Design and Research of Multimodal Fusion Feedback Device Based on Virtual Interactive System

This paper proposes a kinesthetic-tactile fusion feedback system based on virtual interaction. Combining the results of human fingertip deformation characteristics analysis and an upper limb motion mechanism, a fingertip tactile feedback device and an arm kinesthetic feedback device are designed and analyzed for blind instructors. In order to verify the effectiveness of the method, virtual touch experiments are established through the mapping relationship between the master-slave and virtual end. The results showed that the average recognition rate of virtual objects is 79.58%, and the recognition speed is improved by 41.9% compared with the one without force feedback, indicating that the kinesthetic-tactile feedback device can provide more haptic perception information in virtual feedback and improve the recognition rate of haptic perception.
