Abstract
Directional haptic feedback provided in a haptic feedback interface device. An interface device includes at least two actuator assemblies, which each include a moving inertial mass. A single control signal provided to the actuator assemblies at different magnitudes provides directional inertial sensations felt by the user. A greater magnitude waveform can be applied to one actuator to provide a sensation having a direction approximately corresponding to a position of that actuator in the housing. In another embodiment, the actuator assemblies each include a rotary inertial mass and the control signals have different duty cycles to provide directional sensations. For power-consumption efficiency, the control signals can be interlaced or pulsed at a different frequency and duty cycle to reduce average power requirements.
