Structured Light in Sunlight
ICCV '13: Proceedings of the 2013 IEEE International Conference on Computer VisionPages 545–552https://doi.org/10.1109/ICCV.2013.73Strong ambient illumination severely degrades the performance of structured light based techniques. This is especially true in outdoor scenarios, where the structured light sources have to compete with sunlight, whose power is often 2-5 orders of ...

LightBeam: nomadic pico projector interaction with real world objects
CHI EA '12: CHI '12 Extended Abstracts on Human Factors in Computing SystemsPages 2513–2518https://doi.org/10.1145/2212776.2223828Pico projectors have lately been investigated as mobile display and interaction devices. We propose to use them as 'light beams': Everyday objects sojourning in a beam are turned into dedicated projection surfaces and tangible interaction devices. While ...
