Individual’s 95% confidence intervals of crossing heights of real and holographic obstacle-avoidance trials of Experiment 2 for participants identified in Experiment 1 as those with extreme lead-foot margins or without raising the trail foot.

* Individual’s difference in crossing height between real obstacle avoidance trials (95% confidence intervals based on all 30 trials) and the baseline holographic obstacle-avoidance trials (95% confidence interval based on the five baseline trials). ** Individual’s difference in holographic obstacle crossing heights between the baseline trials and the feedback and/or follow-up trials. *** The number between parentheses indicates the first block of five consecutive feedback trials for which the 95% confidence interval deviated from that of the baseline trials (with 14 indicating the final block of five trials of mixed-reality video feedback).
