Problems Found in AR Device Application on Blind
- Poor ergonomics : Users felt that the HoloLens 1 headset was heavy and uncomfortable, as well as worsening their sense of air currents and echoes that normally let them sense their surroundings. Several asked for a headband-style device that would not cover their face.
- Unintuitive gaze control: Several of our blind users simply were not used to pointing their head towards areas they wanted more information about, and had to be reminded to do so. This also became a problem for pointing the device towards text to be identified, as combined with the weight of the headset, users often let their head droop towards the ground.
- Low speed of mapping and text recognition: The several second delays in mapping and text processing required a controlled, pre-scanned environment and repeatedly frustrated our users, especially when they failed to identify text on the first scan.
