Interface design is undoubtedly important and dictates how a user will interact. However, in game design, interfaces are also crucial to player immersion and world-building. The four main classes of interfaces (diegetic, non-diegetic, meta, spatial) in game design work together to ensure that every interaction is seamless, immersive, and reinforces the game's environment. To understand these different types of game interfaces and their roles in immersion, I have collected innovative game UIs and designed an interactive website called the Gaming Interfaces Repository. This site hosts examples for each of the four categories, tagged with interface and game filters. It is designed with interactions and spatial depth to create a sense of an immersive environment, similar to that of a video game. With two contrasting visual galleries, an index, and a personal collection, the website allows the user to learn about the distinct interfaces in game design from multiple approaches. Through this interactive and immersive design, the Gaming Interfaces Repository aims to raise awareness of the significance of interface design in gaming and serve as a valuable resource for both designers and gamers.
