Tactile feedback method and apparatus

Abstract

A tactile feedback method and apparatus. The tactile feedback apparatus comprises a controller, a waveform processor, a piezoelectric driver and a touch panel, and the tactile feedback apparatus further comprises a virtual functional area; the controller comprises a waveform generator; the touch panel is configured to detect touch position information of user interactions, and output the touch position information to the controller; the controller is configured to determine whether the touch position information is in the virtual functional area, and if the touch position information is in the virtual functional area, control the waveform generator to generate an excitation signal and output same to the waveform processor; the waveform processor is configured to perform amplification processing on the excitation signal and output the processed signal to the piezoelectric driver; the piezoelectric driver is configured to receive the processed signal and deform, so as to drive the touch panel to vibrate.
