Reach into the computer and grab a pixel
-
0:00 - 0:04Throughout the history of computers
-
0:04 - 0:07we've been striving
to shorten the gap between us -
0:07 - 0:08and digital information,
-
0:08 - 0:10the gap between our physical world
-
0:10 - 0:12and the world in the screen
-
0:12 - 0:15where our imagination can go wild.
-
0:15 - 0:19And this gap has become shorter,
-
0:19 - 0:22shorter, and even shorter,
-
0:22 - 0:23and now this gap is shortened down
-
0:23 - 0:25to less than a millimeter,
-
0:25 - 0:26the thickness of a touch-screen glass,
-
0:26 - 0:28and the power of computing
-
0:28 - 0:33has become accessible to everyone.
-
0:33 - 0:38But I wondered, what if there
could be no boundary at all? -
0:38 - 0:42I started to imagine
what this would look like. -
0:42 - 0:44First, I created this tool
-
0:44 - 0:46which penetrates into the digital space,
-
0:47 - 0:49so when you press it hard on the screen,
-
0:49 - 0:52it transfers its physical
body into pixels. -
0:52 - 0:54Designers can materialize their ideas
-
0:54 - 0:56directly in 3D,
-
0:56 - 0:58and surgeons can practice
on virtual organs -
0:58 - 1:00underneath the screen.
-
1:01 - 1:05So with this tool, this
boundary has been broken. -
1:05 - 1:08But our two hands still
remain outside the screen. -
1:08 - 1:11How can you reach inside and interact
-
1:11 - 1:12with the digital information
-
1:12 - 1:15using the full dexterity of our hands?
-
1:15 - 1:18At Microsoft Applied Sciences,
-
1:18 - 1:19along with my mentor Cati Boulanger,
-
1:20 - 1:21I redesigned the computer
-
1:21 - 1:24and turned a little space
above the keyboard -
1:24 - 1:26into a digital workspace.
-
1:26 - 1:29By combining a transparent
display and depth cameras -
1:29 - 1:30for sensing your fingers and face,
-
1:30 - 1:32now you can lift up your hands
from the keyboard -
1:32 - 1:35and reach inside this 3D space
-
1:35 - 1:38and grab pixels with your bare hands.
-
1:38 - 1:41(Applause)
-
1:41 - 1:45Because windows and files have
a position in the real space, -
1:45 - 1:48selecting them is as easy
as grabbing a book off your shelf. -
1:48 - 1:51Then you can flip through this book
-
1:51 - 1:52while highlighting the lines, words
-
1:52 - 1:55on the virtual touch pad
below each floating window. -
1:55 - 1:57Architects can stretch
or rotate the models -
1:57 - 2:00with their two hands directly.
-
2:00 - 2:01So in these examples,
-
2:01 - 2:04we are reaching into the digital world.
-
2:04 - 2:06But how about reversing its role
-
2:06 - 2:11and having the digital
information reach us instead? -
2:11 - 2:13I'm sure many of us
have had the experience -
2:13 - 2:15of buying and returning items online.
-
2:15 - 2:17But now you don't have to worry about it.
-
2:17 - 2:22What I got here is an online
augmented fitting room. -
2:22 - 2:24This is a view that you get from
-
2:24 - 2:26head-mounted or see-through display
-
2:26 - 2:31when the system understands
the geometry of your body. -
2:31 - 2:34Taking this idea further,
I started to think, -
2:34 - 2:38instead of just seeing
these pixels in our space, -
2:38 - 2:39how can we make it physical
-
2:39 - 2:44so that we can touch and feel it?
-
2:44 - 2:47What would such a future look like?
-
2:47 - 2:50At MIT Media Lab,
along with my advisor Hiroshi Ishii -
2:50 - 2:52and my collaborator Rehmi Post,
-
2:52 - 2:56we created this one physical pixel.
-
2:56 - 2:59Well, in this case, this spherical magnet
-
2:59 - 3:01acts like a 3D pixel in our space,
-
3:01 - 3:04which means that both computers and people
-
3:04 - 3:06can move this object to anywhere
-
3:06 - 3:08within this little 3D space.
-
3:08 - 3:11What we did was essentially
canceling gravity -
3:11 - 3:13and controlling the movement by combining
-
3:13 - 3:16magnetic levitation
and mechanical actuation -
3:16 - 3:19and sensing technologies.
-
3:19 - 3:21And by digitally programming the object,
-
3:21 - 3:24we are liberating
the object from constraints -
3:24 - 3:27of time and space, which means that now,
-
3:27 - 3:31human motions can be
recorded and played back -
3:31 - 3:35and left permanently
in the physical world. -
3:35 - 3:38So choreography can be taught
physically over distance -
3:38 - 3:40and Michael Jordan's famous
shooting can be replicated -
3:40 - 3:44over and over as a physical reality.
-
3:44 - 3:46Students can use this as a tool
-
3:46 - 3:48to learn about the complex concepts
-
3:48 - 3:52such as planetary motion, physics,
-
3:52 - 3:55and unlike computer screens or textbooks,
-
3:55 - 3:57this is a real, tangible experience
-
3:57 - 4:01that you can touch and feel,
and it's very powerful. -
4:01 - 4:03And what's more exciting
-
4:03 - 4:06than just turning what's currently
in the computer physical -
4:06 - 4:10is to start imagining
how programming the world -
4:10 - 4:13will alter even our daily
physical activities. -
4:15 - 4:18(Laughter)
-
4:18 - 4:21As you can see, the digital information
-
4:21 - 4:22will not just show us something
-
4:22 - 4:24but it will start directly acting upon us
-
4:24 - 4:27as a part of our physical surroundings
-
4:27 - 4:31without disconnecting
ourselves from our world. -
4:31 - 4:35Today, we started by talking
about the boundary, -
4:35 - 4:38but if we remove this boundary,
-
4:38 - 4:42the only boundary left is our imagination.
-
4:42 - 4:43Thank you.
-
4:43 - 4:48(Applause)
- Title:
- Reach into the computer and grab a pixel
- Speaker:
- Jinha Lee
- Description:
-
The border between our physical world and the digital information surrounding us has been getting thinner and thinner. Designer and engineer Jinha Lee wants to dissolve it altogether. As he demonstrates in this short, gasp-inducing talk, his ideas include a pen that penetrates into a screen to draw 3D models and a computer desktop prototype that lets you reach through the screen to manipulate digital objects.
