As some companies try to increase the quality and functionality of high-definition touchscreens for miniaturized, mobile applications, others are moving in the opposite direction -- blowing up the size of multi-touch displays to create a completely new way to experience the advanced technology. MyMultitouch, a German company focused on multi-touch solutions, showed off its state-of-the-art 84-inch multi-touch display at this yearís CeBIT in Hanover, Germany.

The monster of a display is a definitive change of pace from the usual smartphone and tablet touchscreens. Rightfully named the Alvaro GIANT, the 3,840 x 2,160 Ultra-High Definition display outputs at 4K resolution as it sits atop an equally large metal structure that allows the screen to rotate from upright to a completely flat position. The display accepts any HDMI, DVI, AV, RGB, USB, or DisplayPort input, and even offers an integrated Windows 8 system for standalone use. With only a 12mS touch response time, the LED Cell imaging technology used for the touch display allows up to 32 simultaneous touch points and can even differentiate between different hand positions making contact with the screenís surface. The bezel contains an array of LEDs used to detect light breaks at the surface level. A fairly old touch detection method, often used in an industrial environment. It is nice to see the same tech can handle 32 simultaneous inputs.
Unlike most other touch displays of this kind, the Alvaro GIANT has something others lack: a price tag. The 84-inch screen will retail for $43,000 US and is mainly targeted for public display applications, such as retail or museum exhibits, as well as other educational and industrial uses. Designed for continuous, 24-hour operation, toughened safety glass and a rigid metal case ensure the GIANTís reliability in public settings.
Pricey? You bet! But, thatís to be expected from a mammoth of a display capable of multitouch. The Alvaro GIANT will run off of any Windows OS as far back as XP, as well as Mac OSX, Linux, and Android. So, yes -- if you happen to have that much extra cash lying around, you can indeed play Angry Birds on the 84-inch screen. Check out the video below of the folks over at SlashGear giving the Alvaro GIANT a test-run at CeBIT.
Yes, there were touch screens in Minority Report. I don't remember them in Back to the Future II. Mostly I've seen them -- real ones -- in political maps during campaigns. Chuck Todd, among others, is very good at using one effectively.
There have been large touchscreen for some time. They were called "Microsoft Surface" at that time. Now that name is used for smaller screens. They sported up to 32 inputs. Some even had depth sensing, if I recall.
However, this size is unprecedented. I am sure the price would shock as well.
A multi-touch display boasting an 84-inch screen and an ultra-HD resolution is some fine piece of engineering and a marvel in its own right. The touch response time is mighty impressive as well. Considering that it also comes with a toughened safety glass for panel protection, the makers have left very little to complain about. Support for stereoscopic 3D would've been the icing on the cake. The only barrier to entry is the hefty price tag.
I agree with some of the above comments. Prices will decrease for 4K resolution paired with 84" monitors over time. With the price tag today only a select market is capable of purchasing these displays. Here is another interesting article highlighting touch screen and 4k content
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isnít a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
