ABSTRACT The authors describe an artistic exploration of sound in space enabled by real-time computer vision algorithms that provide hand shape and 3D hand-tracking information.

The author presents a creative and technical practice using flat flexible audio speaker surface arrays. These arrays can be formed to various environments, offer diverse design possibilities and allow for user interaction. This practice provides an alternative to traditional models of sound reproduction by considering how visual and physical material could be construed as sound itself. Taken as art material, these surface array systems open up unique possibilities for acoustic spaces, composition and sound interactivity.

ABSTRACT The authors discuss Chronography: animal , a live electroacoustic work based on sound recordings Needham gathered in Antarctica in 2009, along with related works.
