AI Technical Summary
Technical Problem
Existing haptic feedback devices are usually single-function, and it is difficult for touch and body sensation to form an intrinsic physical coupling, resulting in insufficient realism and immersion in the interaction.
Method used
The tactile sensation (skin pressure) and body sensation (joint torque) are mechanically coupled together by a flexible connector. The tension of the flexible connector is naturally changed by the user's joint movements, so as to achieve synchronous and coordinated feedback of tactile sensation and body sensation.
Benefits of technology
It enhances the realism and immersion of haptic feedback, simplifies the system structure, reduces energy consumption and cost, and can simulate a variety of real-world physical phenomena.

Abstract
The invention relates to the technical field of man-machine interaction, and provides a tactile display device fusing tactile sense and somatosensory display, a tactile sense display unit in the tactile display device fusing tactile sense and somatosensory display is suitable for fitting local skin of a user body, and is used for generating pressure feedback on the skin according to an input signal; the somatosensory display unit is suitable for being fixed to two sides of a joint of a user body and is used for generating torque feedback at the joint; the flexible connecting piece penetrates through the somatosensory display unit and is connected to the touch display unit; when the joints of the body of the user move, the tension of the flexible connecting piece is changed, the tension change is transmitted to the touch display unit through the flexible connecting piece to generate local pressure, and meanwhile corresponding torque feedback is generated at the joints. The touch sense and the somatosensory are mechanically coupled together through one flexible connecting piece, so that generation of the two senses is highly synchronous in time and strength, and the sense of reality and immersion of tactile feedback are enhanced.
