Enhanced Player Interaction Using Motion Controllers for First-Person Shooting Games in Virtual Reality

The main purpose of virtual reality (VR) is to enhance realism and the player experience. To do this, we focus on VR interaction design methods, analyze the existing interaction solutions including both accurate and rough interaction methods, and propose a new method for creating stable and realistic player interactions in a first-person shooter (FPS) game prototype. In this research, we design and modify the existing mapping methods between physical and virtual worlds, and create interfaces such that physical devices correspond to shooting tools in virtual reality. Moreover, we propose and design prototypes of universal interactions that can be implemented in a simple and straightforward way. Proposed interactions allow the player to perform actions similar to those of real shooting, using both hands such as firing, reloading, attaching and grabbing objects. In addition, we develop a gun template with haptic feedback, and a visual collision guide that can optionally be enabled. Then, we evaluate and compare our methods with the existing solutions. We then use these in a VR FPS game prototype and conduct a user study with participants, and the resulting user study proves that the proposed method is more stable, player-friendly and realistic.
