Area of Science:

  • Optics and Vision Science
  • Biomedical Engineering
  • Computer Vision

Background:

  • Eye-tracking is vital for virtual reality, neuroscience, and psychology.
  • Current reflection-based eye-tracking methods are limited by sparse 3D corneal data.
  • Achieving accurate, robust, and fast eye-tracking remains a significant challenge.

Purpose of the Study:

  • To develop a novel eye-tracking method for accurate and fast gaze direction evaluation.
  • To overcome the limitations of sparse data in existing reflection-based techniques.
  • To leverage single-shot phase-measuring deflectometry for dense 3D eye surface acquisition.

Main Methods:

  • Exploited single-shot phase-measuring deflectometry for gaze tracking.
  • Acquired dense 3D surface information of both cornea and sclera in a single frame.
  • Acquired over 3000x more surface reflection points compared to conventional methods.

Main Results:

  • Demonstrated feasibility with experimental gaze errors below 0.13° on a model eye.
  • Achieved in vivo accuracy values between 0.46° and 0.97° on human eyes.
  • Significantly increased the density of 3D surface reflection points.

Conclusions:

  • The proposed method offers a significant advancement in eye-tracking accuracy and speed.
  • Dense 3D surface data acquisition enhances the robustness of reflection-based eye-tracking.
  • This technique holds promise for improving virtual reality, neuroscience, and psychology applications.
