Projectors and projected area

Posted by keyvan on Ideas, Implementation, Reaction module, Hardware

We tried a new projector at the Science Park today, the Planar PR5020.

  • The projected area is not bigger than the Sharp's
  • It is brighter: 3000 lumens compared to Sharp's 1700
  • It costs us money to hire from lob: 400 SEK a day

Conclusion: We should stick with the Sharp if we can block out the natural light affecting the brightness of the projected display. If we can't, we will consider this projector again.

We also discussed the small size of the projected area. This isn't a problem for some applications (for example it might be fine with the prisoner's dilemma) but for others (for example the monster chasing game) we will need a bigger area. I looked into wide-angle lenses but couldn't find any for the projectors we have access to. I did find some more information on related work. What's most interesting is the number of PCs and projectors that are used to accomplish what we're trying to do:

  • The Famous Grouse Experiment (2002) uses 6 PCs and 6 projectors, 6 infrared spotlights and 2 cameras for tracking, and 8 shock sensors for footfall recognition! (They use a separate PC to control everything.)
  • Bodymover (2000) - no tech information on this one
