Developing research-based guidelines for improving access to small-screen displays

This is a report on the initial phase of an effort to develop research-based guidelines to improve accessibility of small-screen visual displays for persons who are visually impaired. Contrast modulation was measured in a test group of 12 home blood pressure monitors (HBPMs) that use small-screen visual displays. Next steps include obtaining subjects' contrast sensitivity using an interactive, software driven display and demonstrating techniques for measuring font size, luminance, glare, and hue. In the final phase of the project, a clinical study will be conducted to define optimal small-screen display parameters for visually impaired subjects.

这是一份关于一项工作初始阶段的报告，该工作旨在制定基于研究的指南，以提高视力受损者对小屏幕视觉显示器的可访问性。对12台使用小屏幕视觉显示器的家用血压监测仪（HBPM）的测试组进行了对比度调制测量。接下来的步骤包括使用交互式软件驱动的显示器获取受试者的对比敏感度，并展示测量字体大小、亮度、眩光和色调的技术。在该项目的最后阶段，将进行一项临床研究，以便为视力受损的受试者确定最佳的小屏幕显示参数。
