Abstract
Vibrotactile haptic feedback devices are disclosed. For example, in one embodiment, a device includes: a mass, an actuator configured to vibrate the mass, and a coupling disposed between the actuator and the mass or between the mass and a housing, the coupling having a first configuration with a compliance and a second configuration with a compliance, the compliance of the coupling in the first configuration being different from the compliance of the coupling in the second configuration, the actuator being configured to output haptic feedback associated with the first configuration of the coupling and haptic feedback associated with the second configuration of the coupling, the haptic feedback associated with the first configuration of the coupling being different from the haptic feedback associated with the second configuration of the coupling.
