Samsung started off its case today by going straight at the heart of Apple's utility patents, showing off two software systems with similar functionality that pre-date iOS altogether. Adam Bogue, president of Circle 12, showed off images and video of a projection-based touchscreen surface called the DiamondTouch Table. Developed in 2001 at the Mitsubishi Electronic Research Laboratory (MERL), the DiamondTouch featured two particularly-relevant pieces of software: Fractal Zoom, an application that allowed users to manipulate images using multiple fingers, and Tablecloth.
The latter allows users to pull an image down in a window, revealing a duplicate image right above it; letting go causes the image to snap back to its original position, providing a visual effect that appeared quite similar to Apple's bounce-back effect. The DiamondTouch was easily accessible in the MERL lobby for anyone to access, leaving open the possibility that anyone in Cupertino could have seen the device — in fact, Bogue revealed that he'd even given a demonstration to Apple itself in 2003.
