许多项目已经研究了盲人社区的辅助导航技术，解决了从界面设计到感官替代的挑战。然而，这些都没有成功地集成了我们认为是一个广泛部署的系统，提供了一个人的环境的丰富体验所必需的三个因素：在商品设备上的实现，使用预先存在的全球兴趣点（POI）数据库，以及渲染的环境是优于一个朴素的播放口语文本的手段上级。我们的“现场音频服务”（ISAS）应用程序响应了这些需求，允许用户探索城市地区，而不必考虑特定的目的地。我们描述了它的实现，用户需求，界面设计，安全问题，POI数据源问题，并进一步要求，使系统实用的更广泛的基础上的技术方面。还讨论了盲人用户的初步定性反馈。
Numerous projects have investigated assistive navigation technologies for the blind community, tackling challenges ranging from interface design to sensory substitution. However, none of these have successfully integrated what we consider to be the three factors necessary for a widely deployable system that delivers a rich experience of one’s environment: implementation on a commodity device, use of a pre-existing worldwide point of interest (POI) database, and a means of rendering the environment that is superior to a naive playback of spoken text. Our “In Situ Audio Services” (ISAS) application responds to these needs, allowing users to explore an urban area without necessarily having a particular destination in mind. We describe the technical aspects of its implementation, user requirements, interface design, safety concerns, POI data source issues, and further requirements to make the system practical on a wider basis. Initial qualitative feedback from blind users is also discussed.
