Human computer interfaces emphasize developing a deep understanding of user characteristics and a clear awareness of the tasks a user must perform. hci specialists test design ideas on real users and use formal evaluation techniques to replace intuition in guiding design. The activities involved during this stage are: installing the system, testing, converting from old system to the new system and training the users. file creation and convention: setting up of master files to be used to support the new system. Over the history of computers, we have seen machines evolve from vacuum tubes, plug boards, and transistors, and user interfaces progress from punch cards, graphics, voice and neural user interfaces. In simple language we can say that the operating system is an interface between user and computer. the operating system also enables the user to effectively use the system resources and access other programs.
