This study evaluated a web-based auditory map prototype built utilizing conventions found in audio games and presents findings from a set of tasks participants performed with the prototype. The prototype allowed participants to use their own computer and screen reader, contrary to most studies, which restrict use to a single platform and a self-voicing feature (providing a voice that talks by default). There were three major findings from the tasks: the interface was extremely easy to learn and navigate, participants all had unique navigational styles and preferred using their own screen reader, and participants needed user interface features that made it easier to understand and answer questions about spatial properties and relationships. Participants gave an average task load score of 39 from the NASA Task Load Index and gave a confidence level of 46/100 for actually using the prototype to physically navigate.
