VR gaming experiences emphasize sensations such as “presence” and “immersion,” which has led to the significant underutilization of the bird’s-eye view in VR games. Additionally, due to the lack of thorough research and practical exploration into VR interaction methods from a bird’s-eye perspective, this widely used viewpoint in traditional gaming platforms has been hindered in its evolution within the VR medium. This study aims to explore the potential applications of the bird’s-eye view in VR by focusing on game interaction interface design.

　　This research centers on the interaction interface design for bird’s-eye view VR games. Using a literature review approach, it organizes relevant theoretical frameworks. Through an in-depth discussion of VR interaction interfaces and bird’s-eye view VR interaction technologies, key evaluation dimensions and design criteria are distilled, forming a solid theoretical foundation. Based on this, four design principles are proposed: prioritizing direct actions, adhering to embodied experience, favoring recognition over recall, and maintaining logical consistency.

　　Subsequently, these principles were applied in practice, with the RTT (Real-Time Tactics) game genre chosen as the research subject. By analyzing existing game cases, typical interaction behaviors in bird’s-eye view VR games were identified. A new VR interaction interface was designed based on the proposed principles, and a prototype was developed. Furthermore, the original case game’s interaction interface was migrated to the VR platform as a control for subsequent comparative experiments, providing material for reference. The entire design and development process was meticulously documented to serve as a guide for peers. To validate the effectiveness of the newly proposed design principles, a rigorous experimental procedure was designed. Within-group experiments compared the performance of the VR interaction interface designed according to the new principles with that of traditional Gamepad interfaces transplanted into the VR environment. A mixed-methods approach combining quantitative data and qualitative analysis was employed to thoroughly investigate the practical impact of the design principles.

　　According to the experimental results, applying the bird’s-eye view VR game interaction interface design principles proposed in this study can yield RTT game interaction methods better suited to the VR medium than traditional game controllers. This demonstrates that by optimizing interaction methods, the application potential of the bird’s-eye view in VR environments can be fully realized. Finally, through comprehensive analysis of the experimental results, the study concludes the practical value of the proposed design principles and identifies potential areas for improvement, such as incorporating seated experiences into research and introducing gesture-based interactions.
