I posted a while back about Johnny Lee’s plans and software for converting a Wii Remote into a hand/motion tracker for various uses; seemed like a good match for some mapping applications. Touchless is another motion tracking system, this one using a webcam to track user-specified objects in the webcam view to modify objects on-screen.
Played with the software demo shown in the video above a bit (which includes manipulating a map image on-screen), and while it’s not perfect, it is kind of fun. It’s open source, and there’s an SDK available if you want to experiment with adding it to your own applications.
