The central idea is that by enhancing stereo depth perception for users of these rides, their experience will be significantly intensified at very low additional cost.
Mobile phones now commonly incorporate cameraphones. Two such devices may be mounted on a spectacle frame with lenses positioned so as to roughly double the normal interocular distance. This has the effect of providing an intensified, 3-D view and a correspondingly heightened experience for thrillseeking ride customers.
The spectacle frames might be made available in different or customisable colours, for example. Obviously a similar system might be designed using only prisms, but the use of mobile phones adds value to a purchase which has already been made and makes further use of universally loved and trusted technology. People will, we believe, regard this reuse as ‘cool.’
It may even be possible for a wearer to record their 3-D visual experience for playback (with sound) once the ride is over (assuming synchronisation can be achieved during replay).
Sunglasses manufacturers such as Oakley have already begun to develop all sorts of oddly-shaped, wrap-around glasses embodying electronics.
