Jakob Nielsen's 10 general principles for interaction design. They are called "heuristics" because they are broad rules of thumb for UX and not specific usability guidelines.
Empathy maps help UX teams visualize user attitudes and behaviors, building a shared understanding of end users while highlighting gaps in existing user data.
Modern day UX research methods answer a wide range of questions. To know when to use which method, each of 20 methods is mapped across 3 dimensions and over time within a typical product-development process.
User interviews have become a popular technique for getting user feedback, mainly because they are fast and easy. Use them to learn about users’ perceptions of your design, not about its usability.
User journeys and user flows both describe processes users go through in order to accomplish their goals, but they differ in scope, purpose, and format.
iOS 26’s visual language obscures content instead of letting it take the spotlight. New (but not always better) design patterns replace established conventions.

An AI agent pursues a goal by iteratively taking actions, evaluating progress, and deciding next steps. Useful agents must be reliable, adaptive, and accurate.
AI can produce polished survey drafts quickly, but experienced human review is still needed to catch subtle survey-design flaws that weaken data quality.
With generative UI, the AI system decides to generate an interactive element or entire product in response to a user need. Vibe coding is when users request the AI to build it.
