Rats-people belong to puma, which means people are stupid!
Mouse interface type: According to the interface type, there are three types of mice: serial mouse, PS/2 mouse and bus mouse. Serial mouse is connected to the computer through serial port, and there are two kinds of 9-pin interface and 25-pin interface. The PS/2 mouse is connected to the computer through a six-pin mini DIN interface, which is similar to the interface of the keyboard. Pay attention to the distinction when using it. The interface of the bus mouse is on the bus interface card.
Working principle of mouse: According to its working principle, mouse can be divided into mechanical mouse and photoelectric mouse. The mechanical mouse is mainly composed of a rolling ball, a roller column and a grating signal sensor. When you drag the mouse, it drives the ball to rotate, and the ball drives the roller column to rotate. The photoelectric pulse signal generated by the grating signal sensor installed at the end of the roller column reflects the displacement change of the mouse in the vertical and horizontal directions, and then the movement of the cursor arrow on the screen is controlled by the processing and conversion of the computer program. The photoelectric mouse device converts the displacement signal into an electric pulse signal by detecting the displacement of the mouse, and then controls the movement of the cursor arrow on the screen through the processing and conversion of the program. Optical mouse uses photoelectric sensor instead of rolling ball. This kind of sensor needs a special pad with stripes or dot patterns.
In addition, the mouse can be divided into two-button mouse, pc mouse, wheel mouse and induction mouse according to its shape. The left and right keys of the two-button mouse and the three-button mouse mark have the same function. In general, we don't need the middle key of the three-key mouse, but this key will also play some roles when using some special software (such as AutoCAD). Roller mouse and induction mouse are widely used in notebook computers. Turn the ball in the middle of the mouse in different directions, or move your finger on the sensor board, and the cursor will move in the corresponding direction. When the cursor reaches the predetermined position, click the mouse or the sensor board to perform the corresponding function.
Wireless mouse and 3D mouse: The new wireless mouse and 3D vibrating mouse are relatively novel mice. Wireless mouse is produced to adapt to large screen display. The so-called "wireless" means that there is no wired connection, but two No.7 batteries are used for wireless remote control. The mouse has automatic sleep function, the battery can be used for one year, and the receiving range is within 1.8 meters. The 3D vibrating mouse is a new type of mouse, which can be used not only as an ordinary mouse, but also has the following characteristics:
(1) has omni-directional stereo control capability. It has six moving directions: front, back, left, right, up and down, which can be combined.
(2) The appearance is different from that of an ordinary mouse. It generally consists of a fan-shaped base and a movable controller.
(3) It has vibration function, that is, tactile feedback function. When playing some games, you will feel the mouse shake when you are hit by the enemy.
(4) It is the real pc mouse. Whether in DOS or Windows environment, the middle button and right button of the mouse are of great use.
Milestone of mouse development:
. 1968, the prototype of the mouse was born;
198 1 year, the first commercial mouse was born, or a mechanical mouse, and a rolling ball mouse appeared;
1983, Logitech invented the first optical mechanical mouse, which became the industry standard in the future;
In the early 1980s, the first generation of optical mouse appeared, which required a special mouse pad with a grid. The high cost limited its application scope.
. 1999, Microsoft and Agilent jointly released the IntelliEye optical engine and the first optical mouse.
196865438+On February 9th, the world's first mouse was born in Stanford University, California, USA. Its inventor is Dr. douglas engelbart. The original intention of Dr. Englebart in designing the mouse is to make the operation of the computer easier, rather than the tedious instructions of the keyboard. The mouse he made is a small wooden box. The working principle is that the ball at the bottom of the mouse drives the pivot to rotate, which drives the rheostat to change the resistance to generate displacement signals. After the signal is processed by the computer, the cursor on the screen will move. Since then, the mouse and PC have formed an indissoluble bond that is difficult to express in words.
Since the computer came into being, the keyboard has been with it and has been playing the role of the main input device. Typing with a keyboard is really good, but when it is used to move the cursor, it shows its limitations. So, Engelbert, who works in NASA and deals with computers all day, had a bold idea-can he use the "point control" method instead of typing on the keyboard?
After years of hard work, in 1982, Engelbert's idea finally came true: a product named "vertical and horizontal movement indicator of cursor position in display system" came out. It has two functions, one is to control the movement of the cursor on the screen, and the other is to replace the enter key. However, its name is too long to be called.
One day, in the laboratory where Engelbert worked, an "indicator showing the vertical and horizontal movement of the cursor position of the system" fell off the computer desk. Because it is connected to the host computer, it hangs in the air and looks like a mouse with a long tail from the side. This scene inspired Engelbert, so the name "mouse" was given to the "indicator that shows the vertical and horizontal movement of the cursor position of the system". When the computer input device "mouse" was used in China, people translated it as "mouse", which appropriately reflected the appearance and function of this device.
The mouse was invented by DouglasEngelbart in 1964. At that time, douglas engelbart worked at the Stanford Research Institute (SRI), an institution sponsored by Stanford University. Douglas Engelbart has long been thinking about how to make the operation of the computer easier, and what means to replace the tedious instructions entered by the keyboard.
In the early 1960s, when attending a meeting, he took out a notebook (not a laptop) that he carried with him and drew a sketch of a device that used two wheels with vertical bottoms to track actions, which was the prototype of the mouse. 1964, douglas engelbart perfected the idea of this device again and made the first finished product. Therefore, douglas engelbart is also called "the father of mice".
At that time, there was no name "mouse". This new device is a small wooden box with two rollers but only one button. Its working principle is that the roller drives the shaft to rotate, the rheostat changes the resistance, and the change of the resistance produces a displacement signal, and the cursor indicating the position on the screen can move after being processed by the computer.
Douglas engelbart and his colleagues nicknamed the device "Mouse" in the laboratory because it dragged a long line like a mouse (like a mouse's tail). At that time, he also thought that the mouse might be widely used in the future, so when he applied for a patent, he named it "X-Y position indicator of display system", but people thought the name "mouse" was more friendly, so he got "mouse".
The popularity of the mouse:
After the mouse was invented, it was first applied to the improved Alto computer system by Xerox on 1973. Unfortunately, at that time, these systems were all used for experiments and research work, and they were not popularized to the public, so the mouse has been unknown.
1979, Steve Jobs, the founder of Apple, was invited to watch Alto and the software executed on the system. Steve Jobs was shocked by the computer technology he saw, and he realized that these technologies represented the future development trend of computers. These technologies include using a mouse as a pointing input device and a GUI (Graphical User Interface) for the operating system. Apple immediately added these functions to its own system, prepared to develop a new type of home computer, and hired more than a dozen technicians from Xerox at a high salary. 198 1 year, Xerox introduced the Star 80 10 computer, which uses a mouse and a GUI operating system. This is the first time that the public knows about the mouse. Unfortunately, due to the high price of this computer, the sales volume is very small. Nevertheless, the mouse has attracted many people's attention and started to be mastered by people.
1983, Apple officially launched the LISA computer, which is the first computer that Apple uses the mouse, and further introduced the mouse to the majority of users, so that users can realize the role of the mouse.
1984, LISA's upgraded product, Macintosh, came out, which was a milestone for Apple and the history of computer development. While bringing rich income to Apple, it also made the mouse enter thousands of households in the past. Later, due to the extensive use of OS/2 and Windows systems, the application of mouse and GUI was further promoted, which made the mouse gradually popular and eventually became the standard configuration of computers. From then on, every computer has a loyal companion, that is "mouse"-mouse.
