1. An electronic device comprising:
- a memory for storing user input symbols;
a plurality of key input regions that display a subset of the user input symbols available in the memory;
motion detection circuitry configured to detect motion of the electronic device and generate an output signal corresponding to the detected motion; and
a processor coupled to the motion detection circuitry, the plurality of key input regions and the memory, wherein the processor processes the output signal of the motion detection circuitry and dynamically displays the subset of user input symbols on the plurality of key input regions based on the output signal of the motion detection circuitry.

Abstract
A system, method and computer program that utilizes motion detection circuitry to dynamically update displayed labels on one or more key input regions. In one aspect of the invention, the number of key input regions is substantially less than the number of keys on a conventional QWERTY keypad and the labels on the key input regions dynamically change based on the detected motion of the motion detection circuitry.
