World's largest touchscreen
People impressed by the screen real estate offered by the Apple iPad need to check out the Reality Touch Theatre, described as the world's biggest touchscreen interface.
Unveiled in February the touchscreen, based at the University of Groningen in Holland, is based on a cylindrical 3D theatre that has been upgraded to be able to process more than 100 touches at any one time.
