Smartphone-Style Touch Sensing On an 82-Inch Screen
An anonymous reader writes "Those giant touch screens used by CNN anchors look slick, but have to be several feet thick to make room for the cameras that track the touches. Perceptive Pixel, which makes the screens, has now figured out a way to use capacitive touch (like on an iPhone or tablet screen) at a larger scale, and says giant touch panels with 82-inch screens but just six inches deep will appeal to many businesses."
I'm sure they'll be in huge demand. At least, they'll be in demand till Apple hears about the 'iPhone-Style' touch and sues them out of existence!
For anybody who doesn't recognize the company name, they're the same guys behind this old footage:

No, they really don't. Can we please go back to when professional artists made the graphics and let the mouthwhores go back to reading their teleprompter rather than faffing around with a big screen.

How the hell are you supposed to fit something that big in your pocket? ;-)
THIIIIIIIS BIG.
I'll need these to swing my arms out and accurately gauge it with an expanding picture of a fish.
So how about "surface"?
No, really, there are a number of ways to solve this problem.
There exists a musical instrument, a theremin, that alters tone based on 3-dimensional proximity. A pair or triplet of them should give a nice no-touch input in 3d space with appropriate digitization and calibration without the lag of the 3-d camera approach.

It's a 1920x1080 HDTV with touchscreen capability. That resolution is fine for viewing from 10-15 feet away, or if you're broadcasting it on TV. But if you're right in front of the screen touching it, it works out to an underwhelming 27 DPI. The pixels are nearly 1 mm square. I'm not sure this will work as the whiteboard replacement they're envisioning.
More tech that some teachers will think they need in the classroom now that it's mass producable. Mind you, they use the current smartboard as a screen only or just to let the kids amuse themselves after the lesson has concluded, and the document camera serves only as a replacement for the transparency and overhead projector. Let's take an already overpriced, underused setup at ~$300/2000hr bulb and instead install a setup that's probably many times that, so little Skyler can virtual-fingerpaint at the front of the class instead of using chalk on a board or dry-erase markers.
Some teacher is writing a grant proposal right now, mark my words...
Do not look into laser with remaining eye.

Yeah, let's stick with professionals. For the lulz.

While the presenter is near the pixles, the viewers are not so it works out fine. Please remember that existing digital whiteboard tech like Smart boards make use of normal DLP projectors, and so are often 1024x768. It is fine up close. Yes you can see the pixels but you can still see what you are doing.
Also I would presume they wanted to bring it to the market for a price people might actually buy. 4k displays are retardedly expensive, like $50,000-$100,000, and I'm not even aware of any in the 80" range. For all if you could do it you'd still only be talking 54 DPI up close.
Ultra high rez sounds cool and all, but it will take some time before the tech is there to make it cheap.
The article seems to think that anything more than about the size of an ipad has to be inches thick. The computer I am using at the moment is about 3 inches thick and that includes the CPU/disk/memory. It is a 23 inch HP touchsmart. It has two finger multi-touch and some Microsoft surface apps running on it.
What am I missing? I can not think of a reason you would need more than at most 4 contact points unless you wanted to finger paint. I rarely use more than one finger at a time and in most cases just use the mouse.
Much larger than about the 23 inch screen I have would be overkill if you were within arms length of one unless you were doing a presentation or some sort of group project
I obviously missed something here.
Just this Monday we were filming for a TV programme and we used these guys to demo an iPad app on a giant touchscreen. It's still early days for the technology, but it works well for that use case already.
Instead of increasing their display tech to use lower power and have less noise, they've thrown money at the challenge of filtering out the excessive electrical noise to sniff the low level capacitive signals. IMHO they have missed something.
In the process, they've lost the entire large format graphics industry. I would like to have about a 64(+/-) inch display which has both finger and stylus input - though admittedly at 72-125ppi. Why? Architectural drawings. The largest practical paper set is 30x42", which will fit on a 62" 16:9 format screen with "toolbar" space on the side. At 64" you can get a title bar and menu across the top. But it has to have a fine-line ability with a pen input for markup.
I chuckled at the "Architects collaborating" part of the article. No, they will spend thousands of dollars to create neato 3d renderings for high end clients which now work with fingers and hands for navigation instead of a mouse/air mouse. The real work still gets done in a super-precise model space which requires very accurate input, and still occurs in large part on paper with pencil.
Is it just my observation, or are there way too many stupid people in the world?
How many touches can it recognize at the same time? A screen that size really needs the capacity for 10-24 touches simultaneously. I thought the issue with capacitive multi-touch solutions was occlusion of touches on the same row or column. I suppose I haven't been tracking the tech for the past few months.
to play angry bird on THAT one.!!!
