IT History: Mouse Development History [2004-11-5] Mouse development history and knowledge comprehensive mouse development milestones include:. In 1968, the prototype of the mouse was born; 1981, the first commercial mouse was born, still a mechanical mouse, The ball mouse appeared;. In 1983, Luochi invented the first optical mechanical mouse and became the industry standard in the future. The first generation of optic mouse appeared in the early 1980s, it requires special grid mouse pad, High cost limits its scope of use; in 1999, Microsoft cooperated with Agilent issued Intellieye optical engine, as well as the first optical mouse. The sources of the mouse development history: The original name of the PC Home mouse is "mouse", which is a very difficult translated word, many people have a lot of understanding for this word, what "Hismented", "Nice", but No one translated the word directly into a mouse or a mouse. On December 9, 1968, the world's first mouse was born in Stanford University, California, and the inventor of Douglas Englebart. The original intention of Dr. ENGLEBART mouse is to make the computer's operation more easily and instead of the cumbersome instructions in the keyboard. His mouse is a small wood box, the working principle is to drive pivoted by the ball at the bottom, and drive the varistor to change the resistance to generate the displacement signal, the signal is processed, the cursor on the screen can move. Since then, the mouse and PC have ended the impermanement of the expression of speech. The use of mice makes computer operations more simple, and popular WINDOWS operating systems and its related applications have also accelerated the widespread use of mouse between PCs. In a word, the appearance of the mouse makes our work easier and convenient. From the mouse, this little thing is born to the present, and the clock has slowly gone through the history of 32 years. In these 32 years, the mouse has also experienced generations of development and change. 1. From the structure of the mouse, the appearance of the mouse is the mechanical mouse, photoelectric mechanical mouse and photoelectric mouse. Due to the limited mechanical mouse accuracy, the transmission speed is slow and low, so it is basically eliminated, and it is substantially inexpensive. The optical machine mouse has spread into every computer in our lives, but it cannot avoid damage caused by mechanical wear. The optoelectronic mouse is the late, which is divided into two; the old photoelectric mouse needs to use a special grating to make a mouse pad, not convenient enough, and the grid wear will also affect the accuracy; the new mouse uses a name "light eye" New optical engine, higher precision, better reliability. The mouse family also has several brothers in addition to these standards, including Track Balls and other professional mice for different purposes. 2. From the interface of the mouse, the mouse developed from the mouse. The mouse that appeared in ordinary PC applications was serial interface design (trapezoid 9-pin interface), with the gradual increase in serial equipment on the PC machine, The serial mouse is gradually replaced by the PC / 2 interface of the new technology (small circular interface); however, the development of technology is not ended, plug-and-play theory, so that the USB interface has become the development of the future Inevitable trends. For some users with professional requirements, a wireless mouse that uses infrared signals to transmit information with computers, is also a professional fashion.
3. The first mouse in the world is not a very standard double-key mouse, nearly 20 years after the inventions of the mouse, people who have no complaints use the same time. Key mouse, but with the development of computer software technology, people slowly discover that the double-key mouse is no longer good to meet the needs, after all, with the keyboard, the button on the mouse is too small, so People have developed some function keys to adapt to work entertainment requirements; when Internet technology diffuses in a worldwide speed, people have discovered that it is so convenient to add a small axis on the mouse. Browse the web, so that the new generation of roller mouse appears, and now most of the market is dominated by three-bond roller mouse. This roller can also be made as a third button, it is the patented patent invention of Genius, and now we have spread to thousands of households. Although the speed of the mouse is much slower than other computer hardware products, we can surely say that the development of the mouse makes the mouse have become more and more powerful, the range of use is getting wider, give us a computer belt It has been very convenient. I think people will definitely send itself, sincerely say that the mouse is said: "Thank you!" The history of the mouse development Source: IT168 Long-haired ant mouse has been born to today, there are already 35 years, this for 35 years, the mouse, mouse, in performance Still working principle, there are many changes, the only constant is always accompanied by his name - "mouse". Let's simply review the development of this 35 years to mouse, while remembering the ancestors, I also feel the pulse of the development of the pointer technology. Dr. Engilehbart, December 9, 1968, in the world of the world, a wooden small box, a wooden small box, and a box with two mutually perpendicular wheels, and each wheel drives a mechanical varistor to get the X, Y axis The displacement, and there is a button switch to provide a communication signal on the upper surface of the box. The mouse the nose ancestors are very different from today's mouse structure, and even need external power supply to power it to work. (Douglas Engel Bart received a Ph.D. in electrical engineering and computer in the University of California University, USA, later in the famous Stanford Research Institute. In 1989, Douglas Engelbat and daughter Cretina Engelbat is Silicon Valley in the United States. Created the Bootstrap Institute, and obtained the most authoritative awards in the world in 1998. As early as early as early as early as early as the early 1960s, he published a "Augmenting The Human Intellect" The article puts forward the view of the amplifier to be used as a human wisdom. In fact, the mouse is just a small invention in all his outcomes. But he proposed the macro theory of businesses far away It is far from being invented by the mouse in the world.) In 1983, Apple was inspired by the famous STAR computer in Xian Tong, using the mouse as a GUI interface operating tool on the IISA computer in the year. Although this computer is unsuccessful, it provides experience in the Macintosh and Mac OS operating systems launched in the New Year, and the mouse is coming. At this time, the mouse is still an old-fashioned mechanical mouse, but for the initial product already has a new improvement, the mouse ball replaces the unfolirable single-rolling ball, and the single bond design is more flexible, but can be replaced. The standard RS232 serial port design replaces the early independent interface, the basic structure of modern mice has been formed. In 1982, Luochi Company invented the world's first optical machine mouse, and the optical machine structure was the largest inventions in the history of mouse development. That is, this time the structure of the mouse is basically mature, and the mouse market is ruled for 18 years.
In 1984, Luo's first wireless mouse was successfully developed. At that time, it relied on the carrier of the infrared line as a signal. Although this product has failed due to various problems in performance, Logitech has brought a lot of ideas from the later products in wireless innovation. In 1996, the mouse roller invested by Microsoft is a very important invention in the history of mouse development. Today, the roller has become one of the standards of mice. Nowadays, popular rollers are generally included. One is a mechanical roller, that is, with a roller to bring a mechanical potentiometer to obtain information, Many mice in Microsoft use this structure. It has the advantage that the scroll is relatively accurate, but the mechanical structure has wear problems. Order a wheel is that most manufacturers such as photoelectric rolls, Logitech have used this design. Its roller is a gate wheel. The same as a light-emitting secondary tube and thermosensitive secondary tube on both sides of the grid, the operation principle and the optical machine mouse to obtain scrolling information. This long life is relatively long and the feel is very simply, but it is not as good as the mechanical roller above the rolling information. In 1999, Microsoft cooperated with Agilent to launch the Intellimouse Explorer mouse to uncover the prelude of the era of optical imaging mice. The intellieye positioning engine is the world's first optical imaging mouse engine. Its high adaptability and the need for cleaning have become the most sensational mouse product at the time. It is rated as the most outstanding technology products in 1999 by multiple scientific selection. One. (However, because Microsoft hardware products did not formally entered China, the sensational response caused by the Intellimouse Explorer mouse did not affect China's mainland. In 2000, Logitech Company also launched the same type of photovoltaic mouse product, using Agilent H2000 optical imaging Engine, performance is the same as the Intellimouse Explorer mouse. This generation of products is the first generation of optical imaging engines. This generation of photoelectric mouse has some shortcomings that are now well known, such as only 1500 / second refresh rates and 400cpi resolution. The adaptability of the sampling surface is poor, especially for the mirror and the surface of the pattern. In 2001, Agilent launched its own second generation optical imaging engine (A2030, A2051), first launched the product is an elephant, which does not have a major change in the CMOS and DSP engines, through the redesign of the optical engine. The resolution is raised to 800DPI while the refresh rate is increased to 2000-2500 times / sec. However, since this technology improvement does not increase the size of CMOS, it is not obvious that the first generation optical engine performance increase is not obvious. It is precisely because that Agilent has not promoted the second generation of products, only silent and informed replacement of the first generation of products. At the end of 2001, Microsoft ended the cooperation with Agilent, and launched the second generation of Intellieye engines independent, compared with the previous generation, it was extremely significant - Microsoft redesigned the CMOS and DSP algorithm, and the refresh rate was upgraded to an unprecedented 6000 times / Second, the CMOS size is increased to 22x22, while solving the loss of frame and surface adaptability of the optical mouse, and all control circuits are integrated into the same piece of chip, greatly improves the integration of the system. However, the second-generation Intellieye engine optical part is not redesigned, so its resolution is still 400DPI. In 2002, Luochi launched a unique double-headed highlights in the history of photovoltaic mouse to compete with IE3.0. It uses different IAS chips and two second-generation Agilent DSP processors that are different from other Agilent engines. A SPI chip is alternately run to achieve a higher processing speed, although the area of the CMOS does not change, but because the two balun are sampled at different locations, the surface adaptability is better than the mouse in the same time.
