Can trackbar values be sent from another device?

I have made a traffic light detection algorithm with OpenCV and Python. My script has some trackbars which I need to adjust and see the output to set a desired stage.

My script runs on my Raspberry Pi, is there any way I can send the trackbar values from another device on the same network on the RPi? For example, maybe make a phone app (I use Windows Phone BTW) which sends the trackbar data to the script and shows the output on my phone screen.

sure:

>>> help(cv2.setTrackbarPos)
Help on built-in function setTrackbarPos:

setTrackbarPos(...)
    setTrackbarPos(trackbarname, winname, pos) -> None

so just send your values to your script (e.g, via sockets or bluetooth), and call cv2.setTrackbarPos() once you receive something

Call each value by a separate name and hence call the respective trackbar.. sweet! But how do I see the script's output on my screen?
