Vibrating Substrate for Haptic Interface
A haptic device is provided having a substrate with a touch surface and one or more actuators for vibrating the substrate in a multiplicity of higher resonant modes, each of which has a high enough frequency to be inaudible and high enough amplitude to create a friction reduction effect at a plurality of vibrating regions on the substrate touch surface.
