1:23 pm
3Di has a new Autostereoscopic display that is also a Touchscreen, and calibrated for 3D effects at (convenient) arm’s length. Meant for kiosk uses, it incorporates a few new patents from 3Di into a new 1080p display.
“The screen can be perfectly used and incorporated into vending machines, kiosks and infotainment systems”, said Stephan Otte, Head of Hardware Development in 3D International Europe. “We are very pleased to offer one of the first glasses-free 3D multi-touch display products in the market at an affordable price.”

Reality Touchscreen at University of Groningen
4:00 pm
Now this is a cool touchscreen! I could see this being used in an actual class instead of just as a tour stop.
This is the curved screen in our reality center of the University of Groningen. We just finished building our own touch detection for it. We used six Optitrack v120 slim camera’s which have a good sensitivity for infrared light. We used 16 cheap infrared emitters (the kind used for security systems) with a total of 1000 LED’s.
The touch detection software runs on three old computers each with two camera’s connected. One extra computer combines the output from the detection computers and send event data to our main visualization system.
This way we have (even using the old computers) enough processing power to be able to run the detection software at 60Hz and with a latency between 30 ms and 50 ms. It can detect without any problem 100 different touches at any time (more is possible, but it becomes slower)We used a modified version of Community Core Vision (CCV) 1.4 (nuigroup.com) (modified so it can do two camera’s on one computer). The communication protocol is preferable TUIO (tuio.org) and we did install Multi-touch Vista (multitouchvista.codeplex.com), which translates TUIO events to WM_TOUCH events for windows 7. The demos you see in the video are from Multitouch for Java.
The curved screen itself is consist of a 3 mm dark acrylic layer, coated with a diffuser on the front. Illumination is from behind using six full HD projectors. The cameras and the IR-leds are also located behind the screen.

HP’s Wall of Touch
9:00 am
The Wall Street Journal has an article today on HP showing a new “wall of touch”. This is a standard display wall comprised of six LCDs. Each LCD can be anywhere from 43″ to 46″ and is capable of 1080p resolution. Philip McKinney, Vice President and Chief Technology Officer of H-P’s Personal Systems Group, showed the setup to the Journal.
He said “wall of touch” will not be widely available to consumers until 2011, and would likely come with a hefty price tag: anywhere from a couple thousand dollars up to $100,000 for more advanced systems with technologies like HD video conferencing.
I would expect that the cost would be a couple thousand dollars for a single screen, since 42″ LCDs are hovering around one thousand dollars.

Light Touch projectable touch-screen system
10:00 am
Light Blue Optics, which is located in Cambridge, UK, has released a new product called the Light Touch. This device was shown at the Consumer Electronics Show in Las Vegas last week. The Light Touch system projects up to a 10 inch image onto a flat surface, with a WVGA (probably 800×480) resolution. You can then interact with the image, effectively making it a touch screen. Light Touch accomplishes this by using an infra-red touch sensing system.

Microsoft SideShow could offer gamers secondary touchscreen
4:00 pm
Microsoft is resurrecting an old idea, the “SideShow”. For those of you who don’t remember it, it’s a small display set up near your main display for showing other context data. Now touted with touchscreen capabilities and such, they’re retargeting it at gamers for use as an additional data display for in-game maps, health, inventory, etc.
With devices like the Intuos offering something similar (albeit with alot of extra nicer features), and things like Mimo Monitors connected via USB, is the time finally right for this? Or just another unnecessary gadget?
