What triggers touch screen?

This conductive material responds when contacted by another electrical conductor, like your bare finger. When you touch your screen, an electric circuit is completed at the point where your finger makes contact, changing the electrical charge at this location. Your device registers this information as a “touch event.”

Is there a way to simulate touch screen?

Conveniently for you (seeing that you are a programmer), a significantly better interface is using the Android Debug Bridge to simulate touch screen presses, swipes, back and home key presses. Basically your main goal is to get ADB functioning. There’s plenty of resources online so I won’t explain it here.
