I Introduction
Human computer interaction technology, that is, the interaction mode between human and robot, is an important part of modern computer science. It involves a wide range of subject knowledge, and the technical system is very complex. It plays an important role in the interaction between users and robots. Human computer interaction technology is also widely used in various fields, such as human-computer interaction technology [1]. In the rehabilitation training of cerebral palsy, language training and action training are two important parts. After the emergence of human-computer interaction technology, its powerful language recognition function and action recognition function provide a new idea for the rehabilitation training of cerebral palsy. To improve the technical level of cerebral palsy rehabilitation training system through human-computer interaction technology related to voice and action, combined with the assistance of rehabilitation robot, provides a new idea for cerebral palsy rehabilitation training [2]. Based on the speech recognition and action recognition technology of human-computer interaction, a robot assisted rehabilitation training system for cerebral palsy is designed. Through the intelligent assistance of the training process, the burden of the rehabilitation teacher is reduced, the whole rehabilitation process is simplified, and the patients are motivated to participate in the training actively in an interactive way, so as to enhance the ability of communication and object recognition, and improve the limb function, hand and eye function Coordination and cognitive level, improve their quality of life [3].
