touchscreen and you


Change is the only constant. Talking of the IT sector, we all know how the market is flooded with touchscreen phones. The mass has shifted from numpad and qwerty phones to touchscreen phones in the last couple of years. Touch screen cell phones have revolutionized the communication world due to easier and quick screen navigation.
First for the general masses I would like to tell how the resistive and the capacitive  touch works. The resistive touch screen is made up of a  normal glass that is covered with a conductive and obviously resistive metallic layer. These two layers are held apart by spacers. An electrical current runs in the layer while the touch screen is operational. When a user touches the screen the change in the electrical field is noted and at that point, also the co-ordinates of the point are also recorded. Once the coordinates are known, a special driver translates the touch into the machine language i.e. the language your phone can understand.
The capacitive touch screen is better and has a unique method to find the coordinates of the touch. In this the panel stores some charge just like a capacitor and whenever the user touches it, some part of the charge is transferred to him. Then the change in charge on the glass panel is measured from all the corners.
Touch screens in general are very beneficial. First and foremost it saves me space. No extra keypad is required. And with phones its “SLEEK IS BETTER”. They have easier hand eye coordination than the mice, keyboard or keypads. I can go from 1 corner of the screen to other in no time. I just have to move my thumb. Plus there is no sensitivity issue. I don’t have to set the sensitivity of the mouse. It’s all in the speed of my thumb.

Touch screen these days is not only restricted to mobile phones. It has also revolutionized the industry. It’s simply not possible to use a desk or lappy everywhere. And computers are needed in every kind of work environment to perform various functions. Tablets are the perfect solution to this. they are compact and do not require any peripherals to operate them. Plus they have the potential to be more comfortable for the user. Pinch to zoom, drag and drop feature, haptical feedback etc acts as icing on the cake.
I feel that the touchscreens have changed the people communicated and worked and in coming years with advancement in touch technology, it has got to change things further.
