The origin of the world’s first mouse

Dr. Douglas and his colleague Bill Ingles designed the original prototype of the mouse in 1963, and on December 9, 1968 made the world’s first mouse, which is achieved by using the mouse to move the resistance change. The positioning and control of the cursor. The structure of the original mouse is relatively simple. The bottom is equipped with two mutually perpendicular sheet-shaped circular wheels, each of which drives a mechanical rheostat, which changes the resistance of the varistor when the mouse moves. If the applied voltage is fixed, the strength of the electrical signal fed back by the mouse changes. With this changed feedback signal parameter, the system can calculate its displacement in the horizontal and vertical directions, and then generate a set of Dynamic coordinates that change as the mouse moves. This dynamic coordinate determines the position and movement of the mouse on the screen, so it can replace the four keys of the keyboard up, down, left and right, allowing the user to position the cursor on various parts of the screen. Since the tail of the original mouse dragged a data connection, it looks like a little mouse. Later, people simply called it “Mouse”, which is the name of the “mouse”. On December 9, 1968, he applied for a patent for his design.
Of course, from today’s point of view, this original mouse is indeed quite simple. It uses an all-wooden casing, which is sharp and angular, large and cumbersome, and requires an extra power supply to work properly. It is not convenient to use. Coupled with the use of a large number of mechanical components, over time, the mouse will have very serious wear problems. In addition, the original mouse uses analog technology, and the sensitivity and positioning accuracy are not ideal. All these drawbacks add up, resulting in not many people willing to use it. But as a new born new product, we can’t demand too much from it. The biggest significance of the original mouse is that its birth means that computer input devices have more choices and laid the foundation for the operating system to adopt graphical interface technology. It is hard to imagine how users should operate Windows if there is only a keyboard. Or Mac OS.
Dr. Douglas is the originator of all the mice today. Douglas Engelbart received his Ph.D. in Electrical Engineering and Computer Science from the University of California at Berkeley in 1956 before moving to the prestigious Stanford Institute. In 1989, Dr. Douglas and daughter Cristina founded the Bootstrap Institute in Silicon Valley, USA, and in 1998 won the Turing Award, the most prestigious award in the world of computer science. Dr. Douglas’s field of professional research is in computer theory. As early as the early 1960s, he published an article entitled Amplifying Human Intelligence, proposing the idea of ??using computers as human intelligence amplifiers. Quite forward-looking. For him, inventing the mouse is purely accidental, and it seems insignificant in all his achievements, but the profound computer theories he put forward are far less well known than the mouse. Most regrettably, Dr. Douglas apparently lost an opportunity to become a super billionaire. If he remembers to apply for patents for his ideas in time, then all mouse manufacturers must pay royalties for every mouse they produce today. Whether it is a mechanical mouse, a light machine mouse or an optical mouse.
