Microsoft's no-glasses 3D display

3D television may be on the rise, but let's be honest--no one really wants to put on a clunky pair of glasses whenever they sit down to vegg out. According to TechnologyReview, Microsoft's Applied Sciences Group is working on a new type of lens that may send 3D TV's worst accessory packing.

This new type of lens is thicker at the top, thinner at the bottom, and is able to guide light to a viewer's eyes by turning light-emitting diodes, located at the bottom edge of the display, on and off. It also has a backlight and can be used instead of backlights found in traditional LCD displays. This sort of setup allows different images to be shown to different eyes, of different viewers, leading to a 3D effect. To accomplish this intimate delivery of images, a camera is used to track the eyes of those watching the screen.

As of now, the technology is still pretty limited, and probably won't be seeing the inside of your living room anytime soon. The current prototype can show a 3D image to a maximum of two viewers at the same time, regardless of what angle they are sitting at. This differs from other glasses-less displays that have been developed by other companies which require users to sit at specific viewing angles. With a 2D image, four people can watch at the same time. This makes the display useless to larger families and large gatherings (read Super Bowl and World Cup).

Until this sort of 3D display matures, practical application of this technology would include smaller electronics, such as handheld gaming systems, smartphones, and other portable devices. If applied correctly, this particular lens could also allow users to direct light to their eyes only, removing the need for privacy protectors when dealing with sensitive information at work. No production plans have been announced.

Maybe you havent used those new glasses without the blue and red.

or maybe they only have monocular vision

There is a % of people who can't see the 3D effect with the glassess, it's a well known case, I just forget what the % is.

I wonder if I'll be able to see the 3d effect properly.... With the glasses I can't see 3d at all

Neither can I Rudy. I'm red-green colorblind. It's a b*&&h, but then there's never been a 3-D movie I truly wanted to see before Avatar, which was good even in 2-D @ the drive in.

Also what if you wear actual glasses? Will reflection from the lens cause problems and such? Mine are slightly tinted so even that could have an effect on whether the 3D is displayed or not.

It sounds like it tracks the location of your eyes so it would send the light to your eyes and which shouldn't be any different than the way you view the world now with your glasses.

Except it might have an issue with tracking eyes that are behind a reflective surface, not to mention projecting the light through that reflective surface. Still, I doubt anyone here (unless some MicroSoft researcher is browsing the forum) would be able to give an accurate answer.

Exactly my point. Physics 101.

Would be nice.

Why is this so complicated? If the device can track your eyes, what makes you think it cant track your face. If it knows where your face is and can't see your eyes because of glasses reflections or whatever you seem to think physics prevents, it knows it just has to send one image to half of your face and another to the other half of your face. Stop over thinking. It isn't that hard of a concept.

I don't mind the glasses in a theater. But i will never be interested in 3D TV at home as long as glasses are needed.

Having to wear glasses for 3d is so 90's.
I bet these new 3D overpriced screens that require glasses will dissapear very soon from store shelves.
People buying them now are going to regret it.

Because a TV that tracks all viewers in the area, sends two separate beams of light to each of those views eyes is going to be cheaper?

Also, those people that are "going to regret it" are currently watching movies in a way that we don't get to experience at home for a few more years at the least. Those TV's cost just as much as any other big screen and when the new tv's come out, the same people that could afford the "overpriced screens" that you can't afford will be the same people buying the latest and greatest when you still can't afford it. Do rich people regret buying the car they bought last year every year when they get the newest model?

Now this would be very nice for the next Xbox

Correct me if I'm wrong, but the X-Box isn't a device for displaying media, it is a gaming console that you connect to your TV (The device for displaying media) and use to play games. As such, how can this feature be included on an X-Box? I'd think if you got the TV and the X-Box was compatible with said TV, you'd probably be able to use the feature, but it sounds like something that would be fix-able with a software patch, not something that needs new hardware to be used. (Apart from the TV itself)

Its Xbox; Not X-Box....

I was saying that for the next gen Xbox, it could be compatible to output 3D data and non 3D data to a compatible 3D display or non 3D display.

Don't really care to be honest. Never wanted one, probably never will have one. Not that big of a deal if you ask me.

Still sounds like a software issue rather than hardware. I'm fairly sure they're not coming up with some brand new interface along the way either, so if your "Xbox" has an HDMI, it can still send the proper data through that channel. I might be wrong, but it still doesn't look like a feature that can't be added to the old "Xbox" either.

MS approach sounds superior but in the interim other stuff is on the way already:

3D Eye Solutions also showed off no glasses 3d tech at CES2010.

Read the post, it says that there are other glass-less TV projects that are currently being worked on, but they are limited by the position that people need to stand in to actually see the 3D effect:

This differs from other glasses-less displays that have been developed by other companies which require users to sit at specific viewing angles.

This thing, on the other hand, would use a camera to track people's position so they do not have to rearrange their whole living room just so they can watch 3D:

yeah...hence why I said MS solution sounds superior. I was illustrating to others some of the tech and approaches that are on the way. Get off your "read the article" bandwagon, take two steps back and pop a chill pill.

Sounds like too much trouble technologically.
A better way would be to tap straight into the visual cortex by strapping some sort of device to the back of the head. Come to think of it, that wouldn't be the easiest thing to achieve either.

What's next? Snap your fingers, your forehead opens up and you hook up to the computer via a wireless data link that streams the movie directly to your brain?

I have got the V screen for the PSP this has been out for mounths now it converts the PSP to 3D developed by realview.ie they are bringing out a deep screen which ataches to your TV which is a frenzil type screen which gives a depth efect it is very impresive more than one person can see this at a time duse not involve exspensive electronics , they are producing a 22inch screen for aprox $120
I have askd them to make me a 26inch 16.9 pannel for my TV should have this in a few weeks time it converts every thing to 3D !
