It’s working! This is a quick, down and dirty video of the prototype. Most of our early problems came from our pen, but these were quickly resolved. After that, it was relatively easy to calibrate and it worked equally well on a whiteboard and on a light colored wall.
In the video I mistakenly mention that the pen’s button acts like the right mouse button, but it’s actually the left. Imagine interacting with any and all of your computer applications this way. There are some really interesting possibilities out there. I’m looking forward to experimenting with this using Word, Hot Potatoes web-based activities, and more. Do you have other ideas? Leave me a comment.
