before building the prototypes for my project, I decided to work a little around the visualization of the eye tracking data in the physical space. I took a projector, tilted and keystoned a little. I have some ideas coming, but I am not sure how to wrap them up. Basically, having seen these line-graph-like visualizations on the floor, a person can hold a piece of what paper/cardboard (something that resembles a projector screen) on top of this curve, and start seeing the movie that the curve is related to. Moving the board forward/backward (or left or right, relatively) he can browse through the frames of the scene.
Some photos from my test is below.
