History of Touch Screen Technology

1960sHistorians consider the first touch screen to be a capacitive touch screen invented by E.A. Johnson at the Royal Radar Establishment, Malvern, UK, around 1965 - 1967. The inventor published a full description of touch screen technology for air traffic control in an article published in 1968. 1970sIn 1971, a "touch sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor called the "Elograph" was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology. The Elograph was selected by Industrial Research as one of the 100 Most Significant New Technical Products of the Year 1973.

In 1974, the first true touch screen incorporating a transparent surface came on the scene developed by Sam Hurst and Elographics. In 1977, Elographics developed and patented a resistive touch screen technology, the most popular touch screen technology in use today.

In 1977, Siemens Corporation financed an effort by Elographics to produce the first curved glass touch sensor interface, which became the first device to have the name "touch screen" attached to it. On February 24, 1994, the company officially changed its name from Elographics to Elo TouchSystems.

1980sIn 1983, the computer manufacturing company, Hewlett-Packard introduced the HP-150, a home computer with touch screen technology. The HP-150 had a built in grid of infrared beams across the front of the monitor which detected finger movements. However, the infrared sensors would collect dust and require frequent cleanings. 1990sThe nineties introduced smart phones and handhelds with touch screen technology. In 1993, Apple released the Newton PDA, equipped with handwriting recognition; and IBM released the first smart phone called Simon, which featured a calendar, note pad, and fax function, and a touch screen interface that allowed users to dial phone numbers. In 1996, Palm entered the PDA market and advanced touch screen technology with its Pilot series. 2000sIn 2002, Microsoft introduced the Windows XP Tablet edition and started its entry into touch technology. However, you could say that the increase in the popularity of touch screen smart phones defined the 2000s. In 2007, Apple introduced the king of smart phones, the iPhone, with nothing but touch screen technology which was the basis of the iPad. But as you can see it started a lot earlier than that

The very first complete TouchScreen Tablet can be defined when in 1994 the European Union initiated the 'OMI-NewsPAD' project (EP9252), requiring a consumer devise be developed for the receipt and consumption of electronically delivered news / newspapers and associated multi-media.

The NewsPad name and project goals were borrowed from and inspired by Arthur C. Clarke's 1965 screenplay and Stanley Kubrick's 1968 film: 2001: A Space Odyssey. Acorn Computers developed and delivered an ARM based touchscreen tablet computer for this program, branded the NewsPad. The device was supplied for the duration of the Barcelona based trial, which ended in 1997.

In 1996, The Webbook Company announced the first internet-based tablet, then referred to as a Web Surfboard, that would run Java and utilize a RISC processor.

In 1999 Intel announced a Strong ARM based touch screen tablet computer under the name WebPAD, the tablet was later re-branded as the "Intel Web Tablet"

One early implementation of a Linux tablet was the ProGear by FrontPath. The ProGear used a Transmeta chip and a resistive digitizer. The ProGear initially came with a version of Slackware Linux, but could later be bought with Windows 98.
