Abstract:
An apparatus and method for providing an active feedback of a position of a conductive object, manipulated by a user on a sensing device, to allow detection of a reference location on the sensing device by the user. The apparatus may include a sensing device to detect a presence of a conductive object, manipulated by a user on the sensing device, a processing device coupled to the sensing device, the processing device to determine a position of the conductive object on the sensing device, and a feedback mechanism coupled to the processing device to provide an active feedback to the user to allow detection of a reference location on the sensing device by the user.
