Abstract: A force feedback wheel is provided on a mouse or other interface device manipulated by a user. A sensor detects a position of the mouse in a workspace and sends a position signal to a connected host computer indicating that position. A rotatable wheel is mounted upon the manipulandum and rotates about a wheel axis, where a wheel sensor provides a wheel signal to the host computer indicating a rotary position of the wheel. A wheel actuator coupled to the rotatable wheel applies a computer-modulated force to the wheel about the wheel axis. The mouse can be a standard mouse or a force-feedback mouse, where forces are applied in the mouse workspace. The host computer is preferably running a graphical environment, where the force applied to the wheel can correspond with an event or interaction displayed in the graphical environment. The wheel can also be included on other devices such as remote controls and radios.

Abstract: A device is disclosed that includes an interface member including a material and a manipulandum movable in a degree of freedom. The manipulandum is able to penetrate the material. A sensor is configured to output a position signal based on the position of the manipulandum. An actuator is configured to output haptic feedback by applying a compressive force to the material based on the position signal. In other embodiments, a method is disclosed that includes receiving a position signal associated with a position of a manipulandum, where at least a portion of the manipulandum penetrates the interface material. Haptic feedback is output by varying a density of the interface material based on the position signal.

Abstract: Method and apparatus for controlling magnitude and frequency of vibrotactile sensations for haptic feedback devices. A haptic feedback device, such as a gamepad controller, mouse, remote control, etc., includes a housing, an actuator coupled to the housing, and a mass. In some embodiments, the mass can be oscillated by the actuator and a coupling between the actuator and the mass or between the mass and the housing has a variable compliance. Varying the compliance allows vibrotactile sensations having different magnitudes for a given drive signal to be output. In other embodiments, the actuator is a rotary actuator and the mass is an eccentric mass rotatable by the actuator about an axis of rotation. The eccentric mass has an eccentricity that can be varied relative to the axis of rotation while the mass is rotating. Varying the eccentricity allows vibrotactile sensations having different magnitudes for a given drive signal.

Abstract: An interface device and method providing haptic sensations to a user. A user physically contacts a housing of the interface device, and a sensor device detects the manipulation of the interface device by the user. An actuator assembly includes an actuator that provides output forces to the user as haptic sensations.
