One Screen, Multiple Views

Unknown Lamer posted about a year and a half ago | from the digital-catan-expansion dept.

Displays 43

First time accepted submitter e-sas writes "Researchers from the University of Bristol have built a new type of display which allows both a shared view and a personalised view to users at the same time. Through the two view-zones, PiVOT provides multiple personalized views where each personalized view is only visible to the user it belongs to while presenting an unaffected and unobstructed shared view to all users. They conceive PiVOT as a tabletop system aimed at supporting mixed-focus collaborative tasks where there is a main task requiring the focus of all individuals of the group but also concurrent smaller personal tasks needing access to information that is not usually shared e.g. a war-room setup. Imagine you and your friends playing multiplayer Starcraft on one big screen instead of individual computer screens!"

This thing is as clear as mud. (2, Insightful)

Anonymous Coward | about a year and a half ago | (#41754493)

The summary makes zero sense, and looking through the article, it's equally as confusing.
From what I could gather from the video, it's just a tablet of sorts that shows different images depending on your angle.
I'm still not even sure of that though, anyone here want to translate it to idiot speak for me?

Kenoli (934612) | about a year and a half ago | (#41754609)

It's a nonsense device. The summary is also awful. Multiple users playing Starcraft on one screen? Nobody would ever want to do that, especially not at the crazy viewing angles the device uses.

Mario Kart on the other hand would completely rock if you cold have two different players full screen on the same screen on the same couch.

Isn't this already more or less possible.
An LCD TV with 240Hz referesh and 4 tuners could allow with glasses Me to Play Battlefield 3, The wife to watch Greys Anatomy and the kids could watch different movies or a single 3D movie together.

Until the wife starts wanting to talk to you about what's going on with the show. You can always reply "Let me know when he's on screen again, I'll go for a headshot."

The 3D TV's already have this. 1 set of glasses would see one image, and the other set would see a second image. Not a good deal for spectators though.

jitterman (987991) | about a year and a half ago | (#41755071)

You pretty much got it.

Further, by placing an opaque "marker" on the screen to see your "personal view" you've just obscured part of other people's "public view," meaning you're still blocking the screen. I declare this "technically interesting but otherwise inane" technology.

good for presentations, not much else (3, Interesting)

locopuyo (1433631) | about a year and a half ago | (#41754527)

The technology is pretty cool and there are some uses for it but I think in most cases it would just be better to have multiple screens.
The only times I really see much use for is slide show type presentations. The presenter has some extra notes he can read while the audience just sees the slides.

old news (4, Interesting)

gbjbaanb (229885) | about a year and a half ago | (#41754551)

my (next) car already has this: a split screen view [thecarconnection.com] so the driver can see the satnav while the passenger can watch movies or TV (with headphone support to avoid distraction)

Re:old news (1)

epp_b (944299) | about a year and a half ago | (#41755045)

I was going to say roughly the same thing. I recall seeing exactly this on an episode of Top Gear.

Re:old news - not really (0)

Anonymous Coward | about a year and a half ago | (#41780051)

And what you don't get while jumping to this conclusion is that this display delivers more than one view in the personal space. So does your fancy already-been-done satnav allow your third passenger to play a game instead of watching the show the second passenger wants? no? this system does.

No, no, did not read full article. (4, Insightful)

Animats (122034) | about a year and a half ago | (#41754585)

They put a reflective film on a LCD monitor and aimed a projector at it. [bris.ac.uk] If you're almost perpendicular to the display, you see the projected image; otherwise you see the LCD image. The setup is that the display sits flat on a table and the projector is overhead, pointing down. If you lean over the display, the image changes. The room lighting has to be dim for this to work.

It's cute, but the applications are limited.

If you really wanted many people to see different things on the same screen, the various tricks used for 3D (shutter glasses, polarization) would be more effective.

"If you really wanted many people to see different things on the same screen, the various tricks used for 3D (shutter glasses, polarization) would be more effective"

I really should have followed up on patenting that when I thought of it in 1996; Initial patent search didn't come up with obvious prior art, but being unemployed at the time I didn't have money to pay a patent attorney, and no clue how to go about getting VC funding. I also dropped it because of the Pokemon seizures, I figured shutter glasses might have the same effect (and 3D movies just give me a headache anyway)

But, if it ever becomes an issue for patent trolling, I kept the documentation from the original patent search/lawyer contact.

LG and Samsung agree with you [channelnews.com.au] .

There are problems with shutter-glasses though (aside from the headaches, diziness, etc some experience). The more people viewing, the more images you need to be switching through, so the smaller the segment of time you can display the imagine to each user.
i.e.
2 people: each gets 50% timeshare of display
3 people: 33% timeshare
4 people: 25% timeshare. I imagine the display is looking getting pretty dim by this point.

With polarisation, you (to my understanding) simply can't present more than two images because you need the two polarisation angles to be relatively perpendicular. You can't add a third polarisation angle to get a distinct image.

Even combining technologies will probably not help, because each one still dims the brightness of the image.

I agree entirely but I figure it's due to Sony putting up a brick wall [uspto.gov] in that direction.

What's up with that square object they need to put on top of it and move around to see some small personalized part? It doesn't seem practical if you need to place something on top of it just to view something...

This would also be fantastic for Artemis! Captain gets his big viewscreen, but the crew can look at the same screen and get the info they need to do their job!

Poor solution to a problem with existing solutions (1)

tgd (2822) | about a year and a half ago | (#41755585)

I saw systems doing separate views using a lenticular lens screen (like you see on 3D advertisements) to show different views to different users back in the mid 90's in a university research lab. They claimed it was new, who knows. I saw it again in the early 2000's, again claimed to be new. I've seen it claimed as new twice in a particular large company's R&D division, and these guys are solving the problem in a clunky way. Maybe their lousy solution is new, but the solution space itself sure isn't.

If it was actually a useful solution, it would've entered production any time in the last 18 years since I first saw it.

Sony's "two people playing on a single monitor" capability in their new monitor for the PS3 is the closest I've seen, but it requires active shutter glasses.

Anonymous Coward | about a year and a half ago | (#41755961)

You are correct that Sony's product is the most successful commercial version. Note that the principles behind Sony's technology were first described in my M.Sc. thesis, and a paper I published in 2001:

http://dx.doi.org/10.1145/365024.365349 (if you have ACM access.)

Japan had them in the 90s.
They advertised it as being for dads who wanted to watch baseball but couldn't because their shitty families always wanted to watch shitty crap.

So the family is watching the tv from the center of the (tiny) living room, and dad's off in the corner with a beer, watching a baseball game on the same screen.

playstation 3 supports that on 3dtvs (1)

godrik (1287354) | about a year and a half ago | (#41755601)

I saw a demo where two people where playing full screen on a tv by calibrating 3d glasses properly. That was convenient for an FPS deathmatch.

Re:playstation 3 supports that on 3dtvs (0)

Anonymous Coward | about a year and a half ago | (#41757849)

I've seen this too. Basically you get 2 2D views and the glasses are both polarized in a single direction (as opposed to one direction per eye). I'm not totally sure but I think you have to have a special set of glasses. I doubt normal 3D ones can be adjusted this way. I immediately thought of screen cheaters losing their minds. I also think it would be great for just about any game that tends to be compromised with multiple players. Racing, sports, fps, just about all genres of games would be awesome for this application.

Re:playstation 3 supports that on 3dtvs (1)

locopuyo (1433631) | about a year and a half ago | (#41758337)

But you still hear the other player's sounds unless you also do something similar with headphones.
Also it doesn't work as well as the 3D alternating shutters because you are alternating for the same amount of time seeing an image and seeing nothing. Along with that you also could be losing a lot of visual quality because you're getting half your potential frame rate.

Re:playstation 3 supports that on 3dtvs (0)

Anonymous Coward | about a year and a half ago | (#41765321)

The 3d tvs that use active shutter wouldn't work so well with this, but the 3d that uses two images polarized at different angles, the framerate remains unchanged.

Sony already did it (0)

Anonymous Coward | about a year and a half ago | (#41756801)

There was a TV they made and showcased it with a racing game. where player One sees their side and player two sees their side. I believe it was achieved with used of special glasses though.

Question is, is it cheaper then 2 montiors? (1)

Nyder (754090) | about a year ago | (#41759151)

When you can buy 1080p monitors for as little as $100, is it worth it? I paid $360ish for my 120hz 3D Vision monitor. I could of bought 3 monitors instead with that price. Sometimes I wonder if I should of.

Sounds like a gimmick to me, sort of like 3D movies. Yet they keep beating that dead horse.

I can see the divorce rates skyrocketing... (1)

GrantRobertson (973370) | about a year and a half ago | (#41761303)

With two separate views and a touchscreen interface it is only a matter of time before people start smacking each other's hands and fighting for screen real estate. It would be so much easier to simply use two monitors. They aren't that damned expensive.

New? (1)

wiedzmin (1269816) | about a year and a half ago | (#41783643)

Come on, Landrovers had this on their dash for years, where the driver sees a GPS while passenger sees a movie, on the same middle screen. Way to slashdvertise something...
