This study introduces a novel brain-computer interface (BCI) combined with eye tracking for 3D applications. This integrated system enables depth navigation and selection for users, enhancing accessibility in virtual environments.

Area of Science:

  • Human-Computer Interaction
  • Neuroscience
  • Biomedical Engineering

Background:

  • The proliferation of 3D applications necessitates advanced interaction interfaces.
  • Existing eye-tracking methods are limited in depth navigation for 3D environments.
  • Hand-disabled individuals require accessible and effective control mechanisms for complex digital interactions.

Purpose of the Study:

  • To develop and validate a novel hybrid interface combining eye tracking and brain-computer interface (BCI) for 3D application navigation.
  • To enable depth directional control, selection, and 2D gaze tracking within a unified system.
  • To enhance interaction capabilities for users, particularly those with physical disabilities.

Main Methods:

  • Development of a head-mounted device integrating eye-tracking sensors and electroencephalogram (EEG) measurement capabilities.

  • Verification of BCI reliability by comparing EEG power spectrum for real versus imaginary movements.
  • Implementation of depth control via imaginary arm reaching and selection via imaginary hand grabbing.
  • Introduction of a mode selection mechanism using pupil accommodation speed to ensure independent operation of gaze and BCI.

    • Main Results:

    • Experimental validation confirmed the feasibility of the proposed hybrid eye-tracking and BCI system.
    • The system successfully demonstrated depth navigation, selection, and 2D gaze control.
    • EEG analysis verified the reliability of the BCI for movement intention detection.
    • Pupil accommodation speed effectively facilitated independent mode switching.

    Conclusions:

    • The integrated eye-tracking and BCI system offers a viable solution for enhanced 3D interaction.
    • This approach significantly improves depth navigation and selection capabilities, overcoming limitations of traditional eye tracking.
    • The developed interface holds promise for improving accessibility and user experience in 3D applications, especially for individuals with motor impairments.
