Urban exploration using audio scents

We describe the design and evaluation of an audio-based mixed reality navigation system that uses the concept of audio scents for the implicit guidance of tourists and visitors of urban areas, as an alternative to turn-by-turn guidance systems. A field trial of our prototype uncovers great potential for this type of implicit navigation and is received positively by our participants. We discuss the technical implementation of our prototype, detailed findings from quantitative and subjective evaluation data gathered during the field trial and highlight possible strands for further research and development.
