But the full power of multi-touch expertise might be unleashed in screens far larger than those on rings. Over the past few years, Jeff Han, consulting research scientist at New York University, has developed an cheap way to make huge multi-touch screens accommodating ten, twenty, or even more fingers. He envisions applications ranging from interactive whiteboards to touch-screen tables & digital walls--any of which could be manipulated by over person. & this month, Han has unveiled Perceptive Pixel, his new company based on the expertise.
When Steve Jobs demonstrated Apple's new phone at Macworld recently, the feature that elicited the most "oohs" & "aahs" from the audience was the touch-screen interface: it allowed over touch at a time. This "multi-touch" expertise adds functions such as allowing a person to basically zoom in & out of pics & Web pages by pinching the screen with fingers.
"The new iPhone is small to be a fascinating multi-touch tool," says Han, who demonstrates his expertise on this YouTube video. That is because multi-touch expertise implies multiple users. Over person gathered around a huge touch screen "becomes fascinating," he says, "because multiple users can then become collaborators." Such collaboration could take plenty of forms, from brainstorming sessions using networked, interactive whiteboards to animation collaborations at which seven hands can mould the face of a monster. Perceptive Pixel is set to ship its first wall-size touch screen this month, to an undisclosed U.S. military customer.
Various approaches to multi-touch expertise have been demonstrated at engineering conferences since the 1980s. Mitsubishi Electric Research Labs developed the DiamondTouch table, which allows a group of people to sit around & collaborate on projects. Multi-touch screens "never went away, but they are coming back in different ways, & for definite things they will be important," says Bill Buxton, principal researcher at Microsoft Research.
