Abstract: Human factors influence the way people interact with computers and applications. It is related to the activities of computer users physically and mentally. There is a lack of research on the human computer interaction as a decisive and important factor in designing software applications. Systems analysts usually don’t focus on HCI while designing the proposed system when in fact they are designing software applications based on user requirements. The SDLC method neglects to take human factors in consideration in the user interface design stage. Although, there is plenty of research on usability but the topic of human factor consideration is still a version domain. This research aims at investigating how to take the human factors in consideration when designing software application.
