In just a couple hours on the show floor, I spotted great touch and pen input stuff, including this system from Korean company, ILS Communications, which stands for I Love School.
The system uses the standard micro-dot system to send pen input from paper to PC. I tried it on a standard sized pad, but my light touch, refined by years of digital inking, worked against me. Took a decent amount of pressure to get a stroke recognized, even if the ink shows up on the paper.
On a wallboard, it gets more impressive. Paired with a projector, not only does the PC capture the pen strokes, but what happens on the PC screen also happens on the board. This allows a user to change colors and tips without changing the pen. Short demo of this after the jump. There are more advanced systems that this, but they’re pushing this as a low-cost solution ideal for schools.
