A high-performance brain-computer interface for finger decoding and quadcopter game control in an individual with...

Area of Science:

• Neuroscience
• Rehabilitation Engineering
• Human-Computer Interaction

Background:

• Individuals with paralysis often experience unmet needs for social engagement and leisure activities.
• Social media and video games are common coping mechanisms for the general population to fulfill these needs.
• There is a need for advanced assistive technologies to improve quality of life for people with paralysis.

Purpose of the Study:

• To develop and evaluate a high-performance, finger-based brain-computer interface (BCI) system.
• To enable continuous control of multiple degrees of freedom for individuals with paralysis.
• To assess the system's potential in restoring function and addressing unmet social and recreational needs.

Main Methods:

• Development of a finger-based BCI system with four degrees of freedom for continuous control.
• Testing the system with a participant with tetraplegia, focusing on target acquisition tasks.
• Utilizing the BCI to control a virtual quadcopter for navigation through obstacle courses.

Main Results:

• The BCI system achieved an average acquisition rate of 76 targets per minute.
• The system demonstrated favorable performance compared to previous studies, despite increased complexity.
• The participant successfully navigated a virtual quadcopter, expressing enablement and social connectedness.

Conclusions:

• The developed finger-based BCI system shows significant potential for restoring functional control in individuals with paralysis.
• This technology can address critical unmet needs for recreation, social connection, and independence.
• BCI advancements offer promising avenues for improving the quality of life for people with spinal cord injuries.
