How a computer mouse works.

A computer mouse - one of the essential components of any modern computer system. This "rat" has long been a part of not only the desktop but also the laptop, albeit in a slightly modified form.

Computer mouse look.

Computer mouse looks like a computer mouse, everyone knows. In some ways, it really looks like a well-known pest, albeit with some reservations. It is believed that future generations of users of this association is not clear. Although, wireless, just because modern computer mouse performs faster, loses the "tail".

Role Of Computer Mouse.

The principle of operation of this device is extremely surprisingly simple: when this special software is transferred to a computer, where the cursor movement on the screen pointer is transferred to the level of relative coordinates. What's interesting, it can be not only the usual arrows of the operating system, but also the role in a computer game. The apparent simplicity behind it hides the work of engineers, electronics engineers and programmers. Depending on the structural features of the computer mouse can be different word movement. Let us remember what is really the difference between these seemingly identical devices.

Old Computer Mouse.

Original computer mouse first models appeared 50 years ago, were mechanical. Inside the tool is a massive metal ball coated with a layer of rubber. Downstairs, they came in contact with the outer surface, and the other two - with rollers. They may be four, but only two were executed. When you move the mouse ball rolling lists passing through them - switch, and then the electrical signals are sent to the computer was changed in the same sequence. Two rollers is enough to get the coordinate point on the plane. Disadvantages of this solution include the need for periodic cleaning ball (precise dusting of air hair) and replacement of worn components from the dirt process.

Soon they were replaced by optical mechanical solutions. From the outside, everything remains unchanged, but the switch is removed, replaced by a more robust solution - the optocoupler. The name "terrible" refers to the opto pair, collectively optical sensors for LED and concealed very harmless. Each roller was combined with a hole wheel arranged between the sensor and the diode. When rotating the beam that was recorded by the obstruction stream sensor and transmitted to the computer. Frequency shift "window / wall" is all-knowing, it was not possible to determine the speed and direction of movement.

The most expensive computer mouse.

The most expensive computer mouse There were in 1999, the original computer mouse, called optical, which managed to completely abandon the mechanical method of recording movement. The LED illuminates the surface under the mouse, and captures images of a primitive camera with some frequency. The processor unit handles them based on the end result is the speed and direction of migration. We can only transfer data to the driver program.

Soon they were replaced by laser modification. Increasing the accuracy of the processor focus, "difficulties" surfaces on which the sensor does not work is almost gone, has become more productive. The main difference from other types of optical LEDs, which is available, and not infrared. By the way, the most expensive computer mouse - it's a laser. However, due to its high cost (over 24 thousand) is mainly inlaid gemstone, not technical features
