Our mouse senses our motion and our clicks and sends them to the computer so that it can respond appropriately. It is amazing how simple and effective a mouse is, and it is also amazing how long it took Mice to become a part of everyday life. Given that people naturally point at things -- usually before they speak -- it is surprising that it took so long for a good pointing device to develop. Although originally conceived in the 1960s, it took quite some time for mice to become mainstream. In the beginning there was no need to point because computers used crude interfaces like teletype machines or punch cards for data entry. The early text terminals did nothing more than emulate a teletype (using the screen to replace paper), so it was many years (well into the 1960s and early 1970s) before arrow keys were found on most terminals. Full screen editors were the first things to take real advantage of the cursor keys, and they offered humansthe first crude way to point. In this paper on“ WORKING OF OPTICAL MOUSE “ I’ll take the cover off of this important part of the human-machine interfaces and see exactly what makes it tick! INTRODUCTION Optical Technology uses an optical sensor to track movement, rather than the standard ball andmoving parts. Optical Technology provides increased control and precision and works on mostsurfaces. This superior technology translates into precise cursor movement and unmatchedresponsiveness.

Full screen editors were the first things to take real advantage of the cursor keys, and they offeredhumans the first crude way to point. Light pens were used on a variety of machines, as a pointing device for many years, and graphicstablets, joysticks and various other devices were also popular in the 1970s. None of these reallytook off as the pointing device of choice, however, when the mouse hit the scene, it was an immediate success. There is something about it that is completely natural. Compared to agraphics tablet, mice are extremely inexpensive and they take up very little desk space. In the PCworld, mice took longer to gain ground, mainly because of a lack of support in the Operating system. Once Windows 3.1 made Graphical User Interfaces (GUIs) a standard, the mouse becamethe PC-human interface of choice very quickly. Mice first broke onto the public stage with the introduction of the Apple Macintosh in 1984, andsince then they have helped to completely redefine the way we use computers. Every day of ourcomputing life, we reach out for our mouse whenever we want to move our cursor or activate something. Our mouse senses our motion and our clicks and sends them to the computer so it canrespond appropriately.

Open up a mouse and inside it we will find two wheels, each one similar to the first drawing. The wheel is usually made of black plastic with rectangular slots punched in it. I have shown only 6 slots at 60° spacing but they are a lot closer and many more. Shining through the slots are two LEDs (light Emitting Diodes) shown by the black dots. Each LED shines on to a light sensitive transistor. The two emitters are spaced so that, when one transistor can 'see' its LED through the centre of its window, the other LED is looking at an edge and is therefore switching on or off. In my illustration the LEDs are spaced at 105° (60° x 1.75). The output voltage from the transistor is processed to switch rapidly from high to low as the LED's light is transmitted or occluded so that the voltage is low when the transistor is lit and high when it is in darkness. In the diagram LED A is fully illuminated and LED B is switching. Note that LED B may be switching from light to dark or from dark to light - this depends on the rotation direction.
