英文摘要: Natural and harmonious interactions between human beings and virtual objects are the focus of research on man-machine interface. Hand gesture interactions have become the core supportive technology for many applications. To fulfill the requirements for delicate exercise training in the exercise rehabilitation of human hands, this project conducts theoretical and method research on hand gesture interactions based on visual and haptic perception. This project proposes to study the haptic perception mechanism and dynamic characteristics of human hands in the natural environment through experimentation and analysis of the physiologic factors of the sense of touch. Meanwhile, the study enhances the accuracy of hand gesture identification by incorporating visual information. Considering the security and cost required by exercise rehabilitation systems, this project maps the virtual sense of touch into real visual space through augmented reality technology, and proposes a rapid calibration device and algorithm for haptic measurements. Finally, we integrate the research results in stages, and design an exercise rehabilitation system for human hands to simulate natural interaction, thereby evaluating and verifying the effect. Starting from the universality of the method, this project illustrates the substantial differenc
