Area of Science:

  • Computer Vision
  • Human-Computer Interaction
  • Biomedical Engineering

Background:

  • Conventional eye-tracking algorithms are limited to single-user applications.
  • Existing multi-user systems suffer from low detection accuracy and inability to individually identify users.

Purpose of the Study:

  • To develop a robust multi-user eye-tracking algorithm capable of accurate individual identification.
  • To enhance the detection accuracy and performance of multi-user eye-tracking systems.

Main Methods:

  • Utilizes a classifier for face detection in RGB and depth images.
  • Employs Histogram of Oriented Gradients (HOG) features for user identification.
  • Matches detected users against a pre-defined face database.
  • Extracts eye positions using anatomical proportion estimations.

Main Results:

  • The proposed algorithm significantly improves multi-user detection accuracy.
  • Achieved an average F₁ score improvement of up to 0.490 compared to benchmark algorithms.
  • Demonstrates effective individual identification within a multi-user environment.

Conclusions:

  • The novel algorithm overcomes limitations of traditional single-user eye trackers.
  • Provides a more accurate and reliable solution for multi-user eye-tracking applications.
  • Offers potential for enhanced human-computer interaction and user monitoring systems.
