Study Notes
Interface Design Guidelines
- Guidelines are suggestions of rules to enhance interface creation and establish appearance and behavior.
- Four main roles of guidelines: raising awareness, assisting in choices, offering strategies, and supporting evaluation.
- Key principles for effective interface design:
- Understand the user population (e.g., provide shortcuts for experienced users).
- Reduce cognitive load by minimizing the amount of information users need to remember.
- Engineer for errors by implementing preventive measures and informative error messages.
- Maintain consistency and clarity through standard operations and appropriate metaphors.
User-Centred Design Principle
- Modern systems must adapt to the user rather than forcing users to adapt to the system.
- Core principles of user-centred design:
- Users should have control over the interface.
- Reduce memory load for users.
- Ensure consistency in the user interface across applications.
Users in Control Principles
- Allow flexibility for input through keyboard or mouse.
- Interfaces should be interruptible, enabling users to change focus as needed.
- Provide helpful, descriptive messages to assist users during navigation.
- Implement immediate and reversible actions with clear feedback.
- Create navigable paths with clear exits and meaningful options.
- Enable direct manipulation of interface objects for user interaction.
- Customization options should be available for individual user preferences.
- Ensure accessibility for users with varying skill levels.
Reducing User's Memory Load
- Alleviate short-term memory demands through recognition-based interactions.
- Use visual cues to inform users and guide their actions.
- Defaults, undo, and redo options should be included to enhance forgiveness.
- Incorporate interface shortcuts to improve user efficiency.
- Progressive disclosure aids context and reduces cognitive overload.
- Utilize an intuitive object-action syntax for ease of understanding.
- Organize information to promote visual clarity.
Consistency in User Interfaces
- Consistency is vital for usability; it allows for knowledge transfer across different interfaces.
- Users benefit from reliable reference points during navigation.
- Presentation consistency ensures information is logically and visually uniform.
- Elements that are unchangeable should maintain a standard font and color throughout the program.
- Behavioral consistency means that interface controls must function the same way across various programs and situations.
- Interaction techniques should be uniform to avoid confusion and enhance familiarity.
