This study introduces an automatic remote gaze estimation calibration that requires no user interaction. The novel method accurately estimates eye-specific angles for improved gaze tracking without active subject participation.

Area of Science:

  • Computer Vision
  • Human-Computer Interaction
  • Biomedical Engineering

Background:

  • Remote gaze estimation systems typically require user calibration for accurate point-of-gaze calculation.
  • Existing advanced systems may reduce calibration but still rely on specific user actions or single calibration points.
  • Accurate estimation of the angle between the optical and visual axes is crucial for gaze tracking precision.

Purpose of the Study:

  • To develop a novel automatic calibration procedure for remote gaze estimation that eliminates the need for active user participation.
  • To estimate the angles between the optical and visual axes for each eye without requiring subjects to fixate on specific points.
  • To enable natural viewing behavior, such as watching videos, during the calibration process.

Main Methods:

  • The proposed method involves minimizing the intersection distance of the left and right eyes' visual axes on a display surface.
  • This is achieved while subjects naturally view the display, allowing for passive data acquisition.
  • The procedure estimates subject-specific angles between optical and visual axes without explicit user commands.

Main Results:

  • Simulation results indicate that algorithm performance improves with a wider range of viewing angles.
  • For a typical setup (75 cm viewing distance, 40" display), the standard deviation of the error in angle estimation is 0.5 degrees.
  • The automatic calibration procedure demonstrates high accuracy in estimating crucial eye-gaze parameters.

Conclusions:

  • The developed automatic calibration procedure offers a significant advancement in remote gaze estimation technology.
  • It removes the burden of active participation from users, making gaze tracking more accessible and user-friendly.
  • The method provides accurate estimation of optical and visual axis angles, enhancing the reliability of gaze estimation systems.
