Usability Evaluation of VR (Virtual Reality) Intravenous Infusion Pump Training Contents for Nursing College Students

Purpose : This study aimed to evaluate system usability, user response, and simulator sickness of virtual reality (VR) intravenous infusion pump training contents among nursing college students. Methods : The design of this study was descriptive research and the subjects of the convenience sample study were third and fourth-year nursing students who had never actually used an infusion pump before. Data were collected from October 11 to November 25 in 2022. Forty-five students tested a VR infusion pump content which included 7 scenarios each taking 2 to 3 minutes to complete. Data were collected using the System Usability Scale (SUS), a User Reaction Survey (URS), and a Simulator Sickness Questionnaire (SSQ). Results : Results revealed that the system usability score was 68.3 which indicated a ‘B’ grade, ‘excellent’ adjective rating and ‘marginal’ acceptability range. User reaction score was 3.83 ± 0.47 points out of 5-point scale and Simulator sickness score was 2.70 ± 1.26 points out of 7-point scale. Conclusion : VR intravenous infusion pumps training contents may be a effective way to promote mastery learning and retention.
