Abstract
A computing device may determine a haptic effect to be produced by a haptic device of the computing device. The computing device may select, based at least in part on the haptic effect, a modulation frequency. The computing device may determine a combination of a carrier frequency and the modulation frequency to produce the haptic effect. The computing device may drive the haptic device according to the combination of the carrier frequency and the modulation frequency to output a vibration pattern associated with the haptic effect.

A method comprising:
- determining, by one or more processors of a computing device, a haptic effect to be produced by a haptic device of the computing device;
- selecting, by the one or more processors and based at least in part on the haptic effect, a modulation frequency;
- determining, by the one or more processors, a combination of a carrier frequency and the modulation frequency to produce the haptic effect;
- and
- driving, by the one or more processors, the haptic device according to the combination of the carrier frequency and the modulation frequency to output a vibration pattern associated with the haptic effect.
A computing device comprising:
- a haptic device;
- a memory;
- and
- one or more processors configured to:
- determine a haptic effect to be produced by the haptic device;
- select, based at least in part on the haptic effect, a modulation frequency;
- determine a combination of a carrier frequency and the modulation frequency to produce the haptic effect;
- and
- drive the haptic device according to the combination of the carrier frequency and the modulation frequency to output a vibration pattern associated with the haptic effect.
A non-transitory computer-readable storage medium storing instructions that, when executed, cause one or more processors of a computing device to:
- determine a haptic effect to be produced by a haptic device of the computing device;
- select, based at least in part on the haptic effect, a modulation frequency;
- determine a combination of a carrier frequency and the modulation frequency to produce the haptic effect;
