Logitech's Computer Pen
Logitech demonstrated a pen-and-paper combination that actually worked amazingly well:
Here's how it works:
- You pick the pen up from its little docking cradle.
- You write in the special notebook.
- You put the pen back in the cradle.
- The computer uploads the data from the pen, launches the notebook viewer and puts what you have written in the right spot and on the right page of the virtual notebook shown on the screen.
In other words, as long as you write in the special notebook with the special pen, then the virtual notebook on the screen will look exactly like the paper notebook that you wrote in. Every page will be identical.
The way they do it is by printing a faint array of very fine dots on each page of the notebook. The dots encode information that tells the pen where it is on the page as you write and which page you are writing on.
