Keyboard arrangement for a mobile communication device

摘要

The array of keys constituting a numeric phone keypad 13' on a mobile communication device only partially overlaps the array of keys that make up the text input keypad 11' creating an offset so that only subsets of the keys constituting the two keypads are common to both. Furthermore the spacebar 17' extends across all columns of a bottom row of the numeric keypad 13'. With this configuration, the numeric phone keypad can be more easily distinguished from the text input keypad while still having the benefits of having some shared keys.
