Cursor actuation with fingerprint recognition
First Claim
1. A method comprising:
- receiving a user input at a touch-sensitive user interface;
responsive to the receiving, automatically recognizing a user from biometric data gathered at the touch-sensitive user interface;
responsive to recognizing;
automatically activating a visual cursor at a graphical display;
sensing movement of the user input across the touch-sensitive user interface and moving the visual cursor across the graphical display in correspondence with the sensed planar movement; and
automatically removing the visual cursor from the graphical display when a user input is no longer sensed at the touch-sensitive user interface.

Abstract
A method for controlling a graphical display receives a user input at a touch-sensitive user interface. Responsive to receiving that user input, a user is automatically recognized from biometric data gathered at that touch-sensitive user interface, such as by comparison to a locally stored database of authorized users. A visual cursor at a graphical display is then automatically activated. The visual cursor is removed from the graphical display when the user input is no longer received at the touch-sensitive user interface. So long as the visual cursor is not removed and after user authentication, movement of the visual cursor at the graphical display is made to correspond with movement sensed at the touch-sensitive user interface.

9. A program of machine-readable instructions, tangibly embodied on an information bearing medium and executable by a digital data processor, to perform actions directed toward actuating a cursor in correspondence with a user input, the actions comprising:
-
determining that a user initiates contact with a touch sensitive interface; gathering user biometric data from the touch-sensitive interface; determining from the biometric data whether the user is authorized; only if the user is authorized, then; activating a visual cursor at a graphical display interface; sensing movement at the touch-sensitive interface and moving the visual cursor in correspondence therewith; continuously or periodically determining whether the user remains in contact with the touch-sensitive interface; and removing the visual cursor from the graphical display interface when it is determined that the user no longer remains in contact with the touch-sensitive interface. - View Dependent Claims (10, 11, 12, 13)

14. A device comprising:
-
a touch-sensitive user interface adapted to gather user biometric data; a graphical display screen; a computer readable medium on which is stored user biometric data; and a processor coupled to the touch-sensitive user interface, the graphical display screen, and the computer readable medium, said processor for; comparing user biometric data gathered at the touch-sensitive user interface to the stored user biometric data; initiating display of a cursor at the graphical display screen if the comparing is positive; determining continuously or periodically that an authorized user remains in contact with the touch-sensitive user interface, and disabling the display of the cursor at the graphical display screen when it is determined that the user no longer remains in contact with the touch-sensitive user interface. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. An apparatus comprising:
-
means for receiving a user input at a user interface; means, responsive to receiving for recognizing a user from biometric data gathered at the user input; means, responsive to recognizing for activating a visual cursor at a graphical display; means for sensing a planar movement of the user input at the user interface and moving the visual cursor across the graphical display in correspondence with the sensed planar movement; and means for removing the visual cursor from the graphical display when the user input is no longer sensed at the user interface. - View Dependent Claims (22)
