Abstract
A tactile feedback method includes: determining a touch state; selecting a fitting waveform corresponding to the touch state according to the touch state; and providing an electrical signal to the tactile feedback apparatus according to the fitting waveform, so as to enable the tactile feedback apparatus to vibrate. A method for obtaining the fitting waveform includes: obtaining a touch simulation mechanical curve, and fitting the touch simulation mechanical curve to obtain the fitting waveform of the electrical signal to be provided to the tactile feedback apparatus.
