One-handed Keyboards

"HandyKey has

pretty neat! A variety of similar devices are summarized
on a page at
Stanford,
but aren't quite as nifty. " I think everyone on
earth wants a twiddler. If I had 2, I could type twice as
fast, right?
What if that waterproof keyboard company got together with this company? Just think of the possibilities...
The only real value for the RSI-afflicted here is that you can stop using one hand altogether while using the twiddler on the other. Also, you don't have the back-and-forth movement from the keyboard off to the mouse (but the eraserhead or even the glidepoint are better answers to that.)
Also note that while the twiddler is left/right symmetric, it is *not* otherwise adjustable; I've found a number of women with small hands who are unable to use the pinky-finger keys, just because it assumes similar reach and dexterity. A keyboard that was "handed" would be far more usable... you can of course define those keysequences away, but it cuts down even further on the number of single-press keys.
Still, they've always been good about publishing protocol information (5 years ago, way before it was "cool", I asked about it and the president of handykey faxed me the protocol, which eventually led to an X driver...)
At the risk of creating a whole new class of litigation related to repetitive neck movement, I suggest that we move forward with head-mounted pointing devices and do away with switching between the keyboard and mouse.
11 years ago I suggested this as my senior project and my professor just laughed. I still think it's a good idea. Add a button to the keyboard for clicking and dragging, but turn your head left or or right and up or down to move the cursor.
Want to move to another xterm without selecting it? Move your eyes, not your head.
Anyway, whaddya think?

Nonono: It's not to let you use the mosuse and keyboard tat the same time... it's so that you don't have to move your hand from the keyboard to the mouse and back, and to eliminate the strains of positioning your hands on the keyboard and the mouse.
It's actually not possible to use the keyboard portion and the mouse portion at the same time(if we are to believe the manual!), as activating the mouse sensor requires pressing a "mouse" button, and it redefines some (all?) keys to be mouse macros (left middle right button, left middle right double click, etc).
This is slightly off-topic, but is an Idea I had in response to reading the posts on using these on PalmPilots and da_penguin that wanted just a remote control... /what if/ you used a touchpad as the hardware (those mouse-touch-pads that Alps makes&sells) and hacked/wrote/coughed up a driver that would recognise Grafitti from one? Even with a hot-spot to toggle text-input/point-input? That would effectively work as the remote control.
I'm not saying it would be speedy input, but
How come we don't have gloves that read in finger movement. I thought they had already developed these for help with sign language. It seems a popular method of input in sci-fi, is the technology to expensive or something? So I just got through reading the first book of the otherland series. Sue me. :)

Has anybody used one of these to play Quake? It seems to me that it would be about impossible to run and shoot at the same time. Or is it just me?
I seem to recall a Dilbert comic like this. Dilbert is walking around typing on thin air. He sees someone else doing the same, and asks "Are you an engineer also?" The reply was "No, I'm an idiot."
You hold it like a Guitar neck or even a violin. People have been doing that without problems for many many years.
The number of chords on a n-key input device is .. n - 1) n!/i!(n-i)!. For a glove, n = 5 and the total is 25, which means you can handle 30 unique keys -- barely enough to handle the alphabet, if you assign one chord to be a toggle for shift. Adding "up" keys to the glove for the three strongest fingers (thumb, index, and middle) would give you enough keys, but I don't think it would be easy learning to chord with some fingers up and others down.
Sum(i = 2
What kind of typing speed are you getting?
There was an artical about VRgloves that used hand movement and position to type macros and letters. The guy who wrote it said that with these methods you could have several hundred possibles.
Sorry about the abbreviations... ran out of
subject space. Looking at all these chording
keyboards with macros drivers, it seems to me
that one could develop a keyboard driver that
works with a standard keyboard to enable chording
off the home-row keys, for instance, and use
the same ideas to enable macros as well. I had
a friend once who was blind, that's kinda how he
types. And braile has its own macros built in.
(like there's a special "letter" for "the")
Maybe that's just because I have large hands. Probably. The only person I have ever noticed with larger hands is former relief pitcher Dick Raditz. I would like to see a large hand keyboard. On a normal keyboard, there is no way I could get my fingers on the "home keys". Most of the time I use my right hand on the keyboard, but when typing a lot of text, I also use the left a little, for about the left third of the keyboard, with some overlap.

I own one. they are extremely finicky and harshly sucky in general. save your money. build your own.
The biggest problem with remapping keyboards in my opinion is that you
end up with something non-standard. That's ok if you always use your
own computer, but not fine if you have to use other peoples keyboards
as well. I already get annoyed if I go from a type5 keyboard to a PC
one; let alone have to go from a personalized layout back to QWERTY.
>> I work with a lot of boxes. mine ones are dvorak, other ones qwerty. I can type very fast in any one after the first 50 keystrokes...
There are different dvorak layouts for one-handed typing in addition to the two-handed layout.
your diff file seems to be backwards.
I have a twiddler. I also have VERY LARGE HANDS.
10.5" from thumbtip to pinkytip (measured). I tried the twiddler for several days, and actually learned to type very quickly with all lowwer case alpha characters. However, trying to use the thumb button for the mouse, shift, ctrl, alt and meta functions doesn't work because my hands are to big. My hands could wrap completely around the thing.
If anyone wants to buy my Twiddler (Hand Held Keyboard Replacement) Email me at Ben.Russo@GlobalOne.net. (Your hands should prob'ly be less than 9.5" from thumb to pinky.)
I've been using Dvorak for a yer or two now.
First, like another poster, I can still type just fine using Qwerty. I do tend to make more mistakes that I used to and thus have to backspace more often, but overall typing speed is reasonable. (Incidentally, I'm typing this message on a Qwerty keyboard).
Second, it's pretty easy to change keyboards back and forth. By using a handy URL off of my web page, I can change Unix and Mac boxes within two minutes.
Win* boxes are actually a little more annoying, for a couple of reasons, but if you use other people's Windows boxes very often I'm sure you could figure out a way to get instant Dvorak on those, too.
You can get a kernel patch for 2.2.X which enables one hand typing with standard keyboards using the number pad.
It is usable and stable, but docs and more countries are missing.

I'm at an early stage of development, if someone
wants to join and help, is welcome.
I think a much more elegant design is the BAT Keyboard. It's a chord keyboard design that does everything with seven standard pushbutton keys (not twiddly things like the twiddler).
If someone could take the BAT design, convert it into a high-quality membrane keyboard, and put it on an arm sleeve, that would be a great step forward for wearables.

Open mind, insert foot.
I wouldn't want to give up that much speed on my desktop. On my desktop I can use a full keyboard. If I had a wearable, I couldn't have a real keyboard. Thus a BAT design, modified to be wearable, would be a good thing even if it was slower.
----
Open mind, insert foot.
I doubt Windows users will buy this. When was the last time you saw one of them use a keyboard?
Should go over big with the AOL crowd.
I got to try out the Apache headgear at an air show some years back. Was very sweet... zero learning curve... wherever you look, the "pointer" goes. Do we get that neat Apache feature where whatever you click on gets... er... unrecoverably deleted, too?
On their website they admit that most people can only reach about 30-50 wpm. I already type 80-90 wpm on a QWERTY keyboard. I'm not sure I want to give up that much speed for the other benefits.

Well, I always thought the twiddler was neat. But I don't know if I'd buy one. I have too many questions and concerns.
I mean, every picture I've seen of someone holding one, has the hand bent back at the wrist. This is the *exact same* position that, when typing or clicking the mouse, is (at least partially) responsible for causing carpal-tunnel, tendonitis, and other repetative stress injuries. I know when I have bad typing posture or rest my hand on the mouse, I notice pain in all sorts of places throughout my hands and arms. But when I correct it, the pain stops. Have there been any testimonials about people who had typing-related injuries, but whose condition improved when they started using the Twiddler? Have there been any reports of people developing typing-related injuries *after* starting the use of the Twiddler? These are things I'd like to know.
Also, I don't know how it works. What is the keyboard layout like? I don't understand how so few keys are used to emulate a full keyboard. What do users' typing speeds compare to their typing speed on conventional keyboards? And they say it fits comfortably into both right or left hand? But what does that mean? Just 'cause it fits doesn't mean it's just as usable. Does it have a switch to make it symetrical, or does the left hand have to learn it reversed -- I don't see how *that* would be a good thing.
And what about drivers? That sucks. If I'm gonna buy a portable keyboard, I better be able to carry it with me and plug it into anything. I mean, couldn't they make a box of some sort that converts the Twiddler's usual signal to scancodes for whichever machine-mode (PC, Mac) it's in? And there could be two cords coming out the back -- one for keyborad, one for mouse. That would solve the problem of drivers; you wouldn't need any.
I'm all for a portable, low-stress input device for computers. But is the Twiddler really it?
I don't really know what the right answer is. Emacs would be okay if the typewriter-cursor keys weren't ^N,^P,^F,^B, which are nowhere near each other on oth QWERTY and DVORAK.
Emacs wrecked RMS's hands.

Headmounted mice have been tried, but it's not that accurate. What you really want, though, is eye-tracking.
Ooh, a sarcasm detector. Oh, that's a real useful invention.
Well, on my twiddler which is 4 months old, the buttons are not difficult to press, and I've got it to the point that it is comfortable to hold and use for a while without having to readjust constantly (which was an initial problem. Your hand does require training to find the right spot).
As for a chording scheme, the one given is logical for writing email or typing letters but is *AWFUL* for anything more geek oriented, like coding, using emacs or negotiating a terminal. I've worked off and on on a better one, but haven't settled on one yet.
The twiddler is pretty cool. It has been around for a few years at least. I've had one for 6 months now. It does not replace the keyboard for me, yet, but I use it on my laptop (and keep it in the laptop case) when my wrists start bothering me.
It is a chording keyboard, which means that most keystrokes are done via a combination of keys, which is more difficult to learn than the single keystroke -> character mapping we all know and love.
However, the mappings are completely edittable under most drivers. The driver I have (which I keep meaning to hack on to improve) for linux is completely customizable as are the ones for winXX and DOS. There is currently no working mac driver and the palmOS driver leaves a lot to be desired (is not customizable). The palmOS cable also requires a bit of soldering to build.
The twiddler is worth it if you are looking for a decent alternative, but requires a lot of time to get up to speed and a bunch of hacking to get a decent driver under a unix.
The biggest change I've heard is that it is wireless (using RF, not IR), will have a direct to PS/2, not just serial, connector and have the option of coming with a pilot cable.

Its a pretty cool gadget.. although i highly recomend you get a better layout than the
original.. there are several floating around
on the net... unfortunatly its a little bothersome
for me to use full time because my fingers get sore but for a laptop its quite a bit more convienent than a keyboard sometimes...

Of course, I don't see how this could work unless you were also doing very sophisticated sensing of your position in space (e.g. with sensors on your legs) since you would be in constant motion. I guess you'd need some goggles to see the dang keys of the virtual keyboard, too . . .

This was in February's Linux Journal. The article about wearable computers. Dr. Mann talks about the evolution of the WearComp. You can check out that research and innovation at wearcomp.org What I want to know is, who uses this? And how easy is it to learn? Joseph Elwell.
The twiddler is way old news. It's also quite costly at $199.00. (Well, so are the other hardware based single handed/alternative keyboards).
The stanford article is funny, considering the fitaly on-screen keyboard for the palm as a one-fingered keyboard. Funny, wouldn't palm's builtin onscreen keyboard count too? And all the other various on screen keyboards? Heck, with
caps lock a regular keyboard can be done single
finger with the same functionality, albeit not
as efficiently.
I have used Dvorak for one year and am very happy. My hands no longer feel like they have been pounding rocks.
Unfortunately, Dvorak makes one handed typing slow since the keys are strategicaly arranged to be alternating sides between keystrokes. Dvorak does not make a good hunt and peck layout.
aren't there any cheaper Twiddler-like thingies out there? I'd _love_ to have one, but I don't really feel like shelling out a month's worth of scholarship for it :-)

Overall, I thought it very neat, and would like to see it further developed, but it does not look like they have made any improvements in the hardware over the years. A better shape, softer touch buttons, and a built in spot for a battery (as opposed to siphoning power off the keyboard port) would make it potentially very nice.

HandKey has been building the Twiddler for a years, this particular site has been referenced in comments by just about every article on wearables to appear on /. Just where is the "news" here?
Yeah, I've been using one for my wearable for more than a year now.. The ppl over at MIT have used them much longer.. It's a great keyboard, but for a normal PC, I'd reccomend a normal keyboard, unless you for some reason are unable to type with two hands.

Hokey statistics and ancient misconceptions are no match for a good thought in your head, kid!
All my hand problems disappeared when I ditched QWERTY and rolled my own. There were plenty of good Dvorak layouts out there, but I thought it was kinda neat. (Note: I had no *serious* trouble, it was just starting.)
Of course, I don't type as fast (yet), and the idea *is* a bit crazy, I admit. But with Linux, everything is possible.

The hardest thing about switching keyboard layouts
;-)
is when I run my own keyboard on QWERTY. Normally, I `feel' how the keyboard is, and then (unconsciously) decides which keyboard layout to use.
I still write faster in QWERTY (517 chars/min on real text), but it's so geeky, I just have to continue

I did what the company said would be the standard motion for moving the mouse, and I could tell that even ten minutes of such activity would be hellish on the wrists. I'll wait for monocle mice, equivalents of which have been available on the AH-64 Apache since the mid-80s.

Ive had one since December 25th, 1998. It is a very nice tool, my wearable is almost complete now.. just waiting for UPS. Beware the drivers for it though, the drivers on handykey.com do not compile and the binaries do not work with 2.2.x :( But there is an alternative, newer versions of GPM work with 2.2.x.. but unfortunatly also means it does not support X :( [although, it might be hackable to wrap GPM > X] The default layout for both of them obmit the "/" key though, so you might wanna hack the configuration files as well :) Good luck for anyone that gets one, btw.. I could type 4wpm within the hour of getting one.

I am doing the same thing, only under win98 (DVD support ya know) - I picked up a keyboard called 'VersaPoint' from InterLink Electronics. It is a bit pricey, but uses what they call "Broadband IR" - whatever it is it works great. You can aim the keyboard at the floor, ceiling, or a wall 20 feet away and the receiver still catches every keystroke.
The keyboard has a builtin touchpad (ick) but the model I got came bundled with a "RemotePoint" remote mouse which works great.
Both work flawlessly with Linux, no special drivers are required. The IR receiver just has a mouse and keyboard plug.
Only problem is the keyboard is a bit squished into a smallish form factor - but for surfing it's fine. I wouldn't write a novel on the thing.

Hmmm, this thing and the way it is marketed just lends itself to dirty jokes. Just be ware that too much "Twidling" has been reported to cause hairy palms. I have tested this theory for the past several years, but results are inconclusive. There is no excessive hair on my palms, but maybe that is because of all the "Twidling". Hmmm, I guess I will never know.

I most definitely prefer a smaller number of keys (the BAT), but the twiddler is much nicer to hold, while the BAT is table-bound :(

I posted this article NOT to break any ground...these things have certainly been around for awhile now.

I do think that there are likely quite a few people that haven't heard of them yet, and seeing as how they (the Twiddler, at least) can be used with palm pilots, i thought some people might find it interesting as an alternative to a stylus
they are quite pricey too, though. But after all, those who can afford $500 for a Palm can almost certainly spare a bill or two for a nice input device

You'd have to modify the drivers or have two drivers running mapped to different com ports. If you want to switch hands, there is a keyboard y-splitter, and I'm sure you could find one for a serial port too. Standard typing speed goes from very slow up to 40-50-60+ wpm for the very fast (and those who have nice macro layouts), but those speeds usually aren't reached until months of usage (or so I've heard).
Wearables Central, almost everything you would want to know about wearable/ubiquitous computing (or a link to it).
Looking at the picture on the main page (a someone's claw-like hand pressing the keypad against their palm) makes my wrist ache. Using this thing for an extended period of time can't be good for you - although I suppose you might be able to switch it between hands from time to time. Has anyone seen any studies on the ergonomic benefits/costs of these devices?
Old or new, it's pretty cool.
The site says the keying is based on chords. I dunno. I played the cello for a while-- will that give me an advantage in using a left-handed version?
I don't know how excited traffic cops would be, but how about using this in conjunction with an Empeg system? Type while you drive. Sorta like talking on a cell phone.
From the description on the website, and the comments I've read, it seems to me that you'd be more likely to drop the thing trying to get something typed than increase your productivity. A good idea, but maybe they should consider making different models for each hand, and maybe a strap/glove to keep it on your hand so you can relax it every once in a while.
I know that my twiddler is not exactly easy on te wrists!
Basically, my opinion is that if you're interested in wearable computing the twiddler is the best there is. If not, there's almost certainly something more comfortable and better suited. Even silly "in car" apps could probably find something more comfortable/flexible than a twiddler.

I am looking for more of a 'remote control' type device. I'm building a Linux box into my home enertainment center for: MP3's, couch surfing, gameing, ..etc.. I want a cordless, trackball mini-keyboard all in one. The keyboard doesn't need to be designed for speed, there will be very little keyboarding for this application.
Any one know of such a beast??
(Sorry about continuing the off-topic stuff, but the shooting pains in my hands made the previous post stand out.)
Do you know of any good resources for rolling one's own keymap? The keyboard / terminal HOWTO was less than totally thorough, IMHO. I was especially intrigued by the (patented) half-QWERTY keyboard mentioned in the article. The design sounds easy-to-learn, but how does one make the space bar sticky?
I'd be happy with an RTFM, as long as it pointed to a good FM.

I saw a much cooler handhald keyboard than this in a PC mag once, IIRC it was available for Psions and PCs and it comprised 5 switches in a thing you gripped in your hand, you made the letters using different combinations of buttons. The cool thing was you never had to move your fingers, so touch typing was a no-brainer.
I will try and dig out a picture or URL or summat.

Surely if you treat each button on the device as a binary bit, you get 2^5 combinations.
This gives 32possible values.

Sounds like a variation on the old Microwriter from the '80s. It never really caught on, although its supporters were very enthusiastic and claimed that it was easy to learn how to use.
:^)
Me, I just don't like the idea of using chords to input text. Hmm, thinking about it I suppose using a shift or control key counts as a chord, so I use them already. Oh well, what's that quote about consistency and small minds
What I want to know is, who uses this? And how easy is it to learn?
I tried it, and the main problem that I had was that it was very very awkward to hold and type on. It was exactly the same feeling as trying to play a particularly tricky chord on a guitar. It comes with a wacky strap that you use to tie it to your hand, but it didn't help me much. You feel like you have to balance it in place with your thumb, but you also need that thumb to type with. I'd love to use a keyboard-alternative, but this wasn't it for me...
From what I understand, there's a lot of research going on in this field right now, especially with the eye-tracking. I can't wait, personally, but the cost would probably be prohibative.
I remember in CGR something like five years ago there was a special on RSI and possible cures. They showed a keyboard with only five keys, positioned ergonomically so that if you were to simply lay your hands down on the device, your fingertips would touch the keys. Any keypress could be simulated by a combination of these five keys. Though though to learn, apparently with practice one could type without any speed loss. Anyone else have recent info on this thing?
If I recall, the Twiddler made its first public appearance at Comdex in 1991 (maybe 1992). I rember seeing it in Byte magazine around then. It doesn't seem to have changed at all over the years.
The article seems to say that the goal is to be able to use the mouse while typing. I want to know why? I can't think of any application where it would be beneficial to type (note: that doesn't mean use the keyboard, it means type) and use the mouse simultaneously. For things like Quake, sure you want to use the mouse and the keyboard at the same time, but you're not really typing. Also, you can remap the keys so it's really not an issue of moving your hand from the keyboard to the mouse and back ('sides, you'd get fragged to pieces). I can understand the desire to get rid of issues like having to (while typing) use the mouse to activate a window or something, but why not replace the mouse instead of the keyboard?

I heard a rumor a full year ago that Handykey was working on a new version of the twiddler optimized for PDA's such as PalmPilot. Currently, I believe that there are power supply issues, and the "mouse" functionality is not especially useful. The current model is also somewhat bigger than it needs to be - taking a centimeter off of length would be significant for PDA users. Has anyone heard more about such rumors?

I always found that reprogramming the keyboard was harder than remapping functions in an editor. And if you are using vile, vim, or another open/free software clone of vi, you can easily hardwire different keystrokes.
The biggest problem with remapping keyboards in my opinion is that you end up with something non-standard. That's ok if you always use your own computer, but not fine if you have to use other peoples keyboards as well. I already get annoyed if I go from a type5 keyboard to a PC one; let alone have to go from a personalized layout back to QWERTY.

The link to the one-handed qwerty 'boards on the Stanford page (forget which one) looked pretty nifty, nifty enough that I decided to play around with xmodmap and see if I couldn't piece together a simulacrum of it. It's still a preliminary version at the moment, there are still lots of bugs to be ironed out, but it's up right now at what will eventually be my homepage once again. I'll work on the right-handed version when I get the left ironed out.
