The doctor's team was entrusted with the creation of the ARPANET Network Information Center. And it was as a side effect of the NLS project that the first manipulator was born, which was called a computer mouse (or in the language of a scientific report, the "X and Y position indicator"). This is a genius device, without which any workflow on the computer is slowed down now, developed by chance. Simply the existing manipulators (joysticks, light pens, and keyboard) slowed down the window environment,...

It all started in the Stone Age when the Neanderthals had to take care of warming during the Ice Age. Along with the hide capes, they used skin fragments that were wrapped around the leg and fixed with leather cords on top.
