It would seem that a computer mouse is not itselfan important component of the whole computer in general, but no, without it, work for a PC turns into a very difficult, not fun-filled occupation. World brands A4Tech, Logitech, Defender are constantly fighting with each other for creating the best computer mouse in the world. That is why for the moment different kinds of computer mice constantly undergo changes for the better. If you constantly monitor all the novelties on the market of computer mice, and at the same time buy, at least one of the latest models, you can simply remain without money.
Surely many of you remember the first mouse,which recognized movements and coordinates thanks to the rubber bulb inside. All the old is always replaced by a new one, which is why nowadays it is less and less often remembered about mechanical manipulators. Optical mouse came to replace the mechanical, incorporating all of its best qualities. However, within a few years, a laser mouse, the latest development of various companies producing input devices, already knocked on the door.
The main choice: a laser mouse or optical?
While the guys from A4Tech have not yet come up with a newthe best principle of recognizing the coordinates of the mouse, before each user of the computer, laptop or netbook is the choice: a laser mouse or optical. That is why it is necessary to understand the advantages and disadvantages of the laser and optical mouse, in order to subsequently not have any difficulty in using one of the presented options.
Undoubtedly, a computer mouse, in addition to the fact thatleads the cursor on the screen, has two important features - accuracy and speed. These words will be confirmed by any professional gamer. In the race for precision, the mechanical manipulator has no chance of dealing with new input devices. Therefore, whether it is a laser mouse or optical, they are far gone in the race for accuracy from a mechanical mouse.
The very principle of the operation of both types of micethe same: the sensor takes a photo of the surface, and the chip inside the mouse analyzes this photo and determines the coordinates. When optical, as well as laser mouse, works, the surface from below the manipulator is highlighted. This is done for a better and accurate picture, which will make a special reading element, that's only in the optical mouse the LEDs work, while in the laser directly the laser. By the way, the laser better illuminates the surface being read, therefore the image quality of the image is much clearer than that of the LED. It turns out that the laser mouse is more precise than the optical one, because the laser is several times more accurate than the LED and does not distort the read image. This is the so-called small difference between a laser mouse and an optical mouse.
Тем не менее, кроме точности в хорошем manipulator is very important resolution and speed. Resolution is measured in units that are called dpi (in Russian - in dots per inch). Again, the laser mouse has a resolution of up to two thousand, while the optical mouse can boast of only one thousand two hundred points per inch. In truth, the most suitable and convenient extension for a pleasing mouse operation is eight hundred dots per inch, but computer manufacturers of computer manipulators simply use these indicators as a small marketing move. If you want, the resolution of the mouse can be adjusted in the control panel, and then you personally feel all the pros and cons of the high resolution of the manipulator.
Оптические мыши выпускаются в двух интерфейсах PS / 2 and USB, while laser only with USB interface. USB technology is more narrow-profile, and the data transfer speed can be less than PS / 2. Therefore, the cursor will move around the screen not so smoothly.
Now that you have become more familiar with theinput devices, try to determine whether the laser mouse or optical is the best for you, and be sure to try both.
