Abstract

The invention provides a hand-stretching grabbing kinematics coordination test analysis system with a separable visual supervision functiona. The system comprises a mirror surface system, a three-dimensional reflective mark point system, a motion capture system and an analysis system. When the arm performs a hand-stretching grabbing motion on the shading side of the mirror surface, the visual line of a subject can observe a virtual target object under the refraction action of the mirror surface, but the real-time poses of the grasping arm and the fingers cannot be observed due to the shielding of the mirror surface. By means of the mirror surface system, stripping of visual supervision in the hand stretching and grasping process is achieved. Meanwhile, the perceptual motion function of the subject is evaluated by accurately recording kinematics parameter information of the fingers. The system has important application value in neurophysiology test, nervous system development evaluation, hand function test, quantitative evaluation of perceived motion functions of various neuromuscular lesions and the like.

Description

technical field [0001] The disclosure belongs to the technical field of coordination test and analysis, and in particular relates to a reach and grasp kinematics coordination test and analysis system with separable visual supervision. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Reaching and grabbing objects is one of the most common and important behaviors in everyday life. This seemingly simple action is the result of a combination of complex sensorimotor control mechanisms. Central nervous system decision-making plays a central role in action control and information processing, so the functional state of the central nervous system can be glimpsed through the investigation of the kinematic coordination of reaching and grasping. [0004] In the motion control of reaching and grasping, vision plays a key role in the observation and j...
