Embedded in phones, office equipment, speakers, digital photo frames, TV control buttons, remote controls, GPS systems, automotive keyless entry, and medical monitoring equipment, touchscreens are everywhere. As a component, they have reached into every industry, every product type, every size, and every application at every price point. Touchscreens are everywhere.
