<Wayfinding without Visual Cues:Evaluation of an Interactive Audio Map System-Esther Loeliger and Tony Stockman>

summary:

 This thesis tried to demonstrate that all users no matter they are blind can improve their way-finding performance with positional audio cues.
 This study is related to spatial knowledge and way-finding and auditory displays focused on ambient 3D auditory cues. Previous works reveal desirable properties of condensed instructions, topological relationships, being immersive, forcing to actively engage in the way-finding task and being in the context of game. Furthermore, they highlight that spatial auditory icons and callouts can aid spatial understanding. In this sense, the researchers conducted audio map system with several interactive function and many techniques to reduce confusing of sound. Then they evaluated the efficacy through conducting the game of collecting coins along the way with 4 levels. By using multiple one-way ANOVAs, the way-finding index (experience of navigating) and sonification index (impact of the auditory cues) showed the efficacy. Besides, the visual trace of participants also showed the same result.
 I often like to think in the way converting something visual to auditory one or vice versa. I know the potential of this method, so I'm optimistic about this attempt to replace vision with sound.
