| 摘 要： | 在屏幕放大镜的不同工作模式下,72名老年参试者完成了16个词语搜索任务.统计结果表明,老年用户在使用重叠模式的放大镜时,绩效高于使用平行模式时;使用黄色背景的放大镜时,绩效高于使用无背景色的放大镜时;当文本密度较低时,放大镜以双工模式呈现信息时,用户具有较高的绩效;当文本密度较高时,没有发现用户绩效之间存在显著的差异.根据以上发现,对屏幕放大镜的设计提出了一些建议.

| Abstract: | Under different working modes of a screen magnifier, seventy-two older participants finished 16 word search tasks. The analysis results indicates that. when using a screen magnifier with overlapping mode, the user performed better than using the one with parallel mode; when using a screen magnifier in yellow background, the user performed better than using a screen magnifier without background color; for the lower text density, the mono output mode was better than the dual output mode, while for the higher text density, no difference was found between such two modes. Based on the findings, some recommendations were made for screen magnifier design. |
