With the growing demand for the use and applications of modern extended reality (XR) technology, recent studies have investigated the user experience of augmented reality (AR) and virtual reality (VR) for gaming purposes. Despite AR’s and VR’s pervasiveness in the video game industry, research studies into the effects of mixed reality (MR) on video game experience are scarce. Consequently, this study examines the impact of MR on video game satisfaction. Participants will play the same strategy video game across two gaming platforms, including an MR head-mounted display, the Magic Leap 1, and a mobile device. A short version of the psychometrically validated Game User Experience Satisfaction Scale (GUESS-18), which consists of nine constructs, and the Enjoyment Scale (ENJOY) will be used to measure video game satisfaction and enjoyment, respectively. Furthermore, we will then analyze the correlation between satisfaction, enjoyment, and performance in each platform. Results will demonstrate the impact of MR for gameplay on user satisfaction and performance when compared to mobile gameplay. Additionally, the potential of future video games in mixed reality environments will be discussed.
