Infrared:
There are two methods of using Infrared touch screen technology:
A.) Thermal stimulated changes of the surface resistance.
B.) An arrangement of vertical and horizontal IR sensors that identify the disruption of a modulated light beam in the vicinity of the surface in the screen.
IR touch screens possess the most resilient surfaces and are widely used in numerous military applications that need a touch panel display.
Strain Gauge: In this method the screen is spring mounted on the four corners and strain gauges are employed to find out deflection whenever the screen is touched. They are used to safeguard touch screen railway ticket machines from destruction.
Optical Imaging: Optical imaging refers to a touch screen technological process where two or more image sensors are located around the edges of the screen. Infrared backlights are positioned in the camera field of view on the other sides of the screen. A touch turns up as a shadow and every pair of cameras can be easily triangulated to locate the touch. Optical Imaging technology is gradually catching strides as it is extremely scaleable, useful and cost effective.
Dispersive Signal Technology:
Dispersive Signal Technology uses sensors to identify the mechanical energy in the glass that takes place due to a touch. Intricate algorithms deduce the information and give us the exact position of the touch. The technology provides exceptional optical clarity and remains unaffected by dust and other outside elements.
Acoustic Pulse Recognition: Acoustic Pulse Recognition is a technological process that uses over two piezoelectric transducers positioned at similar places of the screen to convert the mechanical energy of a touch into an electronic signal. Thereafter, electronic signal is transformed into an audio file, and then judged against pre-existing audio profile for every position on the screen. This method is highly precise and doesn’t require a conductive object to activate it.
