Study Notes
Human Computer Interaction Concepts
- Slips are unintentional errors, while mistakes occur through conscious deliberation.
- The Problem Space Framework effectively operates within human processing system constraints.
- Attention involves selecting specific things to focus on from available possibilities.
Persona and Usability in Design
- Secondary personas are indirectly affected by the product but are not actual users.
- Personas serve as powerful design tools to address common development challenges.
- Usability goals in HCI mainly include effectiveness, efficiency, and user experience.
Research Methods
- Qualitative research reveals in-depth, multivariate insights about user behavior and preferences.
- Quantitative research provides numerical data regarding user interactions and systems.
- A semantic network is a model of long-term memory.
Cognitive Processing
- Effectiveness in usability refers to how well a system performs its intended functions.
- Efficiency addresses how a system aids users in completing their tasks.
- Cognition encompasses the mental processes during everyday activities.
Interface Design Principles
- Affordance indicates how an object can be used based on its design.
- Visibility refers to how easily users can understand system controls and their effects.
- Constraints help minimize errors in user interaction.
Interaction and Attention
- Focused attention occurs when a person actively listens in a conversation.
- Divided attention is exemplified by multitasking, such as driving while conversing.
- Cognitive effort is reduced significantly during passive actions like listening.
HCI Models and Frameworks
- GOMS stands for Goals, Operators, Methods, and Selection rules, used to analyze user tasks.
- The Waterfall model is a linear approach where each step must complete before the next begins.
- Usability testing is essential for evaluating interface quality through quantitative metrics.
Visual Perception and Color Theory
- The primary colors are red, yellow, and blue; green is not a primary color.
- Approximately 6 million cones in the human eye are responsible for color sensitivity.
Evaluation and Testing
- Field studies are effective for exploring real-world interactions and engagements.
- The structure of an interface includes button placement and layout, critical for user navigation.
- Usability Engineering lifecycle was proposed by Deborah Mayhew.
General Facts
- Roughly 8% of the male population experiences some degree of color blindness.
- Scenarios in design derive from research and are analyzed during the modeling phase.### User Interface and Interaction Design Concepts
- Display Regions: Buttons are individual and isolated regions within a display that users can select to invoke specific operations.
- Undo/Redo Functionality: Redo function was developed as part of the implementation model for the undo operation.
- File Management: Users can explicitly request to place a document in the file system hierarchy through the menu.
- Interface Design: User interface design does not exclude aesthetic concerns but integrates them within a functional framework.
Research and Evaluation Techniques
- User Feedback: Error messages are essential for informing users of mistakes during interaction with systems.
- Feedback Types: Audible feedback may be underestimated as users often claim they dislike such notifications.
- User Personas: Supplemental personas represent users who are not primary or secondary but are influenced by the product.
Usability and Evaluation Principles
- Evaluation Definition: Evaluation compares actual outcomes with desired outcomes.
- Compact Disk Size: The size and shape of a compact disc represent a physical constraint in design.
- Research Types: Qualitative research provides detailed insights into what, how, many, and why aspects of user interactions.
- Data Collection: Note-taking is a simple yet effective method for collecting data during observations and evaluations.
User Interface Elements
- Screen Layout: Panes, frames, and containers on screen organize functional and data elements effectively.
- Prototype Testing: Active intervention is a valuable technique during early design phases, especially when using prototypes.
- User Habit: Information sites with frequent updates attract repeat users versus those updated less often.
Design Methodologies
- Formative Evaluation: Evaluations during the design phase ensure that the product meets user needs.
- Waterfall Model: This linear model necessitates that each step is fully completed before moving to the next.
- Semantic Networks: These networks model long-term memory and represent knowledge connections.
Interaction Techniques
- Visibility Importance: Higher visibility of functions enhances user understanding of next actions.
- Direct Manipulation: Using real-world concepts for tasks within computers is known as direct manipulation.
- Graphical User Interfaces: The WIMP (Windows, Icons, Menus, Pointer) interface style is common in interactive computing.
Cognitive Principles
- Short-Term Memory Limitations: Short-term memory is characterized by limited capacity.
- Human-Computer Interaction: This field bridges the gap between machine interfaces and human understanding.
Color and Sensory Interaction
- Color Theory: Complementary colors are opposites on the color wheel and enhance visual contrast.
- Significant Senses: Sight, hearing, and touch are the predominant senses when interacting with computers.
Quality and Usability Concepts
- Usability Goals: Usability encompasses producing safe and functional systems while achieving user satisfaction.
- Efficiency Definition: In usability, efficiency refers to how effectively a system supports users in task completion.
Behavioral Insights
- Memory Chunking: Easier recall of number strings can occur through grouping and context-based significance.
