Glasses-free 3-D TV at MIT

As striking as it is, the illusion of depth now routinely offered by 3-D movies is a paltry facsimile of a true three-dimensional visual experience. In the real world, as you move around an object, your perspective on it changes. But in a movie theater showing a 3-D movie, everyone in the audience has the same, fixed perspective — and has to wear cumbersome glasses, to boot.

Despite impressive recent advances, holographic television, which would present images that vary with varying perspectives, probably remains some distance in the future. But in a new paper featured as a research highlight at this summer's Siggraph computer-graphics conference, the MIT Media Lab's Camera Culture group offers a new approach to multiple-perspective, glasses-free 3-D that could prove much more practical in the short term.

Instead of the complex hardware required to produce holograms, the Media Lab system uses several layers of liquid-crystal displays (LCDs), the technology currently found in most flat-panel TVs. To produce a convincing 3-D illusion, the displays would need to refresh at a rate of about 360 times a second, or 360 hertz. Such displays may not be far off: LCD TVs that boast 240-hertz refresh rates have already appeared on the market, just a few years after 120-hertz TVs made their debut.

I can't predict the future. But I suspect it will be entertaining.

Good luck with rendering a game 3 times for the 3 layer display.

Hey There! Thanks a lot for this useful video. By the way, I notice a lot of people keep on talking about backlink services known as MoboRank (just google it), but I'm not sure if it's good. Have you thought about MoboRank? I've heard many great things about it and my mate improve his website's google ranking with it, but he refuses to tell me: (

That 3D is just a simple illusion almost the same as in the 1950s. This technology is so much more.

3DS - so what these guys at MIT are saying is that they are years behind Nintendo in 3D technology.

• Who are the competitors? Are there substitutes technologies?

• What are the advantages and disadvantages of existing Stereoscopic Vision technology?

• With which market segments will this technology make the greatest inroads?

And finally, we would appreciate if you can share with us some of your ideas and general thoughts about the future of this technology.

We greatly appreciate and thank you in advance for your time and any assistance you may offer.

We are students at the Tal Institute in Jerusalem Israel, currently studying Management and Marketing Technology.

In the curriculum, we are participating in a course called "Technological Forecasting".

In this course we are researching the technology and marketability of Stereoscopic Vision (three-dimensional TV without glasses).

We would greatly appreciate if you could help us by answering several questions on the subject:

אנו סטודנטיות לניהול ושיווק טכנולוגיה במכון טל שבירושלים.

במסגרת תכנית הלימודים אנו משתתפות בקורס "חיזוי טכנולוגי".

בקורס זה אנו עורכות מחקר בתחום טכנולוגיית ה"סטריאוסקופיה" בטלוויזיות התלת מימד (ללא משקפיים).

נשמח אם תוכל לפנות מעט מזמנך ולעזור לנו במספר שאלות בנושא לפרק חוות דעת מומחים שעלינו לחבר:
