The document discusses interaction design principles such as perceived affordances, which refer to visual cues that suggest how objects can be interacted with. It emphasizes making relevant interactive parts visible and providing feedback to users. Designers should leverage affordances by mimicking real-world physical properties, use action words to indicate interactions, and focus on functions over controls to prevent feature creep.
