Abstract
A keyboard may include a plurality of optical keys. Each optical key may include an optical module and an interaction surface. The optical key may be configured to be activated based on movement of an object on or adjacent the interaction surface. Each movement may produce a different output from the optical module to thereby generate a predetermined input for a device.
