I'm super curious how they will implement it, if it's a general api in steam vr that headsets like the Bigscreen Beyond could use or if it's more tailored towards the Frame. I hope it's the first as to me it sounds like all you need is eye input and the two streams, the rest could be done by steam-vr.
