“Even though the technology has been around for decades, only now are we starting to see mass production and adoption of touchscreen and gestural devices for the public. Jeff Han’s influential 2006 TED demonstration of his multitouch system, followed by the launches of Nintendo’s Wii, Apple’s iPhone, and Microsoft Surface, have announced a new era of interaction design, one where gestures in space and touches on a screen will be as prominent as pointing and clicking.” (Dan Saffer – O’Reilly ETech 2008)
