Abstract
Architecture for managing clutch height in an optical navigational device such as a computer mouse. In one embodiment for a mouse, a feature can be molded into the bottom case that limits the clutch height by occluding the reflected light to the image sensor when the device is lifted from the tracking surface. Tracking is disabled when the clutch height threshold is exceeded, and re-enabled when the device is brought under the distance clutch height threshold. The device includes firmware controlled algorithm adjustments to one or more correlation parameters. User interfaces may also be employed to implement various aspects of the embodiments discussed herein.
