Assured Information for Hearing Impaired People using Electronic Information Boards

我们进行了三项调查，以确定电子信息板的易读性听力受损（HI）的人。首先，我们收集了HI学生对电子信息板的意见。38%的学生表示，如果通过缩短滚动文本来加快显示周期，可以提高可用性。第二，我们收集了关于车站运行图混乱的信息，并对其进行了修改，使其只包含有效传达信息的短语，平均缩短了约35%。最后，我们进行了一项实验，HI学生和听力学生测量他们的注视点的运动，因为他们默默地阅读滚动的文本，并评估他们的理解水平。结果，HI学生的注视点被拖得更快，对文本含义的正确反应率略低于听力学生。

We conducted three investigations to determine the legibility of electronic information boards for hearing impaired (HI) people. First, we collected opinions from HI students about electronic information boards. 38% of the students' descriptions suggested that usability could be improved if the display cycles were accelerated by shortening the scrolling texts. Second, we collected messages about the disorder of the operation diagrams displayed at stations and revised them so that they only contained phrases that are effective at conveying information, reducing their length by about 35% on an average. Finally, we conducted an experiment with both HI students and hearing students to measure the movement of their gaze points as they silently read the scrolling texts and to assess their comprehension levels. As a result, HI students had their gaze points dragged more rapidly and showed a slightly lower rate of correct responses regarding the meaning of the text than the hearing students.
