ADJUSTABLE TYPOGRAPHY FOR OLDER VISION-IMPAIRED READERS

描述：(摘自调查人员的摘要)最 数量庞大且数量不断增加的 患有视力障碍的老年人阅读能力下降。 这进而降低了独立性、工作效率和隐私，并限制了 智力刺激的机会。当许多长辈还在 避开电脑和其他电子设备，老一辈人 越来越多地由对此感到满意的个人组成，实际上 他们的大部分阅读都依赖于电脑显示器。从长远来看 本研究的目标是专门开发一种软件产品 专为较老的视力障碍阅读器设计，用户可以定制 连续调整的文本显示的排版 字母间距、字母笔划宽度、字母长宽比、 和衬线大小，以及点大小，以获得最佳易读性。第一阶段 研究将通过开发一种 可变参数字体，评估对象间和对象内 参数调整、阅读敏锐度和阅读速度的可变性， 由一组患有功能性阅读障碍的人组成的样本 由一系列视觉障碍引起的。 建议的商业应用： 建议的商业应用程序不可用。

DESCRIPTION: (taken from the investigator's abstract) The most significant limitation experienced by the large and growing number of older individuals with visual impairment is reduced ability to read. This in turn reduces independence, productivity, and privacy, and limits opportunities for intellectual stimulation. While many elders still shun computers and other electronic devices, the older generation is increasingly made up of individuals who are comfortable with, and indeed depend on computer displays for much of their reading. The long term objective of this research is to develop a software product specifically designed for the older vision-impaired reader that a user can customize the typography of a text display with continuous adjustment of parameters of letter spacing, letter stroke width, letter aspect ratio, and serif size, as well as point size, for best legibility. Phase I research will test the feasibility of the concept by developing a variable parameter font, and assessing inter- and intra-subject variability of parameter adjustment, reading acuity and reading speed, by a sample of individuals with functional reading impairments resulting from a range of visual disorders.
