Technical Specification Sheet: Multimodal Egocentric Data Rig

Product Code: Global-Ego-Tactile (GET) v2.6

Focus: Action-Tokenized Data for Humanoid & AR Training

1. Visual Capture System (The "Eyes")

We use a lightweight, head-mounted stereoscopic rig designed for long-shift commercial use without operator fatigue.

• * Resolution: 4K (3840 x 2160) per eye @ 60 FPS.
• * Field of View (FoV): 128° Diagonal (Fisheye calibrated via OpenCV model) to capture the human "periphery" and hand-object interactions simultaneously.
• * Optics: Low-distortion glass lenses with anti-fog coating for high-humidity healthcare or warehouse environments.
• * SLAM Integration: Built-in 6-DoF tracking to provide precise head-pose data ($x, y, z$ and roll, pitch, yaw) at 100Hz.
• 
  
• 2. Tactile Sensing Gloves (The "Feel")
• 
  
• Our gloves move beyond simple motion capture by measuring the literal physics of the interaction.
• 
  
• * Sensor Density: 65 capacitive pressure sensing elements per hand, covering all distal phalanges (fingertips) and key palm contact points.
• * Force Range: 0.04 N (minimum sensitivity) to 70 N (maximum force), allowing for the capture of both delicate surgical needle threading and heavy industrial lifting.
• * Sample Rate: 120Hz, ensuring every visual frame is paired with at least two tactile data points.
• * Material: 2.6mm thin, stretchable silicone-elastomer fabric that preserves human dexterity and "feel" during complex tasks.
• 
  
• 3. Synchronization & Metadata (The "Logic")
• 
  
• The true value of our data lies in the temporal alignment of disparate streams.
• 
  
• * Temporal Sync: Global hardware clock synchronization with <1ms jitter between video frames and pressure sensor logs.
• * Action Tokenization: Each clip is pre-segmented with "Task-Start" and "Task-Success" markers based on force-threshold triggers (e.g., the moment a grip is secured).
• * Calibration: Per-session "intrinsics.json" provided for every operator, including hand-geometry mapping and camera-to-hand extrinsic transforms.
• 
  
• 4. Data Privacy & Compliance
• 
  
• * On-Device Anonymization: Automated blurring of faces and PII (Personally Identifiable Information) in commercial settings.
• * Compliance: Fully GDPR and CCPA compliant, with sovereign data storage options for sensitive industrial or healthcare datasets.
