Abstract	Good visibility is essential to maintaining QoL (Quality of Life). Unfortunately, the world is rapidly aging, and aging degrades vision performance. In order to create future home/campus environments, we clarify the basic attributes of visibility that are needed to support low vision, or vision-impaired people. In an experiment, 30 subjects wear goggles simulating visual disturbances (constriction of the visual field and wall-eye) to determine the maximum distance that permitted successful recognition between the subject and a sign. The signs used here have 5 different patterns, from a simple humanoid to a humanoid plus blinking bricks. Subjects' comments on visibility are also gathered after the distance experiment. The result implies the size of sign needed for vision impaired people in home/campus environments.
