Auditory interfaces offer a solution to the problem of effective eyes-free mobile interactions. However, a problem with audio, as opposed to visual displays, is dealing with multiple simultaneous outputs. Any audio interface needs to consider: 1) simultaneous versus sequential presentation of multiple audio streams, 2) 3D audio techniques to place sounds in different spatial locations versus a single point of presentation, 3) dynamic movement versus fixed locations of audio sources. We present an experiment using a divided-attention task where a continuous podcast and an audio menu compete for attention. A sequential presentation baseline assessed the impact of cognitive load, and as expected, dividing attention had a significant effect on overall performance. However, spatial audio still increased the users' ability to attend to two streams, while dynamic movement of streams led to higher perceived workload. These results will provide guidelines for designers when building eyes-free auditory interfaces for mobile applications.
