Demo of Microsoft TouchWall
I don’t see how this is any different than the Microsoft Surface (the table), but as always, we all enjoy a little touch screen interaction, especially if it’s intuitive. Could be cool for presenting to huge groups.
Update: Ok, so it uses 3 lasers placed at the bottom that create a mesh across the screen which are monitored by a camera behind the screen. When you touch the screen it breaks the mesh and the software computes the interaction accordingly.
