  • Device and Method for Light and Shade Simulation in an Augmented-Reality System
    Publication number: 20080211813
    Abstract: A device and a method guide light in an augmented-reality system, whereby a recorder unit, with an optical axis, records a real object and displays the same on a display unit. A data processing unit generates a virtual object and also displays the same on the display unit. 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, an illumination angle is then determined and the light guidance for the virtual object carried out in the display unit, based on said illumination angle.
