Abstract
The menu selection device uses a combination of the rotary position of a rotary optical encoder and the operation of a coaxially mounted push-button switch to enable the user to progress through various layers of a hierarchical menu system. The rotary position of the shaft translates to a menu category which is selected by the user activating the push-button switch. The selection of the menu category allows the user to then sequence through the plurality of menu entries within this menu category by again rotating the shaft. The user selects one of these menu entries by again activating the push-button switch.
