The first interactive moviemap was produced at MIT in the late 1970s of Aspen, Colorado. A gyroscopic stabilizer with 16mm stop-frame cameras was mounted on top of a camera car and a fifth wheel with an encoder triggered the cameras every 10 feet. Filming took place daily between 10 AM and 2 PM to minimize lighting discrepancies. The camera car carefully drove down the center of the street for registered match-cuts. In addition to the basic "travel" footage, panoramic camera experiments, thousands of still frames, audio, and data were collected. The playback system required several laserdisc players, a computer, and a touch screen display. Very wide-angle lenses were used for filming, and some attempts at orthoscopic playback were made.
