    Study Notes

    Initial Impact of Products

    • Products create an initial impact based on visceral, behavioral, and reflective aspects.
    • Visceral - first impression based on touch, feel, and appearance.
    • Behavioral - how the product is used, experience with the product, function, performance, and usability.
    • Reflective - impact is influenced by cultural background, individual experience, education, and personal preferences.

    Interaction Framework

    • Abowd and Beale's interaction framework focuses on the relationship between:
      • Tasks: Operations performed to manipulate the product.
      • System: Computer-based system.
      • User: Person interacting with the system.
    • Task analysis helps understand the relationship between the domain, goals, intentions, and tasks of the user.
    • Core language refers to the internal language of the computer-based system.
    • Task language refers to the user's language.
    • The interface acts as a translator between the user and the system.

    Design Principles

    • Learnability: Ensures ease of use for new users.
      • Predictability: Users can anticipate the impact of future actions based on past experience.
      • Synthesizability: Interface supports understanding the cumulative effects of past actions.
      • Familiarity: User can apply prior knowledge and experience to new systems.
        • Guessability: User's expectations align with the system's function.
        • Metaphors: Leverage the user's existing knowledge of metaphors.
        • Affordance: Appearance of objects suggests their functionality.
      • Generalizability: User skills can be applied to new situations.
      • Consistency: Similar interactions should result in consistent responses.
    • Flexibility: Allows for multiple ways to interact with the system.
      • Multithreading: Allows multiple tasks to be managed concurrently.
      • Task Migratability: Functionality can be easily shifted between the user and system.
      • Task Substitutivity: Different inputs and outputs can be used interchangeably.
      • Customizability: User interface can be modified by the user or system.

    Errors

    • Human vs. Computer: The focus should be on collaborative problem-solving rather than assigning blame.
    • The concept of error: Occasional errors are inevitable and should be addressed with a focus on task completion.
    • Types of errors:
      • Slips: Result from unintentional actions, often due to automatized behaviors.
      • Mistakes: Result from conscious decisions and reasoning errors.
    • Types of slips:
      • Capture errors: A frequently performed action overshadows the intended one.

    Computers

    • Input/output devices:
      • Keyboard: QWERTY, Alphabetic, Dvorak, Chord, Phone pads.
      • Pointing devices: Mouse, Trackball, Touchpad, Joystick, Touchscreen.
      • Displays: CRT, LCD, Large displays, Digital paper.
      • VR Systems: 3D displays, Cockpit controls, 3D Mouse, Data glove, VR Helmets, Whole body tracking, VR caves.
      • Sound, smell, haptic interfaces: Special displays, sound feedback, physical controls.
      • Sensors: Biosensing, Environment sensing (GPS, temperature, humidity).
      • Paper input and output: Printing, Scanner.
    • Memory:
      • RAM: Short-term memory, used for currently edited documents.
      • Long Term Storage: Used for permanent data storage.
    • Understanding memory speed and capacity:
      • RAM: Active windowed systems swap out programs that are not currently in use.
      • Memory Management: Understanding the differences and limitations of different types of memory.
