InfiniTouch: Rugged and Simple Touch Screens?
A new touch screen technology from QSI corporation called InfiniTouch looks like it could have real potential. Labeled as "force panel technology", it employs simple force sensors attached to the corners of any rigid surface. By calculating the force difference amongst the sensors the origin of the touch input can be determined, on both the X, Y and Z axis. There's a neat video demonstration showing the tech in action, including a touch sensitive panel with water running over it. Note: The site unfortunately requires Flash.
I just submitted this to Slashdot, but there's no telling if it will get posted... I figured that it can't hurt posting here as well.
