ABSTRACT

The previous chapter outlined the psychoacoustic theory behind cyberspatial sound, recapitulated in Figure 13.1, and the idea of audio augmented reality (AAR), including review of its various form factors. Whereware was described as a class of location-and position-aware interfaces, particularly those featuring spatial sound. This chapter considers application domains, interaction styles, and display congurations to

realize AAR. Utility, professional, and leisure application areas are surveyed, including multimodal augmented reality (AR) interfaces featuring spatial sound. Consideration of ( individual) wearware and (ubicomp) everyware is continued from the previous chapter, in the context of mobile ambient transmedial interfaces that integrate personal and public resources. Two more “…ware” terms are introduced: anyware here refers to multipresence audio windowing interfaces that use narrowcasting to selectively enable composited sources and soundscape layers, and awareware automatically adjusts such narrowcasting, maintaining a model of user receptiveness in order to modulate and distribute privacy and attention across overlaid soundscapes.
