Re: Input Method Development
this uim has an embedded scheme interpreter... I don't like that too much for an embedded device... hmm, I have no idea: is it big, slow? It's apparently used on Linux Zaurus. We could adapt the openmoko soft keyboard to interface with uim, and if the API is well designed, the IM module could be changed... I'm not sure adapting to a soft keyboard would be required. It may seize key presses emit appropriate utf-8 key values. Try installing it on your desktop trying it with a few soft keyboards. could someone update me on the differences between these kr input methods described in the doc? * Byeoru * Hangul (2-beol) * Hangul (3-beol) * Hangul (Romaja) I have no clue. Were you intending this for the mailing list? I'm assuming so, but only saw this addressed to myself. Yeah, I know the patents problem with T9. But what about this one? What one? uim is open-source, so there aren't patent issues (if that's your question). ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Input Method Development
(keeping [EMAIL PROTECTED] and communitylist in the loop) Hehe, This is totally understandable. :) We will explain to you the best as we can. If you want to make a korean keyboard with a key for each letter then you'll need a keyboard with... (sit down before next line) ... 11,172 letters, ie from \uAC00 to \uD7A3 + 24 single letters or jamos ! see here: http://en.wikipedia.org/wiki/Hangul http://en.wikipedia.org/wiki/Hangul#Syllabic_blocks Of course there is a special method. The korean keyboard layout is a single qwerty, each key with a jamo (single letters). The 11172 syllabes are made of combined jamos , and a state machine can be used to track which keys have been pressed, and how they have to be combined. See my previous messages for an explanation. However when I searched the Internet for my use, I did not find a lot of information on this, so I did the research. About you soft keyboard, I think the problem can be solved with the use of plugins, ie a method that takes keystrokes and outputs characters. For European scripts, the routine will be quite trivial, but for other scripts, this is needed. With such plugins, we can also imagine support for other complex scripts such as chinese or indian or whatever. An input method will then be made of an XML file describing the layout, and a .so to hold the key-character translation algorithm. Sebastien 2008/2/7, Jeremiah Flerchinger [EMAIL PROTECTED]: Please forgive me for not putting much thought into the problem before. I'm really only familiar with European languages none of this work is in my area of expertise. I have started some reading on IME and other input methods. I'll have to think about the issue and what extensions would eventually need to be made. Jeremiah Flerchinger wrote: The idea behind what I started is that you can make a soft keyboard with any number of rows keys. Each key could be assigned any arbitrary utf-8 value. If more symbols are needed a file can be created describing another keyboard layout with additional keys. Maybe it's impractical to have a key for each character place them all into different keyboard layouts. Any insight to the problem and how keyboards are typically used/configured in Korea would be appreciated. Even though I would be unable to do localization, I could try to rethink the current design to further meet international needs. Sébastien Lorquet wrote: Hi, nicely done, this program is complementary with what I did! But a Korean IME engine will require additions to your program, it's not only a matter of xml layout. Maybe a plugin system that receives key presses and emits characters. Basically it's a state machine that will read latin letters and output korean letters according to combinations. I have a small keypress stack and a ~60KB next states file. for example, you type b a and you get a ba syllabe as a single Unicode character. Not to mention we will need to add a korean font in the neo. I'm happy with this project. I'm OK to help, if needed.

Re: Input Method Development
Sorry for the imprecision, and thanks for the correction. I spoke too fast. The backtracking should be trivial to implement with my prototype. I'm cleaning it a little before giving it to you. I'm also concerned with copyright. Is there any patent problem with this input method as with T9 (for mobiles) ? What I made is reverse engineering. I plan to release it under GPLv3 to be protected from software patents, will this be useful? What do you think?

Being able to backtrack is quite necessary in this case. The exact behaviour of BS, DEL, and cursor keys is yet to be defined to make this a complete spec. What happens when i press BS e.g. 8 times? What, when i press LEFT DEL END BS? Obviously BS should edit last sylable, but can you edit completed sylables (needs back-translation unicode-keystrokes!), and how does cursor movement affect closing sylables? just my 2 cents j ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Input Method Development
for what I recall, backspace starts by removing *letters* from the last syllable, then entire syllabes. Moreover, hitting a directional key like LEFT RIGHT or any key that changes the caret position terminates composition of the current syllabe. In fact, when you type, the currently composed syllabe appears in blinking inverted video, and a SPACE or the end of possible composition (ie, no more letters can be combined into a valid syllabe) terminates the sequence. At this point, the real syllabe is displayed normally as a unicode character and composition starts again. I noticed that in some editors where this blinking character cannot appear (e.g. in a cmd.exe console), the current combination is displayed in the corner of the current window in a small frame. Writing a complete spec is a good idea ;) seb ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Input Method Development
Hi, I have absolutely no idea on how to develop IM methods on OpenMoko, but one day I tried to implement a hangul IME for Windows CE. It's based on the one from windows XP IME2002, ie type tpqktmxldkd to get 세바스티앙. The UI does not work yet, but the internal state machine is OK. It's written in C. I don't know if you worked on this part but maybe it can help...

Input Method Development
I just received my Neo1973, and since I require Korean input, I'd like to do it myself... I'd like to do something similar to the soft qwerty keyboard -- except that I'd use Korean letters instead of Latin ones. I've poked around the wiki, but I haven't found any good pointers on creating and adding input methods. Any pointers would be greatly appreciated.

Re: Input Method Development
I've done a little work on a soft querty keyboard written with GTK. It is reconfigurable, by use of an xml config file, and I was playing with support for UTF-8. I haven't had time in the last couple weeks to work on it because of my work school schedule. A slightly out of date version is available in a tar.gz http://projects.openmoko.org/projects/gtkeypad/ Feel free to look at it, create a Korean xml config file, and add to the source. I have slightly newer code on my computer that I need to post. I also have to get everything into the CVS after Alessandro lurlano told me how to correct an authentication issue.

Re: Input Method Development
I'll have a look, thanks for that. Including Korean into an xml file won't be easy as the Korean script is a little more complex to implement than the Latin one. Let's take Sébastien's example: tpqktmxldkd to get 세바스티앙. When you type tp ypu get 세 but when you add q [tpq] you get 셉, not 세ㅂ. Only if and when you type k [tpqk] does the letter ㅂ goes away from 셉 to form a syllable with k/ㅏ. Basycally you have the following: t -- ㅅ tp - 세 tpq - 셉 tpqk - 세바 tpqkt - 세밧 etc... And it can get trickier. Also, although a qwerty kbd might be a start [as the Korean keyboard is overlaid on top of qwerty anyway], I was also thinking of a smaller keyboard, àla mobile phone kbd -- some of the keyboards available on Korean phones are quite astute, and require fewer keys. Anyway, I'll have a look and see what can be done.

some more notes: - this is exactly the behaviour of IME2002 engine, at least what can be *observed* on a korean windows xp computer - as you can see, there is a state that should be displayed somewhere, and a output that is not generated regularly. - for the curious, I tested the algorithm on my girlfriend's name, whose syllabes are perfect for a last-vowel test :) Seb ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

(sorry for the multiple messages) I am also highly interested by a mobile phone-like korean typepad, but I've never seen one, and I don't know how it works.
