The idea of human-computer interaction was born as computer technology progressed. The youthful age group of people who are educated and technically skilled are used in research studies in human computer interaction. In Human-Computer Interaction, this study focuses on the mental model. This review study takes many methods, one of which is to highlight current methodologies, findings, and trends in human-computer interaction, and the other is to identify research that was invented a long time

... o but is now falling behind. This study also discusses fidelity prototyping and a user's emotional intelligence to make a product more userfriendly. Why do humans use computers, we investigate in this paper. What is the purpose of a computer system in the human mind? In addition to HCI's computer science. This study examines the literature on humancomputer interaction as well as the technological aspects of human-computer interaction using digital technologies. All these challenges are explored and recommendations for designing good human-computer digital devices are provided. Digital devices have continued to increase in efficiency and processing capacity thanks to advancements in both hardware and software. However, many of these systems are growing in size and complexity. While such intricacy normally offers no problems for most users, it frequently creates impediments for users while utilising digital devices. Typically, when designing those digital devices, the human-computer interaction is overlooked.
