Handwriting Recognition on DS 112

Posted by CmdrTaco from the one-step-closer-to-pda dept.
JamesO writes "Zi Corporation has announced a licensing agreement with Nintendo that will allow developers to make use of handwriting recognition. PDAs have been offering handwriting recognition for some time and with the DS's touch screen it seemed inevitable that the console would eventually gain handwriting recognition technology. An agreement between Zi Corporation and Nintendo means that DS developers will be able to utilise Zi Decuma handwriting recognition technology when creating software for the handheld."

      You can code in Python for Windows CE 3.0+ (2.11+ maybe?), and specifically Pocket PC 2000, 2002, Windows Mobile 2003, 2003 SE and presumably 2005. There is a subset of Python, called Pippy, available for Palm OS. The WinCE port is pretty much a full port of Python; Pippy is very much stripped down. There are also the Zaurus Linux PDAs, which can run Python, though it's not as useful for writing full-on apps as it is on Pocket PC, at least within the Qtopia GUI last time I checked.

      Perl too on PocketPC/WinCE; there's even Perl/Tk support. Works pretty well.

    • You can write in Python for any machine in which the python embedding interface can be compiled, which includes the DS. Moreover, there are roundabout ways of getting C from a python script, though god forbid you ask #python how to do it (they'll give you a bunch of non-answers, then tell you you're being hostile and ban you.)

      If you really want to, you could use jython to compile through gcj to the DS directly.

    This certainly makes the DS more interesting to me (not that I'd use it as a PDA or anything). But if you can jot notes into the thing, and have it OCR'd for you, it would make it a lot handier than it is right now. Can anyone comment intelligently on how the DS CPU would handle such a thing?
    • Great Simpsons reference. That always makes my day.
    • Handwriting recognition != OCR, since there are no optics involved.

      • essentially they represent the same program. Most OCR programs can analyze any image for text, whether you scanned them, got them from a camera, or drew them with you mouse in mspaint. It's essentially the same problem. When you write on the screen, it creates an image, and analyzes the image to see if it can recognize anything as text. Most OCR programs only do typed text well. Recognizing hand writing is much too hard to do reliably.
        • Not necessarily. More advanced handwriting recognition algorithms can derive not only from a completed glyph, but also from the series of strokes you use in the process of drawing it.

          Try writing out the numeral 5, and then the letter S. Notice that even though the end results may look largely similar, the velocity and direction of your pen as you drew them were considerably different.
        • While both involve analyzing glyphs, one involves extracting a glyph from an interpolated image (a scanned document or simmilar), while the other has the benefit of having direct digital input.

          The prior is a different problem to solve. The hardest problem with OCR is reliably differentiating between a letter and a non-letter pixel on the page. Once you have the pixels that are just the letter, it is usually simple to figure out what letter it is. This is the idea behind Captchas, to make it as hard as possi

      The NDS main CPU is pretty slow- 66 MHz. I've used Decuma on Palm OS on a 200 MHz ARM (Sony Clie NX70v), and used Decuma fine, albeit a bit slowly, with the Clie underclocked at 100 MHz to save power. Decuma is decent HWR; it is in between the character-based stuff like Graffiti and the proper and good word-sentence based real HWR of the Newton or PocketPC's Transcriber or Calligrapher. It makes you write in a box- but you write a full word, it recognizes it letter by letter, and then you have to press a button to actually accept/write the text. Or make corrections, overwriting maybe 'e' for the misrecognized 'o'; then you press that button. On Palm OS, Decuma is about the best you're going to get if you want real HWR, but it isn't too horrible.
      • The NDS main CPU is pretty slow- 66 MHz.

        Still - that's three times the clock speed and several ARM revisions better than the Apple Newton. Plus the DS has a secondary processor that might be usable.

        Assuming there's been a modest improvement in HWR algorithmic efficiency over the past 10 years, I would imagine that the DS could do an admirable job.
        • Still - that's three times the clock speed and several ARM revisions better than the Apple Newton. Plus the DS has a secondary processor that might be usable.

          Several ARM revisions, yes; 3x clock speed, don't think so. IIRC the Newton ran somewhere around 160Mhz. Which I remember being very impressive at the time. :)

          • The (Newton) Message Pad 2x00 processor was a 162MHz StrongARM 110 but the older ones were only 20MHz ARM6. Incidentally, the MP120(2.0) and the MP130 ran the newer OS (same as the 2x00) that was very capable of decent handwriting recognition unlike the original lineup. Having extensively used both a MP120(2.0) and a MP2100 I can attest to this. The 2100's only advantage was speed.

            The DS has a 66MHz ARM9 and a 33MHz ARM7. Logically, unless the ARM7 is needed for some specific DS tasks you could have it
        • Indeed- though the Newton HWR didn't get really usable until the 162 MHz Newton 2x00s. The Newton 130 was pretty good too, and it had a slower (33 MHz?) CPU. It was about quality software more than CPU speed. A 1 GHz CPU wouldn't have made the earliest Newton OMP or 100 or 110 do HWR more than half-decently; the software just was written for to make it work real well.
      • The NDS main CPU is pretty slow- 66 MHz.

        Not that slow. The Palm III had a 16Mhz cpu. At the very least the NDS should be able to handle Grafiti :)
        • No, but like I said, Decume is more complicated than Graffiti. But also like I said, I've used it on an ARM clocked at 100 MHz, so I expect the DS to be usable.
      • This is pretty silly.
        • For one, handwriting recognition works fine on 386es.
        • For two, Palm has a fair amount of operating overhead.
        • For three, there are two CPUs, not one.
        • For four, the major limiting factor in handwriting recognition quality is algorithm quality, not CPU speed.
        • For five, there's no significant overhead to simply recording the sketching position; it would be trivially easy to recognize previous writing while working on storing the next set.

    Nintendo will now be marketing this to very young kids, once games come out that can teach kids how to write. Of course, this will depend on how good the handwriting recognition will be. This could be really good news for the future of penmanship, or really bad.
    • Actualy, if you think about it. The worse the recognician software is, the better for the kids. You could use the best algorythms for the beginners, and start using faster, easier to trick, but not stupid, recognician software for the advanced. This would really help if there was a learn to speak/write Mandarin or Japanese. I've already got a DS, and I'd pay quite a bit for a better method of learning Japanese than out of a book, and I don't really have two extra hours a day to go to any classes.
    • This could be really good news for the future of penmanship, or really bad.


      Would that really be so awful. My penmanship was never good to begin with but I find that I so rarely sit down and write with a pen that the skill has badly deteriorated. More so with cursive then printing. I'm not sure that it is a skill we badly need any more in modern society.

    There's already a Japanese-English dictionary for the DS, but it's so so at best. A good handwriting system for the machine would be an incredible boon - often times I'm presented with a kanji I simply don't know the reading for (and I can't input it into my electronic dictionary's QWERTY interface). I do know enough kanji to be able to copy many down by writing them, so being able to write say a compund and having the DS spit out a list of possible readings and defintions would be amazing and would help me learn Japanese in the real world (here in Japan anyway) more easily as I could begin decoding stuff in the world witout need of my onerous New Nelson Kanji dictionary.

    I've really been disappointed by the tiny progress in using a stylus for input. A decade and a half ago, "pen computing" was "the next big thing". Microsoft even marketed a "Word for Windows for Workgroups for Pen Computing" edition (presumably with a "Spellcheck for Word for..."). The Palm Pilot actually delivered on the Apple Newton's promise to use our pen skills to deal with little mobile devices. But now even Palm devices, like Treos, usually disregard the pen. I think it's not so much the lack of writing recognition (which is more than adequate, though it does have problems), as the lack of any unique pen advantages to compensate for having to use a separate pen rather than an integrated keyboard.

    Pens offered an opportunity to use an expressive, intuitive gestural interface. Even mouse gestures have run circles around pen gestures. I'd like to use a pen to indicate multiple selections, associations, layouts, flows, scales, shapes. I think an interface that used chinese symbols as commands on selected objects would have tremendous popularity, and maybe even work with a huge new global zeitgeist that could jump all kinds of boundaries represented by keyboards, especially QWERTY.

    We still have the opportinity to use pointers for a really expressive, simple interface "for the masses". I built a "light pen" for my Atari PC over 20 years ago. Even Treos still come with styluses, and now the DS will recognize handwriting. Most people use pens, probably even more than keyboards, especially worldwide. That input mode isn't going away, even if it's not being pushed. Even though OSes and apps still haven't delivered on their potential, there's still lots of pent-up (pun intended) demand to use them. I don't think the breakthru lies in dropping the pen in favor of a fingertip, though I'd like to see some working software that tested that avenue. I think that once we get a pen-centric UI paradigm that does things keyboards and mice cannot, we'll get pens that people won't put down.
