1. A method for remote controlling of mouse cursor functions of a computer device, the method comprising: tracking movement of a handheld pointing device in a three dimensional monitoring space based on a directional carrier sent by said handheld pointing device; modulating said directional carrier with a pulse pattern based on a corresponding manual operation action at said handheld pointing device; converting said tracked movement of said handheld pointing device in corresponding movement information; converting said movement information of said handheld pointing device in valid desktop coordinates for said computer device and moving a mouse cursor to these coordinates; demodulating said directional carrier and evaluating said pulse pattern in order to determine a corresponding manual operating action at said handheld pointing device; and taking corresponding action if a defined manual operating action at said handheld pointing device is determined.
