What degree does the human eye perceive? I heard once 170* ??? What lens would match what the human eye can perceive..

There are many variables that need to be stated. This is a good overall study:

The eye can perceive a very wide angle, but of course much of what your eye sees is not in focus. At any given time, only light falling on the center few degrees of your field of vision (your fovea, packed with color sensitive cones) is in the so called "sweet spot" of vision.

So, going with that concept, the lens that approximates your eyes' "sweet spot" can range from 80mm to over 100mm. Think about it: you may be able to "see" a wide field, but you cannot keep it all in focus at one time.

Many places will also say a 50mm lens (~32mm on APS-C) is a "normal" lens since it approximates what the eye can see. I haven't found this true in my experience, and I believe it is more attributed to the fact that a 50mm lens has almost no perspective distortion since 50mm is the diagonal of the frame size of 35mm film.

No, I understand. It is impossible to see view the entire degree your eye is seeing. I'd like to go wider on my HF S100 and widen the FOV

Some people have peripheral vision (can see movement and blurred image but not details) beyond a 200 degree field of view. I don't think any camera lens can do that. However, a wide fisheye lens can record a wider field of details than any human eye can "process". As a rough experiment, I just did a small test and while looking straight forward I can see at least some details (I can't read words at the far edges, but I can distinguish shapes and colors) in a field of view of about 140 degrees with one eye open and one closed which - I believe - is a bit wider than the angle of view with a 10mm fisheye on a full frame camera.
