First Shareable Interactive Display 161

Jeremy Newton writes "I want to share with you a new device that allows multiple moving images to be displayed to several users from the same screen at the same time. The project is called a "Shift in Time," my thesis project for NYU's Interactive Telecommunications Program. The driving goal of this project was to end fighting over the remote control, the gamepad, or the keyboard. It also makes room for new applications in marketing, games, and education. Recently it's gotten some buzz on Engadget.com."

    • You could use this [atcsd.com] to make an array of "Beams" pointing to the corresponding area you want different channels of sound to be heard. It works by using ultrasonic sound (which is much more directional) to create interference (the signal we want) in a given area. Interesting technology.

    I wonder if you could do some sort of trick where you had polarised screens, and people wore corresponding glasses, so that you could have two separate images appearing on the screen, but only visible to people with the right glasses?

    Or, use the Imax like glasses, and flick between images on the screen every refresh, and have the glasses blackout for every other image, so you again only see the images you want.

    Oh, and to top it off, you set up your speakers really carefully so that there's interference, and a node (no sound) from one source for person A, and a node from the other source for person B!

    Then again, it's probably easier just to use two screens and two headphones :)

      since this lens would be very cheap to produce, it might be interesting to see a lens packaged with a video game to allow head-to-head play on the same TV without traditional split-screen. (the TV would need to be high-definition to achieve any sort of usable resolution, and the game could present an interface to calibrate the image interlacing granularity and alignment so that the lens could be used on different sized displays.)
      The second practical use is a stereoscopic display without the need for red/blue, polarized, or shutter glasses. I think there is already a company that produces these, at some ungodly price...

I mean, everyone has their own workstation now a-days, but last time I checked, most people will crowd around one large television in a living room. And last time I checked, families like to argue on what to watch.

      I think this would also be great for collaborative code writing. One person sits on one side, writing the code, while the other person looks at the spec/API. Need to check some? Just tilt your head to the other side.

Like head to head gaming on the same display.. No split-screen means you can only see your enemy from your point of view, not his as well. Currently, you can get this by putting two displays back-to-back but that's usually not convenient for space, so his idea looks good here.

      Relax. If you RTFS you will see this is for "NYU's Interactive Telecommunications Program", not the engineering department. So the guy is probably a tech-savvy artist rather than an art-savvy techie. And if you download the thesis you'll see that it is in fact "A thesis submitted in partial fulfillment of the requirements for the degree of MASTER OF PROFESSIONAL STUDIES in INTERACTIVE TELECOMMUNICATIONS at the Tisch School of the Arts, New York University"

      So don't worry. You can still be proud of your engineering PhD when you get it.

      Still, you have to admit that even though the underlying tech is nothing new, he does present some fairly novel usage cases for it. Of course most of them are fairly pointless like "let's collaborate together by looking at completely different things on the same screen". But the idea does seem to make sense for something like the split screen mode in 2-player video-games. If you can only have 512x768 pixels out an XGA display for your view, wouldn't you rather have those spread over the whole screen than squished onto one half of it, like they typically do? And if the other guy can't see what you're doing, all the better.

      Anyway the point is these lenticular screen 3D monitors that various companies are starting to make may have a variety of interesting uses beyond just displaying 3D imagery. Exploring those ideas is probably worth a master's degree in "professional studies," whatever that is.
