    Virtual Reality in Health Care Education: A Study about the Effects of Presence on Acceptance and Knowledge Improvement among Health Care Students
    (DELFI 2020 – Die 18. Fachtagung Bildungstechnologien der Gesellschaft für Informatik e.V., 2020) Plotzky, Christian; Lindwedel-Reime, Ulrike; Bejan, Alexander; König, Peter; Kunze, Christophe
    With an ever-increasing need of skilled healthcare workers, efficient learning methods like Virtual Reality are becoming increasingly important. A VR simulation for endotracheal suction intervention was developed and tested. The aim of this pilot study is to examine the VR simulation’s acceptance and knowledge improvement. Furthermore, the effect of presence on acceptance and knowledge improvement was investigated. A total of 51 students participated in the pilot study, using pre-post-test design. A modified Unified Theory of Acceptance and Use of Technology (UTAUT) and Igroup Presence Questionnaire (IPQ) were used. Correlation and regression analysis were performed. Pre- and post-tests showed a significant knowledge improvement (p<0.001). Correlation between presence and behavioural intention was highly positive (r=0.52, p<0.001). Performance and effort expectancy are dominant in effect on behavioural intention of using VR learning simulation. The results indicate that a simulation, which conveys a higher sense of presence, is more likely to be accepted.

    Virtual Reality in Healthcare Skills Training: The Effects of Presence on Acceptance and Increase of Knowledge
    (i-com: Vol. 20, No. 1, 2021) Plotzky, Christian; Lindwedel, Ulrike; Bejan, Alexander; König, Peter; Kunze, Christophe
    With an ever-increasing need of skilled healthcare workers, efficient learning methods like Virtual Reality (VR) are becoming increasingly important. We developed and tested a VR simulation for endotracheal suctioning. The aim of this pilot study was to examine the VR simulation’s acceptance and increase of knowledge among participants. Furthermore, the effects of presence on acceptance and increase of knowledge were investigated. A total of 51 students participated in the pilot study, using a quasi-experimental pre-post-test design. A modified Unified Theory of Acceptance and Use of Technology (UTAUT) and the Igroup Presence Questionnaire (IPQ) were used. Correlation and regression analyses were performed. Pre- and post-tests showed a significant increase of knowledge (p < 0.001). The correlation between presence and behavioural intention was highly positive (r = 0.52, p < 0.001). Performance and effort expectancy are dominant effects on behavioural intention of using the VR simulation as an educational tool. The results indicate that a simulation which conveys a higher sense of presence is more likely to be accepted by learners. Regarding outcomes of presence on increase of knowledge, we found no significant correlation. Based on our study, we propose a design for a future mixed reality simulation with haptic elements and a plan on how to assess skills improvement.

    xR Skills Lab – Mixed Reality Ansätze zum Skills-Training in gesundheitsbezogenen Studiengängen - Lernmodul zum Erlernen von endotrachealem Absaugen
    (Wettbewerbsband AVRiL 2021, 2021) Plotzky, Christian; Loessl, Barbara; Lindwedel, Ulrike; König, Peter; Kunze, Christophe
    Das praktische Training von Fertigkeiten (Skills) spielt in der Pflegeausbildung eine bedeutende Rolle. Angesichts der angespannten Personallage wird aber die Praxisanleitung von Auszubildenden zunehmend zu einer Belastung im klinischen Alltag. Virtual Reality (VR) gestütztes Training könnte eine Alternative bieten, denn es kann orts- und zeitunabhängig durchgeführt werden und ist mit vergleichsweise geringen Kosten verbunden. Unsere Studie evaluiert die Effektivität von VR-Simulationen zum Erlernen des endotrachealen Absaugens im Vergleich zu einem traditionellen Lernmodul. Dazu entwickelten wir zwei VR Simulationen. Eine Variante zeigt zusätzlich die Tätigkeit in der Erstperson-Perspektive mittels Videos bzw. Animationen der Hände. Die Nutzung von digitalen Technologien ermöglicht, Skills vorab zu erlernen und zu üben, was die Anleitung in der Praxis sowohl entlasten als auch ergänzen kann. Unter- und Fehlversorgungen und Komplikationen werden vermindert oder vermieden, was zu einer höheren Versorgungsqualität führt.
