许多项目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我们认为广泛部署的系统所必需的三个因素，以提供丰富的环境体验：在商品设备上实现，使用预先存在的全球兴趣点（POI）数据库，以及呈现环境的方法，这种方法优于简单的语音文本回放。我们的“现场音频服务”（ISAS）应用程序响应了这些需求，允许用户在没有特定目的地的情况下探索城市区域。我们描述了其实现的技术方面、用户需求、界面设计、安全问题、POI数据源问题，以及使系统在更广泛的基础上实用的进一步需求。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.
