康复认知评估系统中基于体感交互技术的手势识别方法

摘要

In the current field of medical treatment and healing, the somatosensory interaction technology is widely applied in the patient's family personalized training and rehabilitation evaluation. By the combination of vir-tual simulation and somatosensory technology evaluation system, we need to accurately identify patients gestural to acquire patients gestural with the information of speed, distance and angle in the movement. And on this basis, de-signed for the patients with different levels of training mode to help patients recover soon and return to society. In this article according to the theory of somatosensory interaction technology’s gesture recognition method carried on the thorough research. Use DTW arithmetic(Dynamic Time Warping)to achieve gesture recognition task.%在当前康复医疗领域中，体感交互技术广泛应用于患者的家庭个性化训练和康复评估中。由虚拟仿真与体感技术相结合的康复评估系统中，需要对患者的手势动作进行准确的识别，获取患者手势运动中的速度、距离和角度等信息。并以此为基础，为患者设计不同层次的训练模式，以帮助患者的早日康复和重返社会。本文针对体感交互技术中的手势识别方法进行了深入的研究，使用DTW（Dynamic Time Warping，动态时间规整）算法来完成手势识别任务。
