A computer mouse is a mechanical arm that converts the motion of the user in the control signal. With the development of computer technologies and engineering, the original mouse with a direct drive has undergone a lot of improvements, with the result that, today, the market of computer accessories is a huge selection of these accessories, ranging from laser and optical mice, touchpads finishing touch.

The principle of operation



The computer mouse became popular with the advent of the graphical user interface on a PC. Any mouse, regardless of its type (optical, laser, mechanical) perceives his own movement on the working plane, and transmits the received information to the computer. In turn, a special program installed on a personal computer, processes the data received from the mouse and plays them on the screen in the form of the action, corresponding to the direction and distance of its movement, such as moving a cursor on a computer screen in the direction in which the mouse was moved. This is the basic principle of operation.

In addition to cursor movement, the mouse is responsible for window management: opening and closing, as well as movement, acting as some sort of manipulator. In addition to the motion sensor, the mouse is equipped with one or more buttons and other details of the control (ring, scroll, joysticks, etc.). These buttons associate the action with the current position of the cursor on the computer screen.

Computer technology is constantly evolving and, in this regard, there is a huge range of mice, in which to understand the strength is not every experienced user, not to mention beginners.

Difference optical mouse laser



The greatest demand at the current market of computer mice are optical and laser mice, so it is good to know what distinguishes them from each other, not to be mistaken with a choice.

The main difference between computer mice apart is a type of sensor that is used for motion analysis. The working principle of optical mouse based on the luminous diode that radiates light in the visible range, and the sensor presents a small video camera, which makes about one thousand images per second. Received the camera data is processed by the CPU and then transferred to the computer monitor. The working principle of laser mouse is arranged similarly, with one significant difference: instead of the camera with diode uses a semiconductor laser that detects movement.

Another difference between these types of computer mice apart is their resolution. Optical mouse has a resolution of 1200 dpi and laser - 2000 dpi. For the operation and control of the mouse without delays and difficulties enough 800dpi, but the higher the resolution, the faster and more accurately the mouse responds to movement.

Another criterion for comparing optical and laser mouse is the speed. To hold the cursor across the screen, the mouse to be shifted by 2-3 cm, and the optical by as much as 5.

The following comparative criterion is the surface on which it is possible to mouse movement without delay or difficulty. Here laser mouse has a considerable advantage because it can move on any surfaces such as glass, fabric or wood. Optical mouse will also work on these surfaces, but significant challenges and numerous jumps.

And finally, the last difference laser mouse, the optical is the price on them. The laser mouse compared to optical, is slightly more expensive, but consumes much less energy. For wired mice is a special positive role will not play, but for wireless laser mice that work on batteries, there is considerable savings in consumption of energy from the battery.

Thus, comparison of laser and optical mice has shown that the first have a large number of advantages with respect to the second. Laser mice are not picky in the choice of the working surface, have higher resolution and less power consumption, making them some of the best computer accessories.
