Hey guys, after seeing Sebastian’s video where he compared the FOV of various headsets using the ROV test tool, I decided to do my own comparison between the StarVR One and the Valve Index.
My optometrist measured my IPD at 63, but StarVR’s eye tracking suggested my IPD is actually 64 and it has many times measured it at 65. So I’ll say my IPD is between 64 to 65.
For Valve Index test I put the lenses as close to my eyes as possible with ipd set to 65
Pretty much the same as Sebastian’s results. For me it was 106 and for him 108 horizontal.
Now for the StarVR One:
At 170 degrees horizontal I could still see the colors of the bars in my peripheral. Between 172 to 176 I could see reflections on my screen but not the color of the bars.
For vertical FOV, what’s interesting is for both the Valve Index and StarVR One, I started noticing the dot at the top disappearing at around the 94 degrees mark. The point at which the bottom dot disappeared from my view was 116 degrees on StarVR and 130 degrees on Index.
However, in terms of my VR experience, seeing more from below my eyes is not as important as above my eyes. I could not tell much difference between vertical FOV of both headsets until I actually did the measurement.
So in comparison:
Valve Index Max 106°/130°
Pimax 8KX 140°/124° (from Sebastian’s measurement)
StarVR One 172°/116°
StarVR has roughly 32 degrees wider horizontal FOV than the 8KX.
