A three-dimensional space body position sense testing device and method

Abstract

The invention discloses a three-dimensional space body position sense testing device. The test device includes: a slide bar, a slide block, a displacement sensor, a joystick, a potentiometer, an elastic strap, and a controller; the slide block is provided with a groove, the slide bar is clamped in the groove, and the slide block moves The rod moves; the displacement sensor is arranged on the slider, and the displacement sensor is used to detect the displacement of the slider; the joystick is coaxially connected with the slider; the potentiometer is arranged on the joystick, and the potentiometer is used to detect the Describe the swing angle of the joystick; the controller is connected with the potentiometer and the displacement sensor respectively, and the controller determines the spatial coordinates of the slider according to the displacement of the slider and the swing angle of the joystick; the elastic strap is bound to the slider, and the elastic Straps are used to secure the human test position. The invention determines the space coordinates of the slide block through the displacement of the slide block and the swing angle of the joystick, and then can accurately determine the space position coordinates of the position of the human body.

Description

technical field [0001] The invention relates to the field of position sense testing, in particular to a three-dimensional body position sense testing device and method. Background technique [0002] The infrared motion capture system can obtain data such as the joint angle of the subject, but the operation is complicated and requires a long-term trained professional to operate. And because there is no special proprioceptive position sense test function, and there is no visual feedback on the test joint angle during positioning, it is difficult for the subjects to ensure the accuracy of positioning. The collected data also needs to be manually recorded and calculated and analyzed, which increases the error of human operation. [0003] At present, the position sense of the human body is mostly concentrated on a single plane or a single axis. Therefore, the obtained test results are only part of the information about the proprioceptive position sense of the upper limbs, and ca...

Problems solved by technology

[0003] At present, the position sense of the human body is mostly concentrated on a single plane or a single axis. Therefore, the obtained test results are only part of the information about the proprioceptive position sense of the upper limbs, and cannot fully detect the position sense of the human body, making the detection results inaccurate. precise
