The invention describes a pointing device (1) and a methode for item locationand/or selection assistance, which method comprises visually presenting anumber of items (M1, M2, M3, M4) in a visual presentation (VIP, VP'), aiminga pointing device (1) comprising a camera (2) and a directable source (12) of aconcentrated beam of light (L) at the visual presentation (VP, VP') of theitems (M1, M2, M3, M4), generating image data (3) of a target area (A) at which thepointing device (1) is aimed, analysing the image data (3) in order to locate aspecific point within the target area (A), generating control signals (9) forcontrolling the directing arrangement (4), and directing the concentratedbeam of light (L) so that the point (Pl) coincides with the specific point in thetarget area (A). The invention describes an interacting device (13) for interactingwith a pointing device (1) to carry out I:he method for item location and/or selectionassistance. Furthermore, the invention describes a system (14) for item locationand/or selection assistance. |
