我们介绍了一项有20名低视力参与者参加的研究，他们在笔记本电脑上操作两种屏幕放大率(镜头和全屏)来阅读两种类型的文档(文本和网页)。我们的目的是对比评估这两种放大方式，并了解视力低下的人是如何使用鼠标控制放大中心的。这些观察结果可能为自动控制放大中心的系统的设计提供参考。我们的结果表明，两种放大模式在阅读成绩或主观偏好上没有显著差异。然而，当使用镜头模式时，我们的参与者采用了更一致和一致的鼠标运动模式，而使用完全模式测量了更长、更频繁的停顿和更短的整体路径长度。使用Full模式对凝视点的分布(由凝视跟踪器测量)的分析表明，当阅读文本文档时，大多数参与者倾向于将感兴趣的区域移动到屏幕的特定区域。
We present a study with 20 participants with low vision who operated two types of screen magnification (lens and full) on a laptop computer to read two types of document (text and web page). Our purposes were to comparatively assess the two magnification modalities, and to obtain some insight into how people with low vision use the mouse to control the center of magnification. These observations may inform the design of systems for the automatic control of the center of magnification. Our results show that there were no significant differences in reading performances or in subjective preferences between the two magnification modes. However, when using the lens mode, our participants adopted more consistent and uniform mouse motion patterns, while longer and more frequent pauses and shorter overall path lengths were measured using the full mode. Analysis of the distribution of gaze points (as measured by a gaze tracker) using the full mode shows that, when reading a text document, most participants preferred to move the area of interest to a specific region of the screen.
