I really hope that Apple is working on this. It seems like they have at least some of the framework through the Vision; if they fire that team/abandom this software its gonna be a huge mistake.

Apple really plays the long game. More than 10 years ago, on a now defunct website for AAPL investors, there was an Apple employee who inadvertently blurted out about how his work at Apple was related to researching saccades & micro-saccades, the small rapid eye movements of the eye, as it never stays completely still, even during “fixation".

Apparently eye tracking must distinguish meaningful gaze from the natural jitters. I was thinking at that time, as an AAPL investor, that Apple seems to be wasting money on worthless R&D endeavors.

It only became apparent to me, much later with the launch of the Apple Vision Pro, how his seminal research on saccades contributed to the design and realization of the AVP.
