The flatness of computer screens and the human eye

A few weekends ago I was futzing around playing a game (Xplorers) online & this kid from down the street knocks on my door asking if I want to play ping-pong. I'd been online for about eight hours straight & was in a bit of a funk & not feeling super social but in the spirit of spiritedness & decided to take him up on it.

Don't know whether it was my mood & what but the shift was quite intense, bordering on surreal that day. I went from a still two dimensional world to one where I had to instantly gauge & react to a moving ball in three dimensions (made more interesting by a less than perfectly flat ping-pong table & a net that's a bit saggy in the middle). I must say I found it a quite pleasurable shift.

Wondering how focusing vision onto a 1-2 square foot flat object much of the day affects it is just the tip of the iceberg of course. It's also wonderworthy how the act of, say driving, and all the physiological aspects thereof affects the human animal.

Of course things like this will probably never get studied because they are a matter of pure curiosity with little to no profit in them.

Common sense dictates though that this, and dozens of other, "routine" activities are pretty far removed from the day to day physical, visual, auditory, olfactory life we evolved with. Not to say, in moderation it is particularly bad, it'd just be interesting to do lots of tests on people with various lifestyle habits (flexibility, coordination, mapping their brains to see the size of various regions connected to certain motor activities & even emotions & all sorts of other variables I cannot think of ATM). It would also be interesting to see how such a lifestyle affected people mentally, emotionally & philosophically.

I'd imagine the personal computer & Internet are high up there in terms of modern changes that have most affected our lives, biorhymes, perceptions, bodies & minds (along with automobiles, electric lighting, telephones & many other inventions that allow us to surpass natural limits & often focus a single sense & neglect all others [for example a telephone or a computer monitor]).

Kind of reminds me that experiment where they raised some kittens in environments where all the objects they interacted with had vertical lines & how it altered their perception for life. (sry, can't find a link to the experiment right now :blush:, someone will though :))

Anywayz, it's 2:47AM and I'm wondering how much more clearly I could articulate if I was on a 5:30AM-10PM schedule like I was back in Mexico in the summer of '99. :crazyeye:

So, feel free to discuss the subject.
 
I remember well visiting a friend during school lunch breaks to play Comanche. Walking back to school after one hour of vicious aerial combat in a (simulated) machine that can make any pilot puke was.... interesting, to say the least.

:crazyeye:


And yes, quite obviously this is a real problem if the user is too young. If the correct connections between inner ear and optical stimulus with regards to motions are not already fixed, excessive computer use may cause erroneous ones to be set. I think this is much more important than the lifestyle of an adult.

Yeah, definitely, I don't want my daughter to be a "heavy user" before... well, ever really (my definition of heavy is 4+ hours a day).
 
Ah shoot, my post got deleted.

Damn... I was really flowing there too, don't think I can recreate it.

Just wanted to say I found this article interesting (slightly off topic, maybe I should generalize the topic) though not suprising news.

Basically it stresses the importance of natural light during the day & warns that unnatural light at night (lights, computer screens, etc.) have health consequences. Funnily enough I found it replying to a pic on the funny pics thread.

I am going to make an effort to minimize my computer use after dark (it will be hard! :undecide: ). I already get a good amount of natural light everyday as I work outside most days. Which reminds me of another noteworthy issue on the subject of technology, culture shift & untended consequences.

Babies like to put things in their mouths, in a home environment with toxicity all over the floor (chemicals in carpets, plastic objects that disrupt hormones in the body & pollutants from the bottom of shoes this is not so smart but getting dirt on their hands & putting it in their mouths is actually good for their immune systems when they are outside. The opposite extreme would be a "bubble boy" type case where a child was protected completely & thus their immune system was to an average person's as Steve Urkel would be to a group of elite bodybuilders.

We simply haven't had time to adapt to the world we inhabit. Of course there's no going back, and, not being a primitivist, I wouldn't care to. However, it pays to be aware of our history & learn from it so we can maximize the fruits that modern world has to offer while minimizing it's side effects.

Some might argue a better approach would be to try to genetically engineer ourselves to adapt us to our new environment but this is an unrealistic goal & a bit hubristic honestly.
 
My sister did her Optometry doctoral thesis on the effects of video games on the eye. Hours and hours of having people play snood. I don't remember the exact results, but the pros do research this stuff.
 
Snood?

Cool this thread didn't sink into oblivion.

If your sis is willing to share her thesis I'd be curious to read it & could agree not to share/reproduce it. Let me know. :)
 
Here it is. Not sure exactly how to get the full text. It's published, so just use proper attribution in your work.
 
Thanks, I can't see anything there though. If you talk to your sis & she's got a copy I'd be curious to read it, I won't repost it.
 
@OP

I don't have a source seeing as how I read this several years ago, but, Surgeons who play video games at least 3 hours a week make 30% less mistakes than those who don't. Post 3 hours there is no significant difference.



Also: I think my circadian rhythms are messed up to a degree by light, but I think it has more to do with when and why I started staying up so late all of the time.
