Touchscreen computer interfaces: Electronics

Abstract

This chapter will review the history and role of touch screen electronics as the interface to touch technology. Touch screens are user-friendly input devices that are quickly becoming a human interface standard. Common examples of touch screen applications include cell phones, GPS units, public kiosks, and industrial or medical input devices. Touch adds to the value proposition of a wide variety of products by enhancing functionality and ease of use. Touch screen systems are typically made up of three key elements: the touch screen sensor, the electronics, and the display. This chapter will explore how touch electronics profoundly impacts design, functionality, and customer experience in touch systems.
