[cctalk] Re: Computer Museum uses GreaseWeazle to help exonerate Maryland Man

As for what I said of morphing shape of keycaps: I think I recall a MacBook circa 2018 having something like this - at least one special row near the top? It had programmatically controlled colorized symbols, and was a small touch screen. There's also been anime depiction of "projected keyboards" -- the keys are projected onto a surface, and some AI-assisted camera monitors your finger motions and is able to compute/interpret what projected keys are being pressed (and those projections of course can be of any symbol shape). I recently came across the old H.S. yearbook of my grandmother from 1940s, and it had a report/atrticle of a typing-class (all female; it mentioned there were two males but they dropped out of the class), and the young ladies had won a regional contest at a blazing speed of ~20 wpm. I recall actually using a typewriter long ago, and I recall there being an implicit speed limit because if you went too fast, the metal hammers would bind up -- so I imagine in the 1940s the mechanical design of consumer/H.S. grade typewriters maybe wasn't the best (so 20wpm then maybe was reasonable). I remember even by the late 1980s, "most" people still didn't know how to type very efficiently (as "most" people still didn't even have a computer at home). If I had to guess, I'd say in the 1980s the average WPM was still ~20, while today I suspect it's over 100 wpm (be it either thumbing text messages or actual typing) -- that's just a guess, no research. But now-a-days, I don't ever see any "Typing Class" specific classes at H.S. or college. Collectively or in aggregate, we've "all" learned that skill at a sufficient speed and accuracy. It's like the width of roads -- or the width of lanes within a road -- we're forever stuck making those about the width of two horses pulling a carriage. But if your keyboard was some kind rubix-cube type device (which I think I had once seen such a thing, as a keyboard) -- maybe some specialized training would be needed again. But I guess to be worth it, it would have to show trained operators can get some kind of orders-of-magnitude improvement (300+ wpm), and maybe with the "speed of human thought" that's still not necessary, because we're still going to pause and think in between typing. Good point in stock brokers using some special keyboard -- I wonder if perhaps not just for speed, but perhaps also security? I wonder if a kind of "morphing organic" keycap keyboard might help in password/identity verification? (sort of like private keys -- instead of typing a password, what if a few keys are configured to show your chosen codewords mingled in with a few random words, and you just press the key with your codewords in the right sequence -- afterwhich the keys revert to their normal purpose? not sure if that really helps, since the keyboard is then showing portions of your password -- maybe the keycaps could be angled or polarized to be less visible from side angles {like screen privacy things}). I recall looking up the origin of the QWERTY keyboard - a rough beginning in 1874 but rather refined by 1878, and having essentially the same layout we have today. So it's neat to me that for all the advances in computing processors and memory -- but we're still basically using a typewriter as our primary input :D I'm not sure if any alternative can really give any orders-of-magnitude improvement to the average user (in speed or accuracy). BUT, it's really hard to think outside the box on a 150+ year old design that's so well accepted by the general public -- like the pen/pencil, it's still a good intuitive design. -SL On Wed, Jan 25, 2023 at 2:53 PM Bill Gunshannon via cctalk < cctalk(a)classiccmp.org&gt; wrote: > > On 1/25/2023 3:22 PM, John-Paul Stewart via cctalk wrote: > > On 1/25/23 11:53, Steve Lewis via cctalk wrote: > >> And back on the stenography-keyboard like thing -- what about morphing > >> keys?
