The key to this expertise is that a touch at any one position on the floor generates a sound wave within the substrate which then produces a unique combined signal as measured by three or extra tiny transducers attached to the sides of the touchscreen.

This discovery helped discovered what we as we speak consult with as resistive contact technology (because it responds purely to stress moderately than electrical conductivity, working with each a stylus and a finger).
1 Some touchscreens use abnormal or specially coated gloves to work while others may only work utilizing a particular stylus or pen.
