Designing AR Visualizations to Facilitate Stair Navigation for People with Low Vision
summary
A projection-based system called StairLight uses a depth sensor and projector (Wizard-of-Oz stationary setup in the study) to highlight stair edges with thicker yellow markings on first/last steps and thinner or blue highlights on middle steps, plus attention patterns like a flashing edge and a moving vertical zebra. Evaluated with 12 people with low vision, it speeds walking, raises psychological security (mean 6.6/7), reduces cane/railing use, but requires caution because computer-vision mistakes can still create safety risks.
