Augmented Reality (AR) has introduced new forms of interaction and presentation in mobile applications. Mobile games have also taken the advantages of this technology to implement novel techniques for interaction between players and game objects. This paper aims to study the effect of AR technology on the sense of immersion and quality of experience in mobile games. In particular, we compare Virtual Reality (VR) camera with AR camera in terms of enhancing the sense of immersion and quality of experience in mobile games. A comprehensive user study is performed to find if there is a significant difference in the sense of immersion between the players using these different cameras. We also analyze how the quality of experience is affected by this parameter.
