Researchers asked 12 participants — all of which being legally blind — to test their HoloLens prototype by walking both up and downstairs using the prototype in their preferred settings. Across participants, walking time had a significant increase when walking downstairs with the HoloLens and no significant increase or decrease when walking upstairs with the HoloLens. Participants reported feeling more psychologically secure when using the HoloLens to navigate stairs, though at a smaller rate than with the AR projection-based prototype.
