Electrostatic force and vibration combined tactile representation method and device

Abstract

The invention relates to an electrostatic force and vibration combined tactile representation method and device and belongs to the field of human-computer interaction. The device comprises a finger positioning unit, a tactile processing unit, a tactile driving unit and a tactile presentation unit, wherein the finger positioning unit is used for obtaining the coordinate information of fingers; andthe tactile processing unit is used for extracting and rendering the visual information of a visual object to obtain the corresponding tactile driving signal parameters; the tactile driving unit is used for generating the corresponding driving signals according to the driving signal parameters; and the tactile presentation unit is used for changing the tangential force and the normal force on thefingers so as to realize a three-dimensional tactile representation effect. The device has the advantages that the tangential force and the normal force on the fingers are simultaneously changed in the process of plane interaction so as to present a more realistic three-dimensional tactile sensation; and the device is simple in structure, easy to realize and good in portability and can be integrated on various multimedia terminals.

Description

technical field [0001] The invention relates to a tactile reproduction device, which belongs to the field of virtual reality and human-computer interaction. Background technique [0002] Touch is one of the five sensory channels of human beings, which can realize two-way information interaction between human beings and the environment. In recent years, with the continuous development of human-computer interaction and virtual reality technology, the application of tactile reproduction technology enables users to open the tactile interaction channel on the basis of visual and auditory interaction, thus making the interaction process more realistic. immersion. Therefore, the sense of touch plays a very important role in human-computer interaction. [0003] At present, there are already some methods and devices for realizing tactile reproduction. [0004] Chinese patent "A wearable haptic interaction device with finger exoskeleton facing touch screen" (application number 2016...

AI Technical Summary

Problems solved by technology

[0008] The present invention provides a tactile reproduction method and device that integrates electrostatic force and vibration to solve the problem that array-based tactile reproduction devices and force tactile reproduction devices are complex in structure, poor in portability, and difficult to integrate on multimedia terminals. The electrostatic force tactile reproduction device can only provide changes in tangential force, and there is no tactile feedback when the finger is still, and the vibratory tactile reproduction device has problems such as single tactile sensation and poor authenticity.
