Overview

Experimental study demonstrates improved asynchronous brain-computer interface accuracy and robotic arm control efficiency via phase-sliding oscillations, suggesting more reliable neuroprosthetics.

Key Points

To develop and validate an asynchronous steady-state visual evoked potential classification framework that utilizes phase-sliding oscillations to overcome EEG phase-shift degradation.
Extracted phase-decoupled features by reconstructing EEG signals into sliding-window sequences with varying initial phases and applying wavelet synchrosqueezing transforms.
Modeled signal temporal dynamics using a probabilistic framework to distinguish control from non-control states.
Evaluated classification across varying time delays in offline human experiments (N=22) and verified real-time performance using an online robotic-arm control task.
Achieved a mean control/non-control classification accuracy of 94.2% using a 2-s data length in offline testing (n=22), outperforming state-of-the-art baseline methods.
Maintained superior accuracy across diverse time delays in nine-class offline classification.
Reduced the command cost per successful trial from 4.30 to 1.14 during online robotic-arm experiments while enabling more stable command triggering.
