发明名称 Sound to haptic effect conversion system using waveform
摘要 A haptic conversion system is provided that intercepts frames of audio data, such as a digital audio signal, converts the frames into a haptic signal, and plays the created haptic signal through an actuator to produce haptic effects. The haptic signal is based on a maximum value of each audio data frame, which defines a magnitude of the haptic signal. The haptic signal is applied to the actuator configured to receive the haptic signal, where the actuator utilizes the haptic signal to generate the one or more haptic effects.

主权项 1. A computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to convert an audio signal into one or more haptic effects, the converting comprising: receiving a data frame of the audio signal; generating a maximum amplitude value of the data frame; transforming the data frame; generating at least one sine carrier waveform that is scaled according to a maximum amplitude value of the transformed data frame; mixing the transformed data frame with the at least one sine carrier waveform to generate a modulated data frame; generating a haptic signal based on the maximum amplitude value of the data frame and the modulated data frame, wherein the maximum amplitude value of the data frame determines whether the haptic signal is generated; and sending the haptic signal to an actuator to generate the one or more haptic effects.
