Abstract
A system and method for entering data on a portable device includes determining a tilt state (tilt sensor) as a button (keypad) is being pressed. The determined tilt state can be used to disambiguate from among a plurality of characters associated with the pressed button. In a preferred embodiment, the portable device is a mobile phone and the button is part of a standard 12-button keypad.
