Results for obstacle avoidance task comparing device on (blue) versus device off (red). (A) Success rate (%) for verbally indicating object location on approach. (B) Walking speed for each trial, expressed as percentage of preferred walking speed (PPWS). (C) Collision rate (%) for each trial. (D) Percent of trials with zero collisions or contact. The height of the bar is each participant’s average of 10 trials at the final time-point. Error bars denote the range of average scores across all time-points. Solid circles denote the median of average scores across all time-points. P values of within-participant comparisons are shown; ∗∗∗P < 0.001; ∗∗P < 0.01; ∗P < 0.05.
