Wearable Eye Tracker
Equipment Introduction
Tobii Pro Glasses 3 delivers advanced wearable eye tracking within real-world settings, capturing natural visual behavior during participant movement with minimal interference from its lightweight design. Featuring a high 100 Hz sampling rate for precise dynamic gaze measurement, easy one-point calibration, and integrated slippage compensation technology, it ensures reliable data accuracy across diverse lighting conditions even during extended use or head motion. Precise gaze points are overlaid onto wide-angle HD scene video, providing authentic insights into attention patterns. With intuitive operation including Wi-Fi live viewing and comprehensive analysis in Tobii Pro Lab software, these glasses empower transformative research in consumer behavior (packaging/shelf visibility), human-computer interaction (interface usability), ergonomic safety (hazard identification), and other applications requiring objective measurement of visual attention dynamics.
