Elias said the communication power of their system is �thousands of times greater� than that of a mouse, which uses just a single moving point as the main input. Using this new technology, two human hands provide 10 points of contact, with a wide range of motion for each, thus providing thousands of different patterns, each of which can mean something different to the computer.

While much about the computer has changed over the last three decades�greater power, faster speeds, more memory�what has not changed is the user interface.
