News: Cell phone screen projector
A new type of projector for mobile devices has been developed recently, which could allow manufacturers to integrate a tiny projector in a cell phone or any mobile device, and display an image outside of the device, on a screen, desk or other surface. Add a projected keyboard and you really have a virtual computer in front of you.
The problem of small screen and keyboard are the main two factors that all the advances in mobile technologies have yet to solve. Now with projected screens, it still is not a perfect solution, since you need to have a flat surface nearby to project onto, but it's an interesting experiment. Now all we need is an integrated hologram to get full 3D images and we're talking!
