A User-Centered Study on Virtual Reality Training Systems’ Design Features

This paper introduces a unique, feature-based methodology for determining the best design features of a Virtual Reality Training System (VRTS). It offers a holistic approach by using a revised Technology Acceptance Questionnaire, which assesses design features from a user's perspective, rather than relying solely on objective measures of training effectiveness. We implemented the methodology in an experimental campaign, which involved simulating manual processes in two VR platforms with different features. Both novice and experienced VR users participated in the study, evaluating design features for perceived usefulness and ease of use. The findings provide insights into improving VRTS design based on user experience, highlighting the potential of our feature-based methodology.
