Abstract
Academic research on the psychological effects of mixed reality (MR) vocational training is scarce. Understanding this use is still being determined. This study analysed the degree of fatigue in different domains after MR multi-victim incident resolution training, taking this into account to improve the user experience and the learning procedure. This study valued the fatigue of participants of the MR six field trials of the MED1stMR project in the following countries: Austria, Belgium, Germany, Greece, Spain and Sweden. There were 260 participants (N), of whom 173 were male and 87 female. The mean age of the participants was 40.16 years (M). The mean professional experience in emergency medicine was 12.28 years. We used a fatigue scale validated for application in mixed-reality professional training. The fatigue questionnaire addressed five fatigue domains and was answered after MR training. The MR fatigue scale applied to Medical First Responders (MFRs) showed and detected relevant fatigue dimensions: General, Social, Emotional, Emotional, Visual, and Motivational fatigue. Both general fatigue and visual fatigue had the most significant effects. Among the professions analysed in the training, the medical profession suffered more significant visual fatigue than the rest of the professionals.
