From the Ted Talk by Jinha Lee: Reach into the computer and grab a pixel

Unscramble the Blue Letters

Throughout the history of computers we've been striving to shorten the gap between us and digital information, the gap between our physical world and the world in the screen where our imagination can go wild. And this gap has become shorter, sohertr, and even shorter, and now this gap is shortened down to less than a millimeter, the thickness of a touch-screen glass, and the power of computing has become aelsiscbce to everyone. But I weerondd, what if there could be no boundary at all? I started to iimgane what this would look like. First, I created this tool which penetrates into the digital space, so when you press it hard on the screen, it transfers its physical body into pixels. deerinsgs can materialize their ideas directly in 3D, and surgeons can practice on virtual organs underneath the secren. So with this tool, this boundary has been broken. But our two hands still remain outside the screen. How can you reach inside and interact with the digital information using the full dexterity of our hadns? At Microsoft Applied Sciences, along with my mentor Cati Boulanger, I redesigned the computer and turned a little space above the keyboard into a digital workspace. By cbinonmig a tnnrerapsat display and dpeth cameras for sensing your fingers and face, now you can lift up your hands from the kobyraed and reach inside this 3D space and grab plxies with your bare hands. (Applause) Because windows and files have a position in the real space, selecting them is as easy as gibnbrag a book off your shelf. Then you can flip through this book while highlighting the lines, words on the virtual touch pad below each floating window. Architects can stretch or rotate the models with their two hands directly. So in these examples, we are reaching into the digital world. But how about rreisveng its role and having the digital iirnmtfoaon reach us instead? I'm sure many of us have had the eeeinpcrxe of buying and rennitrug items oninle. But now you don't have to wrroy about it. What I got here is an online augmented fitting room. This is a view that you get from head-mounted or see-through display when the system understands the geometry of your body. Taking this idea further, I started to think, instead of just seeing these pixels in our space, how can we make it physical so that we can tucoh and feel it? What would such a future look like? At MIT Media Lab, along with my advisor Hiroshi Ishii and my cotoloraalbr Rehmi Post, we creetad this one physical pxeil. Well, in this case, this spherical magnet acts like a 3D pixel in our space, which means that both cptruomes and people can move this object to anywhere within this little 3D space. What we did was eislntsleay canceling gravity and controlling the movement by combining magnetic levitation and mechanical actuation and sensing technologies. And by digitally proimnagmrg the object, we are liberating the oebjct from cntintroass of time and space, which means that now, haumn mnotios can be recorded and played back and left permanently in the physical world. So choreography can be taught physically over distance and Michael Jordan's fuamos shooting can be replicated over and over as a physical reality. Students can use this as a tool to learn about the cplomex concepts such as planetary motion, physics, and unlike computer screens or ttexoobks, this is a real, tangible experience that you can touch and feel, and it's very powerful. And what's more exciting than just turning what's currently in the computer phacyisl is to start imagining how programming the world will alter even our dliay physical activities. (Laughter) As you can see, the diatigl information will not just show us something but it will start directly aictng upon us as a part of our physical surroundings without disconnecting ourselves from our world. Today, we started by tlainkg about the boundary, but if we remove this bnrdaouy, the only boundary left is our imagination. Thank you. (alausppe)

Original Text

Throughout the history of computers we've been striving to shorten the gap between us and digital information, the gap between our physical world and the world in the screen where our imagination can go wild. And this gap has become shorter, shorter, and even shorter, and now this gap is shortened down to less than a millimeter, the thickness of a touch-screen glass, and the power of computing has become accessible to everyone. But I wondered, what if there could be no boundary at all? I started to imagine what this would look like. First, I created this tool which penetrates into the digital space, so when you press it hard on the screen, it transfers its physical body into pixels. Designers can materialize their ideas directly in 3D, and surgeons can practice on virtual organs underneath the screen. So with this tool, this boundary has been broken. But our two hands still remain outside the screen. How can you reach inside and interact with the digital information using the full dexterity of our hands? At Microsoft Applied Sciences, along with my mentor Cati Boulanger, I redesigned the computer and turned a little space above the keyboard into a digital workspace. By combining a transparent display and depth cameras for sensing your fingers and face, now you can lift up your hands from the keyboard and reach inside this 3D space and grab pixels with your bare hands. (Applause) Because windows and files have a position in the real space, selecting them is as easy as grabbing a book off your shelf. Then you can flip through this book while highlighting the lines, words on the virtual touch pad below each floating window. Architects can stretch or rotate the models with their two hands directly. So in these examples, we are reaching into the digital world. But how about reversing its role and having the digital information reach us instead? I'm sure many of us have had the experience of buying and returning items online. But now you don't have to worry about it. What I got here is an online augmented fitting room. This is a view that you get from head-mounted or see-through display when the system understands the geometry of your body. Taking this idea further, I started to think, instead of just seeing these pixels in our space, how can we make it physical so that we can touch and feel it? What would such a future look like? At MIT Media Lab, along with my advisor Hiroshi Ishii and my collaborator Rehmi Post, we created this one physical pixel. Well, in this case, this spherical magnet acts like a 3D pixel in our space, which means that both computers and people can move this object to anywhere within this little 3D space. What we did was essentially canceling gravity and controlling the movement by combining magnetic levitation and mechanical actuation and sensing technologies. And by digitally programming the object, we are liberating the object from constraints of time and space, which means that now, human motions can be recorded and played back and left permanently in the physical world. So choreography can be taught physically over distance and Michael Jordan's famous shooting can be replicated over and over as a physical reality. Students can use this as a tool to learn about the complex concepts such as planetary motion, physics, and unlike computer screens or textbooks, this is a real, tangible experience that you can touch and feel, and it's very powerful. And what's more exciting than just turning what's currently in the computer physical is to start imagining how programming the world will alter even our daily physical activities. (Laughter) As you can see, the digital information will not just show us something but it will start directly acting upon us as a part of our physical surroundings without disconnecting ourselves from our world. Today, we started by talking about the boundary, but if we remove this boundary, the only boundary left is our imagination. Thank you. (Applause)
