging the time information of the clock installed in the pair management device 100 and the time information of the clock installed in the call terminal A10, and is originally installed in the call terminal A10. A function of converting the time 221 stored as the time on the clock to be converted into the time on the clock of the pair management apparatus 100 is provided.

  Specifically, the trajectory storage unit A117 is realized by a storage device such as a magnetic disk device or an optical disk device. The trajectory storage unit A117 stores a plurality of trajectories 220 and an initial inclination 224. The trajectory storage unit A117 uses the trajectory 220 as a trajectory 220 on the acceleration detection unit A111 calculated by the trajectory calculation unit A114 on the horizontal plane, that is, the plane perpendicular to the direction in which the gravity of the earth is applied. Stores a position in time series on the XY plane with the direction as the X axis and the vertical direction of the call terminal A10 as the Y axis.

  The locus 220 includes a time 221, an X coordinate 222, and a Y coordinate 223 as shown in FIG. 3.

  Time 221 is the time when the acceleration detection means A111 detects the acceleration information. The time 221 is initially stored as the time on the clock mounted on the call terminal A10, but later converted to the time on the clock mounted on the pair management apparatus 100 and is overwritten and stored.

  The X coordinate 222 is the value of the X coordinate of the position of the acceleration detection means A111 on the XY plane at the time 221.

  The Y coordinate 223 is the value of the Y coordinate of the position of the acceleration detection means A111 on the XY plane at the time 221.

  The initial inclination 224 is calculated when the vibration monitoring unit A115 detects the start of vibration, and indicates in which direction on the XY plane the acceleration detection unit A111 starts to move. Specifically, the initial inclination 224 corresponds to the inclination of a straight line when the direction in which the acceleration detecting unit A111 starts to move is expressed by a straight line passing through the origin of the XY plane.

  Specifically, the information processing terminal A20 is a personal computer (PC), a portable computer (PDA), a mobile phone, a smartphone, a fixed phone, a street multimedia terminal, an in-vehicle terminal, a TV with a network connection function, and a network connection function. It is realized by a set-top box, a game machine, or other similar devices having a function of exchanging information with the outside. Since the configuration of the information processing terminal B21 is the same as that of the information processing terminal A20, the description thereof is omitted.

  As shown in FIG. 2, the information processing terminal A20 includes an input unit A123, a trajectory calculation unit A124, a vibration monitoring unit A125, a time correction unit A126, and a trajectory storage unit A127.

  Specifically, the input means A123 has a touch pad provided in a mouse, a notebook PC, etc., a touch panel display device provided in a PDA, a smartphone, a street multimedia terminal, or the like, or a function that allows an input operation with a user's hand or finger. It is realized by other similar devices provided. Hereinafter, a mouse cursor on a mouse or a touch pad, or a location where a user touches the display on a touch panel display device will be referred to as an “operation target point”.

  The trajectory calculation means A124 is specifically realized by a CPU of an information processing apparatus that operates according to a program. The trajectory calculation means A124 connects the series of movement directions and movement distances of the “operation target points” obtained as a result of the user operating the input means A123 one after another, thereby moving the “operation target points”. It has a function to calculate the trajectory.

  Specifically, the vibration monitoring unit A125 is realized by a CPU of an information processing apparatus that operates according to a program. The vibration monitoring unit A125 monitors the trajectory calculated by the trajectory calculating unit A124, and the fact that the “operation target point” has started to be moved by the user's hand (vibration start) and that the user's hand has stopped after the vibration has ended. (Vibration end) is detected. When the vibration monitoring means A125 detects the start of vibration, the “operation target point” indicates which of the XY planes the horizontal direction of the screen of the information processing terminal A20 is the X axis and the vertical direction is the Y axis. It has a function to calculate whether it has started moving in the direction (initial inclination).

  Specifically, the time correction means A126 is realized by a CPU of an information processing apparatus that operates according to a program. The time correction means A126 calculates the time difference between the clocks by exchanging the time information of the clock mounted on the pair management device 100 and the time information of the clock mounted on the information processing terminal A20, and originally the information processing terminal A20. Has a function of converting the time 231 stored as the time on the clock mounted on the watch to the time on the clock mounted on the pair management apparatus 100.

  The trajectory storage means A127 is specifically realized by a storage device such as a magnetic disk device or an optical disk device. The trajectory storage unit A127 stores a plurality of trajectories 230 and an initial inclination 234. The trajectory storage unit A127 stores, as the trajectory 220, the position on the XY plane of the “operation target point” calculated by the trajectory calculation unit A124 and the time at that time.

  As shown in FIG. 3, the locus 220 includes a time 231, an X coordinate 232, and a Y coordinate 233.

  Time 231 is the time when the locus calculation means A124 calculated the position of the “operation target point”. The time 231 is initially stored as the time on the clock mounted on the call terminal A10, but later converted to the time on the clock mounted on the pair management apparatus 100 and is overwritten and stored.

  The X coordinate 232 is the value of the X coordinate of the position of the “operation target point” on the XY plane at the time 231.

  The Y coordinate 233 is the value of the Y coordinate of the position of the “operation target point” on the XY plane at the time 231.

  The initial inclination 224 is calculated when the vibration monitoring unit A125 detects the start of vibration, and is information indicating in which direction on the XY plane the “operation target point” starts to move. Specifically, the initial inclination 224 corresponds to the inclination of a straight line when the direction in which the “operation target point” starts to move is expressed by a straight line passing through the origin of the XY plane.

  Next, the operation will be described. FIG. 4 is a flowchart illustrating an example of processing of the acceleration sensor-based pairing method. In the present embodiment, description will be made on the assumption that the user A owns the call terminal A10 and the information processing terminal A20, and the user B owns the call terminal B11 and the information processing terminal B21.

  First, when it is desired to perform pairing of the terminal, the user A operates the call terminal A10 to display a pairing execution screen. Then, the acceleration detection means A111 automatically starts detecting acceleration information along a time series. Next, the acceleration / speed conversion means A113 starts processing for converting the acceleration information along the time series detected by the acceleration detection means A111 into the speed information along the time series. Next, the trajectory calculation unit A114 starts processing to convert the speed information along the time series calculated by the acceleration / speed conversion unit A113 into a trajectory along the time series. The locus calculation process is continuously executed while the acceleration detection unit A111 detects acceleration information.

  Next, the vibration monitoring unit A115 starts a process of monitoring the start of the vibration operation by the user A based on the locus calculated by the locus calculating unit A114. Specifically, the vibration monitoring unit A115 first traces the latest position of the acceleration detection unit A111 (coordinates on the XY plane) and a predetermined time from the locus information calculated by the locus calculation unit A114. Two positions are obtained (extracted), the position of the obtained acceleration detecting means A111. Next, the vibration monitoring means A115 calculates the distance between the two positions, and determines whether or not it exceeds a predetermined value. Further, the call terminal A10 starts a timer.

  Next, the user A operates the information processing terminal A20 to perform an operation for displaying a screen for executing pairing. Then, the trajectory calculation unit A124 connects the series of movement directions and movement distances of the “operation target points” obtained as a result of the user operating the input unit A123, one after another, thereby obtaining the “operation target points”. The process of calculating the movement trajectory is started. The locus calculation process is continuously executed while the user operates the input unit A123.

  Next, the vibration monitoring unit A125 starts a process of monitoring the start of the vibration operation by the user A based on the locus calculated by the locus calculating unit A124. Specifically, the vibration monitoring unit A125 first obtains the latest position of the input unit A123 (coordinates on the XY plane) and a predetermined time from the information on the locus calculated by the locus calculating unit A124. Two positions, ie, the position of the input means A123 to be obtained are acquired (extracted). Next, the vibration monitoring unit A125 calculates the distance between the two positions and determines whether or not the distance exceeds a predetermined value. Thereafter, the user A takes the call terminal A10 onto the input means A123 and holds it together (step S300).

  When the predetermined time has elapsed, the timer of the call terminal A10 activated in step S300 times out, and the call terminal A10 starts a vibration operation to the user A by sounding an electronic sound or the like. Tell them that it ’s okay. As a notification means, instead of sounding a sound, if a display device or a sub-display device or the like is provided on the back of the call terminal A10, a message may be displayed on these display devices. Further, the vibration may be generated at the call terminal A10 using the vibrator function. In response to this, the user A starts to move the call terminal A10 and the input unit A123 left and right together (start vibration) (step S301).

  The vibration monitoring means A115 detects the start of vibration of the call terminal A10. Then, the vibration monitoring means A115 detects the start point of the vibration by detecting the start of vibration and the X-Y passing through the coordinates of the acceleration detection means A111 obtained by tracing back a predetermined time. The slope of the straight line on the Y plane is calculated, and the value is stored in the initial slope 224. In addition, the trajectory calculation unit A114 starts saving the time 221, the X coordinate 222, and the Y coordinate 223 to the trajectory 220 (step 302). Thereby, the locus | trajectory 220 is newly produced | generated one after another during the vibration operation of the user A. Here, the time 221 is a time on a clock mounted on the call terminal A10.

  Next, the vibration monitoring unit A115 starts processing for monitoring the end of the vibration operation by the user A based on the locus calculated by the locus calculating unit A114. Specifically, first, the vibration monitoring unit A115 acquires (extracts) two positions as in the process of step S300. Next, the vibration monitoring unit A115 calculates the distance between the two positions and determines whether or not the distance is below a predetermined value.

  The vibration monitoring unit A125 detects the start of vibration of the input unit A123. The vibration monitoring unit A125 stores the initial inclination 234 in the same manner as the vibration monitoring unit A115. In addition, the trajectory calculation unit A124 starts saving the time 231, the X coordinate 232, and the Y coordinate 233 to the trajectory 230. As a result, new trajectories 230 are successively generated during the vibration operation of the user A. Here, the time 231 is a time on a clock mounted on the information processing terminal A20.

  Next, the vibration monitoring unit A125 starts processing for monitoring the end of the vibration operation by the user A based on the trajectory calculated by the trajectory calculating unit A124. Specifically, first, the vibration monitoring unit A125 acquires (extracts) two positions in the same manner as in the process of step S300. Next, the vibration monitoring unit A125 calculates the distance between the two positions and determines whether or not the distance is below a predetermined value.

  The user A finishes moving the call terminal A10 and the input unit A123 left and right several times together, and stops moving (end of vibration) (step S303).

  The vibration monitoring means A115 detects the end of vibration of the call terminal A10. Then, the trajectory calculation unit A114 normalizes the X coordinate 222 and the Y coordinate 223 for all the trajectories 220. Even if the trajectory calculation unit A114 and the trajectory calculation unit A124 have different resolutions of the trajectory, the scale of the coordinates can be made uniform by this normalization process. Therefore, in step S307, the trajectory comparison unit 101 determines the trajectory of both terminals. Can be compared. Specifically, in this normalization process, the trajectory calculation unit A114 acquires (extracts) | maximum value | and | minimum value | for all the X coordinates 222, and sets each X coordinate 222 to (X Overwrite and save with the value of (coordinate 222) / (largest value of | maximum value | and | minimum value |). Here, | * | is the absolute value of *. For example, when maximum value = 20, minimum value = −30, and X coordinate 222 = 15, | minimum value | = 30 is larger than | maximum value | = 20, so 15 ÷ 30 = 0. 5 to overwrite. Similar processing is performed for the Y coordinate 223.

  Next, the time correction means A116 calculates the time difference between the clocks by exchanging the time information of the clock mounted on the pair management device 100 and the time information of the clock mounted on the call terminal A10. The method for calculating the time difference is described in, for example, a document (RFC 2030, “Simple Network Time Protocol (SNTP) Version 4 for IPv4, IPv6 and OSI”, October 1996, http://tools.ietf.org/rfc/rfc2030). .txt).

  Using the calculated time difference, the time correction unit A116 converts the time 221 stored as the time on the clock mounted on the call terminal A10 into the time on the clock mounted on the pair management device 100 and overwrites it. To do. For example, in the case where it is calculated that the clock mounted on the pair management apparatus 100 is delayed by 1 second from the clock mounted on the call terminal A10, the conversion processing is performed using the time 221 for all the trajectories 220. A process of delaying by 1 second is performed.

  Thereafter, the call terminal A10 transmits the identifier of the call terminal A10, the initial inclination 224, and all the trajectories 220 to the trajectory comparison means 101. Finally, the call terminal A10 updates the screen of the call terminal A10 and displays a message indicating that processing is in progress. In addition, the information processing terminal A20 performs the same process as the call terminal A10 (step S304).

  When the trajectory comparison unit 101 receives the initial inclination 224, the trajectory 220, the initial inclination 234, and the trajectory 230, the trajectory comparison unit 101 acquires (extracts) the first time 221 and time 231 from the trajectory 220 and the trajectory 230, and the time difference is obtained. Judge whether it is within the predetermined value. Further, the trajectory comparison unit 101 acquires (extracts) the last time 221 and time 231 and determines whether or not the time difference is within a predetermined value (step S305).

  If either one exceeds the predetermined value, the trajectory comparison unit 101 determines that the pair of the call terminal A10 and the information processing terminal A20 is not established (step S309). Thereafter, the trajectory comparing means 101 notifies both terminals of that fact, and the processing returns to the beginning as shown in FIG.

  When both are within the predetermined value, the trajectory comparison unit 101 extracts and extracts only the trajectory 220 and the trajectory 230 in which the time 221 and the time 231 overlap from the received trajectory 220 and the trajectory 230. Based on the trajectory 220 and the trajectory 230, a trajectory 210 is newly generated. Thereafter, as shown in FIG. 4, the process proceeds to step S306.

  Specifically, first, the trajectory comparison means 101 acquires (extracts) the later time of the first time 221 and the time 231, and the trajectory 220 having the time 221 earlier than this time, All the trajectories 230 having the earlier time 231 are discarded. Next, the trajectory comparison means 101 acquires (extracts) the earlier time among the last time 221 and time 231, the trajectory 220 having a time 221 later than this time, and a time 231 later than this time. All the trajectories 230 having are discarded. As a result, only the trajectory 220 and the trajectory 230 in which the time 221 and the time 231 overlap are left.

  By this process, even if the detection timing of the vibration start in step S302 and the vibration end in step S304 is not accurately synchronized between the call terminal A10 and the information processing terminal A20, the trajectory comparison unit 101 is as accurate as possible. In step S307, it is possible to determine the coincidence of the trajectories as if they were synchronized.

  Next, the trajectory comparison means 101 counts the number of the trajectories 220 and 230, calculates the value of (the larger number) / (the smaller number), and rounds off the decimal part. ". For example, when the number of trajectories 220 = 100 and the number of trajectories 230 = 50, “sampling speed ratio” = 100 ÷ 50 = 2.

  Next, the trajectory comparison unit 101 copies the larger one of the trajectories 220 and 230 to the trajectory 210. In the above example, 100 trajectories 210 are newly generated, values are filled in the time 211, the call terminal X coordinate 212, and the call terminal Y coordinate 213, and the information processing terminal X coordinate 214 and the information processing terminal Y coordinate 215 are The value is empty.

  Next, the trajectory comparison unit 101 copies the X coordinate and the Y coordinate of the trajectory 220 and the trajectory 230 with the smaller number to the trajectory 210. However, at the time of this copying, the trajectory 210 is extracted in ascending order of time 211 as many times as the “sampling speed ratio”, and the empty X coordinate and Y are extracted with respect to the extracted one or more trajectories 210. The X coordinate and Y coordinate of the smaller number of the trajectory 220 and the trajectory 230 are copied to the coordinates. In the example described above, two of the trajectory 210 with the first earliest time 211 and the trajectory 210 with the second earliest time are extracted, and both of the two information processing terminal X coordinates 214 have the trajectory 230 with the earliest time 231. The X coordinate 232 is copied, and the Y coordinate 233 of the locus 230 with the earliest time 231 is copied to both of the two information processing terminals Y coordinates 215. Sequentially, this process is performed on subsequent trajectories 210, such as trajectory 210 with the earliest time 211 and trajectory 210 with the fourth earliest time 211.

  By this processing, suppose that the number of times that the acceleration detecting unit A111 detects acceleration per unit time (sampling speed) and the number of times that the input unit A123 collects the position of the “operation target point” per unit time (sampling speed) However, even if they are different, the difference between the two sampling rates can be absorbed.

  The trajectory comparison unit 101 performs processing for converting the values of the call terminal X coordinate 212 and the call terminal Y coordinate 213 for all the trajectories 210 using the initial inclination 224 and the initial inclination 234 (step S306). The reason for performing this conversion process will be described with reference to FIGS. 5 and 6 are diagrams for explaining the reason why the coordinate system needs to be rotated. In the following description, it is assumed that the call terminal A10 is a mobile phone provided with an acceleration sensor, and the information processing terminal A20 is a PC provided with a mouse.

  As shown in FIGS. 5A and 5B, the mobile phone and the mouse have separate coordinate systems on the XY plane. In the case of a mobile phone, the position of the acceleration sensor is the origin of the coordinate system, and in the case of a mouse, the portion of the mouse where the ball contacts the ground is the origin of the coordinate system.

  Here, as shown in FIG. 5A, the user rarely holds the mobile phone and the mouse together so that the Y coordinate of the mobile phone and the Y coordinate of the mouse are exactly parallel to each other. it is conceivable that. Rather, as shown in FIG. 5B, in most cases, the user holds the mobile phone and the mouse together such that the two Y coordinates are not parallel.

  In the case of FIG. 5A, the trajectory comparing means 101 matches the trajectories of the mobile phone and the mouse in step S307 without particularly converting the values of the call terminal X coordinate 212 and the call terminal Y coordinate 213. It is thought that it will be judged. Therefore, there is no particular problem in this case.

  On the other hand, in the case of FIG. 5B, in step S307, the trajectory comparison unit 101 erroneously determines that the trajectories of the mobile phone and the mouse do not match. This is because (b-1) in FIG. 6 separates the coordinate system of the mouse and the coordinate system of the mobile phone and prevents the mobile phone coordinate system tilted in (b) from tilting. This is because the locus that starts to move in the 2 o'clock direction of the watch in the coordinate system of the mouse is the locus that starts to move in the 5 o'clock direction of the watch in the coordinate system of the mobile phone. As a matter of course, in this state, in step S307, it is determined that the two loci do not match, and an incorrect determination result is obtained.

  Therefore, the mobile phone coordinate system is rotated to be point-symmetric about the origin so that the mobile phone trajectory starting in the 5 o'clock direction becomes the trajectory starting in the 2 o'clock direction of the watch. To solve this problem. This rotation processing can be realized using a method widely known as “affine transformation”. That is, in this step, a process of converting the values of the call terminal X coordinate 212 and the call terminal Y coordinate 213 using “affine transformation” is performed.

  First, the trajectory comparison unit 101 uses the initial inclination 224 and the initial inclination 234 to calculate an angle for rotating the coordinate system of the call terminal A10. Next, the trajectory comparison unit 101 converts the values of the call terminal X coordinate 212 and the call terminal Y coordinate 213 using “affine transformation” for all the trajectories 210, and converts the converted values to the call terminal X coordinates. 212 and the call terminal Y coordinate 213 are overwritten and saved.

  The trajectory comparison unit 101 determines whether or not the trajectories match by comparing the trajectory of the call terminal A10 and the trajectory of the information processing terminal A20 in time series (step S307). FIG. 7 is an explanatory diagram schematically showing a comparison in time series of two trajectories. For simplification of description, the description will be made on the assumption that “sampling speed ratio” = 1.

  As shown in FIG. 7, the dotted line is the locus of the call terminal A10, and the solid line is the locus of the information processing terminal A20. The coordinates of the black dot on the dotted line are given by (call terminal X coordinate 212. call terminal Y coordinate 213), respectively. Similarly, the coordinates of the black point on the solid line are given by (information processing terminal X coordinate 214. information processing terminal Y coordinate 215), respectively. (Call terminal X coordinate 212. Call terminal Y coordinate 213) and (Information processing terminal X coordinate 214. Information processing terminal Y coordinate 215) having a common time 211 are connected by a straight line. Hereinafter, the length of each straight line is defined as “distance between tracks”.

  First, the trajectory comparison unit 101 calculates “distance between trajectories” for all the trajectories 210. Next, the trajectory comparison unit 101 calculates a ratio when the “distance between trajectories” is within a predetermined value with respect to the total number of trajectories 210. Then, the trajectory comparison unit 101 determines whether or not the calculated ratio is below a predetermined value.

  If the calculated ratio falls below the specified value, the trajectory comparison unit 101 determines that a pair of the call terminal A10 and the information processing terminal A20 is established (step S308). First, the trajectory comparing means 101 notifies both terminals of that fact. Next, the trajectory comparison unit 101 newly generates the pair 200 and stores the identifiers transmitted by the call terminal A10 and the information processing terminal A20 in step S304 as the call terminal identifier 201 and the information processing terminal identifier 202, respectively.

  If the calculated ratio does not fall below the specified value, the trajectory comparison unit 101 determines that the pair of the call terminal A10 and the information processing terminal A20 is not established (step S309). Thereafter, the trajectory comparing means 101 notifies both terminals of that fact, and the processing returns to the beginning as shown in FIG.

  Here, for example, let us consider a case where the timings of operations for vibrating the call terminal and the mouse between the user A and the user B overlap. Even in this case, the trajectory information received by the pair management device is different for each user. Therefore, the pair management device can form a pair of a call terminal held by each user with a mouse and an information processing terminal to which the mouse is connected, as intended by each user.

  As described above, according to the present embodiment, simple pairing can be performed without placing a heavy burden on the user during the pairing operation. The reason is that the user does not need to manually enter the phone number of his / her call terminal, and the user can hold his / her call terminal together with the mouse of his / her information processing terminal and vibrate. It is because it can do.

  Further, according to the present embodiment, it is possible to perform reliable pairing that can prevent a pair different from the user's intention from being formed. The reason is that even if the timing of the operation of vibrating the call terminals and mice of a plurality of users overlaps, the trace information of the call terminals and mouse obtained by vibration is compared in the pair management device to form a pair. This is because determining whether or not makes it possible to form a pair of a call terminal held together with the mouse by the user and an information processing terminal to which the mouse is connected as intended by the user.

  Furthermore, according to the present embodiment, there is an effect that a pair can be assembled even if the resolution of the trajectory calculated at the call terminal is different from the resolution of the trajectory calculated at the information processing terminal. (See step S304).

  Furthermore, according to this embodiment, the effect that a pair can be assembled even if the time of a call terminal and an information processing terminal is not synchronized beforehand is acquired. (See step S304).

  Furthermore, according to this embodiment, even if the detection timing of vibration start and vibration end is not accurately synchronized between the call terminal and the information processing terminal, an effect that a pair can be assembled is obtained. (See step S305).

  Furthermore, according to the present embodiment, there is an effect that a pair can be assembled even if the sampling speed of the acceleration detecting means A111 and the sampling speed of the input means A123 are not matched in advance. (See step S305).

  Furthermore, according to the present embodiment, there is an effect that a pair can be assembled even if the user does not bother the direction of the call terminal and the information processing terminal. (See step S306).

  In addition, the method described in Patent Document 2 has a problem in that an information processing terminal that does not include wireless communication hardware cannot perform pairing, and thus cannot implement a system at low cost. The reason is described in Patent Document 2 regarding remote control of a terminal such as a TV terminal or an HDD recorder terminal by a remote controller. If the terminal is replaced with an information processing terminal such as a PC, the desktop PC usually does not include hardware for wireless communication. Therefore, if the method described in Patent Document 2 is used, the desktop PC performs pairing. It is because it is not possible. Therefore, in order to enable pairing even with a desktop PC, it is necessary to purchase an expansion board for wireless communication. As a result, the system cannot be realized at low cost.

  According to the present embodiment, even an information processing terminal that does not include hardware for wireless communication can perform pairing, and an inexpensive pairing method can be provided. This is because the information processing terminal does not need to have wireless communication hardware for communication, and can communicate using wired communication such as a LAN.

  Next, an embodiment of the present invention will be described with reference to FIGS. When the user A performs pairing between the call terminal A10 and the information processing terminal A20, what kind of screen transition occurs or what kind of operation is performed will be described with reference to FIG. FIG. 8 is an explanatory diagram showing a screen example and an operation example.

  FIG. 8A is a pairing execution screen displayed by the user A operating the call terminal A10 and the information processing terminal A20 in step S300.

  FIG. 8B shows an operation in which the user A vibrates the call terminal A10 and the input unit A123 left and right together in step S301.

  FIG. 8 (3) is a screen displaying a message indicating that the call terminal A10 and the information processing terminal A20 are processing in step S304.

  FIG. 8 (4) is a screen on which a message indicating that a pair has been established is displayed between the call terminal A10 and the information processing terminal A20 in step S308.

  FIG. 9 is an explanatory diagram showing how to pair an information processing terminal having input means other than a mouse.

  As shown in FIG. 9 (5), when pairing an information processing terminal equipped with a touch pad such as a notebook PC and a call terminal, hold the call terminal with the hand and use the thumb or middle finger of the same hand. The touchpad can be operated.

  As shown in FIG. 9 (6), when pairing an information processing terminal equipped with a touch panel display device such as a PDA, a smartphone, or a street multimedia terminal with a call terminal, while holding the call terminal by hand, The touch panel display device may be operated with the thumb or middle finger of the same hand.

  Next, the minimum configuration of the acceleration sensor-based pairing system according to the present invention will be described. FIG. 10 is a block diagram showing a minimum configuration example of the acceleration sensor-based pairing system. As shown in FIG. 10, the acceleration sensor-based pairing system includes a first terminal 10 equipped with an acceleration sensor, a second terminal 20, and a pair management device 100 as the minimum components. The first terminal 10 includes a first terminal trajectory calculation unit A114, the second terminal 20 includes a second terminal trajectory calculation unit A124, and the pair management apparatus 100 includes a trajectory comparison unit 101 and including.

  In the acceleration sensor-based pairing system with the minimum configuration shown in FIG. 10, the first terminal trajectory calculating means A114 is based on the acceleration information detected by the acceleration sensor when the first terminal 10 is moved by the user. A function of calculating trajectory information indicating the trajectory of the movement of the first terminal 10 is provided. Further, the second terminal trajectory calculating means A124 performs input at the second terminal 20 when the user performs an input operation from the second terminal 20 in conjunction with the movement of the first terminal 10. A function of calculating trajectory information indicating the trajectory of coordinates is provided. The trajectory comparing means 101 compares the trajectory information calculated by the first terminal trajectory calculating means with the trajectory information calculated by the second terminal trajectory calculating means, thereby comparing the first terminal 10 with the first terminal 10. A function of determining whether or not to pair with the second terminal 20 is provided.

  According to the pairing method using the acceleration sensor with the minimum configuration shown in FIG. 10, the pair management device 100 compares the trajectory information received from the first terminal 10 with the trajectory information received from the second terminal 20. If it is determined that the two pieces of trajectory information are close, a pair of the first terminal 10 and the second terminal 20 is established. Therefore, pairing can be easily performed without burdening the user such as inputting a number. In addition, for example, even when the timings of operations for vibration of a plurality of users overlap, the trajectory information received by the pair management apparatus 100 differs for each user. Therefore, the first terminal 10 and the second terminal 20 can be reliably paired as intended by the user.

  In addition, in said embodiment and Example, the characteristic structure of the acceleration sensor utilization pairing method as shown to the following (1)-(7) is shown.

When the input operation from the second terminal (for example, realized by the information processing terminal A20) is performed by the user in conjunction with the movement of the first terminal, the second terminal Trajectory calculation step for second terminal (for example, trajectory calculating means A124) for calculating trajectory information (for example, trajectory 230) indicating the trajectory of the input coordinates.

(2) In the pairing method using the acceleration sensor, the movement position (for example, the X coordinate 222 and the Y coordinate 223) to which the first terminal has moved in the first terminal locus calculation step and the first terminal to the movement position The trajectory information including the time (for example, time 221) associated with the movement of the second terminal is calculated, and the movement position (for example, the X coordinate 232 and the Y coordinate 233) at which the second terminal has moved in the second terminal trajectory calculation step. ) And the time at which the second terminal moves to the moving position (for example, time 231) in association with each other, the trajectory information for the first terminal at the same time is calculated in the pairing determination step. When it is determined that the difference between the movement position included in the calculated trajectory information and the movement position included in the trajectory information calculated by the second terminal trajectory calculation means is within a predetermined distance, the first terminal and the second terminal It may be configured to determine that the terminal is paired.

(3) The acceleration sensor-based pairing method displays a pairing execution screen on the first terminal and the second terminal, holds the input means of the first terminal and the second terminal together, An acceleration sensor-based pairing method for performing pairing between the first terminal and the second terminal based on an operation of vibrating one terminal and the input means, wherein the first terminal and the input means A vibration monitoring step (for example, realized by the vibration monitoring means A115) that detects the start of vibration operation, calculates an initial inclination between the first terminal and the second terminal, and starts storing the trajectory information; When the operation of vibrating the first terminal and the input unit is completed, the end of the vibration operation between the first terminal and the input unit is detected (for example, realized by the vibration monitoring unit A115), and the stored locus Normalize the X and Y coordinates of the information The time difference between the clock mounted on the first terminal and the clock mounted on the pair management device is calculated, and the storage time of the trajectory information is converted into the time on the clock mounted on the pair management device based on the calculated time difference (for example, , Realized by the time correction means A116), a transmission step for transmitting the initial inclination (for example, the initial inclination 224) and the trajectory information to the pair management device, and the difference between the vibration start time and the vibration based on the received trajectory information. A time difference determination step (for example, realized by the trajectory comparison means 101) for determining whether the difference between the end times is within a predetermined value, and a coordinate system rotation step for rotating the coordinate system of the first terminal using the initial inclination. By determining whether or not the trajectory information of the first terminal and the second terminal matches (for example, realized by the trajectory comparison unit 101), the first terminal and the second terminal pair Pair determination step of determining whether or not to establish (e.g., as implemented by the trajectory comparing means 101), characterized in that it comprises a.

(4) In the acceleration sensor-based pairing method, the trajectory information of the first terminal and the trajectory information of the second terminal are each in the form of a series of pairs of storage times and points on the XY plane. In the pair determination step, the distance between the first terminal point and the second terminal point having a common storage time for a series of points is calculated (for example, the distance between trajectories), and the total number of pairs is calculated. On the other hand, the ratio when the distance is within the predetermined value is calculated, and when the calculated ratio is lower than the predetermined value, it is determined that the pair of the first terminal and the second terminal is established, and when it is higher, It may be configured to determine that the pair is not established.

(5) In the acceleration sensor pairing method, in the coordinate system rotation step, in the coordinate system of the XY plane between the first terminal and the second terminal, the inclination passes through the origin of the XY plane and the first inclination For a straight line expressed by the initial inclination value of the terminal and a straight line that passes through the origin of the XY plane and whose inclination is expressed by the initial inclination value of the second terminal, one straight line is pointed around the origin. It is configured to calculate the angle required to match the other straight line by rotating so that it is symmetrical, and to rotate one coordinate system by the angle so that it is point-symmetric about the origin. Also good.

(6) In the acceleration sensor-based pairing method, the trajectory information of the first terminal and the trajectory information of the second terminal are each in the form of a series of pairs of storage times and points on the XY plane. In the time difference determination step, the number of pairs constituting the trajectory information of the first terminal and the pair constituting the trajectory information of the second terminal is counted, and (the larger number) / (the smaller number) When calculating the distance between the first terminal point and the second terminal point having a common storage time, the first decimal point is rounded down to the sampling rate ratio. Among the terminals of the first terminal and the second terminal, one point of the locus information of the terminal having the smaller number of sets constituting the locus information is extracted in order from the oldest storage time, and the locus information of the terminal having the larger number is extracted. Extract points as many as indicated by the sampling rate ratio in order of age. And 1 point taken out from the side number is small, the process of obtaining the distance between the points extracted from the side number is large, the retention time may be configured to repeat the oldest.

In the pair determination step, it is determined whether or not the trajectory information between the first terminal and the second terminal matches based on the extracted trajectory information of the first terminal and the trajectory information of the second terminal. It may be configured as follows.
