Usability Study of a Novel Tool: The Virtual Cafeteria in Nutrition Education



      This study aimed to evaluate the usability of the virtual cafeteria (VC) and determine its suitability for further studies in portion size education and rehabilitation of nutrition.


      The study was conducted with 73 participants (aged 18–40 years). The VC, where the participants performed the task of assembling a meal, was created as a virtual reality simulation of a buffet-style cafeteria (94 food and 10 beverage items). The participants were asked to complete the System Usability Scale, which regards ≥70 points as acceptable, and to give comments about the VC.


      The mean System Usability Scale score was 79.4 ± 12.71 (range, 22.2–97.2). Approximately 68% of the participants described positive qualities for the VC. The participants with technical background reported the VC as more usable (96%) than the others (74%) (χ2 = 5,378; df = 1, P = 0.025).

      Conclusions and Implications

      Offered as a novel tool for education and rehabilitation of nutrition, the VC was confirmed to feature good usability.
