- RGB Cameras: Capture color and texture; used for photogrammetry, NeRFs, and Gaussian splats.
- LiDAR: Emits laser pulses to measure depth; builds high-fidelity spatial meshes.
- IMU (Inertial Measurement Unit): Combines accelerometer + gyroscope for motion tracking and orientation.
- GPS: Provides global positioning; fused with IMU for macro-localization.
- Eye Tracking: Enables gaze-based interaction, rendering prioritization, and contextual memory.
- AI Fusion Chips: Handle real-time sensor fusion, semantic labeling, and spatial memory management (e.g., Apple R1, Qualcomm XR2).
