Is this the company Pimax is partnering with?
They mentioned they have multiple eye tracking partners. I do believe Tobi is one of them, but the eye tracker the backers will receive is not a Tobii eye tracker. The company who makes that one is 7invensun.
that’s kind of speculation
we know what the prototype shown at CES 2019 was, if that will be the item shipped to backes is to be seen
