Abstract
Products and processes for providing haptic feedback in a user interface are disclosed. One exemplary embodiment of an apparatus comprises a first element comprising a first surface, a second element comprising a second surface, and an actuator configured vary a force between the first and second surfaces. In one embodiment, the second element may be configured to be displaced relative to first element in a degree of freedom. In another embodiment, at least one of the first surface and the second surface may comprise a thermoplastic polymer.
