Abstract

The invention describes a method of controlling a position (x′, y′) of a control point (c) on a command area (A CM ). This method comprises the steps of:
aiming a pointing device ( 1 ) comprising a camera ( 2 ) in the direction of the command area (A CM ); generating an image (I) of a target area (A I ) 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 (A CT ), which control area (A cr ) includes at least partially the command area (A CM ).

Moreover the invention describes an adequate system and a pointing device ( 1 ) for controlling a control point position (P) on a command area (A CM ).

First claim

The invention claimed is:

1. A system for controlling a position of a control point in a command area, the system comprising:
a graphical user interface including the command area indicating a user option;
a pointing device comprising a camera for aiming in a direction of the command area to generate an image of a virtual control area;
an image processing unit for processing the image for determining the position of a target point at which the pointing device is aimed dependin…
