Question to anyone that knows - I know that actively "imagining" movements/activities is neurologically _very_ similar in many ways, which is why it works here for BCI. Do these "imagined" thoughts develop muscle memory?

Anyway, assuming they do, I'm not sure if it'd be a real advantage over physically swyping with your finger (for those that can obviously) - it seems like they'd be roughly equivalent?

Actually that'll be my second question - how is this system affected by things like tremors?

I'd suspect they originate from your brain in which case your "mental movements" should have the exact same quirks and limitations as physical movements.

The end game of course is not needing to use the movement system to interpret information.
