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.
