Using Touch Screen Technology
There are 3 components to a touch screen, well main ones anyway and they are; a touch sensors, a controller and the driver. The touch screen just needs a display and computer to work. The first component, the touch screen sensor is simply a glass plate that has a touch responsive surface. It is positioned over the display screen, usually an LCD or OLED screen so that the touch area of the plate covers the viewable area of the video screen. There are a lot of different touch sensor technologies in the market today, but each is able to know where your fingers are touching the screen.
The second component, the controller, is a small circuit board that connects the touch sensor and the PC. This circuit board simply takes the data it gets from the touch screen sensor and makes it into information the PC is able to process. The controller is usually located on the back of the monitor, and then has an extra cord to your PC, usually a USB cord.
The third component, or the software driver, is software that the PC system uses to allow the computer and touch screen to work in harmony. It simply lets the touch screen be used in the same way that a computer mouse is used, and this makes sure that you can use any program or software that only use mice to work with touch screens, something that makes touch screens a more viable alternative to mice.
What's the point of the touch screen if it doesn't have any uses? Here are some common and unique uses for a touch screen:
The first being use in public information displays such as trade show displays, tourism displays and other displays that are going to be used by a number of people who don't have much computer experience. It's a lot easier compared to other methods of input devices and it makes your information a lot more accessible by allowing someone to simply touch the display screen, no mouse screen coordination required.
The second one, probably the most common use for a touch screen is the retail and restaurant systems. It's incredibly useful to have a touch screen in your store or restaurant, as it's easier to train your employees to use the touch screen over a mouse or other device and work can get done a lot faster. You also don't have to have a mouse that while small, does require a large bit of counter space to get work done. They can be used in order entry stations, cash registers, seating, reservation systems and more.
The third use, probably the second most common use for a touch screen lies in our mobile devices and tablet technology. Texting has hit touch screens now, and it's very common to see people tapping their screens with a stylus or their fingers. For touch screens phones, you save a lot of space for a texting keyboard, which is a huge advantage when phones and mobile devices can use all the screen space they can get.
The main advantage of touch screen technology is how much simpler it is than other input devices, and if you can get rid of a keyboard and mouse combination, your workstation is going to be a lot less crowded and a lot easier to use.
