One time when I was a teen I woke up and my brain wasn’t doing saccadic masking for a few seconds, I would move my head left and right and things would motion blur. Eventually it turned back on though. Any idea what that was?

Saccadic masking isn't about head movement. That would be a problem with your vestibulo-ocular reflex. I'd say a likely cause would be an issue with your inner ear, perhaps temporary benign paroxysmal positional vertigo caused by a bit of debris coming loose inside.

    Haha, actually I had an episode of BPPV myself, not related to my VR work. Triggered by a day of snorkeling, of all things.

      I feel that AR/VR are a very interesting intersection of medicine, biology, mathematics and physics. Given you actually work in the industry, what is your experience in this regard? Do people have to have some knowledge in all these fields, or do you rather have strongly focused specialists in each who then collaborate? E.g. you clearly need some biology/medical knowhow to be able to diagnose various problems that arise in the human part of the system, no?

        Just off the cuff, I'd say specialists are important in some areas. But you won't get very far without generalists who can see the whole picture, and study to become specialists where necessary. In a new field, the right specialists may not exist. I wouldn't say you need a medical degree to diagnose VR-specific biological issues. A lot of this stuff hasn't been particularly well studied so you're going to be discovering new things rather than applying existing knowledge. On the other hand optics specialists are very important; optics is very deep and existing knowledge is very relevant.
