Untitled Deck Flashcards
What is the principle of Visibility of System Status?
The system should always keep users informed about what is happening through timely and appropriate feedback.
For instance, showing a ‘Loading’ spinner reassures users the system is processing their request, reducing anxiety.
What does Match Between System and the Real World entail?
The interface should use familiar language, metaphors, and logical structures that align with the user’s mental model.
For example, labeling a feature as ‘Favorites’ instead of ‘Flagged Items’ ensures users immediately understand its purpose.
What is meant by User Control and Freedom?
Users should be able to easily undo or exit unwanted actions without penalty.
What is the importance of Consistency and Standards in design?
Design elements and actions should remain consistent throughout the system and adhere to platform conventions.
For example, a ‘Save’ button should always function the same way across all pages to minimize cognitive load.
How can Error Prevention be achieved in design?
The design should guide users to avoid errors, such as confirming destructive actions or pre-filling form fields with valid defaults.
What does Recognition Rather Than Recall refer to?
Interfaces should reduce the memory burden by making options, features, and instructions visible.
For example, a drop-down menu with all choices listed helps users select the right option without having to remember it.
What is Flexibility and Efficiency of Use?
The system should accommodate both novice and expert users through shortcuts and customizable features.
What is Aesthetic and Minimalist Design?
Interfaces should avoid irrelevant or unnecessary elements, focusing only on what is essential.
A clean dashboard layout ensures that users can quickly locate critical information without distractions.
How should error messages help users?
Error messages should be clear and instructive, enabling users to identify and fix the problem.
For example, instead of ‘Error 404,’ a message like ‘Page not found. Please check the URL or try searching’ is more helpful.
What should Help and Documentation provide?
Support materials should be easy to find and focused on the user’s task.

Define Accessibility in user interfaces.

For example, YouTube has automatic captions and transcripts to assist hearing impairments.
