摘要:
An interface device providing haptic feedback to a user is in communication with a host computer. The device includes a housing, at least one sensor for detecting user input, and an actuator assembly. The actuator assembly includes a grounded flexure suspension coupled to an inertial mass which moves when the actuator assembly is energized to cause inertial sensations. The inertial mass includes a pole piece surrounding a magnet, and a grounded coil between magnet and pole piece causes the motion of the inertial mass when current is flowed therethrough. Another embodiment provides directional haptic feedback to a user and includes at least two actuator assemblies oriented such that the inertial masses oscillate substantially orthogonally, and can be controlled to output the inertial sensations approximately along a single axis having a desired orientation.
