Study Notes
Course Overview
- Recommended textbook: "Designing the User Interface" by Ben Shneiderman and Catherine Plaisant.
- Grading breakdown: 60% Final Exam, 10% Oral Exam, 20% Project and Assignments.
- Section materials include React for web development and React Native for mobile applications.
Course Outline
- Introduction to user interface and experience principles.
- Key topics: Learnability, Visibility, Efficiency, Error management, User-centered design, Task analysis.
- Focus on design generation and user interface architecture, including layout and input/output.
- Emphasis on user testing and experimental analysis specifically in mobile user interfaces.
Key Terminology
- UX (User Experience): Overall interaction with a product or service, encompassing user sentiment and effectiveness.
- UI (User Interface): Design focus aims to enhance user experience, requiring minimal effort for maximum results; involves visual design aspects.
- HCI (Human-Computer Interaction): Integration of user interface and user experience consideration.
Importance of Usability
- Usability assesses how easy interfaces are for users; methods enhance design processes.
- Attractive UI can mislead users about the usability of a system, as they might incorrectly blame themselves for errors.
- Usability differs from attributes like reliability or security since issues may go unreported if they are not critical.
Usability Components
- Learnability: Ease of completing tasks during initial use.
- Efficiency: Speed of task completion post-learning phase.
- Memorability: Ability to reestablish proficiency after a period of disuse.
- Errors: Frequency and severity of user errors and ease of recovery.
- Satisfaction: User pleasure derived from the design.
- Utility vs Usability: Utility refers to functionality, while usability measures ease and pleasantness in using those features.
Importance of Usability in Web Design
- Essential for website success; difficult interfaces lead to higher user abandonment.
- Users may leave if they cannot find products or if information is unclear.
- The principle of ecommerce states: if users cannot find a product, they cannot buy it.
Usability Improvement Process
- Usability evaluation occurs at every design stage.
- Initial steps include testing existing designs and competitors' interfaces.
- Observational studies in natural user environments inform design decisions.
- Create and test paper prototypes for new design ideas.
- Refine designs through iterations based on testing outcomes.
- Compare final designs against established usability guidelines.
- Post-implementation testing ensures effectiveness.
Methods to Enhance Usability
- Reduce loading times for web pages.
- Uphold design consistency across all sections of the site.
- Ensure that the site is responsive to various devices and screen sizes.
