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.
本研究评估了一个基于网络的听觉地图原型，该原型是利用音频游戏中的惯例构建的，并展示了参与者使用该原型执行的一系列任务的结果。与大多数研究不同，该原型允许参与者使用自己的电脑和屏幕阅读器，而大多数研究将使用限制在单一平台和自动语音功能（默认提供语音）上。任务得出了三个主要结果：界面极其易于学习和导航，参与者都有独特的导航风格，并且更喜欢使用自己的屏幕阅读器，以及参与者需要使理解和回答有关空间属性及关系的问题变得更容易的用户界面功能。参与者给出的美国国家航空航天局任务负荷指数的平均任务负荷评分为39，对于实际使用该原型进行物理导航的信心水平为46/100。
