我们描述的工作目标是设计一个用户界面，即使是新手，文盲用户也完全不需要任何人的干预。我们的无文本用户界面是基于与三个班加罗尔贫民窟的文盲家庭劳工社区合作进行的许多小时的民族志设计。一个民族志设计过程被用来了解什么样的应用程序主题会感兴趣，他们如何响应计算技术，以及他们如何反应特定的UI元素。我们使用这些原则构建了两个应用程序，一个用于家政工人的求职，另一个用于导航城市的通用地图。最终的设计基于我们在设计过程中获得的关键经验教训。本文介绍了设计过程中，设计原则的演变过程中，最终的应用程序设计，并从最初的用户测试结果。我们的研究结果证实了以前的工作，强调需要半抽象的图形和语音反馈，但我们还发现，文盲用户的设计，以前被忽视的一些方面（如一致的帮助功能）。结果还表明，无文本的设计是强烈首选的标准文本为基础的界面，由社区，我们的地址，他们有可能带来甚至复杂的计算机功能的用户谁是无法阅读
We describe work toward the goal of a user interface designed such that even novice, illiterate users require absolutely no intervention from anyone at all to use. Our text-free user interface is based on many hours of ethnographic design conducted in collaboration with a community of illiterate domestic labourers in three Bangalore slums. An ethnographic design process was used to understand what kind of application subjects would be interested in, how they respond to computing technology, and how they react to specific UI elements. We built two applications using these principles, one for job search for domestic labourers, and another for a generic map that could be used for navigating a city. The resulting designs are based on key lessons that we gained through the design process. The paper describes the design process, the design principles which evolved out of the process, the final application design, and results from initial user testing. Our results confirm previous work that emphasizes the need for semi-abstracted graphics and voice feedback, but we additionally find that some aspects of design for illiterate users that have been previously overlooked (such as a consistent help feature). Results also show that the text-free designs are strongly preferred over standard text-based interfaces by the communities which we address, and that they are potentially able to bring even complex computer functions within the reach of users who are unable to read
