We did some preliminary prototyping with different kinds of materials and different angles, brightnesses and phones.
The important facts are these:
>>brightness DOES matter, too high sometimes contrasts out, while too low doesn't always read
>>a direct parallel to the camera is essential for the best read and reaction time
>>the fiducial does not read on all brightness levels when colored (it was pink)
>>the fiducial seems to work on both iphone and android on all brightness levels when black
>>how well the fiducial reads is directly tied to how fast the reaction is
>>the reaction seems to lag about a half of a second at it's highest read
>>the camera will have to be mounted under the plexi, all in a self-contained space
So I measured the windows and these are the dimensions. We really want to use vellum as it rear-projects nicely and looks the most professional when mounted on the glass.

Will was very excited.
