对于视力低下的人来说，走楼梯是一个危险的移动挑战，他们的视力障碍还没有达到失明的程度。先前的研究贡献了楼梯导航系统，提供音频或触觉反馈，但视力低下的人有可用的视力，通常不使用非视觉辅助。我们进行了增强现实（AR）可视化的第一次探索，以促进低视力人群的楼梯导航。我们设计了基于投影的AR平台和智能眼镜的可视化，考虑到这些平台的不同特点。对于基于投影的AR，我们设计了直接投影在楼梯上的视觉高光。相比之下，对于具有有限垂直视野的智能眼镜，我们设计了指示用户在楼梯上的位置的可视化，而不直接增强楼梯本身。我们在每个平台上对12名视力低下的人进行了可视化评估，发现基于投影的AR的可视化提高了参与者的步行速度。我们在这两个平台上的设计大大增加了参与者自我报告的心理安全感。
Navigating stairs is a dangerous mobility challenge for people with low vision, who have a visual impairment that falls short of blindness. Prior research contributed systems for stair navigation that provide audio or tactile feedback, but people with low vision have usable vision and don't typically use nonvisual aids. We conducted the first exploration of augmented reality (AR) visualizations to facilitate stair navigation for people with low vision. We designed visualizations for a projection-based AR platform and smartglasses, considering the different characteristics of these platforms. For projection-based AR, we designed visual highlights that are projected directly on the stairs. In contrast, for smartglasses that have a limited vertical field of view, we designed visualizations that indicate the user's position on the stairs, without directly augmenting the stairs themselves. We evaluated our visualizations on each platform with 12 people with low vision, finding that the visualizations for projection-based AR increased participants' walking speed. Our designs on both platforms largely increased participants' self-reported psychological security.
