Use of Geospatial Data Sonification for Mobile Augmented Reality Audio Navigation
MetadataShow full item record
This paper presents MeanderMaps: a non-speech Augmented Reality Audio (ARA) application for Apple iPhone that aids in navigation purposes by sonifying geospatial data. Users request directions to a specified location on a Google Map overlay, and MeanderMaps uses spatial auditory cues such as distance and direction to guide him/her to the destination. As the user travels to consecutive waypoints known as path nodes, auditory cues indicate whether an incorrect turn has been made or if the user is traveling in the wrong direction. Preliminary findings are reported using qualitative and quantitative methods, evaluating the overall sonification model in addition to individual audio cues that (a) worked, (b) worked somewhat well, and (c) needed to be improved. Future improvements and modifications to MeanderMaps are presented.
