I have spent some time the last two days playing around with webcam games. These are games that, if you have a webcam, you can play by moving. You control objects on the screen with your image. Amazing! My first thought is that this interface could be used to overcome 1st grader problems reaching the smartboard. Second, I thought this might offer some way of many students interacting with the projection at the same time. Third, and most obviously, this technology has immediate and definite uses in Physical Education. I wonder if there is an easy way to create these kinds of games and programs. It would be nice to be able to make interactive learning games and simulations that make use of interactive webcam technology.
