A computer-implemented method includes receiving first and second movement data corresponding to a movement of a first and second computer mouse, respectively, wherein the first and second computer mice are oriented in a same direction are moving in unison over a same trajectory while the first and second movement data is contemporaneously received; determining a movement distance for the first and second computer mice based on the first and second movement data, respectively; determining a performance characteristic for the first computer mouse based on the determined first movement distance; determining the performance characteristic for the second computer mouse based on the determined second movement distance; determining a difference in the performance characteristic for the first computer mouse with respect to the second computer mouse; and calibrating the performance characteristic of the second computer mouse to match the performance characteristic of the first computer mouse.

Input device configuration cloning

A method of operating an input device can include generating a light beam by a light source module, steering the light beam towards a target location on an underlying surface, steering a reflected light beam towards an image sensor of the input device, receiving the reflected light beam by the image sensor, and generating tracking data by the image sensor that corresponds to a two-dimensional (2D) movement of the input device on the underlying surface. The method further includes determining that the input device is operating: on and in contact with the underlying surface when the reflected light beam received by the image sensor is located on a first set of pixels of the image sensor, and above and not in contact with the underlying surface when the reflected light beam is located on a second set of pixels of the plurality of pixels of the image sensor.

Working range and lift detection in an input device

A method of operating a computer mouse includes receiving electromagnetic (EM) radiation emitted from a source external to the computer mouse, the received EM radiation induces noise within one or more bands of noise frequencies and an image sensor circuit of the computer mouse generates erroneous movement detection signals in response to an operating frequency of the image sensor circuit being within the one or more bands of noise frequencies. The method further includes determining the operating frequency of the image sensor circuit, comparing the operating frequency to a target frequency, wherein the target frequency is outside of the one or more bands of noise frequencies, and tuning the operating frequency of the image sensor circuit towards the target frequency.
