Study Notes
Design Principles
- Guidelines that assist in making decisions about interface elements inclusion or exclusion.
- Visibility: Key controls and functions should be easily noticeable and understandable.
- Feedback: Communication to the user about completed actions or what to do next is essential (e.g., loading signs and pop-up messages).
- Affordance: Objects in an interface should suggest their use to the user.
- Constraints: Limitations that restrict certain actions to minimize user errors (e.g., disabling selection of future dates in a date picker).
-
Consistency: Uniformity across tasks and elements to foster user familiarity, categorized into:
- Internal: Consistency maintained within the layout of the system.
- External: Alignment with other familiar interfaces (e.g., using a floppy disk icon for saving).
- Aesthetic: Uniformity in design aspects like color and fonts.
- Functional: Similar operations yielding comparable outcomes across the interface.
Usability Goals
- Aimed at enhancing the product's ease and effectiveness of use:
- Effectiveness: The ability of the product to perform its intended functions correctly.
- Efficiency: Quick accomplishment of tasks using minimal resources.
- Safety: The design prevents harmful errors and assures user safety.
- Utility: Availability of appropriate functions enabling users to meet their objectives.
- Learnability: User-friendly enough for efficient learning without external assistance.
- Memorability: Ease of recall on how to use the product after a period of disuse.
User-Experience Goals
- Focuses on the user's emotional response to the product:
-
Desirable Aspects:
- Satisfying, helpful, fun, enjoyable, motivating, engaging, pleasurable, exciting.
- Encourages creativity and can lead to fulfilling emotional experiences.

- Boring, unpleasant, frustrating, patronizing, annoying.
- Can lead to feelings of guilt, inferiority, childishness, or gimmickry.
