An expert at the University of Berlin has designed an audio-enabled space, termed the 'BoomRoom', which will let the user listen to his or her emails, twitter feed or texts without touching any gadget screen.
According to Discovery News, Jorg Muller's room has 56 loud speakers that direct sound to stationary positions and 16 gesture-recognizing cameras that let users control the audio and even "touch" an email to open it and have a computer read it out loud. It is also worth noting that Muller's invention uses the wave field synthesis technique that builds 3-D sound fields to either cancel or reinforce sound waves with constructive or destructive interference, to place sound at pinpoint locations.
