What is the Computer Interface?




The computer Interface is like a “tool” and “Concept” that refers to a point of interaction between components. It is applicable at the level of both hardware and software.

  1.         Physical Interfaces.
  2.        Text-user Interfaces.
  3.        Graphical-user Interfaces.
  4.         Web Interfaces.
  5.        Touch Interfaces.
  6.        Natural user Interfaces.  

What is the Touch user Interface?


touch user interface (TUI) is a computer-pointing technology based upon the sense of touch (haptics). Whereas a graphical user interface(GUI) relies upon the sense of sight, the TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with visual impairments, an added level of interaction based upon tactile or Braille input.



History of Touch Interfaces.

In 1954 Hugh Le Caine demonstrating the prototype of the ''Touch Sensitive Organ'' Le Caine began work on this instrument between 1952 and 1954 at his home studio. He brought the prototype organ to the National Research Council lab in 1954 and considerable development took place over the next year.

In 1971, a "touch sensor" was developed by Doctor Sam Hurst. 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 and The Elograph was selected by Industrial Research as one of the 100 Most Significant New Technical Products of the Year 1973.


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 Touch Systems.
