Kinect's Grandaddy Running On an Apple IIe In 1978
An anonymous reader writes "30 years before words like performance capture, augmented reality, or avatars were around — let alone commonplace — experimental film and video artist Tom DeWitt created a system that features aspects of all of them. Pantomation let users interact in real-time with a digital environment and props. It was built using Apple IIe's, analog video gear, and lots of custom hacking and patching. He's currently working on a holographic 3D system that's similarly ahead of its time."
Still, it's impressive that he was doing this on a IIe 5 years before they were released.
