Patent attributes
Accordingly, a virtual keypad system for inputting text is provided. A virtual keypad system includes a remote controller having at least one touchpad incorporated therein and divided into a plurality of touch zones. A display device is in data communication with the remote controller and is operable to display a user interface including a keypad, where each key of the keypad is mapped to a touch zone of the touchpad. A prediction module, in response to an operator pressing a given touch zone to select a particular character, performs one or more key prediction methods to predict one or more next plausible keys. A key mapping module remaps the touch zones of the touchpad to the keys of the keypad based on the one or more next plausible keys.
