writing about keyboard

started to trickle into actually amassing and writing about Keyboard History ⌨.

Keyboard History ⌨

Added tens of photos in past month, and started to get a sense of keyboard evolution since 1960s. Keyboard history is a black whole. Well actually, not really. Math is, a hole.

Actually, working on keyboard makes me feel bad. It's petty. A petty thing. Writing comp lang tutorials is bad enough. A dismal petty fak complexity mostly of social causes due to programer idts faks. Dear god, when am i gonna be a real mathematian? God: neva!

history of alt key

https://www.reddit.com/r/emacs/comments/9ipnug/til_alt_and_meta_keys_are_different_keys_in_emacs/

The history of the Alt key is a mystery to me still. I bet Marcin Wichary https://twitter.com/mwichary knew the answer.

recently i learned Meta key first appeared on the SAIL keyboard. (hope am correct) I'm not certain the date of SAIL, but must be between 1963 and 1974. SAIL keyboard also has a key labeled ALT. The SAIL became Knight Keyboard and became Space Cadget and other lisp machine keyboards. But in later ones, some of them has Alt Mode instead of Alt. Some also have Alt Lock. But some don't have any type of Alt key, e.g. PN 364000, PN 365407, and Xerox 1109.

it'd be nice if someone can tell us the history.

Also, the Alt on SAIL keyboard is the earliest Alt key i've seen.

The first other apart from lisp line that has Alt i found is: IBM PC model 5150 Keyboard, 1981

now i think the entire modifier business started on lisp machine keyboards, except Shift and Control. The meta alt or super hyper evolved into Mac's Cmd and Option. Alt Graph key may also be evolved from the Alt on lisp machines. The Window key of Microsoft may be inspired from Mac, and Microsoft invented the Menu key (but may be inspired or copy from some Xerox stuff.) Also, keep in mind that the way Alt works in Windows is not the typical modifier. When pressed by itself, it invokes menu, as a leader key of a key sequence. When pressed with other, it call commands, and can also insert chars similar to Alt Graph key. .

todo down the road:

Touch-Typing in Japan

In Japan, the touch-typing rate even among college students is 15 percent. This rate is much lower than the 85 percent of American college students.

yes, the trackball am refering to is same as you are using, the Logitech Trackman Marble. here's my review and photo of me with it Logitech Trackman Marble Review yes, it's 300 dpi only. i've been sloppy on reddit here.

there is some debate in the comment here you might find interesting Trackball vs Mouse, and How to Choose a Trackball

and i think a “scientific” way to judge is to play osu with different devices. i have collected video of them here Test Your Mousing Efficiency!

mouse and trackball, dpi, internal acceleration?

reddit discussion https://www.reddit.com/r/Trackballs/comments/97abhf/the_physics_of_internal_mouse_acceleration_or_are/

nah, i don't think this makes sense.

as far as i know, no trackball has internal acceleration. Actually, i don't actually know a mouse that has acceleration built in, though i've heard they exist.

there's lots myth about this topic, and seems to be a perennial obsession since optical mouse around 1998 or so.

polling rate does affect cursor speed. e.g. if you have a gaming mouse, and you set polling rate from 1k hz to 0.5k hz, you can notice a speed up in cursor speed, even the dpi is set to 1200 and didn't change.


on linux, the os acceleration is typically, when certain distance is reached within a given time, then multiplier kicks in.

so the curve looks like, beginning with a small flat segment, then a straight line going up. (x axes is speed, y is distance traveled)

i think ms windows acceleration does the same, but not sure.

trackball dpi has very diff effect than mouse dpi. The larger the ball size and smoothness (e.g. can it spin), the more dpi it feels. imagine a maglev ball that can spin for 10 seconds and ball size of palm like in some arcade games. such trackball, even technically 300 dpi, will feel like 3000 dpi.

you can see many comments here (my page) Trackball vs Mouse, and How to Choose a Trackball

and What's Mouse DPI? Does DPI Matter in Gaming?

for lots discussions. There are many nerds who created custom acceleration software for Microsoft Windows. But i think it's not worth the effort. Just get a nice mouse or trackball with good enough dpi, and arguably turn on acceleration.

to trackball or not trackball

reddit discussion https://www.reddit.com/r/Trackballs/comments/95h5t1/is_there_any_objective_evidence_showing_the/

nah, i don't think there's any evidence at all.

i've read a lot articles about trackballs , and am obsessed about how it compared to mouse as a input system, since 1990s. i actually didn't own any, untill few years ago.

now i've used a few trackballs daily for a few years, and i'd say, nah.

there are some wiz kids who use trackball more proficient than mousers at FTP shooter. it's on YouTube. i'll find the link if you need.

I also conclude, trackball can't be controlled as precisely as mouse either. e.g. when you have to say aim at the close window box quickly.

one easy test is to write your first name in print on screen with trackball and mouse, as fast as possible. Am sure, vast majority will be more accurate with less time by using mouse, given same amount of time/training with each device.

trackball is just in general easier to use, and easier on hand.


@/u/SynBogaNajwyzszego

that video https://www.reddit.com/user/SynBogaNajwyzszego is most annoying. how do we know he's using trackball? well, maybe trust can be established from his reputation or his other video recording showing trackball in parts of the screen... but still, yeah, we need to see that video.

the Logitech Trackman Marble is ancient. I have it. Even last month, i tried to use it again, but decided to put it away. The resolution is too low. (something like 800 dpi?) yes, i have acceleration on. but i also noticed, on the Mac, it makes the cursor jump.

(one interesting thing about polling rate i discovered is that, when OS acceleration is on, higher dpi can make the cursor moving speed significantly slower. here's my story: few months ago i got logitech g502. it has 1k Hz polling rate by default. I have acceleration on. And i set dpi to 1200. And i have another logitech mouse plugged in, the g600, also set to 1200 dpi but polling rate at 250Hz. Then, i noticed, the g502 is a lot slower. If i reduce its polling rate to 500hz, then it becomes faster. while doing all these, i have also my trackball plugged in, the ancient logitech trackman marble. The trackball becomes very jumpy sometimes (when cpu is busy or something) when acceleration is set to highest. )

been thinking that too. Something like Akai MPK Mini could work. there's already midi/usb/key interface. @batchout has done it. and there's steno/pianotext/michela as “layouts”. I've been really wanting to do. think it'd be most efficient. Not sure what's the long term effect on hand.

am thinking, would take ~6 months to do this project. e.g. so others can just buy a mini controller keyboard, install software, and read tutorial, as complete PC keyboard replacement, including for ctrl etc shortcuts. (and maybe 2 months to become fluent)

as a personal project i think it'd be very interesting. it can include many ways to do emacs commands. i think the downside is, effort cost is big, but 0 commercial prospect, cuz most people don't want new input system. e.g. maybe 1% of emacs fan might actually buy/try.
