{ "principle": 4, "score": 6, "passes": false, "feedback": "Interface requires too much learning", "evidence_analysis": "Single touchscreen reduces physical complexity but cognitive load remains high", "suggestions": ["Add voice commands", "Implement gesture shortcuts"] } ## The 10 Principles 1. Good design is innovative 2. Good design makes a product useful 3. Good design is aesthetic 4. Good design makes a product understandable 5. Good design is unobtrusive 6. Good design is honest 7. Good design is long-lasting 8. Good design is thorough down to the last detail 9. Good design is environmentally-friendly 10. Good design is as little design as possible "Less, but better" - Weniger, aber besser ### Learn More About Dieter Rams - Wikipedia: Dieter Rams - Vitsoe: Dieter Rams Principles - Book: Less and More - The Design Ethos of Dieter Rams ## Troubleshooting ### Python Dependencies Not Found
