  • How is the CharaChorder keyboard even possible?

    From Themi@21:1/5 to All on Fri Dec 17 00:44:20 2021
    Recently I stumbled across a video of someone typing very fast on a
    standard query keyboard using the "charachorder lite" keyboard. Now,
    despite only typing at about 60wpm I am obsessed with finding ways of
    typing faster so this really caught my eye. https://www.charachorder.com/

    This keyboard uses "chording", meaning you can press more then one key
    at a time in order to type out a whole word. The steno machines used for
    court reporting and live captioning also use chording, I've never tried
    to learn how to type steno though since it seems extremely difficult and
    steno machines are crazy expensive.

    Anyways, the charachorder claims to having a more simple chording system
    that is easier to pick up. You're supposed to be able to click on every
    key making up a word at once and it will type the whole word out, that
    way you don't need to type every letter in order individually. Naturally
    my first thought was "I want to make a program that does that for
    myself", and then my second thought was "wait what about anagrams??".

    Imagine you want to type the word "this", so you press keys "this" at
    the same time. How can the keyboard possibly know if you intended to
    type "this" or if you intended to type "shit"? The only answer I can
    think of is context, maybe there's some sort of predictive ai that's
    able to tell in context if you likely meant this or shit. At the same
    time though, how many words can you make with the letters "t h i s"?

    Well I downloaded a word dictionary and wrote a short script that
    figured it out. I came up with the following list of words: ['hist',
    'hists', 'hits', 'isth', 'shist', 'shists', 'shit', 'shits', 'sisith',
    'sith', 'stith', 'this', 'thitsi', 'tshi', 'tsitsith']

    I tried a whole bunch of other common words and nearly every time there
    where 5+ fairly common words that fit the same chording.

    I can't imagine a predictive ai could be very accurate at guessing
    between what of these words you intended to type! Maybe I'm
    underestimating ai, or maybe I am missing something here. There's got to
    be some sort of big caveat here.

    Unfortunately I can't take a peek into the charachorder's software since
    the keyboard has a microprocessor that does all the work built into it.
    I may try to learn how to make a predictive ai in order to test this out
    since I've just got to know soon.

    What do you guys think? Am I missing something obvious here?

    At a quick glance, looks like the T9 for mobile phones or e.g. search suggestions when you start typing in the browser, and similar: it also means it has to keep some kind record of past entries, i.e. of anything typed including logins, passwords and
    bank account numbers, so 'd be more curious to know how they handle that.

    That said, there certainly is room for creative approaches to computer keyboards: it is well known that qwerty and similar are the opposite of ergonomic/effective...

    I'm definitely not advertising haha, I'm questioning if this product
    even works. I found it on kickstarter which makes it super questionable
    in my opinion since I've seen so many projects from there fall on their
    face in the past.

    hmm that is an interesting point, it probably does keep a history of
    past entries. This probably isn't something that warrants using ai then
    now that I think about it, I could certainly try and use a simple
    "frequently used" algorithm that maybe takes into account the context of
    the previous few words like suggestions on mobile phone keyboards do. I
    think I may try that out.

    Maybe using standard chording software where you define what keys
    correlate to what words more of the move here since you won't end up
    typing words you didn't expect to like it seems like you may using a
    system like CharaChorder is.

    You clearly demonstrated one proof that typing all the keys
    of a word simultaneously doesn't work. However, typing two
    keys at once would allow them to represent 676 words. Too
    much to have to remember. There are 44 phonemes in English.
    These could be remembered and used to represent words which
    an intelligent program to transform back to standard spelling.

    I find the very mission objectionable: "to elevate average human text transmission speed (40 wpm) above and beyond average human text comprehension speed (250 wpm)". Why do we even need that if not along the way of the extinction of thinking? More
    concretely, isn't at that point rather speech recognition and beyond the way to go?

    That's often good enough already. Yet don't discount ML as it's doing great in the realm of next word prediction up to automatic writing, with very good results over relatively limited computing resources.

    Maybe using standard chording software where you define what keys
    correlate to what words more of the move here since you won't end up
    typing words you didn't expect to like it seems like you may using a
    system like CharaChorder is.

    By the videos, it rather seems it's exactly like changing a word in T9. Rather, good luck learning yet another "bag of tricks". And when you borrow your friend's PC, back to square one? But I guess a subcutaneous chip with Bluetooth interface
    connecting to an onboard universal device might solve even that...
