Smoking room of a computer mouse

Hello dear smokers, and other guests of this blog.
Today, I want to talk about a little thing, but our very good friend, without which most of computer games are unthinkable today. Yes, we will talk today about our favorite rodent – computer mouse.

From history, we know that the first computer mouse was presented on December 9, 1968 at the display of interactive devices in California. The creator of her Douglas Carl Engelbart received a patent for her in the same year

Douglas Engelbart was born https://gamesnotongamstop.co.uk/scratch-cards/ on January 30, 1925 in Portland, Oregon in the family of Karl Luis and Gladys Charlotte Amelia MunSon Engelbart. Has Swedish, Norwegian and German roots.
In 1942 he graduated from the Portland school named after Benjamin Franklin and entered the University of Oregon. In the middle of his training, shortly before the end of World War II, he was called up to the ranks of the US Navy, having served two years as a radio operator in the Philippines. During his service, Engelbart first read the article by Wanivar Bush “How can we think”, which inspired him. In 1948, after returning from the war, he finishes training and receives a bachelor’s degree in electrical engineering. In the same year, he was hired by the National Advisory Committee for Aeronading at the Research Center of Aims, where he worked until 1951. After that, Engelbart entered graduate school at the University of California in Berkeley, having received a master’s degree in science in 1953 and the degree of Doctor of Sciences in 1955.
As a graduate student, he helped in the construction of the California Digital Computer project. After receiving a doctoral degree, Douglas remained in Berkeley, where he taught a professor as an assistant to the professor during the year, and then founded a startup for commercializing some of his research in the field of data storage devices.
In 1957 he began work at the Stanford Research Institute located in the city of Menlo Park. Initially, he worked together with Hugh Crane on magnetic components of computers and miniaturization of electronic devices, gradually received more than ten patents (some of which were the result of his thesis). In 1962, he prepared a report containing the alleged research plan and a named strengthening of human intelligence: conceptual Framvork.. The report found support and Douglas received funding from the Agency for Promising Defense Research Development of the United States. In his new ARC scientific center, which was created on the basis of the Stanford Research Institute, he gathered a group of scientists, becoming a driving force for them in the development of the so -called online system. Engelbart and his team have developed elements of a computer interface, such as the output of the raster image to the screen, mouse, hypertext, joint operations and inclinations of the graphic user interface. All this was developed at a time when most people were far from computers, and when the software was mainly written for closed proprietary systems.
In 1967, Engelbart applied for a patent for the device consisting of a wooden case with two metal wheels, which he developed together with Bill Inglish a few years earlier. In the patent, the device is described as "X-Y indicator for the display system". Engelbart later found out that this device received the nickname "Mouse", because the cord coming out of its back was like a tail.
On December 9, 1968, a single autumn computer conference was held in the city of San Francisco, and it was on it that an event occurred, which later christened “Mother of all demonstrations”. The main actors of this demonstration was Douglas Engelbart with his colleagues. They presented to the court to the general public their project of the prototype of personal computers and the future web environment.
From the very beginning, everyone was clear to everyone that something unusual would be presented at this presentation, something that would change the world of technology forever. Engelbart, in the most beautiful location of the spirit, climbed onto the stage, on his head were wearing headphones with a microphone. He sat in front of the demonstration screen at the desktop, on which, in addition to the keyboard, there was some more incomprehensible device. His whole demonstration was devoted to how, in his opinion, work with a computer in the future would look like in his opinion. He devoted the first part of the demonstration to the new capabilities of working with text documents. He changed the size of the text from huge to very small, while the text in the upper part of the screen could not be touched, and in the lower part it could be changed, and vice versa. The text, graphics and videos of the display shift on the scene of the display. There were footnotes inside other documents, and it was possible to move along them! The most unusual thing was that all the actions of Engelbart controlled with the help of the manipulator he invented, which later called a computer mouse with one button. Initially, the scientist planned to place five buttons under each finger of his hand on the device, but due to the fact that in this case the mouse housing would have become even larger, he had to abandon this idea. The mouse’s movement was provided due to two discs, built -in mutually perpendicular, due to this it could move in four directions, which fully corresponds to a change in the coordinates of the object in the two -dimensional coordinate system. Light spot (it was given the name "bug", which was displayed on the screen, moved along the screen after the mouse movements on the surface of the table. With the help of a mouse, Engelbart could click on any word, move it in a document or even move it to another. Engelbart accompanied all his actions by comments, and a triumphant smile was on his face.
After the demonstrations of work with the text ended, Engelbart began the second part of the demonstration. On it, he, along with his colleague, presented the world for the prototype of current video conferences. His laboratory colleague sat down at the same desktop as that of Douglas, with headphones with a microphone on his head. In front of him, as well as in front of Douglas, there was a television camera. During the demonstration, Engelbart and his colleague were able to talk and see each other at the distance, while making manipulations with a general document. This produced a real splash. At the end of the demonstration, the entire hall applauded the scientist and his team. This demonstration anticipated even the most bold expectations, it shows many discoveries made in subsequent years: web documents, screen windows, computer mouse, video conference, collective work on documents

The first to add new development to the package of their computers was Xerox

Xerox Corporation was founded in the city of Rochester in the United States in 1906 under the name Haloid Company and first engaged in the production of photo paper. In 1958, the company was renamed Haloid Xerox, and in 1961 – in Xerox Corporation.
In 1947, she acquired a patent for a copy device invented by Chester Carlson. Copying documents is called Xerography or photocopying – an expression that has established in Russian, and the device itself Carlson proposed to name Xerox (Zirox). The first copier – Model a – was released in 1949. In 1959, the first automatic office copy of the Xerox 914 was released, which allowed to copy documents on simple paper. The device was so popular that in 1961 the company’s profit amounted to about $ 60 million, and by the end of 1965 more than 500 million.
It was the Xerox experts in the scientific center for developments in the Palo-Alto that came up with a computer mouse and a graphic interface in personal computers-they were used in the Xerox Alto computer, called the first personal computer in history. Due to the high cost, this development could not win the market, but Alto ideas were further used by Apple.

The first computer with The Xerox 8010 Information System and its mouse.

In the USSR, a computer mouse came with Macintoshi. Later, our craftsmen also began the production of this indispensable mechanism.
