摘要

低视力读者依赖放大率，但放大率会减少可浏览的文本量，并阻碍文本导航。在这项研究中，我们评估了字体变化——字母间距、字母宽度和字母加粗——对低视力阅读的影响。我们测试了20名患有年龄相关性黄斑变性（AMD）的低视力患者，并使用了Radner阅读图，该图测量了阅读敏锐度（logRAD）、最大阅读速度和临界打印尺寸。研究结果表明，在临界字体大小附近，字母间距和字母宽度对阅读敏锐度的影响很小，但可以测量。

Increased letter spacing and greater letter width improve reading acuity in low vision readers

Low vision readers depend on magnification, but magnification reduces the amount of text that can be overviewed and hampers text navigation. In this study, we evaluate the effects that font variations letter spacing, letter width, and letter boldness have on low vision reading. We tested 20 low-vision patients with age-related macular degeneration (AMD) and used the Radner Reading Chart, which measures reading acuity (logRAD), maximum reading speed, and critical print size. The results demonstrated a small, but measurable effect of letter spacing and letter width on reading acuity near critical font sizes.

期刊介绍： Information Design Journal (IDJ) is a peer reviewed international journal that bridges the gap between research and practice in information design. IDJ is a platform for discussing and improving the design, usability, and overall effectiveness of ‘content put into form’ — of verbal and visual messages shaped to meet the needs of particular audiences. IDJ offers a forum for sharing ideas about the verbal, visual, and typographic design of print and online documents, multimedia presentations, illustrations, signage, interfaces, maps, quantitative displays, websites, and new media. IDJ brings together ways of thinking about creating effective communications for use in contexts such as workplaces, hospitals, airports, banks, schools, or government agencies.
