1. Usability
- Learnability: Make it easy for users to learn how to use your product, providing clear instructions, tooltips, and onboarding experiences.
- Efficiency: Streamline user workflows, minimizing the number of steps and interactions required to complete tasks.
- Memorability: Design your product so that users can easily remember how to use it, even after extended periods of disuse.
- Error prevention and recovery: Help users avoid errors by providing clear guidance and validation, and offer easy ways to recover when errors do occur.
Example of Good Usability: Slack
2. Consistency
- Visual consistency: Maintain a consistent visual design, including colors, typography, and UI elements, across all areas of your product.
- Functional consistency: Ensure that similar features and interactions behave consistently, so users don't have to relearn how to perform tasks.
- External consistency: Align your product with established conventions and standards within your industry or platform, leveraging familiar design patterns and interactions.
Example of UI Consistency: Google Suite
3. Feedback
- Visual feedback: Use subtle animations or color changes to indicate the state of UI elements (e.g., buttons changing color when clicked).
- Auditory feedback: Employ sounds to communicate success, errors, or other important events (e.g., a chime when a message is sent).
- Tactile feedback: Utilize haptic feedback (vibrations) to provide a physical response to user actions (e.g., a vibration when selecting an option on a touchscreen).
Example of User Feedback: Apple iOS
4. Flexibility and Efficiency
- Customization: Allow users to personalize your product to better suit their preferences and needs, such as changing color schemes, font sizes, or interface layouts.
- Shortcuts and accelerators: Provide shortcuts, hotkeys, or other efficiency-enhancing tools for expert users, enabling them to complete tasks more quickly.
- Adaptability: Design your product to work seamlessly across different devices, platforms, and input methods, ensuring a consistent experience for all users.
Example of Flexible UI: Trello
5. Emotional Design
- Aesthetics: Craft an aesthetically pleasing visual design that creates a positive emotional response and conveys a sense of quality and professionalism.
- Delight: Incorporate delightful details and interactions, such as engaging animations, humorous copy, or personalized content, to surprise and delight users.
- Empathy: Understand and address the emotional needs of your users, designing your product to support their goals, alleviate their pain points, and foster positive emotions.
Example of Emotion-Infused Design: Headspace
6. User-Centered Design Process
- User research: Conduct interviews, surveys, and observations to gather insights into your users' needs, goals, and pain points.
- Prototyping and iteration: Create low- and high-fidelity prototypes of your product and iterate on them based on user feedback and testing.
- Usability testing: Test your product with real users to identify potential issues, validate design decisions, and gather insights for future improvements.
