Issues with multitouch panel

Hi guys, how are you?

I have a little project, but I cannot deal with it properly. I have a small LED Screen of a resolution of 240x240 (1,5 m2 aprox), and I want to have the multitouch panel from widget designer. The thing is that since the resolution of the screen of WD is higher to the resolution of the LED Screen, nothing works properly... I thought that configuring the panel as the AirScan should work, but it doesn't... I supposed to use the node system, but I have no clue how to do it... I try use the input Multi-Touch Item and Multi-Touch Panel Point to try to convert the values, but... nothing.

Some help please? Thank you!

Hi,

The AirScan Tool menu offers you the possibility to change the "Resolution" of the input processing. Did you try that?

The other way includes the AirScan input node and using "Filter (Range) nodes to change the values from 0-WDscreenWidth to 0-LEDscreenWidth.

Best regards
Dennis

Hi, I've already try to change those values that you are telling me, including with the node system, but is not working at all. I mean, I already change the values to fit the screen to the resolution of WD, but this is not working on the multi touch panel.

What I have found helps is if you change the resolution of your WD screen to the closest aspect ratio of your output panel (as close to 1:1 as you can)

Then make a Multi-touch panel in WD and make it full screen;
Check Layer 1 so it shows up on that Multi-Touch panel, but don't activate any controls!

Now, put a test pattern (of the right aspect ratio) like "Geometry" on the LED screen;

Adjust the values in the Airscan tool until the center of the "X" in geometry matches with the "1" in the Multi touch panel (so the circle goes around it - adjust the sides and then adjust the X & Y offset so these all match up.

That is usually my work flow for odd size screens.
I have found that it doesn't really matter what the Airscan tool says as far as aspect ratio goes, just as long as it all fits.


Good Luck!
