Abstract:
1. A method for controlling a position of a control point on a command area comprising a graphical user interface including a number of user options for a device to be controlled, the method comprising acts of: aiming a pointing device comprising a camera in a direction of the command area, the aiming of the pointing device defining a real target point within a virtual control area, the virtual control area being centered around the real target point and at least partially including the command area; generating an image of the virtual control area aimed at by the pointing device; determining from the generated image of the virtual control area the position of the target point at which the pointing device is aimed and a distance from the pointing device to the virtual control area by selectively comparing only distinctive corner points in the generated virtual control area image and determining corresponding points in pre-defined, pre-stored templates of the command area or areas surrounding the command area; and calculating the control point position within the command area dependent upon the position of the real target point within the virtual control area, wherein the position of the control point in the virtual control area is at least at times different than the position of the target point in the virtual control area; wherein the dimensions and/or location of the virtual control area are defined according to momentary pointing conditions of the pointing device including the distance and angle between the pointing device and the command area and/or the control situation including a type and size of individual menu items in the command area wherein the dimensions of the virtual control area are extended in accordance with changes in distance between the pointing device and the command area.
