How Touch Screen Technology Helps [aboutcomputer99.blogspot.com]

Have you ever wondered about touch screen computer monitors? I mean, how do they know where you are touching in the first place?

Today we find touch screen POS (points of sale) everywhere.

• Checkout stands in stores • Gas pump service stations • Fast food restaurant check stands

And that is just to name a few places where touch screen LCD monitors can be found today. I'm sure you can think of others.

No matter if it is a Samsung or Acer screen the mystery of how such devices recognize your finger, pen or stylus remains. Gone are the less intriguing days of dragging a mouse across the screen to complete your selection. Today's users are presented with a more interactive and interesting technical connection than ever before.

Currently, the three most common ways that these LCD monitors recognize your touch include:

1. Resistive 2. Capacitive 3. Acoustic

Though infrared technologies within are steadily f inding their place within the industry.

How does the resistive approach work?

First, a conductive and resistive metallic sheer covers the glass panel so that both layers are separated by electrically charged spacers during operations. Both layers are forced to connect when the screen is touched thereby sending the proper message to the computers network of communications.

Comparatively, capacitive technology actually maintains an electrical charge on top of the glass panel. A touch screen LCD monitor using capacitive processes releases some of the charge into the user's finger. The lack of charge at that spot in the system is interpreted by the device as an entry which is then processed accordingly.

Finally, the surface acoustic wave system introduces transducers at the sides of the glass plate. Reflectors then use electrical signals to interpret what is being communicated by the user's actions.

Which touch screen computer best buy is right for you?

This largely depends on the purposes you have for such technology within your own projects. Whatever you decide, the bottom line is that today's technology within touch screen computer monitors is steadily moving forward.

Answer by Fajner1
If it only has touch screen (a tablet), it's not very good. But if it has both a touchscreen and a standard keyboard+trackpad setup, then it's good.
