At the University of Tokyo, the Naemura Group is developing paper computing technology, which can automatically erase, copy and print hand-drawn sketches on paper.
The paper is coated with a photochromic material, which changes color when it absorbs light, and a DMD-driven UV projector with a resolution of 1024 x 768 pixels is used to print the image onto the paper.
"The idea is to do computing on paper. But in the future, we'd like to enable several people to create one document, like with Google Docs, actually using real-world paper while far apart. We'd also like to enhance the rendering that's possible through collaboration between people and computers. For example, by giving more detailed access than you get by hand, and enabling you to draw large areas at once."

I'm technically clueless. What's the difference between drawing on paper (in this technology) and drawing on a tablet?
As well as using a camera and computer, this system uses a laser and UV light, . . .

Dear Raelsatu,
Thanks for your reply, I told you I'm not technologically literate. If I understand it correctly,
So, to use the paper technology you need a computer, paper, a camera, a laser, a UV light and projector, and special ink.
To use the tablet, you need . . . a tablet?
With respect,
