From cue-based to self-paced movement detection: Influence of the cue on training data

Research output: Chapter in Book/Report/Conference proceedingConference paperpeer-review

Abstract

The utilization of a visual cue plays a
significant role in enhancing the operational efficiency
of brain-computer interface (BCI) systems for
individuals with Locked-In Syndrome (LIS). This
significance arises from the absence of a reliable
method to discern the actual initiation of attempted
movements in these patients. First, the decoders for
identifying or classifying self-initiated movements need
to be trained on cue-based paradigms. However, these
cues can elicit neural activity (e.g., visual/auditory
evoked potentials, cognitive processing, etc.) that
obscures the neural dynamics of movement, thus
negatively influencing the performance of the decoder.
Therefore, we implemented four novel visual cues with
the intention to reduce these effects to a minimum. Our
research findings indicate that the effectiveness of
classification performance in self-paced EEG recordings
when the decoder is trained on cue-based data for
movement tasks, is significantly impacted by the design
of the cue.
