Area of Science:

  • Neuroscience
  • Human-Computer Interaction
  • Virtual Reality

Background:

  • Brain-computer interfaces (BCIs) offer communication and control for individuals with motor impairments.
  • Existing BCI applications lack public accessibility and widespread usability.
  • There is a growing need for user-friendly and open-source BCI solutions.

Purpose of the Study:

  • To develop and evaluate an accessible, open-source BCI application for virtual world exploration.
  • To assess the usability and performance of the BCI system in healthy participants.
  • To contribute to the advancement of open science within the BCI field.

Main Methods:

  • Developed a BCI application utilizing three open-source environments.
  • Conducted a usability test with 10 healthy subjects using electroencephalography (EEG).
  • Collected user feedback through a questionnaire assessing system usability and experience.

Main Results:

  • All participants successfully operated the BCI virtual world tour application.
  • Achieved a high accuracy rate of 96.6% with 20 blinks across two sessions.
  • Participants provided positive feedback on the system's controllability, completeness, comfort, and enjoyment.

Conclusions:

  • The developed open-source BCI system is effective for virtual world experiences.
  • The application demonstrates potential for both research and entertainment purposes.
  • This work promotes open science and enhances BCI accessibility.
