On utilizing gaze behavior to predict movement transitions during natural human walking on different terrains
Fig 5
Gaze and gait parameters for stairs transitions as a function of steps to/from walk mode transition.
Left row: Deviation of eye and head pitch angles from the baseline for transitions involving stairs. Right row: Deviations of the normalized step length and period from their baselines for transitions involving stairs. The error bars indicate the 95 % confidence interval of the non-parametric bootstrap distribution. Stars indicate statistically significant differences with a significance level . The transition is marked by a dotted line. The shaded area between 1 step before and after the transition is subject to ambiguities in the walk mode labeling.
