Abstract
A handheld pointer device provides radiation with a directional characteristic relative to its main axis. The radiation is detected by at least two detectors at different positions. This enables determining the orientation of the main axis as well as the displacement of the device along its main axis for 3D control of an object rendered on the screen of a display monitor.
Claims15
A data processing system (100) comprising:
- a handheld pointing device (102) for providing a radiation pattern with a directional characteristic (104) relative to a main axis (112) of the device;
- detection means (106, 108) for detecting the radiation;
- calculation means (111) connected to the detection means and operative to:
- determine an indication representative of a displacement of the pointing device along its main axis based on a first curve (114) of possible positions of the pointing device and a second curve (116) of possible other positions of the pointing device;
- and
- use the indication as user input for user control of the data processing.
