Measuring Collision Anxiety in XR Exergames

Extended Reality (XR) applications have become increasingly relevant due to technical advances, but also have their own challenges regarding the user's real-world orientation. We propose a novel definition and a not yet validated questionnaire for the feeling of disorientation and fear of colliding with real objects in XR, called Collision Anviety (CA). Participants (N = 37) played an AR and VR version of a game with results suggesting that while an AR game can provide a similar player experience compared to its VR equivalent, differences regarding CA exist.
