Abstract:
An optical navigation device for use with mobile telephones and the like is disclosed, which has a reduced height as compared with current designs. The navigation device comprises a laser such as a VCSEL laser, an exposed user surface and two other surfaces that provide for total internal reflection of the incident laser beam. The surfaces are constructed with shallower than normal angles, preserving the basic functionality of the device while reducing the height.
