Jeff Han: The radical promise of the multi-touch interface
Jeff Han - Human-computer interface designer
After years of research on touch-driven computer displays, Jeff Han has created a simple, multi-touch, multi-user screen interface that just might herald the end of the point-and-click era. Full bio
that's just ready to come out of the lab,
that you guys
the first to see it in person,
to really change
with machines from this point on.
with a multi-touch sensor.
or interactive whiteboards,
of contact at a time.
multiple points at the same time.
I can use chording actions;
all 10 fingers if I wanted to.
isn't completely new.
playing around with it in the '80s.
is actually high-resolution,
most importantly, very scalable.
here right now,
its newfound accessibility.
is what you can do with it
you can build on top of it.
a lava lamp application here.
of squeeze and put the blobs together.
with two of my fingers.
there's no instruction manual.
in our lab, Ilya Rosenberg, made.
comes out here.
sensor is that, you know,
with as many fingers here,
also inherently means multi-user.
with another part of Lava,
a new kind of sculpting tool,
making it malleable,
and solidifying in a certain state.
something like this in their lobby.
of a concrete example here,
to interact and move photos around.
is that if I have two fingers,
stretch it out like that really easily.
and rotate it effortlessly.
with both of my hands,
on each of my hands together.
the same thing -- stretch it out.
holding this down,
stretching this out.

like the $100 laptop,

is really the way
with machines from now on.
put that up there.
to make it work well for my hands.
there's no reason in this day and age
to a physical device.

to actually improving
from this point on.
the really wrong direction to go.
as we develop this kind of technology,

I can make these little fuzz balls.
that zooms in really quickly.
to switch to a hand tool
all at the same time.
and really quickly go back
and make even smaller things here.
like data visualization.
we all enjoyed Hans Rosling's talk,
I've been thinking about for a long time:
it's just sitting there.
and visualization and inference tools,
into this kind of data,
about the big picture here.
This is called WorldWind.

the same two-fingered gestures
to kind of go in --
what you'd expect, you know?
The interface just disappears.
are false-colored so you can --
about mapping applications --
you can do a gesture like this --
to tilt around like that --
to a kind of 2D panning and motion.
two fingers down --
and I can tilt up and down that way.
you can do with this interface.
playing around with it, too.
I want to show you is --
of a lot of entertainment apps
applications we can do with this.
I can draw out a curve.
it becomes a character.
is I can add control points.
with both of my fingers at the same time.
as I have to draw and make --
going on under here
and do the right thing.
a mesh here, with multiple control points,
of the kind of research I really love:
to make things do the right things,
to do exactly what you expect.
is a very active field right now in HCI.
a lot of other people are getting into it.
even more people get into it,
with all of you over the next few days
to your respective fields.

Why you should listen
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. His talent and reputation earned him a place on Time Magazine's 2008 list of the world's 100 Most Influential People.
