Abstract:
Text input may be entered on an electronic text input device by a user simultaneously contacting at least two of a plurality of discrete touch sensitive areas on a first surface of the device. A text character for input is determined, based on the touch sensitive areas which are detected as being simultaneously in contact with the user. The determined text character is locked by subsequent user action. A second surface of the device, such as that opposite the first surface, may include a display on which the determined text character and other information may be displayed.
