Method for providing feedback responsive to sensing a physical presence proximate to a control of an electronic device

摘要

In a computer system, a touch sensitive input device having touch sensitive auxiliary controls can be used to provide a user with information regarding the functionality of an auxiliary control. 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 by touching or being extremely proximate to an auxiliary control. The feedback may take the form of a tool tip related to the auxiliary control or a combination of auxiliary controls simultaneously touched. 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.
