LC Technologies binocular Eyegaze System
Features:
• Calibration: Calibration is fully automated, fast, easy and can be saved for later sessions.
• Accuracy: The tracking is highly accurate and tolerant to many variations (e.g. pupil drift) typical average bias error .45 degrees.
• Remote Video Tracking: The System is unobtrusive and undistracting.
• Temporal Resolution: 8,3ms at 120Hz sampling-rate (binocular)
