Re: difficulty in reading online

Don't forget that a piece of paper is not "luminized" (is that what causes
the screen to have brightness--I'm not sure what you would call it, but I'm
sure I'll be corrected if I'm wrong?) so eyestrain is not as prevelent,
which I believe allows readers/viewers to study the information easier.
When I read my screen I find myself "skimming" instead of "reading."

Bob Morrisette asked, regarding on-line vs. paper in the index:

>Again, why should they be different, except that one is on paper
>and one on the screen?

I think Lori Lathrop had the answer, it's the ability to get a "big picture"
from the printed index. But that still begs the question Bob asked: "Why?"

For the same reason why it's easier to spot a typo on a paper page than it
to spot the same typo on a screen - even when vieing WYSIWYG.

Unfortunately, here's where I'm going to fall short: I don't understand why
it's easier to spot a typo on paper. Perhaps it's screen size, or
but I have a strange feeling neither of these is it. There's something more
fundimental that we've overlooked -- that we've ALL overlooked -- that
this to happen. We've got to figure out what it is, because it's important,
whatever it is.

Two theories that I've just made up (Caution: these are both "pre-coffee"
theories early in the morning)

1) It's cultural. Even the youngest among us on this list grew up learning
paper, and we're more accustomed to absorbing information presented that
If so, then as years pass we'll find on-screen will become dominant.

2) It's in the brain. A piece of paper does not move. A screen image
and while it's -fast-, the brain -can- perceive the flicker. Perhaps the
processes the information in a different way, because the brain perceives
motion? If so, then on-screen will have a serious handicap for a long, long

Both of these theories may well be wrong. But I'd be interested in opinions
this, as well as -why- those typos are so hard to spot on-screen.
