Human-Computer Interaction (HCI) is a multidimensional subject of study that focuses on the design of computer technology, specifically the interaction and interface between humans (users) and devices and systems that include or embed computing. HCI researches how people use technology artefacts as well as how those artefacts may be made to make them easier to use. To better understand and enhance the design, implementation, application, analysis, and assessment of interactive systems, computer scientists engage with specialists in engineering, psychology, linguistics, and social and system organisation in HCI research.

Computer games have progressed beyond their roots as amusement. Educational games, therapeutic games, simulation games, and gamification of utilitarian applications have all been used by researchers and practitioners in novel ways. Individuals and society gain from gaming researchers producing games and using gaming ideas. In the study of games, human-computer interaction (HCI) is crucial. HCI specialists aid in the design and development of better games by evaluating user characteristics, interactions during gaming, and behavioural consequences of gameplay.
