Research on the mathematical model of spatiotemporal dual-channel electrotactile tele-presence

In this paper, the principle and the model of spatiotemporal dual-channel electrotactile representation are described, and the relationship between tolerance limit and the stimulation current is also discussed. The analysis on spatiotemporal dual-channel model in electrotactile tele-presence shows that the whole tactile perception consists of two parts, one is the base volume of tactile perception, and another is the fluctuatuant amount. To obtain a comfortable electrotactile sensation, a limit to the fluctuauant amount is requested.
