Human Computer Interaction (HCI) is a modern approach that has been the foundation of development of hardware, software and interaction programs that integrates the user’s experience with the desired results. In this research paper, the history of HCI is investigated and how there have been several changes over time as a result of the changing users’ needs. The goals and purposes of HCI including increasing efficiency, safety, and effectiveness of users usability are also discussed. The Norma’s model that illustrate the cycle required in development of an effective HCI system is illustrated using some of the principles of usability; interactions and interactivity. The paradigm of how computers act as social factors in HCI are discussed with an emphasis on how the interpersonal communication should be included in computer systems to maximize utility. Under the machine agency theory, virtual individuals in the computer systems use non-verbal communication styles such as eye contact to promote users’ experience. The current and future trends in HCI are analyzed to include the use of robots, Artificial intelligence, and virtual reality to enhance the use of HCI principles
