Abstract
In a computer system, a touch sensitive input device having touch sensitive auxiliary controls system can be used to anticipate a user's action. When a user's hand approaches a touch sensitive input device, feedback can be displayed on a display screen. A user can receive feedback without activating the input device. The feedback may take the form of status information related to the feature controlled by the input device and can vary depending upon the application open. Likewise, when the hand of a user is moved away from the touch sensitive input device, the feedback brought on by sensing the user's hand may disappear.
