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.
