The 'Brussels 4': essential requirements for implantable brain-computer interface user autonomy

Area of Science:

• Neuroscience
• Biomedical Engineering
• Rehabilitation Technology

Background:

• Implantable brain-computer interfaces (iBCIs) show significant potential for individuals with severe paralysis.
• Advancements in iBCI technology are progressing towards commercialization.
• Traditional academic research may overlook critical factors for clinical translation and patient adoption.

Purpose of the Study:

• To identify key considerations for achieving user autonomy with iBCIs.
• To bridge the gap between academic research and real-world clinical application of iBCIs.
• To inform the development of iBCIs for successful patient adoption and integration.

Main Methods:

• Analysis of discussions and workshops from the 10th International BCI Society Meeting (2023).
• Synthesis of expert perspectives on critical factors for iBCI user autonomy.
• Qualitative assessment of requirements for clinical translation.

Main Results:

• Four critical considerations for iBCI user autonomy were identified: immediate use, ease of use, continuous use, and stable system performance.
• These factors are essential for enabling patients to effectively utilize iBCIs in their daily lives.
• The identified factors highlight the need for user-centered design in iBCI development.

Conclusions:

• Addressing the identified considerations is crucial for the successful clinical translation of iBCIs.
• Focusing on user autonomy can accelerate the adoption and impact of iBCI technology.
• Future iBCI development should prioritize immediate, easy, continuous, and stable system use to maximize patient benefit.
