Title: The Eyeballing Game
Post by: watsisname on December 13, 2009, 02:49:29 am
How much do you suck at eyeballing a measurement? =P (http://woodgears.ca/eyeball/)

Basically a few tests to see how much you suck.  At the end you can see how much you suck compared to everyone else.  I sucked slightly less than average.

It seems I totally suck at determining convergence. D:

Hope someone appreciates the "Seinfeld" reference of my name choice.

Neat, though my infant son decided to smack the keyboard while playing. That means I am not posting this :)

No so good with the three side/point ones.

That's actually a quite good find! Rest assured we are going to spend some minutes playing that on working place!

Bah, only 2.66. I even got 0.0 for convergence (once), right angle (0.1 once) and circle centers seem easy also (~ 1.13 average). Triangle center was apparently the hardest one. For some reason, bisection didn't work that well either.

Most likely I never need to do bisecting and triangle centering at work.

On a completely unrelated note, except for the shared visual element, do you know how much of your field of vision is in color?

I got 8.07 on my first go. :blah:

3.45.  I got worse as it progressed.  Probably because of failure to care.

My score would have been under two if my mouse pointer didn't have an irritating tendency to hurl itself across my screen and cause me to get the occasional 87 or 89.

Inaccurate (but well working) answer: All of it

Accurate answer depends on the definition of "your field of vision" and "in color"

Got a 5.05.  Trying again to be better (as always).

I got a 3.40 :D

I actually hit a flat 0.0 on circle center and didn't go above 1.5 on bisecting angles.

High Scores as of now:
3.40  Scotty
4.79  Scotty
5.05  Scotty
6.40  Scotty

I got a 2.95 on my first try!

Also, a 0.0 on the first bisecting-angle. Terrible at equidistant triangle thing... 4.9, 3.1, 14.7

5.49

Your inaccuracy by category:
         
Parallelogram   6.4   19.8   11.2
Midpoint   7.3   2.2   4.2
Bisect angle   8.2   4.7   2.9
Triangle center   3.8   3.5   4.5
Circle center   1.0   4.0   1.4
Right angle   1.0   5.2   0.5
Convergence   7.2   4.0   12.2

Average error:   5.49   (lower is better)

On a completely unrelated note, except for the shared visual element, do you know how much of your field of vision is in color?

Is it not all or at least nearly all of it?  I'm pretty sure I can accurately determine the color of something close to the edge field of vision. <_<
Though of course the resolving power definitely goes down farther from the center.

3.10

The second angle bisect and the third triangle center hurt my score.

19 thanks to one of the triangles messing up badly (273.3, thing accidently hit next key, and though i suessed there.

Very, very little of your visual field is actually received in color. Most of it is actually just filled in by your brain. Like most of your perception, in fact - it's built off sketchy information by some very extensive neural algorithms.

See above. Your ability to perceive color in peripheral vision is for the most part an illusion.

Weeeird, that's very interesting.  It sounds like it might be a similar concept to how our brains "fill in" the eye's blindspots.; even with one eye open it's difficult to notice how large of an area (~10° 5°) is actually blank.

Yeah, it's really odd. And how you don't notice that your eyes are in fact bouncing around crazily most of the time (saccades and whatnot.) Looking at someone's eye motions while they read a book with an eyetracker on is like watching epileptic spaghetti falling out of a jet plane.

Of course the brain processes the motion out so we think our vision is stable.

If you ever find yourself having an eye floater, reading a book in relatively bright light can be maddening. Little frakkin speck moving back and forth, back and forth, back and

Field of view usually relates to the angle that you see, in this case ~ 210 degrees. Not the actual image on the retina... Hence my comment on what you actually meant with it.

Yes, the image on the retina is often of poor quality, with the exception of the small, sharp vision region. However, I still see colors at the limiting angles whether or not the retina has cells sensitive to them.

You 'see' them, sure, but they're not exactly accurate. Have somebody hold up colored items in your peripheral vision while you fixate (you must fixate, don't cheat!) on something straight ahead. You won't do too well.
