Not sure if Pimax or their eye-tracking/wireless module development partners are aware, but DisplayLink is developing foveated compression which takes advantage of eye-tracking data to understand where to compress the frame the most and where to leave it sharp. In doing so, the company claims some pretty huge gains in compression efficiency.
“Beyond just maintaining consistent imagery under situations of reduced bandwidth, there’s also the need to be more efficient with compression so that larger frames for future headsets with higher resolution can fit in the same available bandwidth.”
