The Future of Computing - Pen Based Pt 2

Handwriting recognition provides a power tool for accessing computers, but a more interesting an important development is the translation of the pen into a truly portable device. Used in conjunction with a data projector the pen can be physically located to write on any surface, not just a tablet or a whiteboard. With the image projected on a convenient surface the movement of the pen can be calibrated and mapped to the image to permit full computer use anywhere.
Check out the Portable Pen Computing video on the right. This shows a large projector sitting on its back projecting onto the table with the aid of a mirror. Cumbersome but they also show a small projector prototype as well.
However, the true synthesis comes when this pen technology gets married with the cellphone laser projector due to be release in 2008. For information on this tiny laser projector that is predicted to cost only tens of dollars! Have a look at the Miniature Data Projector video.
