The mouse by interface type can be divided into a serial mouse, PS / 2 mouse, line mouse, USB mouse(mostly photoelectric mouse).

Serial mouse is connected to the computer through serial port, there are two kinds of interface which is 25 and 9 needle interface; PS / 2 mouse through a six stitches mini DIN interface connected to the computer, it's very similar to the keyboard interface, pay attention to distinction when using; Bus mouse interface on the bus interface card; USB mouse through a USB interface, directly inserted in the computer's USB port.

The mouse according to the working principle and different internal structure can be divided into three types which are mechanical, optomechanical and optical.

Mechanical mouse

The mechanical mouse is mainly composed of ball, roller column and sensor of grating signal. When you drag the mouse, driven in ball, ball make drive roller rotation, the sensor of grating signal installed in the roller end which happen the photoelectric pulse sensor signal reflects the mouse change in the vertical and horizontal displacement in the direction, through processing and transforming of the computer program to control the movement of the cursor arrow on the screen.

Optomechanical mouse

Optomechanical mouse, as the name implies, is a combination of optical and mechanical mouse.(a type of mouse in which motion is translated into directional signals through a combination of optical means).On the basis of the mechanical mouse, it become non-contact correlation light path components instead of wearing the best contact brush and decode the round. When the ball rolling, X, Y direction of the roller rotating drive yards. Installed in the encoder, flanked by two groups of leds and light activated triode LED light beam from the exposure to the light activated triode, sometimes is blocked, from group and two-stage pulse sequence of the phase difference of 90°. The number of pulses represents the movement of a mouse, and the phase in the direction of the mouse movement. The adoption of non-contact parts and reduce the wear rate, thereby greatly improving the life and make the mouse mouse target precision is increased. The appearance of the mouse light machine and mechanical mouse makes no difference, do not open the mouse shell is very difficult to distinguish.

Optical mouse

Optical mouse is through the detection displacement of mouse, the displacement signal transform into electrical signal, again through the process of processing and conversion to control the movement of the arrow cursor on the screen. Optical mouse with photoelectric sensor instead of a ball. This kind of sensor need tailor-made, plate with stripes or spots.

Optical mouse

Optical mouse is a senior mouse by Microsoft company. It uses NTELLIEYE technology, which has a small light in the small hole at the bottom of the mouse, in the face of photosensitive head is a launch infrared light-emitting tube, the luminous tube launch 1500 times per second, and then light head is the 1500 reflected back to the mouse positioning system, in order to realize accurate positioning. So, this kind of mouse can move anywhere without limit.

Mouse according to the mouse button can also be divided into two keyboard, three keyboard, five keyboard and new types of multi-keyboard.

Two keyboard and three keyboard's mouse button function are the same, in general, we don't need center mouse button on three keyboard, but in the use of some special software such as AutoCAD, etc., the key will also have some effect. Such as: use the center button on three keyboard in certain special programs often can have more fast effect, eg. use center button to quick start commonly used commands in the AutoCAD software, which multiplied improve work efficiency. Five keyboard more be used in game, the four key forward, five key back, also can be set to shortcuts. Multi-keyboard is a new generation of multi-function mouse, such as some mouse with a scroll wheel, greatly facilitate the scroll, some new type of mouse in addition to the roller, also increased the thumb button quick keys, such as to further simplify the operating procedure.

Roller mouse and induction mouse

Roller mouse and induction mouse be used very common on a laptop, Rolling the middle small ball in different direction of the mouse, or move a finger on induction plate, the cursor to the corresponding direction, when the cursor is in position, click on the mouse or induction plate, can perform the corresponding functions.

Wireless mouse and 3D mouse

A new wireless mouse and 3D vibration mouse are relatively novel mouse. Wireless mouse is production in order to adapt to large screen display. So-called "wireless", that is, without wires, with battery 7 wireless remote control, mouse has auto sleep function, the battery can use last a year, receiving range within 1.8 meters.

3D vibration mouse

3D vibration mouse is a new type of mouse, it not only can be used as a normal mouse, and has the following features: 1. The full 3D control ability. It has a forward, backward, left, right, up, down six direction, and can combine the right-forward, left-down and so many moving direction. 2. Different shapes from ordinary mouse. Generally consists of a fan base and a controller to activities. 3. Vibration can work, namely the tactile feedback function. Play some games, when you was hit by the enemy, you will feel your mouse is vibration. 4. It is the real three key type mouse. No matter the DOS or Windows environment, the right mouse button and middle mouse button are useful in large.

Wired  wireless mouse

Be modified on the basis of the original optical mouse, wireless transmission by RF wireless, which has internal rechargeable battery. As a wired mouse the world from the first 3R, telescopic line data, can be long or short, it is very convenient to carry.
