Abstract:
A system is provided that converts an input into one or more haptic effects using frequency shifting. The system receives an input signal. The system further performs a fast Fourier transform of the input signal. The system further shifts one or more frequencies of the transformed input signal to one or more frequencies within a shift-to frequency range. The system further performs an inverse fast Fourier transform of the frequency-shifted signal, where the inversely transformed signal forms a haptic signal. The system further generates the one or more haptic effects based on the haptic signal.
