  • Inner-sensor pointing device system
    Patent number: 11023053
    Abstract: Aspects discussed herein are directed to ergonomic pointing device systems. In one example, a pointing device system includes an elongate base member, a sleeve disposed to fit over at least a portion of the elongate base member, the sleeve configured to rotate about the elongate base member in a first direction and slide about the elongate base member in a second direction substantially orthogonal to the first direction, where the sleeve includes a pattern on a surface thereof, and a sensor disposed within the elongate base member and positioned to detect at least one of a rotational movement of the sleeve relative to the sensor and an axial movement of the sleeve relative to the sensor based at least in part on a variation of the pattern within a field of view of the sensor.
