Researchers asked 12 participants — 11 of which being legally blind — to test their AR prototype by walking both up and downstairs using the prototype in their preferred settings. Overall, participants showed a 6.42% decrease in navigation time when going downstairs and a 5.78% decrease in navigation time when going upstairs while using the prototype in their preferred settings. With the prototype, some participants spent less time looking down, some stopped using their feet to feel the stairs, and some no longer held onto the railing while walking. Participants all reported a high level of psychological security when using the prototype.
