Passive BCI beyond the lab: current trends and future directions.

Area of Science:

• Neuroscience
• Computer Science
• Human-Computer Interaction

Background:

• Significant advancements in passive brain-computer interface (BCI) algorithms and biosignal acquisition have enabled real-time biosignal analysis.
• Passive BCIs aim to quantify user mental and emotional states, with applications tested primarily in laboratory settings.
• Laboratory studies often fail to account for real-world complexities like artifacts and confounding mental states, limiting passive BCI usability.

Purpose of the Study:

• To review recent trends in advanced passive BCI technologies applied in real-world settings.
• To focus on real-time mental state evaluations in operational environments.
• To identify current progress and future challenges for integrating passive BCIs into daily life.

Main Methods:

• Review of recent literature on passive brain-computer interface (BCI) applications.
• Analysis of trends in real-world and simulated realistic settings.
• Focus on real-time mental state evaluation and related applications.

Main Results:

• Passive BCI technologies are increasingly being tested in realistic settings beyond laboratories.
• Applications include operational environments, team resource evaluation, training assessment, gaming, and neuromarketing.
• Real-world deployment faces challenges related to artifacts and the complexity of mental states.

Conclusions:

• Passive BCIs show promise for real-time mental state evaluation in diverse operational contexts.
