Description

  The present invention relates to an information processing apparatus that is mounted on a mobile body, and relates to an information processing apparatus that allows a user to easily operate, and more particularly, to an apparatus that can be operated without the user gazing at an operation unit or a screen.

  Conventionally, various interfaces that can be easily operated by a user in an information processing apparatus such as a navigation apparatus have been proposed.

  In navigation devices, a monitor with a touch panel and a remote controller are widely used, and the user can easily perform operations. However, in the input interface of a touch panel or a remote controller, it is dangerous for the driver to perform the operation while driving because the hand must be released from the steering wheel in order to perform the operation. At present, it is prohibited to operate the navigation device while driving.

There has also been proposed a navigation device in which an operation panel is provided on a steering wheel and a driver can operate without releasing his / her hand from the steering wheel. For example, Patent Document 1 discloses an information operation device that is intended to enable an operation intended by a user to be performed smoothly without a sense of incongruity. In this information operating device, an operation panel is attached to the steering. When the driver touches the operation panel while holding the steering wheel, a contact area corresponding to each selection item is set on the operation panel with the position touched first as the center. Thus, the driver can select the selection item by touching the periphery around the position touched first.
JP 2005-119540 A

  However, in the information operation device described in Patent Document 1, it is necessary to remember the position where the user first touched, and when the position touched first is forgotten, the selection item is appropriately set. I can't touch it. Patent Document 1 also describes that an indicator corresponding to the ordinate and abscissa of the center is turned on in order to indicate the position touched first. However, in order to confirm the position corresponding to the display center of the selected item from the indicator on the operation panel, it is necessary to look closely at the operation panel, and there is a problem because it is necessary to keep an eye on the front of the vehicle during that time.

  In view of the above background, an object of the present invention is to provide an information processing apparatus that allows a user to easily perform an operation without gazing at an operation unit or a screen.

  An information processing apparatus according to the present invention is an information processing apparatus mounted on a moving body, and includes an image output unit, an operation unit that continuously receives input of position information from a user, and an operation specified by a movement path of the input position. An operation pattern storage unit storing a pattern and a process corresponding to the operation pattern, and an operation for determining whether the movement path of the input position received by the operation unit matches the operation pattern stored in the operation pattern storage unit A pattern determination unit; and a screen control unit that performs screen control of the image output unit according to a process corresponding to the operation pattern when it is determined that the movement path of the input position matches the operation pattern.

  Thus, by performing screen control based on the operation pattern defined by the movement path of the input position, it is possible to perform an operation without paying attention to the operation unit or the screen. That is, according to the present invention, the process is determined by the relative movement path pattern of the input position, not the position of the operation unit or the screen, so that the operation unit or the screen is not watched. Can be operated. In the present invention, that the movement path of the input position “matches” the operation pattern means that the similarity between the movement path of the input position and the operation pattern is higher than a predetermined threshold. The operation pattern stored in the operation pattern storage unit defines the shape of the movement path and does not define the size. Therefore, for example, when the operation pattern is a circle, the movement path of the input position matches the operation pattern regardless of whether it is a circle with a radius of 3 cm or a circle with a diameter of 5 cm.

  The information processing apparatus of the present invention may include a notification sound output unit that outputs a notification sound that notifies that the movement path of the input position matches the operation pattern.

  With this configuration, it is possible to know from the notification sound that the movement path of the input position matches the operation pattern, so it is only necessary to view the screen after the notification sound is output, so that it is not necessary to look at the screen until then. It becomes possible to operate.

  In the information processing apparatus of the present invention, the notification sound output unit may output different notification sounds depending on the type of operation pattern that matches the movement path of the input position.

  Thus, by changing the type of the notification sound, it is possible to know which operation pattern is matched without looking at the screen.

  In the information processing apparatus of the present invention, the screen control unit may perform the following control. That is, when the operation pattern determination unit determines that the movement path of the input position matches (1) the operation pattern corresponding to the activation process, a screen having a plurality of selection items is displayed. When it is determined that the operation pattern corresponding to the process is matched, the selection items displayed on the screen are sequentially instructed, and (3) the operation pattern corresponding to the confirmation process is selected with any of the selection items being instructed. When it is determined that they match, the selection of the instructed selection item is confirmed. (4) When it is determined that the operation pattern corresponding to the cancel processing is matched, the display on the screen is cleared.

  Thus, the screen control unit has an operation pattern corresponding to each of the activation process, the selection process, the confirmation process, and the cancellation process, and when the operation pattern matches each operation pattern, Each of the above processes can be performed without paying attention to the section and the screen.

  When the operation unit is a touch pad, the operation pattern storage unit stores an operation of moving a finger away from the touch pad or an operation of pressing the touch pad with a pressure equal to or higher than a predetermined threshold as an operation pattern corresponding to the confirmation process. In addition, the confirmation process may be detected.

  With this configuration, a process can be selected by moving a finger and drawing a predetermined movement path, and then can be confirmed by releasing the finger from the touch pad or pressing the touch pad strongly. A smooth interface can be realized.

  In the information processing apparatus of the present invention, when it is determined that the operation pattern corresponding to the confirmation process is matched, the selection process is performed using the information on the movement path of the input position input when the selection items are sequentially specified. The corresponding operation pattern may be updated.

  With this configuration, the operation pattern corresponding to the selection process can be learned for each user. By making it possible to determine the processing with an operation pattern suitable for each user, a quick and appropriate operation can be performed even when a user operating the moving body operates, contributing to safe driving.

  When the information processing apparatus of the present invention does not detect a match between the movement path of the input position and the operation pattern for a predetermined time, the screen control unit stores the displayed screen as a pending screen, and The display may be cleared and the pending screen may be displayed during the next activation process.

  With this configuration, when no operation pattern is input, the screen display is automatically cleared and the process can be resumed at the next startup.

  In the information processing apparatus according to the present invention, the operation unit may be provided at a position where the user can operate the user while grasping the steering of the moving body.

  With this configuration, it is possible to operate without removing the hand from the steering wheel. Furthermore, by attaching the screen to the meter portion or using a head-up display, it is possible to operate safely because it is not necessary to keep an eye on the front when viewing the screen.

  The information processing apparatus of the present invention includes an input position history storage unit that stores position information input from the operation unit, and the operation pattern determination unit reads position information in a predetermined period from the input position history storage unit. A process of forming a movement route in the predetermined period and comparing the movement route with an operation pattern stored in the operation pattern storage unit may be sequentially performed.

  With this configuration, it is possible to properly compare sequentially input position information and operation patterns.

  An information processing method of the present invention is an information processing method of an information processing device mounted on a mobile object, and stores an operation pattern defined by an input position movement path and a process corresponding to the operation pattern. A step of preparing a unit, a step of continuously receiving input of position information from the user by the operation unit, and a movement path of the input position received by the operation unit matches the operation pattern stored in the operation pattern storage unit And a step of performing screen control according to a process corresponding to the operation pattern when it is determined that the movement path of the input position matches the operation pattern.

  With this configuration, since the screen control is performed based on the operation pattern defined by the movement path of the input position, the operation can be performed without gazing at the operation unit or the screen. Various configurations of the information processing apparatus of the present invention can be applied to the information processing method of the present invention.

  A program according to the present invention is a program for performing screen control of an information processing device mounted on a mobile body, the computer continuously receiving input of position information from a user by an operation unit, and the operation unit It is determined whether or not the movement path of the input position received in step 4 matches the operation pattern stored in the operation pattern storage unit that stores the operation pattern defined by the movement path of the input position and the processing corresponding to the operation pattern. When it is determined that the movement path of the input position matches the operation pattern, a step of performing screen control according to a process corresponding to the operation pattern is executed.

  With this configuration, since the screen control is performed based on the operation pattern defined by the movement path of the input position, the operation can be performed without gazing at the operation unit or the screen. Various configurations of the information processing apparatus of the present invention can be applied to the program of the present invention.

  With this configuration, the screen control is performed based on the operation pattern defined by the movement path of the input position, so that an operation can be performed without gazing at the operation unit or the screen.

  Hereinafter, an information processing apparatus according to an embodiment of the present invention will be described with reference to the drawings. Hereinafter, a vehicle will be described as an example of a moving body on which the information processing apparatus is mounted. However, the information processing apparatus of the present invention can be mounted on a moving body other than the vehicle.

  FIG. 1 is a diagram illustrating a configuration of an information processing apparatus 1 according to the embodiment. The information processing apparatus 1 according to the present embodiment is mounted on a vehicle and cooperates with various vehicle-mounted devices 30. The information processing apparatus 1 includes a touch pad 10 that receives input from a driver, an operation content analysis unit 12 that analyzes operation content input from the touch pad 10, and a monitor that performs output to the driver according to the input operation content. 18 and the speaker 22, and a screen control unit 20 and a notification sound control unit 24 for controlling the monitor 18 and the speaker 22, respectively. Note that the operation content analysis unit 12, the screen control unit 20, and the notification sound control unit 24 indicate the functions of the information processing apparatus 1. In an actual apparatus, the CPU executes a program stored in a ROM or the like. Thus, these functions are realized. A program for realizing the functions of the information processing apparatus 1 is also included in the scope of the present invention.

  The vehicle-mounted device 30 that cooperates with the information processing apparatus 1 of the present embodiment includes a navigation device 32, an air conditioner 34, an audio 36, and a telephone 38. Note that the vehicle-mounted device 30 illustrated in FIG. 1 is an example, and the vehicle-mounted device 30 that can cooperate with the information processing apparatus 1 is not limited to the example illustrated in FIG. For example, the information processing apparatus 1 can also cooperate with a device that controls opening / closing of a window or a device that controls lighting of a headlight.

  FIG. 2 is a diagram illustrating a state where the information processing apparatus 1 according to the present embodiment is mounted on a vehicle. As shown in FIG. 2, the touch pad 10 is attached to the steering 40. FIG. 2 shows an example in which the steering wheel 40 is attached to the right side, but the attachment position is not limited to the right side. The monitor 18 is attached to the meter attachment portion 42. The monitor 18 may be the same as the monitor of the navigation device 32.

  The operation content analysis unit 12 includes an input signal reception unit 14 and an operation pattern determination unit 16. The input signal receiving unit 14 has a function of receiving a signal indicating position information input from the touch pad 10 and storing the position information instructed by a finger from the received signal in the input position history storage unit 26. The processing performed by the input signal receiving unit 14 will be specifically described. When the input signal receiving unit 14 receives the object detection signal from the touch pad 10, the input signal receiving unit 14 obtains the contact area or the shape of the contact surface of the object from the received detection signal, and determines whether or not the touching object is a human finger. Determine. By this determination, it is possible to prevent erroneous detection caused by unintentionally touching the touch pad 10 with the palm of the driver who is grasping the steering wheel. When the input signal receiving unit 14 detects that the touching object is a human finger, the input signal receiving unit 14 calculates the representative coordinates of the finger. As the representative coordinates, the coordinates of the center of the contacting portion may be used, or the coordinates of the center of gravity may be used.

  The operation pattern determination unit 16 reads out data stored in the input position history storage unit 26 and stores it in a movement route calculated from the read data and an operation pattern database (hereinafter referred to as “operation pattern DB”) 28. Compare the operation pattern. Whether or not the movement route matches the operation pattern is determined based on whether or not the similarity between the two is equal to or greater than a predetermined threshold. The calculation of the similarity can be performed using principal component analysis and distance calculation used for handwritten character recognition, for example. The feature (vector) of the movement path input by the principal component analysis and the feature (vector) of the pattern stored in the operation pattern DB 28 are extracted, and the distance between both features (vector) is calculated by distance calculation. And when this distance is below a predetermined threshold value, it determines with both patterns being similar. Principal component analysis and distance calculation are described in, for example, Matsumoto and Nakagawa “Improvement of Large Classification Method for Online Handwritten Japanese Character Recognition” IEICE Technical Report, PRMU2001-273, March 2002. Has been.

  FIG. 3 is a diagram illustrating an example of data stored in the operation pattern DB 28. The operation pattern DB 28 stores operation patterns and processing contents corresponding to the operation patterns. As shown in FIG. 3, the operation pattern of the movement route that makes a reciprocation twice and a half is associated with the activation process. Therefore, when the operation pattern of the moving path that reciprocates twice and a half is matched, it is determined that the activation process has been input, and the determination result is sent to the screen control unit 20. In FIG. 3, the reciprocating direction is described as horizontal, but it is not related to the direction of the touch pad 10. In other words, regardless of whether the reciprocating movement path is vertical or oblique, the movement path that reciprocates twice and a half matches this operation pattern. This is the same for other operation patterns.

  Here, other operation patterns stored in the operation pattern DB 28 will also be described. The operation pattern of the movement path where the input position draws a circle is associated with the selection process. Although FIG. 3 shows an operation pattern for drawing a clockwise circle, the counterclockwise case may be associated with the selection process. In the case of counterclockwise rotation, it is possible to associate with another process.

  The movement pattern of the input position is interrupted, that is, the operation pattern for releasing the finger is associated with the confirmation process. An operation pattern in which the movement path of the input position is out of the touch panel in a straight line is associated with the cancel process.

  The operation pattern determination unit 16 sequentially reads input position information in a predetermined period (for example, 1 second) set in advance, a movement route calculated from the read data, and any pattern stored in the operation pattern DB 28 It is sequentially determined whether or not they match.

  FIG. 4A is a diagram illustrating an example of data stored in the input position history storage unit 26. Actually, the input position history storage unit 26 stores the data of the input position in the form of representative coordinates at each time, but in FIG. 4A, the input at each time is shown so that the movement route is easy to understand. The position is shown on the plane. In the example shown in FIG. 4A, the input position detected first at time t <b> 1 and detected every 0.1 second is shown below.

  For example, the operation pattern determination unit 16 sequentially reads input position coordinate information for one second. First, input position coordinate information at time t1 to t10 is read out, and it is determined whether or not the operation pattern is matched. Next, the input position coordinate information at time t2 to t11 is read out, and it is determined whether or not it matches the operation pattern. Thereafter, this process is repeated. In the example illustrated in FIG. 4A, it is determined that the movement path for one second from time t <b> 6 to t <b> 15 matches the “select” operation pattern. In this way, by sequentially reading data from the input position history information storage unit 26 and making a determination, the determination of the pattern is prompted when the finger movement is completed, or the driver once lifts the finger from the touch pad 10. The operation pattern can be determined without it. As a result, a smooth user interface can be realized without interrupting the flow of operation to start the determination of the operation pattern.

  FIG. 4B is a diagram showing a movement path similar to FIG. FIG. 4B differs from FIG. 4A in the input position on the touch pad 10, but, like FIG. 4A, has a circular movement path and matches the “select” operation pattern. Then, it is determined. That is, the operation pattern determination unit 16 detects the operation pattern regardless of which position on the touch pad 10 is touched.

  The screen control unit 20 controls the screen of the monitor 18 based on the determination result of the operation pattern determination unit 16. The screen control unit 20 has a function of displaying an initial screen or a pending screen that has been pending during the previous operation when an operation pattern for activation processing is input from the operation pattern determination unit 16. The screen control unit 20 performs display for sequentially instructing selection items when an operation pattern for selection processing is input. Further, when the confirmation process operation pattern is input, the screen control unit 20 confirms selection of the designated selection item, and performs processing corresponding to the selection item. For example, the screen control unit 20 displays the next selection screen according to the selection item or issues an instruction indicated in the selection item to the vehicle-mounted device 30. When the confirmation process is input when the selection process is not performed, the screen control unit 20 discards the input of the confirmation process and waits for the next instruction. This prevents the information processing apparatus 1 from malfunctioning when the driver inadvertently removes his / her finger from the touch pad 10.

  The notification sound control unit 24 has a function of outputting a notification sound when the operation pattern determination unit 16 determines that the movement path of the input position matches the operation pattern. By notifying the match between the movement path and the operation pattern with the notification sound in this way, the driver can know that the movement path of the input position matches the operation pattern without gazing at the monitor 18. Thus, the driver does not need to look at the monitor 18 until the notification sound is output, and can contribute to safe driving. Note that the notification sound control unit 24 may output the same notification sound regardless of the operation pattern, or may output different notification sounds depending on the operation pattern. If different notification sounds are output according to the operation pattern, the driver can conveniently find the matched operation pattern only with the notification sound. For example, when the driver matches an unintended operation pattern, the driver can cancel without watching the monitor 18.

  The notification sound control unit 24 can output the notification sound at various timings as well as when the movement path of the input position matches the operation pattern. For example, when performing the selection process, the notification sound control unit 24 may output different notification sounds according to the item selected at the timing when the item is selected. Thereby, it can be known which selection item was selected by the notification sound. In addition, the notification sound control unit 24 may output a different notification sound according to the designated selection item while the selection items are sequentially designated in the selection process. Different notification sounds may be output depending on the selection item instructed when the operation stops. With this configuration, it is possible to know which selection item is instructed by the notification sound, so that it becomes possible to select a desired item without looking at the monitor 18 as the user gets used to it.

  FIG. 5 is a flowchart showing the operation of the information processing apparatus 1 according to the present embodiment. The operation of the information processing apparatus 1 will be described with reference to FIG. When the information processing apparatus 1 detects a touch on the touch pad 10 (S10), the information processing apparatus 1 determines whether or not the state when the touch is detected is that the screen is being activated (S12). In the present embodiment, the information processing apparatus 1 determines whether or not the activation flag is turned on. If the activation flag is not turned on (NO in S12), that is, if the screen is not activated, activation processing is performed.

  FIG. 6 is a flowchart showing the operation of the activation process of the information processing apparatus 1. The information processing apparatus 1 determines whether an operation pattern corresponding to the activation process has been input (S40). The information processing apparatus 1 repeatedly performs this determination until an operation pattern corresponding to the activation process is input. In this way, the information processing apparatus 1 can be prevented from malfunctioning by activating the screen after waiting for the input of the operation pattern corresponding to the activation process.

  When the operation pattern determination unit 16 of the information processing apparatus 1 detects an operation pattern corresponding to the activation process, the operation pattern determination unit 16 notifies the notification sound control unit 24 and the screen control unit 20 that the operation pattern has been detected. The notification sound control unit 24 outputs a notification sound to notify the driver that an operation pattern corresponding to the activation process has been detected (S42). The screen control unit 20 determines whether there is a pending screen (S44). When it is determined that there is no pending screen (NO in S44), the screen control unit 20 displays an initial screen (S46). When it is determined that there is a pending screen (YES in S44), the screen control unit 20 displays the pending screen (S48).

  The information processing apparatus 1 turns on the activation flag after displaying the initial screen or the pending screen (S50). As a result, when the driver touches the touch pad 10 again after releasing his hand, the activation flag is turned on, so the activation process is skipped.

  Returning to FIG. 5, the operation of the information processing apparatus 1 after the activation process will be described. After the activation process, the operation of the information processing apparatus 1 returns to the position “B” in the flowchart of FIG. The operation pattern determination unit 16 of the information processing apparatus 1 detects the operation pattern stored in the operation pattern DB 28 (S14). When a movement route that matches any of the patterns stored in the operation pattern DB 28 is detected, the notification sound control unit 24 outputs a notification sound to notify that it matches the operation pattern (S16).

  Next, the operation pattern determination unit 16 sends the detected operation pattern to the screen control unit 20, and the screen control unit 20 performs an operation according to the operation pattern. The screen control unit 20 determines what the pattern sent from the operation pattern determination unit 16 is (S18). Here, when it is determined that the moving longitude of the input position goes out of the touchpad 10 in a straight line and matches the “cancel” operation pattern, the information processing apparatus 1 turns off the activation flag (S36). End the screen control.

  When it is determined that the movement path of the input position draws a circle and matches the “select” operation pattern, the screen control unit 20 sequentially instructs the selection items (S20). After detecting the “select” operation pattern, the information processing apparatus 1 returns to step S14 of detecting the next pattern.

  If it is determined that the finger is released from the touch pad 10 and matches the “confirm” operation pattern, the information processing apparatus 1 learns the operation pattern (S22), and then instructs when the confirmation is detected. The selection of the selected item is confirmed (S24).

  Here, the learning of the operation pattern will be described. When the information processing device 1 detects the “confirm” operation pattern, the information processing device 1 learns the operation pattern stored in the operation pattern DB 28 using information on the movement path of the finger of the driver when the “select” operation pattern is input. I do. In other words, in the present embodiment, if the operation pattern and the movement path of the input position and the degree of similarity are equal to or greater than a predetermined threshold, it is determined that both match, so even when it is determined that both match The movement path of the input position does not always follow the same locus as the operation pattern. By learning the operation pattern using the movement path actually input by the driver as a teacher signal, an appropriate operation pattern DB 28 can be generated in consideration of the driver's habit. For example, when inputting an operation pattern for selection processing, an operation pattern can be appropriately detected for a driver having a habit of drawing an elliptical circle by making the operation pattern corresponding to the selection processing elliptical. . When the information processing apparatus 1 is mounted on a vehicle and used as in the present embodiment, the driver cannot perform an operation while gazing at what kind of moving path the finger is, so that it is set in advance. It is difficult to follow exactly the same movement path as the operation pattern. Therefore, it is desirable to generate an operation pattern suitable for each driver by a configuration for learning the operation pattern.

  When the screen control unit 20 confirms the selection of the designated item, the screen control unit 20 performs processing corresponding to the confirmed selection item. When the selected item is an item for displaying the next menu screen, the screen control unit 20 displays the next menu screen. When the selected item is an item for controlling the vehicle-mounted device 30, the screen is displayed. The control unit 20 transmits a control instruction to the corresponding on-vehicle device 30.

  This will be described with reference to the flowchart of FIG. After confirming the selected item (S24), the screen control unit 20 determines whether there is a screen following the item (S26). That is, it is determined whether the menu screen continues or whether the menu screen ends and an instruction is given to the vehicle-mounted device 30.

  When it is determined that there is a next screen following the selected item (YES in S26), the screen control unit 20 displays the next screen corresponding to the selected item (S28), and after the screen is displayed. It is determined whether or not there is a touch on the touchpad 10 within a certain time (S30). If there is a touch on the touchpad 10 within a certain time (YES in S30), the information processing apparatus 1 proceeds to step S14 for detecting an operation pattern. If there is no touch on the touchpad 10 within a predetermined time (NO in S30), the information processing apparatus 1 stores the displayed screen as a pending screen (S32), and turns off the activation flag (S36). End the operation. As a result, when the operation cannot be continued due to the driving situation or the like, the information processing apparatus 1 can temporarily stop the operation and resume the operation from the pending screen instead of the main menu when the activation process is performed next time.

  If it is determined that there is no next screen following the selected item (NO in S26), the screen control unit 20 issues a control instruction to the vehicle-mounted device 30 corresponding to the selected item (S34). ). Then, after issuing a control instruction to the vehicle-mounted device 30, the activation flag is turned off (S36), and the operation of the information processing apparatus 1 is completed. In the example illustrated in FIG. 5, the example in which the operation instruction of the information processing apparatus 1 is ended by turning off the activation flag after giving the control instruction to the vehicle-mounted device 30 has been described. Thereafter, the screen may be changed to the initial screen and another process may be performed subsequently.

  7 and 8 are diagrams describing examples of patterns detected when the information processing apparatus 1 operates according to the above-described flow and screen control. When the information processing apparatus 1 detects a two-and-a-half-way reciprocation path following the detection of the touch, the information processing apparatus 1 determines that the activation process pattern has been input, and outputs a notification sound indicating that the operation pattern has been matched. The main menu 50 is displayed as a screen. The main menu 50 has three selection items, audio, navigation, and air conditioner, from which the driver selects a desired item.

  When the movement path of the input position draws a circle with the main menu 50 displayed, it is determined that the input pattern matches the “select” operation pattern, and a notification sound indicating that it matches the operation pattern is output, and the selection item The process of instructing each selection item in turn is started by the triangular mark 52 instructing. When the screen control unit 20 detects a movement path for drawing a circle after detecting the “select” operation pattern, the screen control unit 20 sequentially changes the indication position of the selection item at a speed according to the rotation speed.

  When the finger is removed from the touch pad 10 after the “select” process is performed, it is determined that the operation pattern corresponding to “confirm” is matched, and a notification sound indicating that the operation pattern is matched is output, and Confirm the selection of the selected item, sometimes “Navigation”. The screen control unit 20 displays a menu selection screen 54 for the selected “navigation”.

  The description will be continued with reference to FIG. When the “navigation” menu selection screen 54 is displayed and the touch is made again within a certain period of time, and the movement path of the input position draws a circle, it is determined that the operation pattern of “selection” is met, and the operation pattern is matched. A notification sound indicating that the selection has been made is output, and a triangular mark 52 indicating a selection item starts a process of sequentially specifying each selection item.

When the finger is removed from the touch pad 10 after the “select” process is performed, it is determined that the operation pattern corresponding to “confirm” is matched, and a notification sound indicating that the operation pattern is matched is output. The selection item instructed at that time, here, the selection of “map display” is confirmed. The screen control unit 20 displays a map 46 around the vehicle on the monitor 18 of the navigation device 32 in response to the selection of “map display”. When the navigation device 32 and the monitor 18 of the information processing device 1 are common, the map 46 may be displayed on the monitor 18 provided in the meter unit. In the present embodiment, the displayed map can be moved by moving a finger on the touch pad 10.
The information processing apparatus 1 according to the embodiment has been described above.

  When it is determined that the movement path of the position input to the touch pad 10 matches the predetermined operation pattern, the information processing apparatus 1 according to the present embodiment performs screen control corresponding to the operation pattern or instructions to the vehicle-mounted device 30. Therefore, the driver can easily perform the operation without gazing at the touch pad 10 or the monitor 18.

  In the information processing apparatus 1 according to the present embodiment, the touch pad 10 is touched, the finger is moved so as to form a predetermined movement path, and the operation can be performed with a simple and smooth movement in which the finger is released and confirmed. .

  In the information processing apparatus 1 according to the present embodiment, when an operation is interrupted in the middle, the currently displayed screen is stored as a pending screen, and the pending screen is displayed at the next start-up. If the operation has to be interrupted, the operation can be performed halfway.

  The information processing apparatus of the present invention has been described in detail with reference to the embodiment, but the present invention is not limited to the above-described embodiment.

  The operation patterns listed in the above-described embodiments are examples, and operation patterns other than those described above are also conceivable. In the embodiment, an example in which the operation of releasing the finger from the touch pad 10 is set as the “confirm” operation pattern. It is good. In this case, since the “confirmation” process can be performed without removing the finger from the touch pad 10, a plurality of actions from the first touch to the final confirmation can be performed with the finger touching the touch pad 10.

  In the above-described embodiment, an example in which the monitor 18 is used as the image output unit has been described. However, a head-up display may be used instead of the monitor 18. Since it is difficult to output a large amount of information due to the nature of the head-up display that is displayed on the windshield, when using a head-up display as an image output unit, for example, it is also possible to display a menu with icons and colors Good. As a result, the character information can be reduced, the driver's visual field can be sufficiently secured, and the display contents can be understood intuitively.

  In the above-described embodiment, the touch pad 10 is taken as an example of an input device, but the present invention is also applicable to input devices other than the touch pad 10. For example, it is possible to use a cross button or a joystick.

  According to the present invention, since the screen control is performed based on the operation pattern defined by the movement path of the input position, the operation can be performed without gazing at the operation unit or the screen. It is useful as an information processing device mounted on
