Area of Science:

  • Neuroscience
  • Computer Science
  • Geometry

Background:

  • Visual perception involves complex patterns influenced by stimulus and individual perception.
  • Traditional Euclidean geometry struggles to measure these complex, self-similar visual patterns.
  • Fractal geometry provides tools to quantify complexity at different scales.

Purpose of the Study:

  • To explore the application of fractal geometry in analyzing eye gaze patterns.
  • To quantify the geometric and temporal complexity of visual perception.
  • To identify potential markers for neurological pathology using fractal analysis.

Main Methods:

  • Utilizing fractal dimensions, including the Higuchi fractal dimension (HFD) and Minkowski-Bouligand dimension.
  • Employing Hilbert curves for dimensionality reduction in eye gaze data.
  • Implementing fractal analysis within machine learning frameworks.

Main Results:

  • Fractal methods successfully quantify geometric complexity and matchability in eye gaze patterns.
  • Fractal dimensions effectively measure temporal and geometric complexity.
  • Demonstrated potential for machine learning applications in analyzing visual perception.

Conclusions:

  • Fractal geometry is a powerful tool for analyzing complex eye gaze patterns.
  • This approach can reveal markers associated with neurological conditions.
  • Future research can integrate fractal analysis into eye-tracking diagnostics for multiscale information acquisition.
