Touchscreens or Human Machine Interface (HMI)

4.      Infrared Touchscreen Technology
In the Infrared Touchscreen Technology, an array of X- and Y- axes are fitted with pairs of IR Leds and photo detectors. The photo detectors detect any change in the pattern of light emitted by the Leds whenever the user touches the monitor/screen.

The potential novice touchscreen technology has many advantages over the conventional QWERTY keyboard and monitor. It is very flexible as opposed to its physical counterparts since the digital displays can be configured anytime at will of the user as per the functionalities. Touchscreen allows users to customize the interface for example alteration of language and size. By adjusting the size of the keyboard, user can utilize the spare area for display and other uses. With the decreasing size of computers and tablets these days, touchscreen is an added advantage. Multiple functions has to be performed on a small screen, touchscreen allows switching to a function at user’s will. For example, virtual keyboard which is an application of touchscreen is displayed on the screen only when the user allows it to be.
 
However, there is also the other side of the coin where there some functionality which cannot be performed using a regular touchscreen like cut-and-paste, right click menu options, drop-down menus.
