Abstract
A wireless telephone unit of the present invention has an improved shuttle for more ergonomically and efficiently entering input to the telephone unit. The shuttle, acting as a rotary encoder, controls the scrolling of material across a display of the wireless telephone unit. The shuttle is located on the face of the wireless telephone unit so as to be operated by the thumb of a user without regard to whether the telephone unit is held in the right or left hand of the user. The shuttle further comprises a detent mechanism such that increments of rotation of the shuttle passed the detent mechanism are perceptible to the user and are correlated to an amount of material scrolled across the display. The shuttle is also displacable along its access of rotation to input parameter information to the wireless telephone unit. The telephone unit's keypad may be hidden in the unit when not in use.
