PORTABLE COMMUNICATION DEVICE HAVING A TOUCH-SENSITIVE INPUT DEVICE WITH NON-LINEAR ACTIVE AREAS

摘要

A portable communication device includes a touch-sensitive input device that is configured to include a substantially V-shaped active area. The portable communication device is configured to facilitate character selection and navigation by sensing the user's thumb position on and movement along the substantially V-shaped active area. The portable communication device is configured to provide keypad functionality via the touch-sensitive input device without a graphical representation of character keys and/or navigation keys represented on the touch-sensitive input device.
