measure ipd shows how to build vr ar glasses.

I went to my optometrist two of them and asked them to measure my ipd value they both said its 73.

 

I decided to look and see a video and it said I could use the phone app and I did and it had me hold a credit card on my forhead and on my eyebrows and take a picture and it would measure my ipd and it showed 72.5 for 1 and 73 for the other.

 

So I watched another youtube video that showed I could measure my ipd using a millimeter ruler and a cardboard and I poke two holes to measure the ipd and then look out the two holes in the cardboard to see if I can see near and far, and I could not see neither near nor far.

So, I lower my ipd until I bet around 69 to 70 millimeters and I can see both near and far!, SO maybe the measurements the doctors use don't actually measure my ipd so accurately.

 

Then it occurred to me that if this is how to measure ipd then why does oculus and apple and other vr ar headset glasses makers do it this way? Poke two holes in a see through oled, show a picture behind the see through oled, and this way measure the actual ipd of the person wearing the headset and then mold the image so the person sees the best possible image?

 

Then I thought, why not come here and tell oculus this is the way to make vr headsets since they cancelled quest 4 and make their new glasses this way? The see through oled that can hide the back display but show two tiny pin holes can also show more than two tiny pin holes it can augment the image in the rear display.

    With eye tracking, there is the math of tracking two tiny pin dot holes and psychoanalyzing them using psychology for things like marketing.

     

    All fov is paired down to two tiny pin dot holes the mind sees. This is termed the ipd but its what the person is psychologically considering as well.

     

    Without those two tiny pin sized holes the person can't see anything, all fov is irrelevant except those two tiny holes psychologically.

     

    And since science rejects what is not reproducible, if the study group disagrees on what the ipd sees and is psychologically relevant then the science is not reproducible so is useless for things like marketing.

     

    Meaning if the scientists employ streetwise "Jamal" to watch the Indian named "crow may fly", and psychoanalyze him using the eye tracking this assumes ipd is correct.
