Experiments in spatial mobile audio-conferencing

With improvements in digital cellular networks, and greater pervasiveness of wireless communication, mobiles phones begin to support multi-party calling. Due to hardware limitations in current models, speakers are presented in a single audio stream, causing confusion and decipherability issues. The case for using spatialised audio is strong from other domains, and here we present an interaction approach to realising spatialised audio for multi-party calls in mobile contexts using motion-tracking. Our study suggests that phone tracking is a viable option for orienting to speakers in virtual spatial audio environments on mobile devices.
