Usability of a virtual reality resource for oscilloscope teaching expert assessment

Abtract

Virtual reality is part of the set of haptic technologies that allow the user to interact with an artificial scenario, different from the real world but very similar to it. Within the field of education, it promotes active and dynamic learning with immersive experiences. The goal of this study was to assess the usability of an object in VR format for oscilloscope instruction. We created a virtual physics lab environment in version 1.0. The methodology has a quantitative, descriptive approach. Brooke (1996) designed the System Usability Scale (SUS), which collected data from experts in both technology and physics, totaling 42 participants. We obtained Cronbach's alpha and McDonald’s omega indexes with values of 0.924 and 0.901, respectively. The results reveal that the virtual reality (VR) resource received an assessment of 72.58, corresponding to a percentile between 65 and 69, across 500 previous studies by various authors on the SUS. This indicates that the created object has a good acceptance range, being valued as very good and suitable for use in teaching.
