Abstract
A method improves data entry in keypads, and a keypad system incorporates the method. To allow miniaturisation of handsets below the limit where accurate character selection could otherwise be assured, the method applies keys which are in fact multiple position switches. Each key on a keypad can be operated between any of three positions. Placing the key in an “up” position corresponds to a “default” or “cancel previous key press” action. Placing the key in the “intermediate” position corresponds to a user presentation mode whereby the display shows a group of possible data entry options. Placing the key in the “down” position corresponds to a selection mode whereby the display shows that a tentative data entry has been accepted by the user.
