The World's Largest Touchscreen
An anonymous reader writes "The University of Groningen, in the Netherlands, has converted a 3D theater into the world's largest touchscreen, used for teaching mathematics and computer science students interactivity. The screen has a curvature of 135 degrees and is transparent."
How about linking directly to the source, instead of to this blogspam: http://www.rug.nl/cit/hpcv/nieuws/touchscreen1
If you go to the source at http://www.rug.nl/cit/hpcv/nieuws/touchscreen1 you will see that it wasn't created for teaching math at all (the blogspam linked from the story seems to have made that up). According to RUG: "the initial goal was to facilitate the scientists studying Geographic Information Systems and a research group that studies interaction methods for touch screens"
This has resolution equivalent to two 4k screens and is LCD technology where that looks like projectors. http://www.evl.uic.edu/core.php?mod=4&type=4&indi=727
