This VR Room project, developed for the Meta Quest 3 using Unity and C#, aims to create an immersive environment where users can freely move, interact with objects, and enjoy a seamless virtual reality experience. The project includes multiple interactive elements, performance-focused design, and visually appealing post-processing effects.

1. Interactive Environment

   • UI Canvas: Utilized world-space canvases for VR menus.
   • Object Interactions: Created XR Grabbable objects, such as a tennis ball, hats that users can pick up or wear, and added a remote to turn on a TV.
   • Sockets: Employed sockets for easy object placement and neat snapping mechanisms.

2. Teleportation & Locomotion

   • Implemented teleportation-based movement to enhance user comfort. Users can choose between continuous movement and teleportation from the settings UI canvas.
   • Incorporated fade transitions to reduce motion sickness during travel.

3. Immersive Design

   • Post-Processing: Applied anti-aliasing and other visual effects for a polished look.
   • Lighting: Mixed real-time and baked lighting to balance realism and performance.

4. Optimization Techniques

   • Performance Tuning: Reduced draw calls, used LODs, and optimized scripts to maintain a stable frame rate. Utilized a static method to further reduce processing overhead.
   • Quest 3 Compatibility: Ensured the project runs smoothly on Quest 3 hardware by managing CPU and GPU usage.

1. User-Friendly Interactions

   • Leveraged XR Interaction Toolkit for natural hand-based object grabbing, throwing, and wearing.
   • Focused on intuitive experiences to help users feel grounded in the virtual space.

2. Comfort & Accessibility

   • Offered teleportation to minimize motion sickness.
   • Incorporated adjustable settings to allow users to tailor the experience to their comfort level.

This section captures real-time performance data collected during gameplay, focusing on CPU, GPU, and frame rate stability. These insights help identify effective optimizations and potential areas of improvement.

Observations

• CPU Usage: Frequently hovers between moderate ranges, indicating balanced processing overhead. Occasional spikes may occur during peak interactions or transitions.
• GPU Usage: Remains within comfortable thresholds, suggesting the project is well-optimized for VR rendering and visual effects.

• Optimized VR Experience: The stable frame rates and balanced CPU/GPU usage indicate strong optimization.
• Immersive & Interactive: Integration of XR interactions, object sockets, and post-processing contributes to a polished user experience.
• Future Possibilities: Further improvements could focus on advanced visual effects, more complex AI-driven interactions, and refined CPU load distribution.

This VR Room project demonstrates a successful blend of performance optimization, interactive design, and immersive visuals—all tailored for the Meta Quest 3. By combining user-friendly interactions with efficient rendering, this experience is both captivating and comfortable, establishing a solid foundation for future VR endeavors.
