Re: [lojban] Computer Friendly Handwriting

well using lined paper it should be pretty easy (middle vs. touching top or bottom)

also, assume top =100 bottom=0

the difference in hight can be more than half

eg.

0,1,1 would be 0-50-50

0,2,2 would be 0-100-100

but 011 could also be written 0-10-10

this would make the difference even greater adn easier to see (it woul dnot be confused with 000 because 000 would not have any corners)

if you mean for the computer reading..

then you are perhaps confusing this with glyph based OCR

the computer would never looks ta the "shape as a whole".. that is needed for glyph recognition(like latin alphabet) but that whole level of the software is not needed here

basically dont think of them like you would normal glyphs, you would never "compare shapes", just read "absolute hight values"

I'm not sure how you are supposed to tell the difference between letters of the same shape at different heights, like a and n, d and q. I'm otherwise quite a fan of all of your work

Of course I will.

Ill try to remember to send you a copy of the code when I get around to it :)

That sounds really cool! I hope you'll post on your facebook page when it's done.

as per "underestimating" OCR requirements.
as I pointed out this would be more like QR codes, it only has to "trace" the line and it has all the data. OCR needs an extra step where it compares likeness to known glyphs. a whole leve lis gone.

I plan to build some readng software as soon as I have time. I am planning on first doing it in PHP so it is easy for others to test and modify, but to do a reall "speed test" I will need to do it in C

As per Palm OS graffiti
That only works if it is draw into the system in real time. not if it is scanned in after the fact. it relies on knowing the stroke direction, something that is lost in scan of written text.

Rather the opposite; http://en.wikipedia.org/wiki/Graffiti_(Palm_OS)

My question is why the hell you would invent something as painfully
terrible on the human as Cscript when Graffiti is know to be
entirely workable in real time on what is in the modern day a
trivial processor.
