Abstract
A haptic device configured to provide haptic feedback to a user. In one aspect, a user or part of a user is located on the haptic device including actuators and damping elements. A haptic feedback wave is generated by an actuator and propagated to the user or part of the user on the haptic device. Damping elements receive the haptic feedback wave and suppress the haptic feedback wave to reduce a reflection thereof.
Claims20
A haptic mat comprising:
- a center plate;
- an actuator coupled to the center plate, the actuator configured to generate a haptic feedback wave directed towards a center of the center plate;
- and
- a periphery section that circumscribes the center plate, the periphery section coupled to a damping element, the damping element configured to receive the haptic feedback wave exiting the center plate and further configured to suppress the haptic feedback wave to reduce reflections of the haptic feedback wave from the periphery section toward the center of the center plate, the damping element comprising a magnetic element configured to suppress the haptic feedback wave.
