"TransWall" utilises both sides of a large, transparent screen to produce an interactive touch pad accessible to multiple users at once It comprises a thin holographic screen sandwiched between two sheets of plexiglass. Overhead projectors on each side beam images that can be manipulated, onto the glass, while a surface transducer and two microphones transmit vibrations and audio through the wall in both directions. The screen was developed by a team at the Korea Advanced Institute of Science and Technology, led by Professor Lee Woo-hoon. (SOUNDBITE) (Korean) PROFESSOR LEE WOO-HOON, THE KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY (KAIST) SAYING: "When it comes to conventional displays, people are looking in the same direction. But people can do something while facing each other through 'TransWall'. Through the transparent wall, people could share visual content that would be more sociable, more fun, with lots of communications among the people. We could use it as an enjoyable medium." And not just in the home. The team says "TransWall" has application in public spaces as well. (SOUNDBITE) (Korean) PROFESSOR LEE WOO-HOON, THE KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY (KAIST) SAYING: "It can be installed in a subway station, museum, or shopping mall. Public displays would be located at the centre of the space instead of hanging on the wall. People could watch and touch the visual contents, and enjoy gaming," Lee says he hopes "TransWall" can soon be commercialised to make transparent display technology a new interactive part of everyday life.
