<p>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).</p> |
