Creating touchscreen buttons

Hey all!

Im doing a project for a touchscreen, in a text-based world!

I have limesurvey up and running- but since its a touchscreen kiosk, there won't be a keyboard available. So my thought was to run a script to display pressable icons - In this case, the images of the local radio stations.

The theory being- User presses a button on the screen, it registers as a click, and the script automagically takes this as standard input rather than a keyboard.

Anyone have any experience/direction? :mrgreen:

if it's in a browser (which presumably it is since you're here) focus on making the buttons easy to hit with your finger. BIG is the answer.

Most touch screen devices just register a touch as a mouse click, so there's not too much different.

Yes- the plan is to display it as localhost on Firefox ( Everything security conscience otherwise) When I skimmed the surface of touchscreen programming with qt4, I figured that a touch was considered the same as a mouse click.

My thinking was to have Limesurvey left justified, and have this ... box of choices .... to the right, set to always on top.
User clicks an icon corresponding to a radiostation (I.E. fly92), Limesurvey gets Fly92 in text and moves to the next question.

This is to be operated on 12" touchscreens, and we were thinking no more than 8 choices in the box. Worst-case scenario, theres a next tab in the box to cycle through choices ... but I'm certainly not at that point yet.
