EyesWideOpen writes: "The New York Times (free reg. req.) has an article about a guy who has invented a one-hand keyboard that really isn't a board at all. The 'Stealthy Keyboard', which is in the prototype development stage, is designed to fit in the palm of the hand and uses the fingertips, the middle of the fingers and combinations of those to generate characters. More information (white paper, downloadable engineering plans, photos, etc.) can be found on this website." Inventor John McKown adds "The kit includes (open) source for the firmware. The code is for a PS/2 port but a USB version is slowly progressing."

    • whoa.. I know you were just kinda kidding, but really, that'd be awesome. On one of my mailing lists, there was recently a post about a guy who could multitask his body/attention. He'd be doing one thing on the chalkboard with one hand, doing a completely different thing with the other hand, blah blah, I found the email so here it is:

      (I take no responsibility for what I'm about to post - what you do with the following information is your own business. Be warned that you could seriously screw up your mind...)

      This Multiple Mentalism course is a revised version of the course originated by Harry Kahne in the early 1920s. At that time he was billed as The Incomparable Mentalist and The Man with the Multiple Mind.

      He often demonstrated his ability on stage by doing six different mental operations simultaneously. His platform performance entailed standing in front of a large blackboard with a piece of chalk in each hand while conversing with the audience. There was a newspaper on a music rack in front of him. He began reading the headlines while writing upside down and backwards with one hand and mirror language with the other hand.

      At his left was another small blackboard on which appeared the number 28,642,981,673 --- which was being divided into five unequal parts --- these figures he began computing at the bottom of the large blackboard. To his right was another small blackboard on which appeared seven columns of figures which ran into the millions. These were being added and notated as well at the bottom of the larger blackboard in front of him.

      This was Harry Kahne's demonstration of doing six things at one time, i.e., reading, transposing, writing backwards and upside down, holding a conversation, adding and dividing. These six separate processes actually involve fourteen distinct operations, i.e., hearing questions, answering questions, reading a newspaper, transposing what is read, transposing spelling, writing with right hand, writing with left hand, writing upside down, carrying six different thoughts in mind, retaining questions, retaining figures for addition, retaining figures for division, proving previous work and controlling all other physical actions of the body --- such as walking, bowing, etc..

      At the end of Harry Kahne's demonstrations, people often asked him, "Do you really believe that nearly everyone can learn to perform the amazing mental feats you demonstrate? Is my brain capable of carrying on four to six independent functions at one and the same time, as yours is? Isn't the ability to master your training confined to well educated people?" When answering, Harry Kahne admitted he had only an average brain to do things no other man in history had done. Education had no bearing on it.

    Now if someone would only invent a one-handed mouse...
    • I have had a Twiddler (made by Handkey) for about a year now. It is a one-handed keyboard and mouse. It has worked well for me, and I wonder why this article proclaims the technology to be so prohibitive.

      The Twiddler has 15 keys. You press any combination of three keys to type any character or series of characters. It's a little bit slow, but it works well. As for the mouse, the Twiddler had a stub-style pointer often found on laptops.

      I can get speeds about as fast as on my desktop with my Twiddler. I have to hit 3 keys to type "A", but I also hit 3 keys to type my name, "Drew Bradford."

      The Twiddler did cost me almost $200, so I can see how a lower-priced option would appeal to consumers, but the technology and products themselves have been on the market for quite some time.

  • Like we've never seen one of those [tifaq.com] before.

    So, why exactly is this different than other types?

    • Previous chording keyboards haven't been very popular. How is this one different?

      One big reason is that the typing fingers don't grip the unit and don't participate in retaining it within the hand. Trust me; this makes it much simpler to use. It's hard to type with fingers that must grip something at the same time. That's why the only portable one-hander you can buy at present, as far as I know, has a big, ugly, wrist strap . Another reason is that the fingers are never far from their relaxed positions. They don't have to curl tightly, which quickly becomes tiring. This keyboard is small enough to be mostly hidden by the hand so it's not so geeky. Since there's no strap, it can go in and out of a pocket quickly. When you actually get one in your hand you see it's great fun to type so casually and with so little effort.

      Looking at your link- and looking at his site the differences seem pretty obvious in regards to size and cost.

    • Amazingly, it's explained in the article! Imagine that!

      One thing that he says might be original (he hasn't seen it before) is the typing two keys with each finger. Beyond giving eight bits of input (Mmmm... a byte of input), is this unique? It seems like it wouldn't work, but he even acknolwedges that it seems odd and works quite well. It certainly allows for macros and/or a normal share of buckybits (Alt, Control, Shift), something I've never seen in a single hand chording keyboard without having to shift fingers or thumb.

    • of course we have - but thats not the point. We have all seen many things that are similar... but in this instance we have yet to see one that is comfortable and works well for the masses and is something that can become integrated into our daily lives.

      this one actually seems to fit the bill more-so than many others, in that it is something that you can have *in* your hand as you walk around and do what ever.... a very good interface to the wearable.

      if you follow the link that you have in your post you see that the others are sitting on a table - the main design feature of the ones you reference is the *chording* - whereas in this design the major feature is the ergonomic usability and portablity which is based on the chording keyboard. Its focus is the application of chording - not the development or creation of.

      so - I think that this particular incarnation of the chording keyboard is very practical and I am going to try to make one myself.

      I do a lot of CAD work - and although I am extremely fast when it comes to typing with my left hand... there are just some things that require both hands on the qwerty - which requires that I lose time drawing by having to let go of the mouse - then grab it again... also one thing that makes CAD'ing less efficient is that flat keyboards are difficult to be very precise when hitting rapidly. Requiring the repeat of commands sometimes as many as three times (with requisite swearing - and hitting the keys harder and harder each pass until the damn machine listens to what you are trying to say)

      • "of course we have - but thats not the point. We have all seen many things that are similar... but in this instance we have yet to see one that is comfortable and works well for the masses and is something that can become integrated into our daily lives."

    I know gaming is probably one of the last things a keyboard designer should consider, but in this case it poses an interesting question: how hard is it to press multiple keys at once? I guess this applies outside of gaming as well. If you use both the middle of fingers as well as the tips, is it easy to press them both? I know for my gaming I need about 15 easily accessible keys. With 5 keys, and all combinations of those you get quite a few more than 15 keys, but I dont want to have to stop running forward while I switch weapons. :)

      "It's hard to type with fingers that must grip something at the same time. That's why the only portable one-hander you can buy at present, as far as I know, has a big, ugly, wrist strap .

    This is a fine example of why patents are often a tremendous resource to the technical community. Go download the patent from the USPTO and you'll find the blueprint on how to build one of these yourself.

    Patents are in a way the source code for an invention. By law, they must be detailed enough to allow one skilled in the arts to reproduce the invention. Without patents, inventors would be forced to hid the details of the implementation of their invention (or even the entire invention) from others. With a patent we can have all the details on how an invention works and the inventor can still be protected if he or she wishes to sell the invention. Remember, a patent doesn't prevent you from building something as long as you don't do it for profit.

    Why the slasdot community is so hostile towards patents in principle I shall never understand. Sure, in practice there have some screwy patents issued that shouldn't have been, but in general patents spread rather than restrict knowledge.

      "Slashdot", inasmuch as it can be said to have an opinion, is hostile to software patents.

      In fact, many of us against software patents are just fine with mechanical patents, which is after all where patents came from. However, your own message provides an excellent argument about why software should not be patented. When software is patented, it does not provide enough information to allow one skilled in the arts to reproduce the invention, it only sorta/kinda describes it. It does not provide all the details on how the software works. Read, for instance, the Amazon one-click patent, and then try to implement it. You will find that there are hundreds, possibly thousands, of unresolved issues in how exactly the system should work and persist data.

      In fact, patents should really only cover source code. Source code would meet your criteria for the goodness of patents. Source code is already protected under both copyright law (no matter what), and trade secret law (if the company so desires). Why should software be patented, if none of the legitimate advantages of a patent derive from that act, since those advantages and more are covered by the copyright system, yet we get all of the disadvantages that we have seen in software patents (ambiguity, unfair patent grants, patent land grabs)?

      If you can answer that question with some degree of usefulness (i.e., applicability in the real world, rather then vague sweeping claims of potentially hypothetical advantages based on pre-conceived notions, which is all I've ever seen in software patent's defense), then maybe you can ask incredulously why Slashdot is so against patents. Personally, after several years pondering the issue, I don't believe there is an answer, which is why I don't think software should be patentable.

      For all the reasons you mentioned, and a few others (such as the fact the patent is of limited duration), I think that patenting the keyboard in question is totally legitimate. All the posters claiming "this has all been done" to the contrary, there are some legitimately clever and new ideas in this design that deserve protection before one of the established companies steal them from him. Maybe the ideas are dumb and won't work, but he deserves the shot in a fair market to find out whether this product can sell.

      (For those who claim this issue has been done, find me a product with all the characteristics the guy enumerates on his site, and maybe I'll listen then. In particular a chord keyboard with the fingers in neutral like that, that is an excellent idea that apparently isn't obvious, seeing as how no commercial product has done it yet.)
    • That's the theory behind patents. Unfortunately, the theory is seldom achieved. Most patents aren't detailed enough to allow one killed in the arts to reproduce the invention. Most often, inventions ARE obvious to one skilled in the art (because patent examiners aren't skilled in the art). And most often the best way to make money from a patent is by building the thing.

      And I haven't even gotten into submarine patents, which totally subvert the process you described.

      Big deal. There are plenty of one-handed chorded keyboards around, with minor differences in shape and major differences in layout and chords.

      Having a patent on them is self-defeating--why would anybody want to invest their time and effort in learning a patented input method when there are plenty of free ones around?

      Remember, a patent doesn't prevent you from building something as long as you don't do it for profit.

      There is no "non-profit" exception for patents. If an invention is patented, you are not permitted to build it for any reason without a license from the patent holder: not for research, not as a prototype, not to enhance it, not to try it out, not for education, not for fun.

      Why the slasdot community is so hostile towards patents in principle I shall never understand.

      Perhaps that has something to do with the fact that you don't seem to have a clue about the patent system. As someone who actually holds a number of patents, I can tell you: they are a useless waste of time and money. Most small inventors cannot easily afford them or prosecute them, and large companies just use them to keep innovators out of their markets. The overall result is bad for consumers and bad for inventors; only lawyers and large companies really benefit from the system (and the politicians they give lots of money to).

  • Hello,

    I've been working on a one handed keyboard that uses hat switches..., fits arround a PDA, and uses an IBM or Toshiba style pointing stick where the thumb is.

    The hat switches can fit on the other side of the knuckle, and can be moved in many directions.

    (think serations of a knife with hat switches in the dips)
    the points will protect the keys.

    The hat switches are very short.

    you can either look at the PDA or not to type.
    you can use the thumb on the same hand to control a mouse.

    I've been thinking about this for a year or so...
    I don't wish to patent it, however I do wish to see it come about... and want to attack anybody else who pattents it.

    You may barrow this design as long as you do not claim exlcusive rights to make it.

    Of course, my Morse idea would take some learning if you didn't already know Morse.
  • but I don't think I can use this device, as I only know three chords.
  • Douglas Engelbart, father of just about everything 'modern' in computing, showed a chord keyboard in 1968. Do a google search for 'chord keyboard' to see how many other people are doing stuff, or 'chord keyboard douglas' to find out stuff about D.E., including RealMedia of his 1968 demo.
  • I remember seeing ads for a one-handed keyboard in the computer magazines back in the early 80's. It was dome shaped, with two buttons for each finger and several for the thumb. IIRC, you had to basically memorize the binary values for the ASCII table to use the thing.

    Hmm. . .to get a character with this keyboard one often presses many keys at the same time to make a "chord" and produce a character.

    Can you imagine the insanity editing in Emacs would be? :). M-> for end of buffer or C-M-w for append next kill to last. . .do we have that many fingers?
  • I'm sure I heard years ago about Stephen Hawkins using something similar...

    I do see that there are some differences, but I can't see anything to suggest this is revolutionary.

    Personnally I would prefer to be able to input text using my apaulling hand writing (spelling included), maybe a A5 sized tablet with a full active screen, powerful enough to display all marks made immediately on the screen, thus aiding input.

  • I've always been intrigued by the Twiddler, but have been a little leery of the potential for carpal tunnel syndrome from using it (not that thousands of people have already gotten carpal tunnel syndrome from using two-handed QWERTY boards, but I haven't, yet).

    This device looks like it might conform even better to one's hand than the flatter looking Twiddler.

    What strikes me, though, is that the ultimate in one-handed keyboard comfort would be to customize the shape according to individual hands.

    Once you get the basic electronics down to size, just have people go to sleep with some kind of goo in their hands that will harden into a shape that is natural for your relaxed hand.

    Haven't joysticks come up with sufficient touch pads for emulating a full QWERTY board yet?

    ...not the other way around. This approach gets rid of the physically stupid part of keyboards, but it doesn't address the big learning curve for something so basic. If anything it seems like it'd make the learning worse, because one key != one symbol.

    Example: In order to pare the number of keys, all these designs resort to "Chords" -- multiple keys hit in combination, or in sequence, to produce a result. This design gets different results from your fingertips as opposed to pressure with the middle of your finger, too. So how many hard-to-recall combinations of left-thumb-tip with right-index-finger knuckle are we going to need to remember to avoid hitting ctrl-q when we meant "Q"? Not the system to learn on the laptop where you keep all your contact info, right?

    We're past the point where we should be teaching ourselves elaborate new routines to accommodate new technologies. The Palm handwriting system is a good example of how crappy that model is; I can't stand that the OS is trying to make me learn a new way to write "T" as a capital letter. That's just wrongheaded. The technology's supposed to be conforming to us, and that's not just a physical thing.

    • Graffitti is precisely the way we should be going. I know, I know you want to jack your brain in and all that but for now things like Graffitti make the most sense.

      Your capital T curves up, mine looks like a T Square, his looks like italic script, hers looks like a small T anyway. How is a computer supposed to know what you're talking about? (See also The Newton)

      Giving you the parameters with which to work in is VERY MUCH the computer way. Despite what you may think we HUMANS must CONFORM to the COMPUTER all the time. (See also Programming.)

      I mean Hell just look at spelling, none of it makes sense. (See also ghoti == fish)
      • "Your capital T curves up, mine looks like a T Square, his looks like italic script, hers looks like a small T anyway. How is a computer supposed to know what you're talking about?"

        The same way other humans know.

        Only faster.

      You learned to read and write as a child, didn't you? It's simply a fact of life that to communicate you have to learn things that aren't neccessarily intuitive.

      Who's to say that using chords is any more complicated than a standard 101 key board?
    • You are partially right, we should design things to be as simple as possible, but we cannot design them to be simpler than is possible. When you come up with a simpler, easier to learn one-handed keyboard, I'll buy it.

      Until then, a learning curve is a fact of life. Adapt or die

      When I started writing math intensive papers, I learned LaTeX. There were easier to learn ways to do what I needed(word would do all of it from drop down menus, for instance), but none of the others could match the input speed I had with LaTeX(pure typing, no mouse), and none of the others gave me as much control as LaTeX did. I gladly traded time put in mastering the technique and overcoming the learning curve in order to get that speed and that control.

      I hate it when interface designers make things more complicated than they have to be, but when they do have to be that complicated to get the full benefit, then so be it. Once this is commercially available, I'll happily deal with the learning curve for the benefits I think it would bring.

    Keyboard for Those on the Move [nytimes.com]

  • For those interested in something that fills this function, leverages your existing typing skills, and does not require chording check out the half keyboard [halfkeyboard.com]. The disadvantage I can see is that it isn't truly one-handed as you need to strap it to your other arm, and as a result it's also not "stealth". The advantage is you can buy it right now. I do not own one of these or endorse the product in any way, but I had a link that actually seemed to be on topic for once. :)
  • a good point of this 'keyboard' is that th hand can be held in th thumb up position which is our more natural tool using hand posture and i would imagine places much less pressure on th carpal tunnel

    and off on a small tangent i would like to see a 'keyboard' which uses two hands with th fingers lightly wired up and tapping against each other - probably also with chording combinations

    palms would be pressed together and held straight out while 'typing' or alternatively with th fingers pointing straight upward and th hands held in front of th chest - a lovely image of us communicating with our computers in a natural attitude of prayer
