Revolutionary device
Posted by Maik Beckenbauer | Filed under Hard
We all know what computers are. We love them more than any other machine in the world, and for some of us we could not even dare imagine how our lives could have been without them by our side. Truth be told computers have become regular household appliances in our homes holding as much weight as (if not more than) refrigerators and washing machines in order of the importance to the smooth running of our lives. The most revolutionary design creation that made the computer tick was none other than in my opinion the development of the computer mouse. It basically happens to be a graphical aiding pointing device that allows the user to operate most computing functions by simply point and clicking on items as they appear on a display screen. This enables one to operate the machine using purely hand to eye coordination making it one of the easiest and most basic computing skill sets to learn and master.
This revolutionary device has slowly developed over the years. The earlier computer mouse models had a track ball design incorporated into their working mechanism and would determine inputs in relation to the movement of the ball relaying a two dimensional input data to the system which through the system is relayed to the screen area. Later the first ever mechanical mouse was developed as an improved version of the track ball only that in this case the ball is rolled between the mouse and the surface. Later models use a laser sensor that emits light. These are longer lasting than the previous, models as they do not have parts that are susceptible to wear unlike the rubber track ball designs. Traditionally it was a two button device with each having their own separate functions but evolution has led to the incorporation of an extra wheel button whose function comes in handy while scrolling up and down through various windows without much of a fuss.
So next time you see a computer mouse next to your keyboard be sure to admire the architecture, design and thought that went into building this simple work of art
