🚀 What's New in Aria Gen2

Aria Gen2 introduces significant hardware and software improvements with full API support in this 2.0.0 release.

Hardware & Sensors

  • 12MP RGB camera, 4 CV cameras (wider FOV, HDR, front-facing stereo), 2 eye tracking cameras
  • New sensors: Proximity, contact microphone, PPG health, ambient light, GNSS
  • 6-8 hour battery life, foldable form factor, direct interactivity with open-air speakers

On-Device Machine Perception

On-device algorithms powered by a custom Meta co-processor:

  • Eye Tracking, Hand Tracking (21 keypoints), VIO/SLAM (20Hz + 800Hz high-freq trajectory)

Software & Tools

  • Unified APIs: Same Python/C++ interface for both Gen1 and Gen2 data
  • New Tools: aria_rerun_viewer (interactive 3D visualization), gen2_mp_csv_exporter, upgraded vrs_health_check
  • Enhanced Streaming: USB/wireless sensor streaming with on-device perception signals
