Unveiling the genius of multi-touch interface design

Jeff Han shows off a cheap, scalable multi-touch and pressure-sensitive computer screen interface that may spell the end of point-and-click.



Jeff Han’s intuitive "interface-free" computer displays -- controlled by the touch of fingertips -- will change forever the way you think about computers. At TED 2006, the audience whistled, clapped and gasped audibly as Han demoed (for the first time publicly) his prototype drafting table-cum-touch display, developed at NYU's Courant Institute of Mathematical Sciences. The demo included a virtual lightbox, where he moved photos by fingertip -- as if they were paper on a desk -- flicking them across the screen and zooming in and out by pinching two fingers together, as well as a Google Earth-like map that he tilted and flew over with simple moves.

When the demo hit the web, bloggers and YouTubers made him a bit of a megastar. (His video has been watched more than 600,000 times on YouTube alone; "Amazing," "Incredible" and "Freaking awesome" are the typical responses there. Also: "When can I buy one?") After this legendary demo, Han launched a startup called Perceptive Pixel -- and when he came back to TED2007, he and his team brought an entire interactive wall, where TEDsters lined up to play virtual guitars.

BumpTop Desktop Is A Beautiful Mess

Anand Agarawala presents BumpTop, a user interface that takes the usual desktop metaphor to a glorious, 3-D extreme, transforming file navigation into a freewheeling playground of crumpled documents and clipping-covered “walls.”



Interface designer, software developer, inventor, and nerdcore hip-hopper Anand Agarawala brings a welcome sense of expressiveness to the dusty desktop interface. His BumpTop software applies a 3D metaphor and rough-and-tumble interactivity that delights anyone who sees it in action.

In addition to its raw play-with-me fun , BumpTop is also an inspiring example of unconventional thinking. The BumpTop world is a physical space, where traditional point-and-click movement is replaced with a more literal "push and pull" approach, and the icons each possess a weight that reflects their relative importance. Meanwhile, commands are executed via a novel set of pen/stylus shortcuts that go well beyond the limited click-and-drag way of doing things.

Even if you're not quite ready to trade your olde tyme desktop for the BumpTop experience, the interface's unexpected approach to problem-solving is sure to bump-start your thinking in new and unusual directions.

Look! Up in the sky! It's Virtual Earth!

Microsoft's Stephen Lawler gives a whirlwind tour of Virtual Earth, moving up, down and through its hyper-real cityscapes with dazzlingly fluidity, a remarkable feat that requires staggering amounts of data to bring into focus.




Microsoft's Stephen Lawler offers a tour of Virtual Earth that not only reveals the power and potential of the software itself, but also gives a global glimpse of the new virtual frontier of digital globes, the 3D Web and the metaverse.

Lawler also explores the enormous effort it takes to create the fluid blending and shifting between the multiple views and resolutions of Virtual Earth. From the satellites and airplanes that gather photo data for a top-down view to the ground vehicles and headgear-wearing pedestrians who canvas the ground for an eye-level perspective -- all of it represents a monumental effort of logistics and mechanics.

Siegfried Woldhek: The true face of Leonardo Da Vinci?

Mona Lisa is one of the best-known faces on the planet. But would you recognize an image of Leonardo da Vinci? Illustrator Siegfried Woldhek uses some thoughtful image-analysis techniques to find what he believes is the true face of Leonardo.




Siegfried Woldhek knows faces -- he's drawn more than 1,100 of them. Using sophisticated image analysis and his own skills as an artist, he's come up with a fascinating discovery about Leonardo Da Vinci.


Why you should listen to him:

The work of illustrator Siegfried Woldhek is a familiar sight in the European press. His witty pen and sharp eye for faces helps him capture political and literary figures in his home country, the Netherlands, and around the world (he estimates he's drawn 1,100 faces). He's also an accomplished illustrator of nature, and was the longtime CEO of the Dutch branch of the World Wildlife Fund.

Woldhek is the founder of nabuur.com, "the global neighbor network." On nabuur.com, villages in developing communities can connect with volunteers and resources online throughout the world -- sort of a Match.com that pairs communities with the people who'd like to get involved.
