    Study Notes

    HCI Process and Methodologies

    • Human-Computer Interaction (HCI) is a field focused on designing, evaluating, and implementing interactive computer systems for human use
    • The HCI life cycle outlines the stages in creating user-friendly computer systems.

    Design Methodologies

    • Activity Theory: Describes frameworks for human-computer interaction, providing reasoning, analytical tools, and interaction design.
    • User-Centered Design: Places users at the center of the design process, giving them a role in collaborating with designers and technical practitioners for design creation.
    • Principles of User Interface Design: Defines seven key principles—tolerance, simplicity, visibility, affordance, consistency, structure, and feedback—used in interface design.
    • Value Sensitive Design: Used to develop technology by understanding the values of users. Three types of studies underpin it -- conceptual, empirical, and technical.
      • Conceptual investigations: Understand the values of users who employ the technology
      • Empirical investigations: Demonstrate designer's understanding of users' values through qualitative or quantitative design research.
      • Technical investigations: Using technologies and designs in conceptual and empirical investigations
    • Participatory Design: Designers collaborate closely with users throughout the design process, incorporating their needs and expectations.
      • HCI practices may include software design, architecture, landscape architecture, and product design, alongside graphic design, urban planning, and medicine.
    • Task Analysis: The procedure to understand users and their workflows.
      • The process involves abstract frameworks, patterns implemented in workflows, and interaction with the GUI.
      • It analyses how users break down tasks and sequence them.
      • Subcategories include requirements analysis, user task analysis, platform constraints assessment (hardware/software analysis), and usability design principles assessment.
      • Hierarchical Task Analysis: Disintegrates tasks into sub-tasks, following a logical sequence for execution.
    • Techniques for Analysis:
      • Task decomposition: Breaking down tasks into sub-tasks and analyzing the sequences.
      • Knowledge-based techniques: Identifying the instructions users need
      • Ethnography: Observing users' behavior in use contexts.
      • Protocol analysis: Observing and documenting user actions, prompting users to think aloud.

    Engineering Task Models

    • ConcurTaskTree (CTT): A methodology for modeling tasks. Consists of tasks and operators portraying chronological associations.
      • Key features comprise a focus on user actions, hierarchical structure, graphical syntax, and sequential operator sets.

    HCI Life Cycle

    • 1. Requirements Analysis: Designers collect information on user needs and preferences through interviews, surveys, and observations. The goal is building user profiles, scenarios, and defined operational procedures to guide the design and ensure the system aligns with user objectives.
    • 2. Design: Translating requirements from the analysis phase into a tangible user interface by sketching, developing wireframes, and creating prototypes to explore various design concepts ensuring the user interface is intuitive, effective, and aesthetically pleasing.
    • 3. Implementation: Transforming the finalized design into functional software or hardware; this involves programming the user interface, testing its functionality/usability, and refining the product based on user feedback.
    • 4. Evaluation: Assessing the system's usability and effectiveness through usability testing, where users perform tasks and provide feedback; further assessments include heuristic evaluations used to identify user interface improvement areas.
    • 5. Deployment: Making the system accessible to target users & offering training, documentation, and support to effectively utilize the system.
    • 6. Maintenance: Ongoing support and updates to ensure usability, relevance, and addressing issues as needed throughout the system's life. This includes improving user functionality and ensuring the system aligns with user needs.

    Software Development Life Cycle (SDLC) Models

    • Software development models outline processes for project development, aligning methods with project objectives.
    • Models specify process steps and order, enabling focused project development.

    Software Modeling

    • Software modeling is the process of creating abstract representations of software systems, guiding developers, designers, and stakeholders concerning the system's structure, behavior, and functionality.
    • Diagrams and modeling languages help visualize and understand complexities in software design for improved planning, development, and management.
