Area of Science:

  • Human-Computer Interaction
  • Neuroscience
  • Wearable Technology

Background:

  • Emerging low-cost, lightweight EEG headsets increase the feasibility of consumer-oriented brain-computer interfaces (BCI).
  • Portable smartphones combined with EEG headbands offer new human-computer interaction methods.
  • Augmented reality (AR) applications can benefit from user state information provided by BCIs.

Purpose of the Study:

  • To implement and evaluate a mobile BCI system integrating user attentional state awareness into a smartphone AR application for written language translation.
  • To classify user attention (internally vs. externally directed) using a low-cost EEG device and adapt AR translation behavior accordingly.

Main Methods:

  • Utilized the Muse 2 EEG headband with four frontal electrodes to classify user attentional state.
  • Developed a smartphone application integrating the BCI for an AR written language translator.
  • Tested the system with 12 participants to assess usability and performance.

Main Results:

  • Presented the first mobile BCI system for AR applications using a smartphone and a low-cost EEG device.
  • Participant study did not fully confirm improved usability, but demonstrated promising classification accuracy and ease of setup.
  • The system adapts AR translation app behavior based on classified user attention.

Conclusions:

  • The developed mobile BCI system shows potential for consumer-oriented applications, particularly in AR.
  • Classification accuracy and ease of setup are key strengths for future development.
  • Further research is needed to explore diverse use cases and optimize usability.
