A resistive touch screen is one in which a thin layer of metal of acts of resistance as the primary sensory level. The coating is resistant to the touch and is transmitted as an electrical impulse. In contrast, capacitive touch screen uses capacitive tendency of the human body to cause interference in capacitive touch sense level. Alternatively, the surface wave touch screen, uses ultrasound waves.
These waves pass over the touch panel. Some waves are absorbed when the user touches the screen.
