User adoption refers to the process of individuals or organizations accepting and using a new technology, product, or system. This research area focuses on understanding the factors that influence users' decisions to adopt or reject a particular technology, as well as strategies to promote adoption and improve user engagement. Researchers in this field may study user attitudes, motivations, preferences, and barriers to adoption, as well as the impact of user adoption on the success of a product or technology implementation. Additionally, user adoption research often involves investigating user experiences, feedback, and interactions with technology to inform design and implementation decisions.
