Abstract and Keywords

Abstract: In order to improve the multifunctionality of hand rehabilitation equipment and the diversity of rehabilitation programs and interaction methods, and to increase the fun of rehabilitation training, this paper designs a hand rehabilitation interactive system based on perceptual feedback. Based on the rehabilitation training device and signal acquisition, data processing and perceptual feedback modules, the system designs three rehabilitation games, namely Flying Bird and Table Tennis for training finger flexion and extension, and Gluttony Snake for training hand coordination. The active interactive training based on surface electromyographic signals and the active interactive training based on image gesture recognition are also proposed. The results of prototype experimental test show that the rehabilitation system has good stability, and the perceptual feedback can effectively enhance the interactive ability of the hand rehabilitation system and improve the rehabilitation effect of the patients. The results of the study can provide an effective interactive process of rehabilitation training for hand rehabilitation therapy.

Keywords: multimodal perceptual feedback; interactive system; surface electromyographic signals; hand rehabilitation; gamification

摘要和关键词

摘要: 为提高手部功能康复设备的多功能性、康复方案与交互方式的多样性,增加康复训练的趣味性,文章设计一款基于感知反馈的手部康复交互系统。该系统包含基于康复训练装置和信号采集、数据处理、感知反馈等模块设计的3款康复游戏(“飞翔的小鸟”和“乒乓球”游戏用于训练手指的屈伸能力,“贪吃蛇”游戏用于训练手部的协调能力),并具有基于表面肌电信号和基于图像手势识别的2种主动交互式训练方案。样机实验测试结果证明,康复系统具有良好的稳定性,感知反馈可以有效增强手部康复系统的交互能力,提升患者的康复效果。文章研究结果可为手部康复治疗提供一种有效的康复训练交互过程。
