View Full Version : Touch Screen Programming

04-02-2004, 01:19 PM
I was wondering if anyone knew any information on touch screen programming.

The project I am trying to complete is to take a 37" Plasma screen, install a touch screen frame over it. I need a custom program that will display all the computers on the network. There will be buttons that are graphically displayed and when you touch one of them, a separate window would come up displaying certain information.

Would anyone happen to have any information on freelance programmers, or programming companies that could provide this type of work.
Money is not an issue.

I can't say this for sure, but I did have a prospective project a year ago, that involved touch-screen programming. From what I researched back then my impression was that the touch-screen drivers would generate messages that where the same as regular mouse button messages. So basically if an application could work with a mouse, it should work with a touch-screen, provided the hardware and drivers where installed correctly. Unfortunately the project fell through before reaching the implementation phase because of lack of funding, so I never got to confirm my beliefs.
The point is, that as far as I know, programming for a touch-screen device is no different than programming a normal Windows application.

If that is the case, do you, or anyone that reads the boards know a good place to look for talented freelance workers, or talented programming companys so I can find out how much money people would charge for a custom program.

Google "freelance contract development" and ye shall find...
(Beware of bids that seem too cheap, though. There's usually a reason for that).

I dont know the answer to your question, but what you are doing seems extremly cool :D

This is completely off topic:

Where can I buy touchscreen frames, how much do they cost, and where can I find more info?

BTW, I dont know for sure about your answer, but If I had to say, I would agree with shmoove's theory that you need the correct drivers and thats it.

I'm a freelance windows programmer!! ... If you haven't already found someone to do it I would be happy to give my services after a little more information so I can get some sort of a timeframe to see if I'm available... I believe shmoove is correct in saying that it should be the same as a mouse.

Yes. It is the same.

I've made some stuff before that was intended to be used on a 'normal' machine with a mouse, but that was also ran on PC's with touchscreens. I can't recal making any adjustments at all.

It were real touchscreens, but i've also seem cheaper alternatifs (at college) where they placed a 'filter' over a traditional screen. The screen displayed, and the filter recorded the input.
I've also once seen a demo of a projectionscreen that could be used as a touchscreen (hand and laserpen) but i think noone realy saw the advantages of such system.

My company designs touch screens for Meusems, you can contact their sales office for info, I know that either they can do it in house, or send you to some freelancer who can. I don't have the info and I won't have time to run around and drag it out -- you can go on their website and send the sales guys a message:

Incidentally, I would think the technology would be the same building as a web page... you would just use that type of plasma screen to accept finger touches like a mouse click, but I'm not sure. I've designed them interactive flash work for that purpose, but only our in house marketing stuff.

Also, if you want some competition questioning, anyone who offers full service designs for museums will offer this service. Google has many:)

Is one vendor, they're really, really nice when you're making a presentation because you can use your hands as the mouse right on the board. I wish more of our conference rooms had them.
