User interaction typically refers to the ways in which users engage with and navigate through digital interfaces, such as websites, applications, and software programs. This field of research focuses on studying how users interact with technology, including their behaviors, preferences, and experiences. Researchers in this area often explore topics such as usability testing, user experience design, human-computer interaction, and user interface design. By understanding how users interact with technology, researchers can develop more intuitive and user-friendly digital products that meet the needs and expectations of their users.
