Touchscreens Options in Windows 7

In today’s world there are revolutionary changes in computer world and the revolution comes with the introduction of touch screen technology. In short touch-screen changed the concept of hard-press to soft-press which gives a lot of ease to the end user.

With the introduction of touch screen you can tap your finger in button of viewing window of computer with less effort .The touch key board in tablet PC input panel is very easy to use and in one touch you can manage and access all program and files .The common task will be more easier by the new gestures .Now you can easily enter into the text on a touch screen without using a physical keyboard, by updated touch keyboard in tablet PC input panel. Touch screen is an electronic visual display which can detect the presence of your touch. It is very sensitive and it helps users to interact with computers with one soft touch .There are three basic systems to recognize a person’s touch:


In resistive system a normal glass panel is covered with a conductive and a metallic layer of resistive. By spacers the two layers are separated from each other and the whole set up covered by a scratch resistant layer on the top so when users touches the screen the two layers make contact with each other with that exact spot and the change in electrical field is recorded and this coordination is calculated by the computer.
In surface acoustic system two sensors (one transmitter and one receiver) are placed with the horizontal and vertical axis of the monitor’s glass plate. If the wave has been disturbed, the receiving sensor will be able to detect and accordingly locate it .It do not leave any metallic layers on the screen and produce an absolute perfect picture quality. This makes the surface acoustic wave system best for displaying graphics.
In capacitive system a glass panel is placed with a layer of stored electrical charges and some of the charge is transferred to the users when he or she touches the monitor so charge of the capacitive layer decreases in the monitor where circuits located in each corner of the monitor measures the decrease of the charge.

This type of technology is obviously very beneficial as in this technology you don’t have to input any extra device such as mouse or a key board. the user only need his or her finger to manipulate the chosen device so the possibilities with touch screen monitors are endless .Touch screen computers are commonly used in medical field , stores ,industrial applications , cell phones , ATM machines etc. Touch screen technology used in I Phone has provided user a new leap in using various applications in a single touch.
The touch screen computer’s best feature is the ease of selection without use of mouse to scroll and select .A touch screen computer users can click on music files or photos with a swipe of their finger on the computer screen. So at last we can say that if computer makes mans life easy touch screen made it even easier and effortless.

Smart dust technology could still take a while

Kris Pister a researcher from the 1990’s had a dream that no one of his time thought could turn into reality. His dream was simple, scatter sensor like devices just like dust over the earth. These sensors were thought of not being anything bigger than the size of a grain of rice. He called these no bigger than a grain of rice particles “Smart Dust.

These particles would have the ability to monitor everything right from wireless radios, sensing equipment wireless radios and a lot more. All this because of simple computing power, you would have information at your finger tips like information on cities, information on people and even their natural environment.

This revolutionary idea is no longer a dream, infact after all these years we now see it coming to reality. One mans vision is another man’s invention that’s what we would like to call it.

Pister who is now a computing professor and teaching at the University of California, Berkeley seems to be very thrilled about his idea coming to life. Although it was 14 years ago that he had dreamt if this technological phase, it is finally being devised.

Hewlett-Packard had made an announcement a few days ago, that it was working on a new project that they call “Central Nervous System for the Earth.” The company has planned it big and has mentioned that it would look at computing trillion sensors that would be scattered in every part of the planet.

The devices that HP would create will not only check our ecosystems regularly but would also help in knowing beforehand if there is any possibility of natural disasters occurring. The plan is huge, and its use is seamless, the possibilities are endless as well. HP says that the particles will also help in reducing the accident rates worldwide.

The move will begin around two years later; this was mentioned by the senior research Pete Hartwell at the HP lab in Palo Alto. The company has already teamed up with Royal Dutch Shell so that it can go ahead and install about 1 million of those minute monitoring particles. This move will help in oil exploration simply by checking the movement and vibrations in rocks. The sensors will work across an area that spans 6sq miles.

The sensors that HP has already manufactured are around the size of a VHS tape, and that is after all the sensors are put into a box so as to protect it. These sensors although the size of a matchbox are 1,000 times powerful than what you have in your Smartphone’s!

However the idea of Smart Dust may still take a while to make its appearance. You have to give technology time to come up with ways and plans so that sensors are no bigger than a few millimetres. Researches at Berkeley are working endlessly at this possibility of creating smart dust that can be sprinkled casually around the surface of the earth. It might take us a while before we come to that phase of technology.
