For a person with low vision, interacting with a smartphone to access information that is critical to their independence and safety, while possible, is slow and tedious. The ultimate goal of this research is to remedy that deficiency by creating technology that enables these users to access information quickly and easily, both at home and on the go. As a concrete and challenging first step, the work will focus on systems to enable seniors with low vision to plan and execute urban navigation tasks. If successful, members of this large and growing target community will be empowered to perform a key activity of daily living with more confidence and independence. Project outcomes will advance the state of the art in accessibility research more broadly, by laying the foundation for a new paradigm of accessible interaction via low-cost mainstream devices.To these ends, the research will involve a number of phases: (1) documenting the navigation and mobility patterns and challenges facing members of the target user community; (2) the design and implementation of a desktop system that produces "optimal" routes based on feature accessibility along a given route; (3) the design and implementation of a smartphone navigation application that will provide accessible guidance including accessible maps; and (4) evaluation of the smartphone application in the field with target users. Achieving these goals will require an interdisciplinary effort that draws on expertise in a diverse set of fields, including accessibility, interaction techniques, information processing, and machine learning.

对于一个有低视力的人来说，与智能手机互动以访问对独立性和安全至关重要的信息，尽管可能是缓慢而乏味的。 这项研究的最终目的是通过创建使这些用户能够在家中和旅途中快速，轻松地访问信息的技术来解决这种不足。 作为一项具体且富有挑战性的第一步，这项工作将集中在系统上，以使具有低视力的老年人计划和执行城市导航任务。 如果成功的话，这个大型目标社区的成员将有权以更有信心和独立性进行日常生活的关键活动。 项目成果将通过低成本主流设备为新的可访问互动范式奠定基础，从而更广泛地推进最广泛的可访问性研究，从而提高了最广泛的研究。在这些目的中，该研究将涉及许多阶段：（1）记录导航和移动性模式以及目标用户社区的成员面临的导航和挑战； （2）台式系统的设计和实现，该桌面系统基于沿特定路线的功能可访问性生成“最佳”路由； （3）智能手机导航应用程序的设计和实施，该应用程序将提供可访问的指南，包括可访问地图； （4）与目标用户在现场中评估智能手机应用程序。 实现这些目标将需要跨学科的努力，以借鉴各种领域的专业知识，包括可访问性，交互技术，信息处理和机器学习。
