QUEST 2.0 subjective ratings of AAT usability: A The mean QUEST ratings of both respondent groups (PIL; n = 35, TL; n = 46) are shown per discipline, as well as overall (mean across all disciplines). The QUEST rating scale ranges from 0 = Not satisfied at all, to 5 = Completely satisfied. Significant differences were found for the EXO (p = 0.014) and WHL (p = 0.049) disciplines, as well as the overall mean (p = 0.019). B The QUEST mean of each individual response is shown for both respondent groups. For all teams with at least one PIL and TL response, an intra-team line is drawn to highlight differences of opinion about the same AAT device (p = 0.019). For all teams with multiple responses (e.g., two TL for team), the overall mean per subgroup is shown
