The resulting resistive technology touch screen was first shown on the World's Fair at Knoxville in 1982. [20] 1982 MULTI-TOUCH CAMERA - Multi-touch technology began in 1982, when the University of Toronto's Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass.
Resistive touchscreen technology works well with almost any stylus-like object, and can also be operated with gloved fingers and bare fingers alike. In some circumstances, this is more desirable than a capacitive touchscreen, which needs a capacitive pointer, such as a bare finger (though some capacitive sensors can detect gloves and some gloves can work with all capacitive screens).
In computing, multi-touch is technology which enables a touchpad or touchscreen to recognize more than one [7] [8] or more than two [9] points of contact with the surface. Apple popularized the term "multi-touch" in 2007 with which it implemented additional functionality, such as pinch to zoom or to activate certain subroutines attached to predefined gestures.
A touch user interface (TUI) is a computer-pointing technology based upon the sense of touch ().Whereas a graphical user interface (GUI) relies upon the sense of sight, a 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.
Tactile technology is the integration of multi-sensory triggers within physical objects, allowing "real world" interactions with technology. It is similar to haptic technology , as both focus on touch interactions with technology, but whereas haptic is simulated touch, tactile is physical touch.
Many electronic visual displays are informally referred to as touch screens. Starting in the early 2000s, flat-panel displays began to dominate the industry, as cathode-ray tubes (CRT) were phased out, especially for computer applications.
