Stock up on coasters. A new technology combines the coffee table with a universal remote so that people sitting around the table can tap on a screen to change the channel, turn up the volume or dim the lights.
CRISTAL (Control of Remotely Interfaced Systems using Touch-based Actions in Living spaces) is a research project in user interface that attempts to create a natural way of connecting with devices. The system offers a streaming video view of the living room on a tabletop, so users can can walk up to it, see the layout of the room and interact with the TV or the photo frame.
“We wanted a social aspect to activities such as choosing what to watch on TV and we wanted to make the process easy and intuitive,” says Stacey Scott, assistant professor at the University of Waterloo in Ontario, Canada, and a member of the project. A demo of CRISTAL was shown at the Siggraph graphics conference earlier this month.
The idea isn’t completely novel. Microsoft showed off Surface, a multitouch display in 2008 that allows users to interact with it by using gestures.
Universal remotes have become popular in the last few years, but they are still difficult to use. Their greatest flaw, though, may be that they do not help quash those battles over who gets the remote. CRISTAL solves those problems, says Christian Müller-Tomfelde, an Australian researcher who is currently writing a book on research in tabletop displays.
“It is a clever use of the tabletop as a ‘world-in-miniature’ interface to control room elements,” he says.
Scott and researchers from the Upper Austria University of Applied Sciences have been working on the idea for less than a year. It started when Michael Haller, the head of the Media Interaction Lab at the university, found himself frustrated with different remotes for each device: TV, radio and DVD player.
“Every time you get a new device into the living room, you get a new remote with it,” says Scott. “And instead of difficult programmable universal remotes, this offers intuitive mapping of the different devices and home.”
CRISTAL uses a camera to capture the living room and all the devices in it, including lamps and digital picture frames. The captured video is displayed on the multi-touch coffee table. The video image of the device itself is the interface, so a sliding gesture on the image can turn up the volume of the TV, for instance. To watch a movie, drag an image of the movie cover and drop it on to the TV on the multitouch screen.
But it will be a few years before this remote is available at Best Buy. It could take five to 10 years before affordable multitouch tabletops can be created for consumers, says Müller-Tomfelde. “The investment to get such a coffee-table display into the living room is not to be underestimated, as we can see with Microsoft’s Surface technology,” he says.
Scott estimates that a tabletop remote such as CRISTAL could cost $10,000 to $15,000. But she is confident that the idea can become viable enough for consumer production in a few years, especially if it can be combined with Microsoft’s Surface product.

While I was at Radio Shack the other day, I saw two things that caught my attention. The first was the sign out front was not changed to “The Shack”, even though they officially changed their name to that about a month ago. The two guys working there didn’t seem to know if or when that sign would be changed either.
