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.
