A touch screen monitor is an input and output device normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus and/or one or more fingers(support several user to touch at the same time).
Touch screen monitors also called the all-in-one pc, as it includes the whiteboard, computer, TV, projector function.
Some touch screen monitor use ordinary or specially coated gloves to work while others may only work using a special stylus/pen. The user can use the touch screen to react to what is displayed and to control how it is displayed; for example, zooming to increase the text size.
In this situation, our products can be touched by finger directly, no need to use a pen or other tools.
If you buy a big size interactive touch screen, you can control it like your mobile phone(freestyle), which will be more convenient than the traditional untouchable classroom or meeting room screen monitor.
