A post-study questionnaire with Likert-scale items covered tutor effectiveness, satisfaction with 3D AR content, and perceived effectiveness versus manuals and videos. The article reports "None of the ratings were significantly different between the two groups"; 81% rated agreement six or higher that the tutor taught the procedure.
