Spatially augmented audio delivery: applications of spatial sound awareness in sensor-equipped indoor environments [PDF]
, 2009 Current mainstream audio playback paradigms do not take any account of a user's physical location or orientation in the delivery of audio through headphones or speakers. Thus audio is usually presented as a static perception whereby it is naturally a
