This is a cheap, scalable multi-touch and pressure-sensitive computer screen interface that may spell the end of point-and-click. 

The future use of multi-touch technology is expected to rapidly become common place. For example, touch screen telephones are expected to increase from 200,000 shipped in 2006, to 21 million in 2012.

While Touch sensing is commonplace for single points of contact, Multi-Touch systems enables a user to interact with a system with more than one finger at a time, allowing for the use of both hands along with chording gestures. These kinds of interactions hold tremendous potential for advances in efficiency, usability, and intuitiveness. Multi-Touch systems are inherently also able to accommodate multiple users simultaneously, which is especially useful for collaborative scenarios such as interactive walls and tabletops.
