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 hardware(lenses, 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.
Choosing the right type of camera for your interactive installation is one of the most important technical choices you can make in your initial planning phases. Making the incorrect choice can really impact how well your installation reacts to its victims and it can also impact its ability to perform robustly in a large amount of environments.
