The great news is that big companies are working on Augmented Reality (AR).
The two biggest players are Apple, which is hardly surprising, and the car manufacturers BMW. Most people like the idea of having a car that projects things on their windscreen. It is something you would expect of a science-fiction movie, where a projection appears on a car windscreen that makes it look like something is on the other side of the glass.
The first and probably the best application would be for satellite navigation. It would be great to be able to look out through your screen and see arrows on the road where you have to go. Still, this sort of thing would be too dangerous at the moment because it would obscure the view of the driver. BMW are actually researching AR to help their engineers. Their cars are becoming more and more sophisticated, and it is making fixing and upgrading them even more difficult. Computers are used in a big way to help engineers find faults, and AR could make the process more efficient.
They could, in essence, see through cars and/or see annotated notes by looking at screens/devices that are pointed at cars in real time. Apple is working on this new technology for obvious reasons. Augmented reality is a new innovation that the Apple Company can apply to its mobile devices. It is yet another gimmick they can apply to their mobile devices to help regain ground they have lost to Samsung. Plus, over time, people may find productive uses for AR, which will then help Apple keep their market share.
