Animated Icons as an Assistant During Interaction Between a Graphical User Interface and the Legally Blind/Partially Sighted

这个项目解决了法律盲人与利用图形用户界面（gui）的信息系统交互的需求。本研究的重点是描述性动画图标的研究，并开发一个框架，使GUI开发人员能够更有效地解决法律盲人在设计界面布局和功能时使用的图标识别过程。在最初的研究中，pi将为视觉灵敏度在20/200到20/800范围内的个体确定动画和非动画图标的最佳尺寸。这项研究将产生一种启发式方法，使他们能够描述合法失明的计算机用户与GUI交互的方法。然后，pi将设计一个动画图标库，这将作为开发面向法律盲人的gui的基础。将使用该技术开发和评估一个概念验证应用程序，以便提供有关如何将动画图标正确集成到GUI中以实现既定目标的信息。pi期望作为该项目的一部分开发的图标库适用于广泛的应用领域，并且在gui中使用适当大小的描述性动画图标将帮助越来越多的法律盲人以电子形式访问信息。

This project addresses the needs of the legally blind to interact with information systems that utilize graphical user interfaces (GUIs). The research focuses on the study of descriptive animated icons and the development of a framework to enable GUI developers to more effectively address the icon recognition process utilized by the legally blind when designing interface layout and functionality. In an initial study the PIs will determine optimal sizes for icons, animated as well as non-animated, that are perceived by individuals whose visual acuity is in the range of 20/200 to 20/800. This study will result in a heuristic that will allow them to describe the means by which legally blind computer users interact with a GUI. The PIs will then design a library of animated icons which will serve as a foundation in the development of GUIs that are accessible to the legally blind. A proof-of-concept application will be developed and evaluated using this technology, in order to provide information on how to properly integrate animated icons into a GUI to achieve the stated goals. The PIs expect the icon library developed as part of this project to be applicable to a wide variety of application domains, and that the use of properly sized, descriptive animated icons in GUIs will help the increasing legally blind population to access information in electronic form.
