Touch Screen GUI

Sounds like a pain to do it with dual monitors... might want to do a little research on that. So far this is just the screens ie not much underlying code yet.

What do you think of the over all look and feel?

Edit: I just tested it on the BP and it would work well on a 12" or larger monitor at 800 x 600 minimum size. Buttons are easy to touch, everything seems natural to me... but I'm a bit off from time to time.

I just looked up a smaller ELO touch screen and the 1515L seems like a good one and no power brick is needed. The native resolution on it is 1024 x 768 so I think I'll upgrade to that size and see how it lays out.

With a 1024 x 768 screen the buttons are at least 3/4" in any direction so plenty easy to hit once you get the screen calibrated. I was even using Axis on the touch screen... but not easy to hit the tabs.

I wrote a little script to edit /usr/lib/X11xorg.conf.d/69-evtouch.conf and after editing I'd reboot and see if I made it worse or better. I could not find a calibration program.

For another $100 you can get a 15" ELO touch screen... that one is cool as it only has one plug the USB one.

So far I have figured out how to color a label background but not a button. I've made some changes and tested the GUI on my touch screen. For now I have labels under the top row of buttons to indicate the state of the button. I'll try and get some more screen shots of what I have so far today.

Here is what I have so far...

The Manual Screen


The Auto Screen


The File Screen


If you can print them out and see what the machine operators think...
