Abstract

A haptic effect generation system includes a computing platform including a hardware processor, an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), and a memory storing a haptic software code, as well as a haptic transformer coupled to the computing platform. The haptic transformer receives an input signal, and transforms the input signal to a first audio signal corresponding to the input signal. The ADC converts the first audio signal to a first audio data. The hardware processor executes the haptic software code to receive the first audio data from the ADC, and to generate a second audio data using the first audio data, the second audio data corresponding to a desired haptic effect. The DAC converts the second audio data to a second audio signal. The haptic transformer then transforms the second audio signal to a haptic actuator signal for producing the desired haptic effect.
