Proximity, which makes sense because mentally you're similar or physically so you're attracted to each other. They say opposites attract which is sometimes true but often times it's similar qualities that bring people together.
The integer would be 100 above 0.

There are many different touchscreens. Resistive, Capacitive, Infrared, Surface Acoustic Wave, Near field imaging, and Light pens. However, I am going to talk about Resistive, since that is the most popular in touchscreen technologies. They basically have a flexible upper layer of conducting polyester plastic bonded to a rigid lower layer of conducting glass and separated by an insulating membrane. When you touch the screen, you force the polyester to touch the glass and it will complete a circuit in the touchscreen. A chip inside will figure out where you touched the phone and send out an output.
