Abstract
In this study, focusing on "Body Image", which takes a part of controlling the precise motions of limbs, we developed the training device to improve the functions of Body Image of hemiplegic upper elbow. The training device contain the displaying function of computer graphics (CG) to present the model motion of flex of elbow and to feedback the error of elbow's angle between the angle of model and the user's angle of elbow simultaneously. As the result, it is clarified that the visual feedback function to display the dynamic behavior of error between the model image of CG and the user's real elbow cause the temporal development of the user's adaptive behavior to the device. The result suggests that biofeedback function realize the function for the rehabilitation of Body Image, and the function generate the mechanism to trigger the chain reaction to let the improvement of the Body Image improve itself. Also the training device containing the additional interactive function to control the model motion according to the user's motion realize the more efficient training with the enhancement of the mechanism of chain reaction.
