Hanwah Japan launched a digital pen, the Duo for Laptop.
You can write directly on your laptop’s screen to convert your average notebook in a table PC!
You’ll have to put a receiver on the top of your screen that captures your movements through infrared and ultrasonic technology. The drawback is it’s only compatible with 15.4-Inch LCD screens.
