Abstract: A computer system can include an input device having a housing defining an internal volume. The housing can include a grip portion and a base portion defining an aperture. The computer system can also include a tilt sensor disposed in the internal volume, a position sensor disposed at the aperture, and a processor. The processor can be electrically coupled to the position sensor, the tilt sensor, and a memory component storing electronic instructions that, when executed by the processor, cause the processor to receive a first input from the tilt sensor, receive a second input from the position sensor, determine, based on the first and second inputs, if the base is in contact with a support surface and an angle of the base relative to the support surface. The processor can also output a signal based on the angle if the base is in contact with the support surface.

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.
