Abstract
The invention describes a method for controlling a display, which method comprises the steps of displaying a portion of a visual presentation (VP) on the display (4) and aiming a pointing device (1) comprising a camera (2) at a target area (A) to indicate a target (PT) in the visual presentation (VP), whereby the target (PT) may be inside or outside of a portion (14) of the visual presentation (VP) currently visible on the display (4). An image (3) of the target area (A) aimed at by the pointing device (1) is generated and interpreted to determine the location of the target (PT) within the visual presentation (VP). The visual presentation (VP) is adjusted as necessary to display that portion of the visual presentation (VP) which encompasses the target (PT). The invention also describes a pointing device (1), a display control interface (8, 8′, 8″) and a system comprising such a pointing device (1) and display control interface (8, 8′, 8″) suitable for applying this method.
