Abstract

The invention describes a method of controlling a position (x′, y′) of a control point (c) on a command area (ACM). This method comprises the steps of: —aiming a pointing device (1) comprising a camera (2) in the direction of the command area (ACM); —generating an image (I) of a target area (AI) aimed at by the pointing device; —processing the target area image (I) to determine a target point (T) at which the pointing device (1) is aimed; —determining position (x′, y′) of the control point (C) according to the position (x, y) of the target point (T) within a currently defined control area (ACT), which control area (Acr) includes at least partially the command area (ACM). Moreover the invention describes an adequate system and a pointing device (1) for controlling a control point position (P) on a command area (ACM).
