Actually the perceivable distortion is relative to the delta from the scene geometry starting point the headset tries to correct for so really the TV analogy does still apply as the starting point is merely uncorrected.
Flat devices obviously don’t correct for distance and magnification etc. but the analogy is actually very useful because it demonstrates that there is a *range of positioning possible before perceivable warping occurs. i.e. You are 5ft from the TV and it’s 50 degrees FOV - no distortion. You are 3ft - no problem. As you move closer the problem becomes more and more visible.
The “starting point” for VR headsets is what each manufacturer calculates as an optimal distance that the scene geometry is corrected for. *However that is where people are different and evaluations often subjective. Some need to move around within that range to achieve an optimal experience for them and *yes when they do so their FOV changes too.
TLDR: You can move around from the scene geometry correction starting point and yes many people can comfortably change their FOV to some degree.
This has diverged from the thread topic which is Artisan.
Agreed despite all the scientific methods you believe you can see more than there is. The RoV has the original steam Environment and later a developed better seperate program that is more in depth. There is also a VR robot head designed for testing HMD thoroughly.
Index was verified to have same FoV as og Vive which is slightly bigger then Vive Pro. Pimax caps out at 160.25 horizontal FoV.
Now a scientific method of testing the RoV FoV test if you have the space available you could create a real world version of this virtual test environment to test your hypothesis.
If you turn SteamVR Home off to get blank room you are in the middle of a set of circular rings that has lines segmenting the circle.
That second graphic with the diagonal 135° of the Index mixed with the horizontal 170° of the Pimax 8K/5K+ is wrong on so many accounts.
The Vive OG and Pro are shown as the same as well and larger than the Rift. I’ve had these headsets (Rift S and Index too), that graphic is just false on many points. Where did you get that picture from?
Has pimax been investigating this Quality Control issue that has been discovered that the Artisan Max FoV in both Black and Vision Housings vary from 125 to 130? Instead of the advertised specification of 140 Wide?
If using the original RoV environment @knob2001 did say it was more subjective. I imagine even the new Standalone tool will have some subjective margin for error. There are a couple of other methods using VD that can be used to measure observed FoV limits. Much like the one a dev used in the 2080 ti contest pimax hosted.
Essentially Optofidelity VR Robot for best results as less uncontrolled factors.
I guess no. I don’t think it’s a quality control issue. I suspect Pimax are in complete control of it and they modify as need be for a reason - maybe because of changes/variation in other parts of the headset such as screen or lenses.
I was surprised after watching the Mrtv review that my 8k+ on normal mode has almost no distortion compared to the Artisan. I thought it would be the other way around.
The Artisan is sharper - like the Index - but looking into the distance and certain scenes in Skyrim the 8k+ is the best looking i’ve ever seen the game. In other scenes the sharpness of the other headsets is missing. Each has their pros and cons.
The Artisan is less demanding than the 8k+ of course but it’s not as easy to run as the Index. With parallel projections on in the Pimax the Index is the easy winner if your looking for the highest SS and least amount of motion smoothing.
If Pimax has made changes to the headset that drastically changes Specifications of the headset without releasing these changes will give the company a bad reputation as being unreliable in product specifications.
Why I would prefer to give pimax the benefit of the doubt that it is a quality control issue from switching line over from making 1 headset model to another.
Plus Kevin said to contact support if the FoV is low.
Well, as much as I like Pimax I don’t think it’s a quality control issue. I think they have been fiddling with with specs. I think they released that the headset in it’s original form was going to take too many sales away from the 8K+ and needed to dampen it down.
OK, I’ll put a ticket in to Pimax saying my FOV is not 140 degrees and lets see what they come back with - I can tell you now I’ll just get a load of waffle about perception, actual, theoretical, real, face shape, foam … At best, they will say send the headset back knowing I wont as that would mean being without a headset for potentially 3 months.
Just want to add, I’m overall very happy with my Artisan given the price point - it’s just I find it interesting what has gone on here and feel a bit of responsibility to other potential customers to let them know that they are not going to get 140 FOV.
In my opinion, Pimax begins to understand that the 8K + is a HMD that has no sense of existing, just look at the current Home Page that drives Artisan and 8KX. So I hope that Artisan will be less and less penalized, as the Blue Vision version seems to make understand
Kind of. It was supposed to have better performance thanks to upscaling but as that turned out not the case and 8kX becomes real product (not just KS limited reward) then other than price 8k+ really has no place (once 8kX is available which is not yet). Just Artisan → 5k+ → 8kX would be natural progression and simple enough to understand (for customers).
But if you want to buy right now and not wait for 8kX then 8k+ makes sense (assuming it is available).
