What type of computer mouse is

There are many kinds of mouse, the current commonly used mouse according to the principle of positioning divided into optical mouse, laser mouse, Blu-ray mouse and Blue mouse, perhaps most users do not understand the difference between them, only a few gamers have heard of these mouse types. Today we say the difference between the optical mouse, the laser mouse, the Blu-ray mouse and the Blue mouse, and the pros and cons.

Ordinary Optical Mouse

Positioning principle: The red side irradiation, the prism front capture image changes.

Advantages and disadvantages: low cost, enough to deal with daily use, reflective surface requirements are higher, so the purchase or use to be equipped with a suitable mouse pad (darker, not monochrome, not mirror more ideal), the disadvantage is relatively low resolution.

Resolution typical value: 1000DPI, normal range 800-2500dpi.

Photoelectric Mouse is a kind of hardware device which is used to detect the displacement of mouse by infrared ray or laser, convert the displacement signal into electric pulse signal, and then control the movement of the cursor arrow on the screen by program processing and transformation. The photoelectric sensor of the photoelectric mouse replaces the traditional rolling ball. This type of sensor needs to be used in conjunction with a specially designed pad with a striped or dotted pattern.

　Laser mouse

Positioning principle: Laser side irradiation, Prism side receive

Advantages and disadvantages: high cost, although the laser resolution of the mouse is quite high, on the reflection surface requirements low, that is, the requirements of the laser mouse pad is very low, but it is not legendary omnipotent, or with a suitable mouse pad for good. Laser Mouse has a high resolution, in fact, the price is not outrageous, mainly because this thing can be cottage, and the real cost of the mouse is spent on the wireless transceiver and mold, the shortcomings of the temporary discovery.

Resolution typical value: 5000DPI, also has less than 2000 resolution of low-end products

Laser mouse is actually a photoelectric mouse, but is a laser instead of the ordinary led light. The advantage is that it can be done through more surfaces, because the laser is coherent Light (coherent light), almost a single wavelength, even after a long distance transmission can still maintain its strengths click here to add picture description and waveform, while LED light is incoherent Light (incoherent light).

　　Blu-ray Mouse

Positioning principle: Blu-ray side irradiation, Prism front capture image changes.

Advantages and disadvantages: Low cost, daily use, Blu-ray mouse looks more eye-catching, in fact, personal sense led Blue to the eyes are not friendly, but not red more engaging some, the blue mouse on the reflective surface of the adaptability than the traditional red seems better, but not obvious. Disadvantage resolution is low.
