This document discusses design principles for creating intuitive user experiences. It covers Donald Norman's two principles of making things visible and having a good conceptual model. A good conceptual model includes affordances, mapping, constraints, and feedback. The document also discusses user-centered design, which focuses on understanding user needs and creating easy-to-use products. User-centered design involves four key activities and has benefits of intuitive interfaces but also costs more time and money.
