Abstract
This paper describes a study aimed at developing and applying a method for comparing the user experience (UX) of virtual reality (VR) systems, in order to identify aspects that differentiate VR systems from a user perspective as well as aspects that users consider important when selecting a VR system. A within-subjects study was conducted, in which twelve participants played a VR game using four different VR systems (i.e., VR headsets and hand controllers). The UX was evaluated through semi-structured interviews and questionnaires. Headset comfort, fit, and perceived image quality as well as unrestricted mobility (i.e., untethered headsets) were identified as important aspects for the UX. Hand controllers that allowed more natural interaction were generally preferred. Image sharpness and headset comfort were considered the most important aspects for selecting a VR system. The study demonstrated that the method can be applied and generate insights into the UX of VR systems.
