Abstract (en)
[origin: WO2006040200A1] The invention relates to a device and a method for light guidance in an augmented-reality system, whereby a recorder unit (AE), with an optical axis, records a real object (RO, RS) and displays the same on a display unit (I). A data processing unit generates a virtual object (VO) and also displays the same on the display unit (I). Based on a known sensor positioning, a sensor alignment, a sensor directional diagram and a provided sensor output signal from at least two light-sensitive sensors (S), an illumination angle is then determined and the light guidance for the virtual object (VO) carried out in the display unit (I), based on said illumination angle.
