Spinning Icons: Introducing a Novel SSVEP-BCI Paradigm Based on Rotation
summary
Introduces a new SSVEP paradigm using spinning icons—icons rotated around their vertical axis at 7.5, 10, or 13 Hz—and tests it with a g.Nautilus EEG headset using Oz as the active channel and filter-bank CCA offline classification. Ten usable participants yield roughly 70–75% balanced accuracy (PDF icon peaks at 75% balanced accuracy), 7.5 Hz shows presentation issues, and subjective ratings report lower visual fatigue than motion-based stimuli. Implementation works in lab conditions and invites online and icon-variation followups.
