These parts of the body are monitored by web cameras and with their help the user moves around the virtual keyboard shown on the screen. In this way the user is able to utilize their own PC. Moreover, through winking an eye he/she can virtually press a button and write the required symbol. The whole software for detection system was established in a development environment of the Visual Studio 2010 from Microsoft company. The main advantage of our solution is a cheaper price in compare to any existing solutions. By this fact the solution is possible to use even in third countries like in Africa continent.
