1. User Profile
The first piece of information that VR systems need to gather is the user’s profile. This includes their age, height, weight, and other physical characteristics, as well as their previous experience with VR technology. By understanding the user’s profile, VR systems can adjust the visual and audio elements to create a more personalized experience.
2. Eye Tracking
Eye tracking is another critical piece of data that VR systems need to gather. By tracking the user’s eye movements, VR systems can create a more immersive experience by adjusting the visual elements to match where the user is looking. For example, if the user is looking at an object in the virtual world, the VR system may adjust the brightness and contrast of that object to make it more realistic.
3. Movement Tracking
Movement tracking is another essential piece of data that VR systems need to gather. By tracking the user’s movements, VR systems can create a more realistic experience by adjusting the visual and audio elements to match the user’s actions. For example, if the user is standing up, the VR system may adjust the height of objects in the virtual world to make them more realistic.
4. Surroundings
VR systems also need to gather information about the user’s surroundings. This includes the physical environment, such as the size and shape of the room, as well as any other objects or people that are present. By understanding the user’s surroundings, VR systems can create a more realistic environment by adjusting the visual and audio elements to match the real-world environment. For example, if the user is in a noisy room, the VR system may adjust the audio levels to make it more realistic.
5. User Feedback
User feedback is another critical piece of data that VR systems need to gather. By gathering feedback from users, VR systems can adjust the visual and audio elements to create a more engaging experience. For example, if users find that certain objects in the virtual world are too difficult to interact with, the VR system may adjust those objects to make them easier to interact with.
Case Study: The Development of “Beat Saber”
“Beat Saber” is a popular VR game that uses music as its primary gameplay element. To create an immersive and engaging experience, the developers at Beat Games needed to gather a significant amount of data about the user’s profile, surroundings, and feedback.
For example, to create a more personalized experience, the game adjusts the height and size of objects in the virtual world based on the user’s physical characteristics. It also uses eye tracking to adjust the visual elements to match where the user is looking.
The game also tracks the user’s movements, allowing them to interact with objects in the virtual world in a more realistic way. For example, if the user swings their arms to hit an object in the virtual world, the game adjusts the visual and audio elements to make it feel more realistic.
Finally, the game gathers feedback from users through a variety of means, including surveys and in-game data collection. This feedback is used to adjust the game’s difficulty level and other elements to create a more engaging experience for players.
