Abstract
The invention discloses a motion measuring and animation feedback system based on smart shoes. The system comprises a motion measuring unit, a wireless transmission unit and a feedback unit; the wireless transmission unit is used for transmitting the data acquired by the motion measuring unit to the feedback unit. The system has the characteristics of being simple, practical and small in price; the cheap system is able to digitize the motion that focuses on the lower limbs and provide feedback for the body motion by an animation manner, so as to realize a big breakthrough of the human-computer interaction technology.
Description
Technical field
The present invention relates to a kind of system for Real-Time Monitoring motion state, be specifically related to a kind of Motion Technology measuring system based on intelligent shoe.The present invention can be applicable to the man-machine interaction of intelligent remote Motion Technology study (intelligent coach system) or motor play.
Background technology
Parameter in human motion is such as position of human center, speed, and cadence, stride, the estimation that the height of take-off all consumes Motion Technology assessment and energy is all extremely important, but the obtaining and being not easy of these parameters.Under laboratory condition, generally adopt many high-speed cameras to take sportsman, the 3 d space coordinate moving by computer synthesized human, calculates important parameter in conjunction with manikin.Obviously, ordinary people moves and can not under such condition, obtain kinematic parameter.The main way of measuring at present ordinary people's kinematic parameter is to measure step number, by estimating stride length, obtains the speed of motion, the parameters such as mileage, and error is larger.The another kind of mode of measuring running distance and speed is to use GPS location in recent years, but this method needs special GPS device, more expensive, and cannot be in indoor use.Except the mode of using multiple cameras to take, other modes can only obtain the simple parameter of motion, motion images that cannot Real-time Feedback sporter, and sporter cannot intuitively see the action of oneself.
Summary of the invention
The locus at each position in human motion is recorded and can be assessed Motion Technology, and calculating energy consumption, more can provide man-machine interaction animated feedback, is also long-range movement monitoring, the key of intelligent coach system.
But the laboratory equipment of existing Technology Need costliness could record the locus of human motion, the body gesture digitlization finishing man-machine interaction that ordinary movement person may be when not moving at ordinary times.The invention is intended to create one simple and easy, practicality, cheap, the system that error is less can complete the digitlization taking lower limb as main motion, and provides feedback by human action in the mode of animation, is a quantum jump of human-computer interaction technology.The technical solution adopted in the present invention is: a kind of motion measurement and animated feedback system based on intelligent shoe, comprise motion measurement unit, and wireless transmission unit and feedback unit, wireless transmission unit, the transfer of data that motion measurement unit is obtained is to feedback unit.
Described motion measurement unit is made up of a 3-axis acceleration sensor and multiple pressure sensor, by this cellular installation at sole, 3-axis acceleration sensor is measured the acceleration of three axles, by to integrated acceleration, can obtain sufficient speed, pressure sensor is used for measuring the Center of Pressure in vola; Described feedback unit will have the data of human motion original state, and the attitude of original state human body, namely has people's original state foot, knee, hip, shoulder, elbow, the position of hand.Experimenter's original state need to be consistent with the human motion original state in feedback unit.Record sufficient speed according to original state and moving cell, the track of sole pressure center, the parameters such as the time that foot supports are converted to the position at once of motion mesopodium, at once the position of center of gravity, again according to the position of center of gravity and track, roughly infer hip, at once the position of shoulder, the database of the relative position in each joint in the human motion of this action that unit obtains in 3 d human motion laboratory according to us at once, obtain the position at once of knee joint position and elbow joint and hand, complete human body real-time animation feedback is provided subsequently.
The useful technique effect that the present invention obtains is: the locus at each position in human motion is recorded and can be assessed Motion Technology, calculating energy consumes, man-machine interaction animated feedback more can be provided, simple and easy, practical, cheap system can complete the digitlization taking lower limb as main motion, and provides feedback by human action in the mode of animation, is a quantum jump of human-computer interaction technology.
