Study Notes

Importance of Understanding the Problem Space

Provides clarity on design purpose and methodology.
Saves time, effort, and financial resources during the design process.
Encourages refinement of ill-conceived ideas before finalizing designs.
Aids in preliminary considerations of user experience and suitable design types.
Understanding the problem equates to understanding the users.

Lessons from Havana Experience

Proper context is established through problem comprehension.
Problem understanding can guide alterations in solutions.
Involving users in problem assessment fosters acceptable solutions.

Levels of Engagement with Users

Initial interaction with community leaders offers surface-level insights into the problem.
Broader community engagement (citizens, police, leaders) yields a complex understanding, albeit still superficial.
Focused discussions with selected community members deliver an in-depth problem understanding and potential collaborative solutions.

Approaches to Interaction Design

User-Centered Design prioritizes user input for guiding design solutions.
Activity-Centered Design focuses on user behavior during specific tasks rather than their goals.
System Design centers on the system’s components while users define the system’s objectives.

Data Gathering Techniques

Interview Methods:
- Structured: Best for clear goals.
- Semi-structured: Flexible, guided conversation.
- Unstructured: Open-ended, exploratory discussions.
Questionnaires: Asynchronous data collection.
Observation: Direct or indirect examination of user interactions.
Focus Groups: Collaborative discussion for data collection.

Data Recording Methods

Note-taking combined with photos provides basic insights.
Audio recording allows for better focus during interviews.
Video recording is intrusive but can provide comprehensive data.

Interview Techniques

Unstructured interviews support exploratory discussions but can be lengthy in analysis.
Structured interviews use standard questions for comparison.
Semi-structured combines elements of both approaches, maintaining flexibility while ensuring key topics are addressed.

Understanding Human Capabilities in Design

Designers must grasp cognitive psychology to build systems accommodating user needs and limitations.
Key cognitive components include information processing, perception, attention, and memory.

Sensory Perception in HCI

Five main human senses: sight, hearing, touch, taste, and smell.
Visual perception is critical, influencing design through aspects like size, depth, and brightness.

Theories of Visual Perception

Constructivism: Suggests perception involves processing images with contextual information aiding recognition.
Ecological: Proposes that knowledge of the world is necessary for object recognition.

Contextual Information in Design

Similar interface elements can have different meanings in varying contexts.
Recognizing user diversity and context-specific interpretations is vital for effective UI design.

Heuristic Evaluation and Usability Testing

Heuristic evaluations by experts can identify usability issues.
Usability testing typically involves end users and combines qualitative and quantitative data collection methods.
Key aspects include user satisfaction, error frequency, and task completion time.

Observation Techniques

Observation may occur in natural or controlled settings, focusing on who, where, and what.
Ethnography includes comprehensive methods such as direct observation and diary studies, allowing for unstructured data collection.

Principles for UI Design

Recognize User Diversity and follow the Eight Golden Rules of design to enhance usability.
Emphasizes consistency, user control, informative feedback, and error prevention.
Maintain clarity in design through consistent terminology, layout, and action sequences to improve user experience.
