Virtual reality (VR) enhances medical applications by improving 3D anatomical visualization and human-computer interaction. Integrating eye tracking and hand gesture recognition creates intuitive interfaces for medical training and procedures.

Area of Science:

  • Medical technology
  • Computer science
  • Human-computer interaction

Background:

  • Virtual reality (VR) offers novel human-computer interaction methods with significant potential in medicine.
  • VR applications can assist physicians, improve interdisciplinary communication, and serve educational/training purposes.

Purpose of the Study:

  • To introduce a VR application for enhanced visualization and analysis of 3D anatomical data (CT/MRI).
  • To develop a human-oriented interface for intuitive interaction within virtual environments.
  • To integrate advanced human-machine interface components for improved user experience.

Main Methods:

  • Utilized eye tracking parameters for a level-of-detail algorithm.
  • Integrated glove-based hand gesture recognition for natural interaction.
