ABSTRACT The authors discuss their interdisciplinary research, which investigates the use of affective computing technologies in the context of music, audiovisual artworks and video games. One current project involves the expansion of mobile sound walk apps through incorporating environmental and emotional factors, forming new sonic landscapes. What type of music could reflect driving through a hot desert landscape at midday or walking through a snowy cityscape at dawn? Through a discussion of their collective work in this area, the authors aim to elicit a vision of the computer-based musical experiences of the future.
