finally, with the kind help of the guys at microsoft.public.windows.tabletpc, i made chinese handwriting recognition work on my tabletpc :) it wasn’t difficult at all, i just needed to install a chinese keyboard service in addition to chinese tabletpc services. it’s not an intuitive solution though (as i don’t have a chinese keyboard and i didn’t want anything but chinese handwriting recognition). ms should have mentioned this in the documentation or better, redesigned the user interface to be more intuitive and hence more user-friendly.

how well does it perform? the recognition rate isn’t particularly good – given the fact that my “chinese handwriting” rather resembles “print characters written by hand” than “true” chinese handwriting (i.e. chinese written by a chinese). quite obviously, recognizing “true” chinese handwriting is more difficult than recognizing chinese print characters (even for humans). nevertheless it’s at least better than if i had to type pinyin (ymmv, particularly if you’re chinese).

now i’d wish there were an automatic transcription of simplified (and/or traditional) chinese to pinyin (which was easy to do with “windows for pen computing” according to fritz switzer)

I start to like my TabletPC :)

I just found two great applications for drawing sketches using a TabletPC:

Ambient ArtRage 1.0. Freeware. Nice effects, intuitive GUI. Sometimes somewhat slow in response (there’s a noticeable lag).
Alias Sketchbook Pro 1.0.3. A commercial tool (free trial) with a very intuitive GUI and a very realistic look and feel (nice work, guys! Kudos!). Excellent, like real, but with the advantages of digital imaging :) That’s how I imagined to use my TabletPC! As a bonus feature, Alias offers useful background templates for free download (among them some cool story board templates :). Have a look at the insightful Penny Arcade SketchBookPro tutorial! For artists (painters, designers, ..) the TabletPC concept is really a “must-have-a-look-at”!

Further, I’ve installed the enhanced Wacom TabletPC driver which enables pen pressure level support for legacy applications.

In other news, I’ve posted a couple of messages to microsoft.public.windows.tabletpc.developer
I hope this will help me make Chinese handwriting recognition work.

ok. i installed/enabled the eastern asian language pack on my tabletpc. for some (unknown) reason however, i couldn’t enable chinese handwriting recognition. i was only given a choice of “de” (german), “de_ch” (german for swiss) and “en” (u.s. english). bummer.

so i asked ben who first pointed me to a tabletpc mvp’s blog (which appeared having been abandoned as it only featured a single, out-dated entry), then to microsoft.public.windows.tabletpc. the thing i actually was looking for was some kind of synchronous real-time peer support the way it is common in oss communities (almost every oss project provides irc channels for its devs and users). as it turned out, there doesn’t seem to exist any such thing (a central real-time meeting point for devs and users, like irc.freenode.net) in the ms-sphere.

now here comes my free consulting for microsoft: get synchronous community communication up and running. i know there are efforts in this direction (e.g. www.codezone.ch or www.codezone.de) – but this is not enough. don’t implement community building from top-down. it’s too much services-like, with all the disadvantages i bet you can imagine. instead just provide infrastructure (think of irc.microsoft.com) for user groups to build a sustainable community from “bottom-up” themselves. and heck, if it’s a matter of money, divert some hundred million marketing dollars to initial grass-roots, bottom-up community building efforts. users will thank you (and stockholders as well).

in today’s chinese lesson i realized that the only reason for me to actually use the tabletpc’s handwriting recognition feature would be writing in chinese. why? because that’s the only application where the tabletpc’s handwriting recognition could eventually be faster than normal typing on a keyboard (to write chinese characters, you first need to type pinyin, i.e. the latin transcription, then choose the right chinese character from a drop-down menu or similar. usually, there are several choices as pinyin is ambiguous. this procedure takes quite a while for each chinese character). it would eventually also solve the problem (for westeners such as me) of finding the correct pinyin for a certain chinese character.

i wonder whether there are any such applications? some links i found so far:

Here are some short comments both on the Toshiba Portégé M200 (as a piece of hardware) and on the TabletPC concept in general (software etc.). Note that these comments reflect nothing but my very personal opinion.

HW:

– Overall performance is nice (Pentium M 1.6 GHz, 768 MB RAM, GeForce FX Go5200 32 MB).

– The Geforce is sufficiently fast for playing low-resolution games (I’d say up to 1024×768 pixels) with rather poor texturing. It’s clearly not sufficient for playing current games with excessive use of textures (remember it only has 32 MB of memory).

– The keyboard layout is very unusual and plain stupid, particularly for CS/IT professionals (e.g. []{} are not indicated and placed wrongly, <> are in the wrong places, home/end are placed in the upper right corner, barely usable, windows keys are in the upper right corner too – silly). Grossly negligent.

– The lower part of the notebook (the keyboard) is a bit thick for my taste (coming from a thin, nice Sony Vaio N505X). Typing is tedious and bad for the wrists. [update 20040617: Meanwhile, I’ve managed to get accustomed to it]

– The screen is disappointing. It’s a high-res screen with 1400×1050 pixels. That’s nice. It’s bright and I can even read it in sunny environments. That’s nice too. The bad thing is the very low contrast and the distortion which is probably caused by the special screen coating (makes the screen feel rough to improve the “paper feeling” when writing on the screen using the pen). The distortion drives me crazy and my eyes start burning after a very short time (this never happened with any other LCD screen I’ve used so far). I’ve tested it both with and without glasses. It’s always bad, but particularly harmful for people wearing glasses. Be warned! [update 20040617: Meanwhile, I’ve managed to get accustomed to it]

– The touchpad is a bit too small (and therefore inaccurate) for a 1400×1050 screen resolution

– The rest of the HW (as far as tested) meets my expectations (= is okay)

The thing I’m asking myself: Why is it so hard to build an ergonomically good convertible TabletPC or notebook device?

SW:

– Pen input recognition is pretty amazing from a programer’s perspective (that’s perhaps where all the “wows” come from) but clearly disappointing and insufficient from a real-world user’s view. It’s slow (if you decrease the delay the recognition rate drops rapidly). The input recognition rate is (for my hand-writing, which isn’t neither particularly nice nor ugly) correct in about 95% of the letters. This rate drops to about 30% when entering URLs, mixed character/number words, special characters and in mixed, multi-language environments (which might be seldom in the US, but very common for us Europeans and particularly Swiss people). It’s totally unusable for entering passwords and such. Some of the problems are probably due to missing learning/adjustment capabilities (MS obviously chose a dictionary based approach instead). [20040617: this is no longer true for XP SP2 RC2 (Lonestar) where handwriting recognition and overall ergonomics are much better]

– Pen input requires too many clicks and is a painful experience overall. Lonestar allegedly will address some of the issues, but as far as I can judge from the video cap, it still won’t do a decent job (pen input is still too complicated and inconvenient for being an alternative to keyboard input). After using Windows XP TabletPC Edition for a while I have to conclude, that this is basically just a regular Windows XP with an “Inking” add-on. It’s not really designed for tablet use and pen input (even in Lonestar, you can’t just start writing inside a text field – that’s how it should be done actually). Clicking on regular Windows icons is as difficult as choosing the right menu entry. Both are too difficult and not very handy. I wonder how Apple or Palm would approach such a task.

– Windows XP TabletPC Edition has a nasty bug that prevented me from calibrating speech recognition (it displayed little squares instead of a readable font)

– When entering user credentials at the login screen, people can observe (thanks to the virtual keyboard displayed on the screen) when shift is being pressed. That’s a potential security weakness.

– For me, the use of the pen can be reduced to painting and designing (therefore, it’s pretty handy, much more convenient than using a regular mouse)

[20040617: entry appropriately updated. see also the follow-up article on XP SP2 RC2]

when upgrading suse 9.0 to suse 9.1 yesterday early morning, my workstation’s setup got screwed. it wasn’t suse’s fault (one of the cdroms was bad) but nevertheless i had to cancel a party due this unexpected incident (it was my only working desktop linux setup and therefore mission critical for my diploma thesis). as i couldn’t solve the problems, i decided to switch to debian instead (currently “testing”, will upgrade to “unstable” asap). so far, a rather positive experience. debian boots faster, debian shuts down faster and even kde 3.2 runs faster on it (despite of lacking pre-linking!). for installing it, i’ve used the new debian sarge netinst beta4 installer. had still some flaws (e.g. screen resolution was not set correctly, dns settings had to be fixed manually, keyboard settings weren’t correct), but overall, it’s surprisingly stable already.

nb. i still think that suse is doing a great job as a distro (very convenient to use and well integrated). but now as i switched to debian for my desktop, i’ll probably install debian on my tabletpc too, thus standardizing on debian and windows xp for workstations and gentoo for servers.

good news: finally, my toshiba portégé m200 has arrived at the ssd-shop :) i’ll pick it up tomorrow. i’ll use the opportunity to also order a logitech mx510 optical mouse, a lite-on 431 sx slim dvd +/- burner (external, usb 2.0) and a replacement battery for an old vaio.

[update 20040512: ssd’s supplier didn’t have the mx510 on stock, so i decided to buy it elsewhere (i need it now, not in 2 months ;).. unfortunately it’s sold out already in the only shop in zurich where i’ve seen it a couple of days ago. no surprise for me (hey, it’s the ultimate gamer mouse :), but obviously for logitech and partners. i’ve made a reservation so i’ll get it asap.
further i decided to order the lite-on 431 sx slim dvd +/- burner (external, usb 2.0) at fuerst-informatik.ch, who offered it for a really good price with (as i was told) quick delivery. further, as i’ve surprisingly noticed that my portégé m200 features 802.11b/g (not only b), i will also order a new wlan access point: linksys wrt54gs which can be equipped with embedded linux: Linux on the WRT54G, LinksysWrt54g – SeattleWireless:)]
