Computer Mouse - Which One Is Right For You?

By Jesse Miller
The computer mouse is an accessory to the personal computer that has become an essential part of it's operation. Computer mouses is an instruments used to control your courser and function selection. There are many devices available in a variety of forms such as foot mouse, standard computer mouse, mouse keypad, light pen, joystick, touchpad, and trackball. The mouse cames in many designs, the device can be left hand only, right hand only or both left and right hand.

The ball-mouse replaced the external wheels with a single ball that could rotate in any direction. The ball mouse utilizes two rollers rolling against two sides of the ball. The mouse sends these signals to the computer system. Some by means of connecting wires and some are wireless. Mouse movements should be made using the elbow as the pivot point, not the wrist.

To select items or choose commands on the screen, the user presses one of the mouse's buttons, making the mouse click. The mouse gives directions to the computer where to move to the cursor on the monitor or screen, with one to three buttons (depending on design) allow the user to say yes by clicking the buttons. The press of a button closes the switch with a click and the computer has received a command. The driver tells the computer how to interpret the mouse's data stream including speed, direction, and clicked commands.

It's been almost half a century since the first computer mouse was put out of a Stanford lab in the '60s. Choices for a computer mouse has increased since then. The computer mouse has come a long way since then. The designs are many, Examples: wireless, small fats ones to fit kid hands,ones with three buttons, ones with a scroll in the center. Light pen design, short,long,thin, I could go on with all that they have in todays market. So when deciding which one to buy,take your time and get the one that is right for you.
