Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Human-Computer Interaction

Background:

  • Saccadic eye movements are crucial for visual perception and information processing.
  • Accurate measurement of eye movements is essential in various fields, including clinical diagnostics and user experience research.
  • Existing eye-tracking technologies may lack portability or user-friendly interfaces.

Purpose of the Study:

  • To present a novel, portable device for recording saccadic eye movements.
  • To detail the design, functionality, and accuracy of the developed Eye Tracker.
  • To ensure the device meets ISO standards for design and safety.

Main Methods:

  • Utilized infrared (IR) technology integrated into adjustable goggles.
  • Implemented a dual targeting system: a head-mounted display (HUD) or a wall-mounted light bank.
  • Developed a Windows-based user interface for data visualization (trace maps, plotted points) and management.
  • Incorporated internal memory for data logging and remote PC connectivity for portability.
  • Ensured accuracy through precise IR unit construction, crosstalk control, ambient light filtering, and a reset feature.

Main Results:

  • The Eye Tracker successfully records saccadic eye movements with high accuracy.
  • The device demonstrates portability due to remote PC connectivity and internal data storage.
  • The user interface provides flexible data representation (trace map, plotted points) and saving/printing options.
  • Design adheres to ISO standards, with safety considerations integrated throughout.
  • Features like automatic warm-up and modular IR units enhance reliability and maintainability.

Conclusions:

  • The developed Eye Tracker is a portable, accurate, and user-friendly device for recording saccadic eye movements.
  • Its design, incorporating advanced IR technology and robust data management, makes it suitable for diverse research and clinical applications.
  • The device's adherence to ISO standards and built-in safety features ensure reliable and safe operation.
