Title:
METHOD AND DEVICE FOR DESIGNING HAPTIC EFFECT, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/000635
Kind Code:
A1
Abstract:
A method and device for designing a haptic effect, and a computer-readable storage medium. The method comprises: obtaining an acceleration waveform and a signal sampling rate of a vibration system (S100); and performing integral optimization processing on the acceleration waveform according to the acceleration waveform and the signal sampling rate so as to obtain an optimized displacement waveform (S200); and calculating equalized voltage according to the optimized displacement waveform so as to play back the haptic effect according to the equalized voltage (S300). By means of the method above, the problem of drift generated when the acceleration quadratic integral is displaced can be removed, and the vibration of the vibration system at a time outside of the acceleration waveform is avoided.
