In order to address the problem of traditional dolphin adjuvant therapy such as high cost and its limitation in time and place, this paper introduces a three-dimensional virtual dolphin adjuvant therapy system based on virtual reality technology. By adopting Oculus wearable three-dimensional display, the system combined natural human-computer interaction based on Leap Motion with high-precision gesture recognition and cognitive training, and achieved immersive three-dimensional interactive game for child rehabilitation training purposes. The experimental data showed that the system can effectively improve the cognitive and social abilities of those children with autism spectrum disorder, providing a useful exploration for the rehabilitation of those children.
针对传统海豚辅助疗法成本高、且受时间和场地限制等缺陷，本文设计了一种基于虚拟现实技术的三维虚拟海豚辅助治疗系统。该系统借助可穿戴三维显示器 Oculus，并将基于高精度手势识别设备 Leap Motion 的自然人机交互手段与认知训练相结合，以达到在沉浸式三维交互游戏中进行儿童康复训练的目的。实验数据表明，该系统可有效提高孤独症谱系障碍儿童的认知与社交能力，这为游戏化的孤独症谱系障碍儿童辅助康复提供了有益探索。.
