The 7-1 rule is a guideline in user interface (UI) design and cognitive psychology that suggests users can effectively process a limited amount of information at once, typically not more than seven items. When designing AI applications or systems, adhering to this rule can enhance usability and user experience by preventing information overload. By limiting the number of visible options or choices presented to users, designers can help them make decisions more efficiently and reduce cognitive strain. This principle is especially relevant in AI-driven applications that involve complex data visualizations, recommendation systems, or interactive interfaces, where clarity and simplicity are paramount for user engagement.
