大多数低视力的人都有功能性视力，他们可能更喜欢用他们的视力来获取信息。最近，在头戴式显示器、相机和图像处理技术方面取得了进展，为改善弱视人群的视觉体验创造了机会。本文介绍了一种头戴式视觉增强系统ForeSee，该系统具有五种增强方法：放大、对比度增强、边缘增强、黑白反转和文本提取；有两种显示模式：Full和Window。ForeSee使用户能够实时选择、调整、组合不同的增强方式和显示模式，定制自己的视觉体验。我们通过对19名低视力参与者进行近距离和远距离观看任务的研究来评估ForeSee。我们发现参与者在执行不同的任务时对增强方法和显示模式有不同的偏好。放大增强方法和窗口显示模式是最受欢迎的选择，但大多数参与者认为结合几种方法产生最好的效果。定制系统的能力是使具有各种不同视觉能力的人改善视觉体验的关键。
Most low vision people have functional vision and would likely prefer to use their vision to access information. Recently, there have been advances in head-mounted displays, cameras, and image processing technology that create opportunities to improve the visual experience for low vision people. In this paper, we present ForeSee, a head-mounted vision enhancement system with five enhancement methods: Magnification, Contrast Enhancement, Edge Enhancement, Black/White Reversal, and Text Extraction; in two display modes: Full and Window. ForeSee enables users to customize their visual experience by selecting, adjusting, and combining different enhancement methods and display modes in real time. We evaluated ForeSee by conducting a study with 19 low vision participants who performed near- and far-distance viewing tasks. We found that participants had different preferences for enhancement methods and display modes when performing different tasks. The Magnification Enhancement Method and the Window Display Mode were popular choices, but most participants felt that combining several methods produced the best results. The ability to customize the system was key to enabling people with a variety of different vision abilities to improve their visual experience.
