Many hands make light work – and on a giant touch screen those hands will be able to work far more efficiently than ever before.
That is the claim for the world’s biggest touch screen – here at Groningen University in the Netherlands.
The huge converted 3D screen allows a new kind of collaboration, according to one of its developers, Frans van Hoesel.
He says, “You can work on that part of the screen, somebody else can work on the other part of the screen and we can communicate with each other. This is just for fun of course, but you can envision more serious applications.”

Behind the screen are six full-HD rear projectors, six Optitrack cameras, 16 infrared sensors and nearly 1000 LED’s.
At least 100 points of contact can be detected simultaneously, giving a much greater feeling of control of the data than that provided by a mouse, says Computer Sciences Professor, Tobias Isenberg.
Isenberg says, “The mouse is a very small, precise instrument, whereas your finger covers typically a bunch of pixels so you have to deal with this issue of precision, then you can not just use menu-driven systems, as you know them traditionally from computer interfaces, because they would in large setting like this end up somewhere on the top of the screen, whereas you want to interact locally, so the whole difference of interaction interfaces has to be taken into account.”
The team is exploring applications for technologies that benefit from scale like astronomy – where larger images will help researchers.
They say that overcoming the issue of manipulating 3D data on a 2D surface can wait. For now, its just size that matters.
Bottom line: The team behind the world’s largest touch screen says the huge device changes the way we work and interact with data. The screen, at Groningen University in the Netherlands, is based on a 3D cinema screen 8.5m wide by 2.7m high (28×9 feet).
