Camera setting for field of view

[Frogger007]

What is the best parameter setting for the camera field of view to simulate the real human field of view ?

I believe for FPS cameras the most common setting is 60-75, but the human eye gives more fov than that. I think it’s around 95.
I remember working on a half-life mod and the camera setting (60?) was very narrow compared to real life fov.

What do you mean by “simulating the real human field of view” ?
Play with your hands around your head : with both eyes open I’m able to see my hands at almost 180° one from the other. One eye open it’s something like 100-130° (for myself).

Do you want the screen space to replicate the FOV of an/both eye or do you want the screen space to match the real-world field of view of the user ?

I may not be so clear, … Using techniques from optical illusion (See the french meaning for “trompe l’œil” which is not the same as “illusion d’optique”) you could want to have a different FOV according to the size of the screen and the distance of the player.
Example : with a living room 125 cm TV screen, playing at 3m from the screen, FOV would be around 60 (+/-25° ->indicative). Playing with an Iphone 12 cm screen at 50cm from it, FOV should be around 10-15°.

Here I have the good words to say it :
Do you want the screen to match an entire human eye FOV, or do you want the screen to match the actual FOV it occupies in the real-life player’s view ? (Usually we try to get close to the second solution but again it depend on many parameters)

It’s for a fps shooter project.

Wikipedia - Field of view in video games :

Console games are usually played on a TV at a large distance from the viewer, while PC games are usually played on computer monitors close to the viewer. Therefore, a narrow FOV of around 60 degrees is used for console games as the screen subtends a small part of the viewer’s visual field, and a larger FOV of 90 to 100 degrees is usually set for PC games as the screen occupies a larger amount of the viewer’s vision.[…]in many cases the narrow FOV of the console release is retained in the PC version. This results in an uncomfortable sensation likened to viewing the scene through binoculars, and may lead to disorientation, dizziness, or nausea.

But you can’t rely on that logic for a small screen at close distance (mobile, DS, …).
Note : Larger FOV = more things to draw on the screen = performance cost
Unity camera uses vertical FOV. I don’t want to go into any more explanation (google it yourself) : 74-78° should be fine !

Try this : many games (particularly first persons) have a console you can activate pressing the ² key. Elder Scrolls games have a console so if you have Morrowind, Oblivion, Skyrim, Fallout 3 or NV, lauch it. When in the game, press the ² key to activate the console, type in : fov and try as much as you want inside a complete game. (Not sure if vertical or horizontal fov, might not be made the same way Unity camera does)
