Feedback mechanism for user detection of reference location on a sensing device

摘要

Devices including an audio mechanism and a processing device coupled to display on-screen buttons on a touch-screen display are described. The processing device is configured to detect a conductive object proximate to the touch-screen display and to determine a position of the conductive object on the touch-screen display. The processing device is configured to provide different sounds via the audio mechanism for different ones of the on-screen buttons when the position of the conductive object is determined within the different on-screen buttons to allow detection of a reference location on the touch-screen display.
