Fig. 3: AR Visual Mobility task methods.

From: Seeing other perspectives: evaluating the use of virtual and augmented reality to simulate visual impairments (OpenVisSim)

Fig. 3

a Hardware: The modified HTC Vive headset, with ZEDmini stereoscopic cameras and integrated Tobii eye-tracking. b Task: Screenshots from four simultaneous camera feeds, recorded during a typical trial of the Visual Mobility task. The participant’s task was to trace an approximately ‘s’ shaped route (green line) from the start point [S] to the finish point [F]. The configuration of the blue partitions, and the exact location of the two foam obstacles (shown in bottom left panel), was varied randomly between trials. An experimenter followed the observer at a safe-distance in case of any trips or accidents. See Bainbridge et al.59 for further details. c The simulated VFL conditions were the same as in the main experiment (Fig. 2). See Supplementary Video 3 for an example trial.
