Electrostatic tactile representation in multimedia mobile terminal

Abstract

Electrostatic tactile representation technology can enhance the authenticity and immersion of human-computer interaction by perception of tactile features such as the shape and texture of visual objects in touch screen in naked finger. Focusing on the application in multimedia terminal of electrostatic force tactile representation technology, this paper summarizes the typical devices of electrostatic tactile representation, tactile rendering model-driven and data-driven algorithm, driving signal loading method, tactile representation effect evaluation method and so on. The author's view on the development status and future prospects of this technology is presented as follows: (1) Electrostatic tactile representation technology is an optimization scheme for implementing the low power and bare finger tactile representation function on the surface of the multimedia terminal; (2) The rendering dynamic range of electrostatic tactile representation technology is still insufficient, and the rendering effect of rough texture is better, but there is no effective algorithm for the rendering of fine texture. Multiple fusion technology may be one of the solutions; (3) From the perspective of evaluation of tactile representation effect, which shows that there is still considerable room for improvement both in theoretical models and applied algorithms; (4) Electrostatic tactile representation technology is essentially an applied science. Mutual promotion and benign promotion of theoretical research and commercial application is the only way for its progress. Therefore, a more mature prototype of principle is urgently needed to be popularized and applied in commerce.
