A shopping trolley (or basket) which contains a fold-out step and allows small people to reach stuff they can’t get to on supermarket shelves (I’m constantly being asked by people to get them a packet of high-altitude cornflakes).
This would enable more stock to be accessible and make better use of expensive floor space. It might also allow extra pricing differentials/incentives: “Reach up for lower prices.”
If insurance companies stymie this, because they won’t allow shoppers to take on the dangerous task of climbing a step, then maybe some kind of vertical ‘magazine’ can be arranged, whereby products are fed in at the top and customers extract them at the bottom, automatically making available the next item. This would have the added advantage that products could be delivered to the shop in such feeder tubes…and the tubes themselves could announce to the stock control system when a tube was empty. In addition, the current danger of getting a glass jar of mayonnaise on the head would be eliminated.
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.
Imagine clothing that is multilayered. As you move, adjacent layers rub against each other and the friction results in a self heating effect.
The extra energy required to move about whilst wearing this kit could make it useful for eg training in cold conditions.
