Sensors around the periphery of the remote control unit detect contact with the user's hand. A trained model-based pattern classification system analyzes the periphery sensor data and makes a probabilistic prediction of the user's hand size. The hand size is then used to control a mapping system that defines how gestures by the user's thumb upon a touchpad of the remote control unit are mapped to the control region upon a separate display screen.
