Classification of the mouse

The mouse is our essential computer accessories, daily use, each one of us can not do without it, but you know how many types? Please read the following article:
1. Mechanical mouse
Machinery the mouse mainly from bowling, roller column and raster signal sensor. When you drag the mouse to drive Bowls rotation Bowls and led the the roll column rotation, mounted on the photoelectric pulse signal generated by the grating signal sensor roll column ends reflects the displacement of the mouse in the vertical and horizontal directions, and then through the computer The processing and conversion of the program to control the movement of the cursor on the screen of the arrow.
Original mouse exists only as a technology demonstrator goods, not really mass production manufacturing. Mouse began to be formally introduced to the PC, the corresponding technical innovation. Rely on different resistance to locate principle has been completely abandoned, replaced by pure digital technology mechanical mouse.
Different from the original mouse, perpendicular sheet circle round the bottom of this mechanical mouse, but switch to a four-way scrolling the glial small ball. This little ball when it is in the scroll drives a pair of rotary shaft rotation (respectively X rotary shaft, Y shaft), the end of the shaft has a circular decoder wheel, decoded on the wheel with the conductive metal sheet and the brush in direct contact . When the shaft is rotated, the conductive metal sheet and the brush will successively contact, two forms of the “ON” or “OFF” appears, the former corresponds to the binary number “1″, which corresponds to the binary number “0″. Next, the binary signal is sent to the mouse inside a dedicated chip for analyzing process and generate the corresponding coordinate change signal. As long as the mouse to move in the plane, the ball will be driven shaft rotation, thereby enabling the decoding wheel off the situation change, generating a bundle of different coordinate offset, and the reaction to the screen, that is, the cursor with the mouse moves.
Compared with the original mouse mechanical mouse is much improved in terms of usability, improved responsiveness and accuracy, low cost manufacturing, to become the first large-scale popular mouse products. However, due to its use of purely mechanical structure, the positioning accuracy is difficult to satisfactory, with frequent contact with the brush and decoding wheel wear more powerful, direct impact on the life of the mechanical mouse. After popular for some time, it is the same low-cost “light machine mouse” substituted, the latter is precisely now on the market is still commonly called mechanical mouse.
2.light machine mouse
In order to overcome the purely mechanical mouse accuracy is not high, the drawbacks of mechanical structure is easy to wear, Logitech designed in 1983, the first optical mechanical mouse, generally referred to as “light machine mouse. Ray machine mouse is modified by introducing the optical technology to improve the accuracy of positioning of the mouse the mouse on the basis of purely mechanical. With the pure mechanical mouse, opto-mechanical mouse has a gelatinous small bowls and connected to the X, Y shaft, and the difference is that the light machine mouse is no longer circular decoder wheel, replaced by the two with gate seam raster code disc, and the increase of the light emitting diode and the photosensitive chips. When the mouse is moved on the desktop, the bowls will be driven by the X, Y-shaft two grating code wheel is rotated, the X, Y light emitting diode emits the light would be irradiated in the raster on the code wheel, seam exists because the raster code wheel gate, direct exposure to the detection of two light-sensitive chip head at the right time diode emits light can be sewn through the gate. If the received optical signal, a photosensitive chip will produce a signal “1″, in the absence of receiving an optical signal, then the given signal “0″. Next, these signals are fed to the dedicated control chip operations to generate the corresponding coordinate offset, to determine the position of the cursor on the screen.
With this principle, light machine mouse in the accuracy, reliability, and responsiveness are much higher than the the original purely mechanical mouse, and to maintain a low-cost advantages, quickly swept the market after the introduction of the purely mechanical mouse is rapidly replacing. Suffice it to say, the era of true mouse ray machine mouse, and it continues to this day has not ended, most of the low-grade mouse on the market today for the types. However, light machine mouse also has its inherent defect: the bottom of the ball are not dirt, after a period of use, the two shafts will be due Nianman dirt affect the light by, appear like such as a mobile insensitive, the cursor block the problem, so in order to maintain good performance, light machine mouse require from time to time the ball and the shaft must be for a thorough cleaning. Use in dusty, even demanded that every two or three days to clean once. In addition, with the use of time, light machine mouse can not maintain the original good working condition, response sensitivity and positioning accuracy would decline, durability unsatisfactory.
As the name implies, light machine type mouse is a combination of a photoelectric and mechanical mouse. It on the basis of the mechanical mouse, the most worn-contact brush and decoding round LED changed to non-contact optical path components on the radio. When the ball rolling, the X, Y direction of the roller, driven by the code wheel rotates. Mounted on the sides of the code wheel has two sets of light emitting diode and a phototransistor, the LED light beam emitted sometimes irradiated onto the phototransistor, and sometimes were blocked, thereby generating a pulse sequence with a 90 ° phase difference of the two groups. The amount of the number of pulses representative of the displacement of the mouse, while the phase indicates the direction of movement of the mouse. As a result of using a non-contact member, to reduce the wear rate, thus greatly improving the life of the mouse and to increase the accuracy of the mouse. The light machine mouse there is no difference between appearance and mechanical mouse, do not open the casing of the mouse is difficult to distinguish.
3.Optical Mouse
Photoelectric mouse is a displacement, the displacement signal is converted into an electric pulse signal, and then through the processing and conversion of the program to control the movement of the cursor on the screen of the arrow by detecting a mouse. The optical mouse with photoelectric sensor instead of the bowls. Such sensors require a special pad used in conjunction with a striped or dotted pattern.
With light machine mouse development the same era, a completely mechanical structure of the digital optical mouse. The design of this optical mouse original intention is to increase the precision of the mouse to a whole new level, to fully meet the needs of professional applications. This optical mouse does not have a traditional bowls, shaft and other design, the main components of the two light emitting diodes and photosensitive chip, the control chip and a reflection plate with a mesh (equivalent to a dedicated mouse pad). Optical mouse work must be moving in on the reflector X light-emitting diodes and Y light-emitting diodes will emit light shines on the reflector, then the light will be reflected by the reflector back, passing through the lens components after irradiation of the photosensitive chip. Photosensitive chip optical signals into a corresponding digital signal will be sent to the positioning chip special processing, and then generates the XY coordinate offset data.
Such optical mouse precision index certainly improved, but it exposed a large number of defects in the subsequent application. First, optical mouse must rely on the reflecting plate, the position data is entirely in accordance with the reflection plate in the grid information to generate, if the reflecting plate is somewhat dirty or worn, the optical mouse can not determine the location of the cursor. If the reflector plate inadvertently been severely damaged or lost, the entire mouse came to be scrapped; Second, optical mouse use is very humane, its direction of movement must be perpendicular to the reflective panel grid texture, impossible for the user to quickly cursor directly from the upper left corner of the screen to move to the lower right corner; Third, the cost of the optical mouse is quite high, the price of a few hundred dollars in today’s point of view and there is nothing remarkable, but in those days people are only willing to pay around $ 20 for the mouse funds, the high price of the optical mouse does not seem unreasonable to expect. Since there are a large number of drawbacks, such optical mouse does not pop, at best, only in a few specialized mapping occasions to obtain a certain degree of application, but with the ray machine mouse comprehensive popular, this optical mouse soon market eliminated.
4.Optical Mouse
The optical mouse is an advanced mouse designed by Microsoft. It using NTELLIEYE technology, there is a small hole in the bottom of the mouse small photosensitive head, the face of the photosensitive head is a transmitter of infrared light emitting tube, the light emitting tube second outwardly fired 1500 times, and then the photosensitive head will be 1500 times the reflection back to the positioning system of the mouse, in order to achieve accurate positioning. Therefore, this mouse can be in any place unrestricted movement.
Optical mouse fail miserably, but the work of the all-digital, non-mechanical structure as well as high-precision advantages allow the industry it attention, If we can overcome its birth defects will carry forward its advantages, to create a set of high-precision, high reliability and The durability of the product is entirely feasible technically. The first to achieve results in this area is Microsoft and Agilent Technologies. In 1999, Microsoft introduced the second generation of a product called “IntelliMouseExplorer” optical mouse, this mouse is a Microsoft and Agilent to develop IntelliEye optical engine, because it is more by means of optical technology, it is also said by the outside world “optical mouse”.
It retains the optical mouse high precision mechanical structure, etc., but also has a high reliability and durability, and uses the process Needless to clean and also maintain a good working condition, quickly caught the industry’s attention after birth. In 2000, Logitech and Agilent to launch related products, Microsoft and later to conduct independent research and development work at the end of 2001 to launch the second generation IntelliEye optical engine. Optical mouse formed two camps Microsoft and Logitech and Agilent Technologies have mastered the core technology of the optical engine, but it did not involve a mouse products manufacturing optical engine products, but to the third-party mouse manufacturers , currently on the market of non-Microsoft, Logitech brand mouse almost all of its technology.
Structure optical mouse with all these products have a lot of differences, it’s no scroll wheel on the bottom, nor need the help of a reflective plate positioning the core components of the light-emitting diode, miniature cameras, optical engine and control chip. Work when the light emitting diode emits light to illuminate the surface of the bottom of the mouse, while the miniature camera to a certain time interval continuous image capturing. Produce different images of the mouse during the movement is transmitted to the optical engine for digital processing, and finally by the positioning in the DSP chip in the optical engine for analysis of the image produced by the digital matrix. Adjacent two image there will always be the same features, by contrast a change of position information of these feature points, it can be judged that the direction and distance of movement of the mouse, the results of this analysis is eventually converted to the coordinate offsets to achieve the positioning of the cursor .
There is no doubt that the set of perfect indicators in an optical mouse was born on the doomed will have a bright future, despite the expensive optical mouse in the early years, the consumer market, few people interested, but after 2001 gradually been changing the mouse manufacturers have introduced optical mouse products, consumers also recognize its advantages where. Since then, manufacturers vigorously promote consumer attitudes to change, to spend more money to buy an optical mouse users increasing. Optical mouse technology to move forward with a resolution of up to 800dpi precision, the refresh rate of up to 6000 times per second, in the fierce competitive games can also be flexible, color blindness troubled optical mouse has also been a good solution . Costs continue to decline, coupled with the smooth production allowed the hundred or so can be bought for a fairly good optical mouse (cheap products may be as long as 30 to 40 yuan), the optical mouse in the past two years into the explosive long-term, the vast majority of the installed base to it as the product of choice. And, in stark contrast with this mouse twilight ray machine, market share is shrinking, although low-level field, there is a certain demand, but replaced the optical mouse, and ultimately exit the market tend to behave very obvious.
5.multi-button mouse
In addition, the number of keys in the mouse can also be divided into a two-button mouse, three-button mouse, five-button mouse, and a new multi-button mouse. Two-button mouse and a three-button mouse left and right buttons function exactly normal circumstances, we do not need the middle button of the three-button mouse, but using some special software (such as AutoCAD), this key will also play some role. Such as: a three-button mouse button can often play the role of duplication of efforts in some special programs, such as AutoCAD software can take advantage of quick start in the key common commands, exponentially improve work efficiency. The five-button mouse is used for games, four key forward, key back, also can be set as a shortcut key. Multi-button mouse is a new generation of multi-function mouse, if the mouse has a scroll wheel, convenient flip up and down, some new type of mouse thumb keys, etc. In addition to the wheel, quick key, further simplifying the procedures .
6.Roller and sensing mouse.
Scroll mouse and sensing mouse on a laptop with a very common, turn the the mouse middle of a small ball in different directions, or move your finger in the sensor board, the cursor will move to the corresponding direction when the cursor reaches the predetermined position, press the click of a mouse or induction plates, you can perform the corresponding function.
7.Wireless and 3D mouse
Wireless mouse and 3D mouse: new wireless mouse and 3D vibration mouse novel mouse.
Wireless mouse in order to adapt to the large-screen display production. The so-called “wireless”, that is, there is no wire connection, generally use the 27M, 2.4G, Bluetooth technology with a host of wireless communication, wireless remote control with two AAA batteries, mouse automatic sleep function, the battery can be used in the previous year, the reception range less than 1.8 m.
8.3D vibration mouse
3D vibrating mouse is a new type of mouse, it not only can be used as an ordinary mouse use, and has the following characteristics:
With a full three-dimensional control. It has a front, rear, left, right, upper and lower six moving direction and the moving direction of the front right, lower left, etc., and can be combined.
Different shape and ordinary mouse. Generally constituted by a fan base and an active controller.
Tactile feedback function has a vibration function. Play some games, when you have been hit by the enemy, you will feel your mouse vibration.
Is a three-button mouse. DOS or Windows environment, mouse button and right-of much help.
9. Wired wireless mouse
Improved wireless transmission through the RF wireless optical mouse on the basis of the original, while the internal rechargeable battery. Used as a wired mouse from 3R world’s first data retractable cord can be short or long, very convenient to carry.
10. Radiation mouse
Use of the principle of energy conversion, and rely on the hysteresis loss, remanence loss, domain wall resonance, eddy current losses, resonance loss and rely on the electronic polarization of the medium, the interface polarization decay absorbing electromagnetic waves and can effectively absorb the electromagnetic wave of 10MHz — 3000MHz It has a frequency bandwidth, thinner and adsorption ability to make a sharp attenuation of electromagnetic energy into harmless heat volatilization is a clean and complete attenuation of electromagnetic pollution senior utility products. The electromagnetic shielding band 10MHz-5000MHz absorption and attenuation of electromagnetic waves more than 95%.
11. Vertical mouse
HE original concept of the concept of the vertical mouse, which has been introduced would attract the attention, the so-called “vertical” refers to the user when using the mouse, palm and desktop near vertical state of the. Ordinary mouse use in the process, the user’s arm is horizontal movement to control it, a long time, it is easy to cause arm fatigue, lesions of the arm joints and even lead to serious, long-term use of the common computer mouse also probably because of the small mouse suffering from occupational diseases. The mouse is one of the highest number of computer peripheral products we use every day, this is especially for office users more frequently.
12. Finger mouse
Ring Mouse – an innovative, completely subvert the conventional finger wearable mouse. Special finger ring design, optical mouse sensitivity, dexterity, lightweight design, does not occupy space, to wear while typing, notebook computer users, especially friends outside using a computer for a long time the best use of tools, when you used to ensure that attracted many curious glances, more magical side to use while typing Oh, that is used in the keyboard on, this is really amazing! Finger mouse has become a modern society, one of the more popular household items!
