    Study Notes

    Differences in Priorities

    • Human-computer interaction (HCI) focuses on user experience while software engineering prioritizes system performance and technical requirements.
    • Balancing technical constraints with usability goals is a challenge in integrating HCI and software engineering.
    • HCI involves creative design processes while software engineering requires a structured and methodical approach.

    Collaborative Roles

    • UI/UX designers from the HCI side work closely with software engineers, focusing on user interface & interactions, while engineers ensure feasibility within the system.
    • Front-end developers bridge the gap between HCI & software engineering, implementing the user interface designed by UX specialists while ensuring technical integration with back-end services, data management, and performance optimization.
    • Agile teams translate user stories derived from HCI research into technical tasks for engineers, fostering collaboration between the two fields for a seamless user experience.

    Prototyping Techniques

    • Prototyping techniques are essential for testing and refining ideas before full-scale production.
    • The primary goal of prototyping is to identify potential usability issues and improvements early in the design process.

    Paper Prototyping

    • Simplest form of prototyping using sketches on paper or whiteboards, used in the early stages of design to quickly conceptualize the user interface and interaction flows.
    • Advantages: Fast, inexpensive, easy to iterate, encourages creativity.
    • Disadvantages: Limited interactivity, can not fully simulate the user experience.
    • Use Case: Early brainstorming sessions to validate ideas and gather initial feedback on layout and flow.

    Low-Fidelity Prototyping

    • Rough representations of the design created with basic shapes, placeholders, and minimal detail, focusing on layout, structure, and user flows.
    • Tools: Balsamiq, Sketch (for wireframes), Axure RP (basic wireframes).
    • Advantages: Quick to create and iterate, focuses on core functionality, helps to map out user flows and overall structure.
    • Disadvantages: Lacks detail and visual elements, limited usability testing due to lack of interactivity.
    • Use Case: Validating information architecture, layout, and navigation flows.

    Wireframe Prototyping

    • Skeletal outlines of a digital product defining the placement of UI elements without focusing on aesthetics.
    • Tools: Figma, Sketch, Adobe XD, Axure RP.
    • Advantages: Clear understanding of UI element placement, quick to create and iterate, focuses on functionality not aesthetics.
    • Disadvantages: Lacks visual details, limited interactivity.
    • Use Case: Visualizing the layout of UI elements, testing user flows, identifying potential issues in information hierarchy.

    High-Fidelity Prototyping

    • Highly detailed and interactive prototypes resembling the final product, allowing for extensive usability testing.
    • Tools: Figma, Sketch, Adobe XD, InVision, ProtoPie.
    • Advantages: Realistic user experience, allows for in-depth usability testing, identifies issues with user interface and interactions.
    • Disadvantages: Time-consuming to create, requires more technical expertise, can be expensive to create.
    • Use Case: Finalizing the user interface, testing user interactions, gathering detailed feedback before development.

    Interactive Prototyping

    • Interactive prototypes allow users to interact with a functional representation of the design, simulating real-world interactions.
    • Tools: Figma, Sketch, Adobe XD, InVision, ProtoPie.
    • Advantages: Realistic user experience, allows for in-depth usability testing, identifies issues with user interface and interactions.
    • Disadvantages: Requires more technical expertise, can be time-consuming and expensive to create.
    • Use Case: Testing user interface, gathering feedback, validating user flows, performing A/B testing.

    Psychology and Human Factors

    • Understanding users' cognitive processes, perception, and interaction with technology is crucial for user-friendly design.

    Cognitive Psychology

    • Focuses on understanding how users process information, make decisions, and solve problems.
    • Key concepts:
      • Attention: Interfaces should minimize distractions and highlight important information.
      • Memory: Designing interfaces with clear visual cues and consistent layouts helps users remember how to use the system effectively.
      • Perception: Ensuring that UI elements are easily perceptible and distinguishable helps in better user interaction.

    Human Factors

    • Addresses the physical interaction and ergonomics of human-machine systems.
    • Key concepts:
      • Accessibility: Designing interfaces for all users, including those with disabilities.
      • Ergonomics: Optimizing the physical interaction with the system to minimize fatigue and discomfort.
      • Usability: Making sure the system is easy to learn and use.

    Web User Interface Popularity

    • Web user interfaces (UIs) are popular due to their cross-platform accessibility, ease of deployment and maintenance, cost-effectiveness, and the evolution of web technologies.

    Cross-Platform Accessibility

    • Web UIs are accessible from any device with a web browser, ensuring universal access.
    • Responsive design techniques provide consistent user experiences across various screen sizes and devices.
