Writing with Two Hands Simultaneously

I mentioned in a previous post that I taught myself to be ambidextrous. Occasionally I'll take notes in class with my left hand, partly to avoid the binding of my spiral bound notebook and make the most effective use of the space on the page, and partly just to get practice writing left-handed. However, this is still a lot slower, so most the time I wind up switching back to my right hand to catch up.

One day last week, I became curious as to just how much slower I am with my left hand now. I wrote out “The Sound of Silence” Simon and Garfunkel lyrics (since that's one of the few songs I have completely memorized) with each hand, timing how long it took to write each verse. Then, I calculated how many times slower I was with the left hand for each verse and the average came out to 2.5 times slower than the right hand. Better than it used to be, certainly.

But then there was the old problem of the left hand smearing what's already been written. What if I wrote from right to left? Of course, to make practical use of this I'd have to get really good at judging how many words I could fit on a line, but the idea intrigued me nevertheless. So I tried picking off each letter from the end, one by one, essentially writing each line of the verse backwards. But the spacing was off, both between letters and between words, since each letter started from left to right.

To truly write backwards I realized I would have to reverse the strokes I used to write each letter (for example, a “t” would be written by doing the cross at top first, then coming up through it). This would also take care of the spacing problem, since the letters would be written mostly from the right to left.

I wrote another verse “exactly” backwards with each hand, then thought of yet another fun experiment; writing a mirror image. This wasn't nearly as challenging as I thought it would be (in fact, it was simpler than writing backwards) since after a very short period of time my mind seemed to reverse the letters automatically. Strangely, when I tried to think about the letters I was writing, I had trouble remembering which way they went, such as a “b”. I think I got just a bit of an idea of what dyslexic people might feel like. In any case, it was fun seeing how normal my writing looked when I held it  up to a mirror.

Finally, I picked up a pen in each hand, divided the page in half, and wrote the same verse with each hand simultaneously. It took a bit of getting used to, and I had to make sure I was doing exactly the same thing with each hand down to crossing my t's in the same direction, but I found I only had to look at one hand and the other side would turn out just fine. It was like all the spacing and proportions of the letters translated from one hand to the other such that I would write better with the hand I wasn't looking at than I would if I had simply closed my eyes the whole time. I'm about three times slower writing with both hands simultaneously than with just my right hand.

A sample of the writing (more Simon and Garfunkel lyrics, this verse is from "Flowers Never Bend"):

Earlier today, I continued the experiment by writing backwards with my left hand and a mirror image with the right hand simultaneously. Sample below.

Finally, I tried writing upside down. Here's a nice trick to that; if you get confused as to which way a letter goes, think about which is normally closer to the last thing you just wrote, the line or the curve of the letter. For example: for "p" the line is closer, so you'd draw the line first then the curve (only now it's upside down). With an "e", you start close to what you just wrote and go away from it.

No doubt I'll come up with more strange brain twisters for writing (upside down/backwards/mirror image with both feet simultaneously, perhaps :P ) but so far I've been keeping myself entertained.

Touch Typing with One Hand

I am trying to figure out how to touch type with one hand. I think I'm doing pretty well, since I'm typing this very post with only my right hand. I don't know what prompted me to want to do this; perhaps it's my interest in doing things differently (such as trying to be ambidextrous), or maybe I had to try to type in a search while holding a phone one too many times. In any case, it's kinda fun.


My method and findings so far: I place my index finger on the "F" key and let my other fingers rest on the G, H, and J keys. This puts my hand right in the center of the keyboard and is convenient for finding my hand placement because of the little ridge on the F. I was somewhat surprised how little I had to think about how to get to the various keys. I have to stretch a little further, but I can find my way fairly easily. I suppose all the years I've been touch typing in general has given me a pretty solid idea of how the QWERTY keyboard is laid out.

Now, the main thing that feels really different from typing with both hands is how much more I'm using my little finger. Here's what I mean; my index finger hits 12 letters, middle finger only 3, ring finger 4, and little finger 6 letters plus the semicolon, comma, period, quotes, backspace, and enter. (I was hitting the "I" with my little finger also, but I was getting terribly confused with the I, O, and P, so I started just stretching my ring finger to get to it.)

Alright, so I wanted to see how fast I could type this way right when I was first learning. I did a control test by seeing how long it takes me to type a random page of a book normally, which came to about 70 words per minute. Then I typed that same page with just the one hand, and it came to a whopping 9 words per minute. My second try gave me 11 wpm. Yay! Never mind that it took me more than 45 minutes per try, I'm confident I can get it up to at least 50 wpm with a bit more practice.


More related thoughts: So one thing I noticed is that, unlike typing with two hands, I will occasionally vary which finger I use for certain keys. This has to do with which words I'm typing. For example, for the word "there" I will alternate between my index and middle finger for the "ere" because it's easier and more efficient than using only my index. This made me wonder how it might be possible to find the most effective typing pattern for any word? Or even better, the best keyboard layout for one hand? It would have to take into account not only the most common keys used, but the most common combinations of letters in a language and the fact that the little finger wears out faster than the others. Also, perhaps the thumb could be more useful?

Just a starting place for these thoughts, I'll probably start looking up custom keyboards now. I know a little about the DVORAK, but that's about it.

Writing with my Left Hand

I've been learning to write with my left hand. I want to be ambidextrous! For those that don't intuitively understand why this would be so cool, here are a few advantages to being able to write with both hands:

-if you start to get a hand cramp in one hand, you can switch to the other one
-you never have to worry about the annoying spiral in spiral bound notebooks getting in the way
-it's probably good for your brain
-you can confuse semi-observant people by writing with a different hand every time you see them
-if you break one of your hands you already know how to use your spare

I dedicated a notebook to purely left-hand writing. Almost every day for the past two or three weeks, I've been writing down all the song lyrics I can think of. I've even gotten to the point where I can take notes in class with my left hand! It just takes a lot longer (I'm at about 1/4 the speed of my right hand). Maybe I'll post pictures of before and after sometime. Right now it looks almost exactly like my normal handwriting.
