Offseting XY Touch Coordinates

Post by LuiZbim » 29 Jan 2014, 19:47

Hi, my current project demands me to stretch my display between two monitors (a touch one and a normal one).
However after doing so, the touch calibration becomes useless because it tries to cover both screens area (while I need it only on the touch screen). I couldn't find a good way to offset or customize my calibration in Windows' options...

So I'm hoping anyone can tell me if there's a way in Ventuz to offset or adjust the values the touch is receiving and "trick" the computer so it gets calibrated artificially. Thanks in advance!

Hi Luizbim

Not easy to do in Ventuz - if at all possible?

I came across these guys - http://touch-base.com/download.asp

You can even download a test driver limited to a 100 clicks to test your set up.

Allows you to have a touch monitor in a cluster and have correct coordinates.

Hello Peter, thanks for doing some research, I've already requested a driver, hope it helps.

I'm still learning a lot from Ventuz, maybe you can help me understand if a cluster of machines would let me interact with my presentation the same way as my current multi-screen display, and WITHOUT stretching the desktop.. as it is the main problem.

Thanks again :)

First, thanks Christian and Alex!

I haven't been able to test the TUIO toolbox yet, but I think a free driver/software like that is my best option as Alex says.
After trying many options, asking people and doing research, I became aware my request was REALLY specific.. that's because the hardware and displays we will use to show the presentation are even more specific :/

Alex, I have both Ventuz 3 and Ventuz 4 PLE licenses, but I did the project only in Ventuz 3, so I'll take a look at the Ventuz 4 new Render Settings.
However, I managed to calculate the touch offset by using some Clipping Nodes but it's still a tedious and incorrect way of solving it, if nothing works maybe I'll contact your sales guys Alex :D haha.

Thanks again!

Japp, if you are using TUIO, the ToolBox should be very helpful for your setup...
Cheers,
