Pico Projectors

Firefly or Bright Future?

authored by: Raimund Dachselt, Jonna Häkkilä, Matt Jones, Markus Löchtefeld, Michael Rohs, Enrico Rukzio
Abstract: The emergence of various pico-projector technologies has resulted in the development of projector phones, camcorders with built-in projectors, and small accessory projectors that can be connected to other mobile devices. Pico projectors that use a laser as their light source have the advantage that the image is always in focus. The work of Cao, Forlines, and Balakrishnan and follow-up research has investigated multiple users interacting with each other using display torches. A wearable gestural interface augments the physical world around us with projected information. By means of an additional camera, hand gestures can be recognized on the augmented objects directly using computer-vision techniques. In currently available commercial mobile phones with pico projectors, there are no privacy mechanisms to prevent the public revelation of private information.
