Brain-Computer Interface Technique to Assist Neurorehabilitation

Study in a Sentence: Researchers developed a non-invasive, brain-actuated robotic arm system, incorporating a hybrid electroencephalography-based brain-computer interface (BCI) technique and shared controller to assist people going through neurological rehabilitation.

Healthy for Humans: Brain-computer interface is a computer-based system that uses brain signals and translates them into commands that are relayed to an output device, such as a robotic arm, to carry out a desired action. This technology is often used to assist people with disabilities in performing activities of daily living. 

Redefining Research: To optimize the control and functionality of the robotic arm system, researchers built a shared controller that integrates human intention with machine autonomy and intelligence, allowing the robot to continuously learn to improve performance and capability. In this study, the shared control framework performed better than the sole BCI control, suggesting that this technique may be a favorable approach for brain-actuated systems.
