Naive question from someone not in the field but is there any solution out there that does not use IR + dark pupil segmentation?

Seems like all the solutions out there are some flavour or variation of this.

Not sure, but it would be cool to do something that didn’t require cameras, like EMG to detect eye motion from muscle activation. It would be hard to get the necessary accuracy though.
