Abstract
Method and apparatus for providing tactile sensations. For one embodiment a first frequency at which to output a tactile sensation is received. A second frequency higher than the first frequency is determined. The second frequency is based on a frequency at which an inertial actuator outputs a second tactile sensation. A waveform having the first frequency and a waveform having the second frequency is combined to produce a signal configured to cause a composite tactile sensation at the second frequency, the composite tactile sensation conveying the first frequency.
