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.
