Title: (EN) Method of controlling a control point position on a command area and method for control of a device
Abstract: front page image
(EN)

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).
