'Smart' table could boost brainstorming

By Tom Simonite A ‘smart’ table that copies images of objects on its surface to a video display below could improve brainstorm sessions, researchers say. The Blue Eye table consists of a glass surface with a camera overhead and a projector and a mirror underneath. A user places an object on the glass surface and presses a button to copy it to the screen beneath. Once imported, the images can then easily be moved, stretched and even animated by a user. “You can take objects, put them onto the board and they are instantly imported into the digital screen,” says Bastiaan Ekeler from Eindhoven University of Technology in the Netherlands. When an object is placed on top of the table, the digital camera overhead captures an image and software cuts around it by distinguishing it from the background. Existing digital images can also be added to the system by dragging them into a computer folder on a connected computer, Ekeler explains. The current version of the display requires a user to then manipulate the images by touching them with special plastic shapes. The shapes feature markers that are recognised by an infrared camera above the table and their movements are translated by computer into image manipulation commands. The team is also planning a version that uses hand-gesture recognition for image manipulation. They have created a video mock-up showing how users should be able to create collage of images and animations with such a polished system. The video prototype was partly inspired by the similar Cabinet system developed by Ianus Keller at Delft University of Technology, also in the Netherlands. Jean-Bernard Martens, the visual interaction specialist leading the project, says early trials have been promising. “We’ve been running a trial with designers that use ‘mood boards’ in their work,” he told New Scientist. “They especially liked the feeling of having the images under their hands.” Details of Blue Eye were presented at the British Computing Society’s Human Computer Interaction Group conference at Queen Mary, University of London, UK,
