Hardware Specifications¶

The Moon AR platform is built on custom hardware optimized for augmented reality applications with strict resource constraints.

Core Hardware¶

Component	Specification	Implications
Processor	Qualcomm SoC	Optimized for low-power AR workloads
Memory	4GB LPDDR4	Strict memory management required
Storage	4GB eMMC	APK + assets must be ≤ 600MB
OS	Custom Android 9	Modified launcher, system apps removed

Sensor Array¶

Camera System¶

graph TD
    A[Camera Manager] --> B[RGB Camera]
    A --> C[Eye Tracking Cameras]
    B -.-> D[Mutual Exclusion]
    C -.-> D
    D --> E[Single Active Pipeline]

Camera Components:

RGB Camera: Front-facing, computer vision tasks
Eye Tracking: Dual near-infrared cameras
Exclusivity Rule: Only one camera system active at a time

Motion Sensors¶

6DoF IMU: Head tracking and spatial orientation
Neural Wristband: Hand gesture recognition
Capacitive Slider: Direct touch input

Performance Constraints¶

Memory Management¶

// Example: Proper resource cleanup
override fun onPause() {
    super.onPause()
    camera?.release()    // Critical for camera switching
    System.gc()          // Encourage garbage collection
}

Storage Optimization¶

Use Split APK delivery for ARM64 only
Compress textures to ETC2 format
Stream large assets rather than bundling

Hardware Limitations

The 4GB storage includes system files. Your application bundle should not exceed 600MB total.

Developer Testing Hardware¶

Physical Device Required¶

The Moon AR device is essential for:

Eye tracking integration testing
Camera switching validation
Gesture input verification
Performance profiling

Emulator Sufficient¶

Android 9 emulator works for:

Business logic testing
UI layout verification
Plugin development
