The significance of the human-computer interaction (HCI) field lies in its focus on improving the user experience when interacting with technology. HCI studies how people engage with computers and aims to create user-friendly systems that enhance usability, accessibility, and satisfaction. By examining user behaviors, preferences, and cognitive processes, HCI informs the design of software and interfaces that minimize errors, promote efficiency, and foster positive interactions. As technology becomes more integrated into daily life, HCI continues to be critical for developing effective digital tools that meet users’ needs and preferences.
