Abstract: A computer input system includes a mouse including a housing having an interior surface defining an internal volume and a sensor assembly disposed in the internal volume. A processor is electrically coupled to the sensor assembly and a memory component having electronic instructions stored thereon that, when executed by the processor, causes the processor to determine an orientation of the mouse relative to a hand based on a touch input from the hand detected by the sensor assembly. The mouse can also have a circular array of touch sensors or lights that detect hand position and provide orientation information to the user.

Abstract: A three-dimensional control system includes an input device, a computing device, and a tracking assembly. The input device can include an input sensor, an inertial measurement unit sensor, and an ultrasonic speaker. The tracking assembly can include a plurality of ultrasonic microphones and an inertial measurement unit disposed on or with the computing device. The plurality of ultrasonic microphones can include three microphones in a first plane and at least one other ultrasonic microphone disposed out of the first plane. The ultrasonic microphones can be configured to detect ultrasonic waves output by the speaker of the input device and the computing device can triangulate the position of the input device relative to the computing device in space.

Abstract: An input device, such as a mouse, can include a housing defining an exterior grip portion and an internal volume, a sensor assembly disposed in the internal volume, and an emitter electrically coupled to the sensor assembly. In response to the sensor assembly detecting a first touch input on the housing, the emitter sends a first signal including information regarding an angular position of the grip portion. In response to the sensor assembly detecting a second touch input on the housing, the emitter sends a second signal including information regarding a direction of a force exerted on the housing from the second touch input.

Abstract: An input device can include a housing defining an internal volume and a lower portion, the lower portion defining an aperture, an input sensor disposed in the internal volume, and a haptic assembly disposed in the internal volume. The haptic assembly can include an actuator and a foot coupled to the actuator and aligned with the aperture. The actuator can be configured to selectively extend the foot through the aperture to vary a sliding resistance of the input device on a support surface.

Abstract: The disclosed apparatus provides a base supporting at one end an upstanding mast pivotally mounting a boom in the upper portion of the mast to extend over the base. A bench to support a user is supported by the base spacedly thereabove and below the boom. A handle assembly is pivotally carried by the boom end extending over the base to depend spacedly above the base. A hydraulic cylinder communicates between the boom and the base to resist pivotal motion of the boom responsive to exercise motion of the handle assembly by a user supported on the bench. A resistance assembly provides spaced grips carried by a pull shaft for longitudinal motion toward and away from the bench end distal from the mast. The pull shaft end proximate the mast communicates by cable supported on pulleys to the boom end distal from the handle assembly so that the boom resists motion of the resistance assembly grips responsive to exercise motion thereof by a user supported on the bench.

Abstract: An upright mechanical arm is pivoted to a freestanding base for grasping by a player to simulate an arm-wrestling contest. The arm is power-driven in a given direction by a hydraulic jack. The force applied by the jack is adjustable. Switches detect grasping of the mechanical arm by the player and positioning of the player's elbow on an elbow pad. Such switches are interconnected with control of the hydraulic jack to cut off the supply of hydraulic liquid automatically. Bells and buzzers can be provided to indicate when the game has been "won" or "lost" by the player.
