Abstract

See full text

A user navigational apparatus. The user navigational apparatus includes a dial, a coding element, and an encoder. The coding element is coupled to a dial. The coding element includes a track of alternating reflective and non-reflective sections, each having a substantially oblique leading edge relative to a direction of movement of the coding element. The encoder includes an emitter and a detector. The emitter generates a light signal incident on the track of the coding element. The detector detects a reflected light signal which corresponds to a portion of the incident light signal that is reflected off of the reflective sections of the track. The detector also generates a channel signal corresponding to the reflected light signal.
