Abstract

Kharkiv National University of Radio Electronics Department of Physics Kharkiv, Ukraine e-mail: anastasiia.melnyk@nure.ua. Now computers are used in a lot of types of human work. To make the interaction with computers user-friendly it was developed new type of user interface, called GUI (Graphical User Interface). However, they have to create new devices to interact with the new type of user interface. This work is devoted to the study of the physical operation principles of a ball-style computer mouse, (this type isn’t used nowadays), and an optical mouse (which we are using every day). Thanks to the mouse, we can control the cursor and execute some commands by using the buttons on the corpus.
