Here is a video of something I put together not too long ago. It’s me using a laser pointer to control a mouse on my projector. I have a projector that I hooked up to my computer. I also hooked up a webcam and wrote some software that analyzes the camera image to pick out the bright red dot. Then I use it as an input device. It’s pretty simple, and works very well. I wrote a little paint program, and a dart game, and the game missile command, which makes a lot of sense in this kind of environment. Eventually I’ll put a few more games together try for multiple point recognition so I could do group activities and games with it.
