Study Notes

User-Centered Design (UCD)

Emphasizes understanding and meeting user needs.
Relies on user feedback and knowledge.
Focuses on solving user problems.
Examples: Bluetooth sports earphones, dental equipment.

Activity-Centered Design (ACD)

Prioritizes the activity being performed and the tools used.
Less focus on user needs, more on supporting tasks.
Examples: DJ mixer, slice toaster.

System Design (SD)

Takes a holistic approach, analyzing the entire system including people, devices, and machines.
Focuses on context and functionality.
Examples: Bike sharing system, Amazon Locker system.

Genius Design (GD)

Relies on the designer's expertise and intuition to determine user needs and expectations.
Involves minimal user involvement until the end for testing.
Examples: Juicy Salif, Tamagotchi.

IXD Principles

Affordance: The relationship between the object's properties and the user's capabilities. The way an object can be used.
Signifiers: Indicators that convey the appropriate way to use an object. They communicate where actions should take place.
Experience: The ongoing self-talk that occurs during interaction with products or systems.
Co-experience: Sharing experiences with others through product use.

Typologies of Interactions

Fluent: Automatic and skilled interaction, done without conscious effort.
Cognitive: Requires mental effort and focus on the product.
Expressive: Allows user to build a relationship with the product and evoke emotions.

Experience as a Perspective

Situatedness: Experiences are influenced by cultural context.
Temporality: Experiences are influenced by the time in which they occur.

UX Design

UI (User Interface): The look and feel of a product or web page.
UX (User Experience): The overall experience a user has with the product or system.
Usability: The ease of use and access of a product or system.

Honeycomb Model of UX

Useful: Provides value and addresses user problems.
Desirable: Captivates and engages users.
Findable: Content and features are easy to locate.
Accessible: Navigable by everyone regardless of physical or cognitive abilities.
Credible: Consistent and reliable product that meets expectations.
Valuable: Solves problems and provides a return on investment.
Usable: Easy to use without causing frustration.

Usability

Usability: Concerned with ease and pleasure of use (how).
Utility: Provides functions that users need (what).
Effectiveness: The product performs as expected.
Efficiency: Users can complete tasks quickly and efficiently.
Satisfaction: The user has a positive experience with the product.

Qualitative vs. Quantitative Evaluation

Qualitative: Focuses on understanding "what" and "why". Provides insights and flexibility. Examples: User interviews, focus groups, expert reviews.
Quantitative: Focuses on measuring "how much" and "how many". Generates statistically significant results. Examples: Surveys, UX questionnaires, eye-tracking studies.

Testing in Design

Formal Testing: Conducted with technical equipment, professional personnel, and a structured protocol.
Informal Testing: Conducted without specialized equipment and a simpler protocol.
Summative Testing: Conducted on completed designs for comparison and analysis.
Formative Testing: Conducted during the design process to identify problems, gather feedback, and make improvements.

Prototyping

Prototype: A preliminary model used to communicate design ideas and test user responses.
Fidelity: The level of detail and realism in a prototype.

Qualitative Methods

Interviews

Structured Interviews: Use the same questions and format for all interviewees.
Semi-structured Interviews: Use a set of questions with flexibility for follow-up questions.
Unstructured Interviews: Unbound by a set of questions, allowing for conversational exploration of the topic.

Usability Heuristics

Visibility of system status: Users should be aware of what is happening.
Match between system and the real world: Use familiar language and concepts.
User control and freedom: Provide users with options to undo and redo actions.
Consistency and standards: Use consistent language and terminology across the product.
Error prevention: Design the product to prevent common mistakes.
Recognition rather than recall: Minimize the user's memory load.
Flexibility and efficiency of use: Provide shortcuts for experienced users.
Aesthetic and minimalist design: Avoid unnecessary information.
Help users recognize, diagnose, and recover from errors: Provide clear error messages and solutions.
Help and documentation: Keep documentation concise and easily accessible.

Conducting Heuristic Evaluation

Define heuristics to use for evaluation.
Set a clear evaluation scope.
Choose evaluators with relevant skills and experience.
Provide training for the evaluators.
Familiarize evaluators with product interface.
Identify strengths and weaknesses of the product.
Hold a debriefing session to consolidate findings.
Report the results in a comprehensive and well-structured manner.

Severity Rating

Impact: The extent to which the usability problem affects users.
Frequency: How often the usability problem occurs.
Persistence: Whether the problem is a one-time occurrence or recurring issue.

Cognitive Walkthrough

A task-based usability inspection method.
Utilizes a team of reviewers to walk through user tasks step by step.
Identifies potential usability problems by considering the user's knowledge and expectations.
