Study Notes
Human-Computer Interaction (HCI)
- HCI involves an interactive process where user input becomes computer output and vice versa.
- Human cognition limits the ability to process information, influencing interaction design.
- Human Information Processing is often termed cognition, which is foundational in HCI frameworks.
Input-Output Channels
- Vision is the primary source of information for humans but has physical and perceptual limitations.
- Hearing, often considered secondary, significantly contributes to our interaction with technology.
- Touch or haptic perception is a critical input channel that affects user interaction with computers.
- Movement and motor control influence how users interact with technology.
Optical Illusions
- Ponzo Illusion: Demonstrated by Mario Ponzo, shows that background context affects size perception. Two identical lines across converging lines appear different in size.
- Muller-Lyer Illusion: Created by Franz Carl Muller-Lyer, where identical lines appear unequal due to depth cues provided by arrow-like fins at line ends.
Human Memory Types
- Sensory Memory: Buffers for initial stimuli from the senses; includes iconic, echoic, and haptic memory.
- Short-term Memory (Working Memory): Temporary storage for information retrieval, functioning as a scratch pad for rapid recall.
- Long-term Memory: Permanent storage for knowledge, actions, and experiences; it encompasses factual, procedural, and experiential knowledge.
Computer Memory Types
- Primary Memory: Composed of RAM, providing short-term data storage for active processes.
- ROM (Read-Only Memory): Stores permanent data like firmware; non-volatile and retains information post shutdown.
- HDD (Hard Disk Drive): Magnetic storage for data within the computer.
- SSD (Solid-State Drive): Uses flash memory for persistent data storage.
Interaction Models
- Help clarify actions between users and systems by translating user intentions into system responses.
- Interaction paradigms evolved from batch processing in the 1950s to contemporary models involving human-robot interaction.
Types of User Interfaces
- Command Line Interface: Direct user instructions via keystrokes, suitable for experts and repetitive tasks.
- Menu Interface: Offers options on-screen, facilitating ease of use through recognition rather than recall.
- Natural Language Interface: Employs speech recognition or typed inputs but may face challenges with comprehension.
- Query Interface: Guides users through Q&A interactions; often seen in simpler information systems.
- Form-Fill Interface: Simplifies data entry via structured forms, requiring good design for usability.
- Spreadsheet Interface: Evolved from early tools like VisiCalc to modern applications like MS Excel, enabling complex data manipulation.
- WIMP Interface: Predominant interface style based on Windows, Icons, Mice, and Pointer, common in desktop environments.
- Point and Click Interface: Minimal typing, used in multimedia frameworks and ATMs for intuitive navigation.
- Three-Dimensional Interfaces: Utilize virtual reality and 3D workspaces to provide depth and an immersive user experience.
