A few comments I have on this analysis:
Is it actually reasonable to put your eyes at 5mm from the lens? The depth of my eyelids might even be that much, so even when not considering eyelashes leaving oil all over the lens, this seems way too close. This leads me to think that the CV1 lenses might be purposefully optimised to peak FoV at 10-15mm as it seems a much more realistic minimum distance. Shame they didn't include any way of making sure your eyes actually can get as close as possible!
This is measuring the FoV of a single lens, yes? Depending on the size of a person's nose, the left FoV in the right eye, and the right FoV in the left eye, are both limited more than their counterparts (left FoV in left eye and right FoV in right eye). Due to this, the amount that the vision from both eyes need to cross over (the 3D part) is reduced. Thus, it would make sense to not fully overlap the FoV of the lenses, meaning that measuring the FoV of a single lens doesn't actually give an accurate representation of the overall FoV one experiences when wearing the headset. It looks to me that the CV1 exploits this more than the vive, by having a smaller crossover area, meaning the FoV is larger than it will measure in this test. I think that's the reason that most people say they can't actually perceive the difference in FoV anecdotally.
Thoughts? Is there anything wrong with my thinking? This is a pretty complicated subject so I might do a full post with diagrams about it sometime. Not trying to take anything away from either headset, just want to make sure the analysis is right if people are going to base their purchase choices on it.
