Relationship between display and field of view

The section "Relationship between display and field of view" tried an interesting idea, namely to derive an immersive index. However, this is not established knowledge and Wikipedia rules do not allow for what is called original research (WP:NOR). I copied the previous version below, in case somebody has a reliable source for it. I kept the first part of the section and edited it to be factually correct.

Old version:

In practice, considering that the curved display cannot be made into a spherical shape, it is approximated by a cylinder instead.

Relationship between display and field of view: We need to consider our field of view (FOV) in addition to quality image. Our eyes have a horizontal FOV of about 120 degrees per side and a vertical FOV of some 135 degrees. Stereopsis vision is limited to 120 degrees where the right and the left visions overlap. Generally speaking, we have a FOV of 200 degrees x 135 degrees with two eyes. However, most of it is peripheral vision, which varies from one person to another. So we conservatively take the average, i.e. 160 degrees. Therefore, if we keep our eyes stationary, a regular participant will have at least a stereopsis of 160 degrees x 135 degrees or 1/6 of the 360-degree FOV. We can quantify the abstract concept of immersion with the immersive index by getting the ratio of display viewing area and 1/6 of the 360-degree FOV.

In theory,

${\frac {\mbox{Display Area}}{{\frac {1}{6}}\times 4\pi {\mathsf {R}}^{2}}}={\mbox{Immersive Index }}$

In practice, considering that the curved display cannot be made into a spherical shape, it is approximated by a cylinder instead.

${\frac {\mbox{Display Area}}{{\frac {1}{6}}\times {\bigl (}2\pi {\mathsf {R}}{\bigr )}^{2}}}={\mbox{Immersive Index }}$

Maybe-salvageable draft

It looks like in November of 2021 Joseita Tesolin forked this article with the intent to merge back an improved version, but did the merge-back incorrectly, so nothing was ever actually added to mainspace. See Special:PageHistory/User:Joseita Tesolin/Virtual reality. I haven't looked too closely at what they added, but perhaps someone wants to take a look and see if any of it can be salvaged for use in this article? -- Tamzin^{[cetacean needed]} (she|they|xe) 07:36, 12 January 2023 (UTC)
