Video projectors are one of the most important tools for creators of interactive installations. The information for projectors is available on various websites, but this 2 part guide will focus on their use in production and interactive environments. Part 1 will focus on the projector as hardwarelenses, lumens, surfaces etc, and part 2 will go into more details on the software and calibration considerations. This will gather some of that disparate knowledge into the important bits you need to make informed decisions about creating a high quality experience.
Will want to give this resource a close read. I imagine it will be difficult to keep it up to date.
