MOUSE ABCs
• A mouse is a hardware device which allows the user to control a cursor to manipulate data without complicated commands. The mouse or mice was invented by Douglas Englebart in 1963, who at the time was working at the StanfordResearch Institute, which was a think tank sponsored by Stanford University. The Mouse was originally referred to as an X-Y Position Indicator for a Display System. Xerox later applied the mouse to its revolutionary Alto computer system in 1973. However, because of Alto's unfortunate success, it was first widely used in the Apple Lisa computer. Today, the mouse is now found on every Apple and PCcomputer and used with various different GUIs.

MOUSE TECHNOLOGIES
– Mechanical Mice - Mechanical Mice requires that the mouse be set on a flat surface. The distance and the speed of the rollers inside the mouse determines how far the mouse cursor moves on the screen depending on the software configuration. – Optical Mice - Optical Mice require a special mouse pad which has a grid pattern. Asensor inside the mouse determines the movement by reading the grid as the mouse passes over it while emitting a light from an LED or sometimes a laser. This type of mouse is much more accurate than the ordinary optical mechanical mouse which relies on the traction between the mouse ball and the rollers. One drawback to an optical mouse is they can have problems in bright lights. – New Optical Miceno longer have the disadvantages of earlier mice and are capable of being utilized on any surface. In comparison to the traditional Optical-Mechanical mouse, the Optical is a much better solution for a computer mouse.

– Optical-Mechanical - The optical-mechanical hybrid consists of a ball which rolls a wheel inside the mouse. This wheel contains a circle of holes and or notches to read the LEDby a sensor as it spins around when the mouse is moved. This mouse is much more accurate than the mechanical mouse. This mouse is now the most commonly used mouse with PC and Macintosh computers. See How a mouse works for an illustration and a more in-depth explanation of how this mouse works.

HOW A MOUSE WORKS
• The optical mechanical mouse's operation is fairly simple. As you can see inthe below illustration, the mouse movement is tracked by four parts. As the mouse is moved, the ball rolls in the direction of the movement which, in turn, moves the roller (X or Y axis). As the roller begins to rotate, so does the chopper / gear. The gear has small notches within it or around the edges of it; as it rotates, light shines through the openings which is then detected by the two lightsensors which then sends the computer a signal of that movement. The offset of the light received by the two light sensors determines the direction of each axis.

HOW A MOUSE WORKS

Within the mouse you will find a total of two rollers and choppers / gears. Each roller represents a X or Y axis which is the Horizontal or Vertical movement of the mouse cursor.

MOUSE DISASSEMBLY
• Theillustration below shows the disassembly of a standard mouse. As shown you can see that the internal components of a mouse. We have illustrated the general location of four main components within the mouse.

• First, you will notice the two Choppers and or Gears; these two represent the axis of where the cursor is located. The chopper furthest to the represents the X axis, which is the verticalaxis. The other chopper, which is only partially shown, represents the Y axis, which is the horizontal axis. • Second, you notice the mouse ball. The mouse ball is the main part within the mouse which allows the user to move the mouse which moves the appropriate axis which then moves the mouse cursor on the screen. Without the mouse ball the mouse would be useless. • Third, you notice the four pin...
