Welcome to Aria Research Kit

Aria Research Kit (ARK) is a comprehensive development platform for the Aria Gen 2 glasses, designed to empower researchers and developers to build cutting-edge applications in egocentric AI, contextual AI, robotics, spatial computing, and human-computer interaction. ARK provides everything you need to capture, process, and analyze data from Aria's advanced sensor suite.

What is Aria Gen 2?​

Aria Gen 2 is a state-of-the-art research device featuring an advanced sensor suite that includes:

  • Four computer vision (CV) cameras with wide field of view and HDR imaging
  • RGB point-of-view (POV) camera for high-resolution egocentric vision
  • On-device VIO for real-time 3D tracking and mapping
  • On-device Eye tracking system for precise gaze estimation and attention modeling
  • On-device 21-keypoint hand tracking for articulated hand pose estimation
  • Spatial and contact microphones for high-fidelity audio capture
  • IMU, barometer, magnetometer, and GNSS for accurate localization and motion tracking
  • Ambient Light Sensor (ALS) with UV channel for indoor/outdoor context awareness
  • PPG sensor for heart rate monitoring

See Hardware Specifications for more details.

What You Can Do with ARK​

🎮 Control Your Device​

Use the Client SDK to programmatically control Aria Gen 2 devices:

  • Start and stop recordings
  • Stream sensor data in real-time
  • Access on-device machine perception outputs (VIO, hand tracking, eye gaze)
  • Configure recording profiles for different research applications
  • Automate device workflows with Python scripts or CLI tools

📱 Mobile Companion App​

Pair your device with the Companion App to:

  • Configure and manage your Aria Gen 2 glasses
  • Start recordings with a simple interface
  • Monitor device status and battery life
  • Manage recordings from your phone

🔍 On-Device Machine Perception​

Run real-time algorithms directly on Aria Gen 2:

  • Visual Inertial Odometry (VIO) at 10Hz (and 800Hz high-frequency output)
  • Eye gaze tracking at up to 90Hz with pupil diameter and vergence depth
  • Hand tracking at 30Hz with 21 joint landmarks per hand

🧠 Machine Perception Services (MPS)​

Leverage cloud-based processing to generate rich outputs from your recordings:

  • 3D trajectory and semi-dense point cloud
  • Hand tracking

All optimized for all-day wearability with energy-efficient hardware acceleration.

🛠️ Data Analysis & Visualization​

Use the comprehensive toolset to:

  • Validate recording quality with VRS Health Check
  • Visualize sensor data streams
  • Export data in standard formats
  • Build custom analysis pipelines

Getting Started​

Choose your path based on your role and objectives:
