User types refer to the different categories of individuals who interact with a system, product, or service. These categories are often defined by their specific needs, behaviors, and levels of expertise. Common user types include novice users, who are new and require guidance, and expert users, who are familiar with the system and seek advanced features. Understanding user types helps designers and developers create tailored experiences. For instance, user personas can be developed to represent these types, allowing teams to focus on the unique requirements of each group. This approach enhances usability and satisfaction across diverse user bases.
