The Eight Golden Rules of Interface Design
1. Strive for consistency 2. Seek universal usability 3. Offer informative feedback 4. Design dialogs to yield closure 5. Prevent errors 6. Permit easy reversal of actions 7. Keep users in control 8. Reduce short-term memory load

User-Centered Design
Another cornerstone of HCI is the principle of user-centered design. This approach places the user at the forefront of the design process, ensuring that their needs, preferences, and limitations drive the development of the system. In user-centered design, feedback loops are critical, and iterative design processes are employed to refine the user experience continuously.
