Abstract
A device may obtain a provided haptic waveform. A device may convert the provided haptic waveform with a Fourier transform to create a converted haptic waveform. A device may identify at least one frequency peak of the converted haptic waveform. A device may drive an eccentric rotating mass (ERM) haptic device at least partially according to the at least one frequency peak.

A method of providing haptic feedback to a user, the method comprising:
- obtaining a provided haptic waveform;
- converting the provided haptic waveform with a Fourier transform to create a converted haptic waveform;
- identifying at least one frequency peak of the converted haptic waveform;
- and
- driving an eccentric rotating mass (ERM) haptic device at least partially according to the at least one frequency peak.
A method of providing haptic feedback to a user, the method comprising:
- at an electronic device:
- obtaining a provided haptic waveform;
- converting the provided haptic waveform with a Fourier transform to create a converted haptic waveform;
- identifying at least one frequency peak of the converted haptic waveform;
- and
- transmitting a haptic command to an accessory device based at least partially on the converted haptic waveform.
