Abstract

An actuator configured to provide haptic feedback to a user. The actuator is located on a plate and is configured to apply various excitations to the plate to generate a mechanical wave propagating in the controlled direction. The excitations can be a translational motion of the actuator (or a portion of the actuator) in two or three perpendicular axes. Alternatively, the excitations can be a non-translational motion (e.g., rotation about an axis) of the actuator (or a portion of the actuator). By generating the mechanical wave traveling in the controlled direction, loss of energy due to scattering of the mechanical wave can be obviated.
