Abstract
Embodiments are disclosed herein that are related to computer mice configured to track motion on smooth surfaces. For example, one disclosed embodiment provides an optical mouse comprising a light source configured to illuminate a tracking surface, an image sensor, and an array of lenses configured to superimpose a plurality of images of spatially different areas of the tracking surface onto the image sensor. The optical mouse further comprises a controller configured to receive a plurality of time-sequenced frames of image data from the image sensor, to detect motion of the mouse on the tracking surface from movement of one or more tracking features in the plurality of time-sequenced frames of image data, and to output a motion signal.
