    Study Notes

    Human-Computer Interaction (HCI) Overview

    • HCI is the study of how humans and computers interact.
    • A key aspect is creating interactive computer interfaces that meet user needs.
    • HCI involves developing, evaluating, and implementing systems for human use, examining surrounding phenomena.
    • Design aims to create interfaces that are easy, effective, and enjoyable to use.

    Interactive Products

    • Many everyday products are interactive (e.g., iPads, smartphones, TVs, ATMs, websites).
    • Usability and functionality are related but distinct.

    Interactional Design and HCI

    • HCI is about optimizing human-computer interaction.
    • HCI includes the design and evaluation of interactive systems.

    Interactive Design

    • Interactive design considers the users, how the product will be used, and where it will be used.
    • The goal is to enhance and support user activities efficiently and usefully.
      • Examples of this are self-checkout systems in stores, libraries, or airports.

    The Process of Interaction Design

    • Interaction design has a cyclical process.
      • Establish requirements
      • Design alternatives
      • Prototyping
      • Evaluating

    Examples of HCI

    • Internet of Things (IoT): Digital systems interact with physical devices (e.g., sensors, actuators)
    • Eye-tracking technology: Measures eye movements to understand how users interact with interfaces.
    • Augmented/Virtual Reality (AR/VR): Allows users to immerse themselves in virtual or augmented environments.

    Basic Activities of Interaction Design

    • Establishing Requirements: Understand target users and their support needs.
    • Developing Alternative Designs: Conceptual and physical design, including features, color, sounds, and design.

    Evaluating Designs

    • Evaluation determines usability and acceptability.
    • Criteria include error rates, appeal, and how well the design meets requirements.

    Interface, Interaction, Experience

    • User Interface (UI): What happens on the screen.
    • Interaction Design (IxD): Process of interaction itself.
    • User Experience (UX): How a product behaves and is used in the real world; includes feelings, satisfaction during use.
    • Crucial factors in UX include the sound of clicks, touch of buttons, colors, and other small details. It's about the whole experience.

    Factors of UX

    • Usability and functionality: how usable and useful the design is.
    • Aesthetics/look and feel: visual appeal.
    • Content, and
    • Emotional appeal (Norman's Model—visceral, behavioral, reflective).

    Usability vs. Usefulness

    • Usefulness: The design functionality meets user needs and supports tasks.
    • Usability: Degree to which an interface is easy to learn, use, protect against errors, and provides support.
      • Useful but not usable, usable but not useful, neither useful nor usable are considerations for designers.

    Usability Goals

    • Effectiveness
    • Efficiency
    • Safety
    • Utility
    • Learnability
    • Memorability

    Usability – Effectiveness

    • How well a product performs as intended (e.g., completing tasks, accessing info, or making purchases).

    Usability – Efficiency

    • How quickly a user can achieve tasks.

    Usability – Safety

    • Understanding error possibilities and recovery procedures within the product.

    Usability – Utility

    • Enables users to complete tasks.

    Usability – Learnability

    • How easily users can learn to use a product.

    Defining the User Interface

    • A user interface (UI) is the means by which users interact with the computer.
    • UI involves all the visible elements of a computer system or program that people interact with visually, audibly, or through touch.

    Input and Output of UI

    • Input: How a person gives instructions to the system. (e.g., using keyboard, mouse, voice, finger).
    • Output: How the system presents information to the user.

    Types of User Interfaces

    • Command-Based: Users type commands to perform tasks (e.g., MS-DOS).
    • Graphical User Interface (GUI): Use graphical elements like icons, menus, etc., to operate systems.
    • Touch Based Interface: The system is interacted via touch screen to control application operations, like opening, closing and running an app.
    • Voice Based Interface: Use voice commands to interact with a device.
    • Gesture Based Interface: User interactions use gestures.

    Key Components of HCI

    • Users
    • Tools
    • Tasks
    • Interfaces
    • Context

    Key Components of HCI-Detail

    • User: Individuals and groups participating in a common task with specific needs, goals, and interaction patterns.
    • Goal-Oriented Tasks: User activities, guided by their intentions and represented digitally by computers.
    • Interface: Part of a system that allows communication between humans and computers (includes elements like screen resolution and color).
    • Context: Environment in which the system is used, influencing its usefulness.

    Importance of HCI

    • Understanding users' needs
    • Making technology accessible
    • Reducing errors and frustration
    • Enhancing interaction efficiency
    • Developing useful and usable technologies
