Abstract: A method (62) for providing visual feedback to a user having a hand (14) and operating a graphical user interface (28) on a display (24) using an input device (10). The input device (10) includes an image sensor (46) and an input element (40) defining an input surface (42), the input element (40) being at least partially transparent. The method (62) includes: with the hand (14) substantially adjacent to the input element (40), acquiring a hand image of the hand (14) through the input element (40) using the image sensor (46); identifying predetermined anatomical features (13) in the hand image and associate with each a corresponding feature location indicative of a position of the predetermined anatomical features (13) relative to the input surface (40); and displaying cursors (34, 61) in a window (30) of the graphical user interface (28) at positions relative to the window (30) that correspond to the feature locations relative to the input surface (40).

Abstract: An x-y user input device, such as a pen tablet or digitizing tablet, used to control a cursor on a display of a data processing system, comprises an imaging device or camera and an image processor for displaying a captured image of a user's hand operating the input device within a window of the display. The input device is generally operated using a pointing device that controls the cursor position on the display while being synchronously imaged and displayed with the user's hand on the display. The position of the captured image of the user's hand and pointing device in the window relative to the cursor corresponds to a position of the hand relative to the pointing device, thereby providing a visualization effect that increases user comfort and proficiency with the input device.
