[Peter Alcibiades]

Has anyone got touch screen working with webconverger? If so how you did it?

I need to set a FAQ for this question. :)

Webconverger doesn't support touch screen at the moment for two reasons:

1. Integrating touch drivers are often a _huge_ PITA. *Since I don't
have the hardware*, I can't verify the integration. :(
If it was a simple question of just adding a debian package, then
fine. But often enough it looks like:
http://home.eeti.com.tw/web20/eGalaxTouchDriver/linuxDriver.htm
https://help.ubuntu.com/community/EloTouchScreen

2. Webconverger does not have a virtual keyboard. I have looked into
adding one, but didn't get very far:
http://webconverger.org/blog/entry/Virtual_touch_screen_keyboard_for_Kiosks/

If any members of the community have anything to add please do. I
think I will create a http://webconverger.org/faq shortly.

In the next year I will have more time to focus on Webconverger and I
will look into purchasing some touch screen hardware.

Many many thanks!

Just GPL'd my virtual keyboard extension. You might have more luck with this: https://github.com/MarZab/FxKeyboard 

I have access to touchscreens ranging from IR, SAW, capacitive, to resistive from multiple firms. While most (newer) work OOTB, there are some that do need calibration.

Let's get this working :)

That's interesting Marko, thanks for you initiative here!

I've quickly built a DEBUG ISO with your extension enabled.
https://github.com/Webconverger/Debian-Live-config/tree/touchkeyboard
http://custom.webconverger.com/FxKeyboard.iso
md5 c5db9fe4b82cdf8d64d16da3db4a4b45

I also created http://webconverger.org/addons/ so I don't spend a
Sunday morning trying to remember how to install an extension. :}

Be good to build a list of hardware which "just work" (OOTB). :) Since
you're a github user, perhaps you can curate a page on
https://github.com/Webconverger/Debian-Live-config/wiki ?

I did play around with a http://www.zaagtech.com/ device in
hackerspace.sg and tbh I was dissapointed to put it mildly.

Noticed one bug already with your extension, doesn't seem to pop up
the keyboard 1.) input type=url on http://webconverger.com/

Can I suggest you re-license under the MIT license? It's a lot simpler
to work with.

I need update http://webconverger.org/blog/entry/Virtual_touch_screen_keyboard_for_Kiosks/
now. There is a suck less project that I might want to integrate into
Webconverger http://hg.suckless.org/svkbd/ instead of an addon. Would
have to write some code/overlay to make it hide/show. Lets work out
what's the best solution here. :)

Thanks again, need to focus on Webconverger 12 now.

I have not been able to come up with a good multi-touch solution, although some hardware I have does support it.

As for the list, I usually start searching here : http://lii-enac.fr/en/architecture/linux-input/multitouch-devices.html

For the ones that are not calibrated but supported, xinput_calibartion could be run while installing webc.

Noticed one bug already with your extension, doesn't seem to pop up

Fixed and committed, thanks.

Hi Marko Z,

Is it possible to port the firefox virtual keyboard extension to the
chromium extension ? Thanks.

Just to keep this conversation public:

As I said, a Chrome extension with this kind of functionality is AFAIK not possible. 

But chrome might be getting a native one soon:

In the mean time, maybe this will work for you:

Marko,

Do you have any recommendations for screens in the 32-42" range that work well OOTB?
