What Type of Touchscreen Notebook Computers Are Available

Touchscreen notebook computers are not like traditional computers in that they do not have a keyboard and mouse with them. This type of computer is actually an evolution of the touch-screen computer, or better called the virtual keyboard, which came out with the IBM Model M. That model had one of the earliest designs of a touchscreen computer and it is still the most popular one on the market today. Since the touchscreen is so different from the normal computer keyboard, it is understandable that it would be an evolutionary change from the existing keyboards.

An Overview

The reason that it is different is because it uses a sensor to sense where the user is in the computer. There are typically three buttons on the screen which are arranged to access all the applications on the screen. To press these buttons a sensor will detect the motion of your finger. This sensor is usually referred to as capacitive since it senses the positive or negative charge that is placed between the button and your finger. When you press a key it will give a corresponding electronic signal to tell the screen what type of action should take place.

Because of this unique sensing technology it is possible for touchscreen notebook computers to have higher levels of sensitivity than normal keyboards. This means that a much larger percentage of the computer screen will be covered with something that your finger actually touches. In fact the whole surface of the screen may not be touched, but only the portion that you are actually touching will be. Obviously, you can just imagine how many times you will touch the screen without even realizing it. And, this also makes for a very responsive computer.

Some Drawbacks

This also has a disadvantage though. Each time you touch the screen it updates the display. This means that your view of what is on the screen will be constantly changing. In fact, some screens can update more rapidly than others. You may have a lot of flashy software on the screen and a slow computer that just scrolls text.

This is why some people prefer a full physical keyboard for their computer. They are able to type without actually touching the computer. However, there is always the risk of the screen freezing every time you touch it. When you are done typing the computer will turn off. This means you have to reboot it. Also, you need to be careful of the sensitivity of the keys since if you are careless and press the wrong key the computer could crash.

Capacitive Touchscreen

One of the most recent types of touch screen computers is called capacitive. The screen is charged by your finger. The actual liquid crystal displays (LCDs) are placed underneath the screen. In this case the liquid crystals have been charged electrically. As you touch the screen they respond to your touch. This means there are no liquid fluids involved and the response is not slowed by electricity.

So, which one should you get? The answer really depends on what you are looking for. If you are just looking for a computer for doing simple web browsing and sending email then you might want to go with a touch type. If you are looking for a computer for playing games and watching high definition videos then you might want to go with a finger PC. But, even with those options you still have more to choose from such as optical mice and even devices like optical keyboards.

Conclusion

Even though touchscreen notebook computers are wonderful inventions they do have their drawbacks. One thing that irritates many users is the fact that if you accidentally touch the screen it will automatically turn off the computer. However, the developers of these devices have had some type of solution for that problem. Other than that these devices are amazing and we all should try to use one.
