Abstract
A haptic device having a plurality of operational modes, including a first operational mode and a second operational mode is provided. The first operational mode is associated with a frequency range. The second operational mode is associated with a frequency range that is different from the frequency range of the first operational mode. A controller is coupled to the haptic device, and is configured to send the haptic device a plurality of control schemes. Each control scheme is uniquely associated with an operational mode from the plurality of operational modes.Another embodiment provides a method that includes providing power to a haptic device configured to cause the haptic device to provide a haptic sensation above a pre-determined sensation threshold. A voltage pulse that is configured to change the haptic sensation output by the haptic device by a pre-determined amount within a pre-determined time period is also applied to the haptic device.
