Touch Screen

Technology With Touch Screens

Most people use touch screen tablets such as Apple Ipads or Blackberry tablets or Galaxy Samsung tablets etc. There are a number of different makes of tablets and very popular phones that majority of us will own or have maybe before. But most of us wouldn't know how the touch screen device actually works the background of them and how they actually came around.

Apple

Apple are one of the most famous and popular make of touch screen devices they produce Iphones, Ipads even Ipods. they also do computers and 'mac' (laptop). I would say they are popular because they are one of the best companies and they produce one of the best and most efficient touch screen devices and technology yet.

What they are and how they work

A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. Some touchscreens can also detect objects such as a stylus or ordinary or specially coated gloves. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size).Touchscreens are common in devices such as game consoles, all-in-one computers, tablet computers, and smartphones. They can also be attached to computers or, as terminals, to networks. They also play a prominent role in the design of digital appliances such as personal digital assistants (PDAs), satellite navigation devices, mobile phones, and video games.

The Market

The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are popular in the medical field and in heavy industry, as well as in kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display's content. There are also personal users such as children and parents or even sharing one as a whole family.

History

E.A. Johnson described his work on capacitive touch screens in a short article which is published in 1965 and then more fully—along with photographs and diagrams—in an article published in 1967. A description of the applicability of the touch technology for air traffic control was described in an article published in 1968. Bent Stumpe with the aid of Frank Beck, both engineers from CERN, developed a transparent touch screen in the early 1970s and it was manufactured by CERN and put to use in 1973. This touchscreen was based on Bent Stumpe's work at a television factory in the early 1960s. A resistive touch screen was developed by American inventor G. Samuel Hurst who received US patent #3,911,215 on Oct. 7, 1975. The first version was produced in 1982.In the early 1980s General Motors tasked its Delco Electronics division with a project aimed at replacing an automobile's non essential functions (i.e. other than throttle, transmission, braking and steering) from mechanical or electro-mechanical systems with solid state alternatives wherever possible. The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input. The EEC replaced the traditional mechanical stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicles cumulative and current operating status in real time. The ECC was standard equipment on the 1985-1989 Buick Riviera and later the 1988-89 Buick Reatta, but was unpopular with consumers partly due to technophobia on behalf of some traditional Buick customers, but mostly because of costly to repair technical problems suffered by the ECC's touchscreen which being the sole access method, would render climate control or stereo operation impossible.
