Touchscreen

I learned about this when I was working on my Tinder Robot. Revising while I review ECE222.

Touchscreens are implemented today through Capacitive Sensing:

• Since people are electrical conductors, if an insulator like glass is covered with a transparent conductor, touching distorts the electrostatic field of the screen, which results in a change in capacitance.
• This technology can allow multiple touches simultaneously, which recognizes gestures that can lead to attractive user interfaces.
