Basically, as you entered the park you were handed Yourday Velcro wristbands which had chips in them. These chips were read by radio beacons around the park in certain areas. Most of which are actually still in the same place they were when it first tried to launch.
As you walked down Towers Street for example, your band was read by some readers next to the trees near the coke kiosk, this then activated the camera on top on towers trading that recorded you. At the end of the day, you took your band back to the Your Day office and your footage was assembled.
Air is a prime example of a ride in motion, as your leave the station and enter the tunnel, the readers are on the floor and this then activated cameras on the lift hill!
It was a fantastic idea and truly a great shame it did not work.
