Abstract
This paper proposes a method of evaluating the effect of
auditory display techniques on a complex visual search task.
The approach uses a pre-existing visual search task (conjunction
search) to create a standardized model for audio, and non-audio
assisted visual search tasks. A pre-existing auditory display
technique is evaluated to test the system. Using randomly
generated images, participants were asked to undertake a series of
visual search tasks of set complexities, with and without audio.
It was shown that using the auditory feedback improved the
participant’s visual search times considerably, with statistically
significant results. Additionally, it was shown that there was
a larger difference between audio and non-audio when the
complexity of the images was increased. The same auditory
display techniques were then applied to an example of a real
complex visual search task, the results of which imply a significant
improvement in visual search efficiency when using auditory
feedback.
