Wow - Demo of stunning multi-touch intuitive screen

Hat tip to John Caswell.

Han is a research scientist for NYU's Courant Institute of Mathematical Sciences. Here, he demonstrates - for the first time publicly - his intuitive, "interface-free," touch-driven computer screen, which can be manipulated intuitively with the fingertips, and responds to varying levels of pressure

Here's the "demo, which drew spontaneous applause and audible gasps from the audience, begins with a simple lava lamp, then turns into a virtual photo-editing tabletop, where Han flicks photos across the screen as if they were paper snapshots" when the technology was first unveiled a year ago, from TED:



Here's another one via John about an amazing visualisation space with digital walls that become ceilings.



Found it interesting that the technology described as "a bit different from Powerpoint" actually ends in text based slides (for Nike apparently). According to John Sweller, a researcher from the University of New South Wales.

"It is effective to speak to a diagram, because it presents information in a different form. But it is not effective to speak the same words that are written, because it is putting too much load on the mind and decreases your ability to understand what is being presented."

"PowerPoint presentations can backfire if the information on the screen is the same as that which is verbalized because the audience's attention will be split between the two,"
