What is Touchscreen?
[[File:JazzMutant Lemur.jpg|thumb|249x178px|JazzMutant Lemur]] A '''touchscreen''' is a [[computer]] [[Computer monitor|screen]] that can be used by touching it with a [[finger]] or a [[stylus]] pen, instead of using a [[computer mouse|mouse]] or [[remote control]]. It can be described as a [[touchpad]] with a screen built-in to it. Today, all kinds of [[computer hardware|devices]], both big and small, use touchscreens. However, [[tablet computer]]s and [[smartphone]]s have made them popular and are the most widely known and used products that use touchscreens. ==History== In 1965, E.A Johnson of [[England]]’s [[Royal Radar Establishment]], invented<ref>{{Cite web|title=What's the History of Touch Screen Technology?|url=https://www.thoughtco.com/who-invented-touch-screen-technology-1992535|access-date=2024-02-18|website=ThoughtCo|language=en}}</ref> the first touchscreen that was used in the U.K for [[air traffic control]] up until around 1995. The first resistive touch screen was invented by [[G. Samuel Hurst]] in 1975, and produced in 1982. Back in 1970, Hurst and nine friends discovered that a touchscreen on a computer monitor made for an excellent method of interaction. Pressure on the cover sheet allowed [[voltage]] to flow between the X [[wire]]s and the Y wires, which could be measured to indicate [[Coordinate system|coordinates]]. This discovery helped found what we today refer to as resistive touch technology (because it responds purely to pressure rather than [[electrical]] [[conductivity]], working with both a stylus and a finger). Much later in 2005, three friends from France created a multi-touch screen capable of tracking any numbers of fingers. By 2005, their company named JazzMutant released the [[Lemur]], a [[music]] controller with a multi-touch screen [[User Interface|interface]]. This new technology helped influenced the [[TactaPad]] also made in 2005. Two years later, in January 2007, the [[iPhone]] was released, which was controlled entirely by a multi-touch screen.<ref>{{cite web|url=htt
