Back to the history of the mouse. .
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".
