Abstract

An optical touchpad system is disclosed that may be easily integrated into a variety of applications. One feature of the optical touchpad system that may contribute to this versatility may be the ability of the optical touchpad system to function in the same manner independent from a topology and/or opacity of an interface surface of the optical touchpad system. This may enable the interface surface to be composed of any of a variety of materials. This may further enable the interface surface to include various topologies adapted for the application in which the optical touchpad system may be employed.
