The Hidden World of Noise and Voice
In this multi-user augmented reality system, sounds are converted into graphic information in accordance with both their tonal characteristics as well as their spatial sources. This means that the computer localizes, for example, a person snapping his/her fingers and visualizes by means of diverse algorithms and relational models a graphic analogue—for instance, in the form of a small explosion—on the hand of the person doing so. If someone makes a deep, indolent sound, this gets depicted as a sluggish, fat 3-D graphic—like a fat worm wriggling out of the person’s mouth. Abruptly pronounced sounds likewise evoke objects that correspond to them in form and behavior. Thus, the sounds—or rather their visual correspondences (avatars)—successively fill the previously empty space with a dynamic and lavishly realized world of computer graphics.
