 \figref{results_questions} presents the questionnaire results for each visual hand augmentation.
 Friedman tests indicated that all questions had statistically significant differences (\pinf{0.001}).
-Pairwise Wilcoxon signed-rank tests with Holm-Bonferroni adjustment were then used each question results:
