Current trends in hardware and software for brain-computer interfaces (BCIs)

Area of Science:

• Neuroscience and Biomedical Engineering
• Focus on Brain-Computer Interface (BCI) technology

Background:

• Brain-computer interfaces (BCIs) establish non-muscular communication channels.
• BCI systems comprise hardware for brain signal acquisition and software for signal translation and feedback.
• Existing BCI applications span basic research, clinical/translational research, consumer products, and emerging areas.

Purpose of the Study:

• To summarize the technical aspects and requirements for different categories of BCI applications.
• To analyze the evolving landscape of BCI technology from research to commercialization.

Main Methods:

• Categorization of BCI applications into four distinct groups: basic research, clinical/translational research, consumer products, and emerging applications.
• Analysis of the differing hardware and software requirements for each BCI application category.
• Review of technical considerations for BCI system development and deployment.

Main Results:

• BCI applications exhibit diverse technical requirements based on their category.
• Basic research demands broad system flexibility, while other categories often require specialized, limited capabilities.
• BCI technology is transitioning from isolated studies to systematic research and commercial development.

Conclusions:

• The advancement of BCI technology necessitates multidisciplinary efforts.
• Key areas for development include integrated and robust hardware/software, standardized interfaces, and streamlined certification/dissemination processes.
• Successful commercialization requires addressing regulatory and reimbursement procedures.
