Eyeball Engineering question?

[SamIyam]

I heard a term the other day about eyeball engineering... and thought of a way I could encorporate it into my shop class.

When lining up two things by sight, you need to look at them in a row, or line. i.e. Like when you line up the pointer on a machine with a mark on its rule... anyway, the "error" that occurs when you are looking at it at an angle has a term... what is that term?

TIA,
Sam.

cockeyed !!!! ??? LOL

Is parallax what you're looking for?

Similar deal in rangefinder cameras . . . what you see through the viewfinder isn't quite what you get through the lens because of the different angle . ..

No, not parralax... it's kind of a long word... I'll know it when I read it. http://www.jalopyjournal.com/ubbthreads/images/graemlins/smile.gif

I think the proper name is "Parallax Error",


or Fucked Up.

Collimation?

We always used the term "optical illusion"

Parralax or parrolox(sp?) deflection. Only thing I remember from a year of electrocics technology class in sixties. If you do not look at a gauge or instrument straight on 90 degrees will not get the correct reading. Unless it is digital!! http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

I think that's it! I guess you guys had it right after all... just that word deflection was missing.

Another example is a gun sight...

Sam, another thing to remember about eyeball engineering is "if it doesn't look right, it usually isn't!"

More parallax than you can shake a stick at, depending on which eye is closed of course...

To eliminate the difference you are talking about, the eye doctor calls it mono vision. If you are talking about the scew (sp?) when you use two eyes.

Our field crew calls it the Miller (as in High Life) eye!
