BoomRoom's sound by design uses array of loudspeakers
(Phys.org) —Jörg Müller, a researcher at the Technical University of Berlin, thinks of ways to make effective use of sounds in human-computer interactions. He and his team explore how to direct sounds in a focused way, and their concept is called the BoomRoom. A report in New Scientist talks about the-audio-enabled "BoomRoom, where a ring of 56 loudspeakers allows sounds to be assigned stationary or mobile positions in the space around the person. In a paper for the upcoming ACM CHI Conference on Human Factors in Computing Systems, which will be held in April in Toronto, Muller, Matthias Geier, Christina Dicke and Sascha Spors explained: "The BoomRoom allows for direct manipulation of virtual sound sources hovering in mid-air." The BoomRoom also enables ordinary objects to appear to emit sounds. Boom-Room uses Wave Field Synthesis (WFS), and optical tracking. "Loudspeakers and cameras can be at a distance from where the...
