Study Notes
Overview of HCI
- Human-Computer Interaction (HCI) is a multi-disciplinary field focused on designing, evaluating, and implementing interactive computing systems for human use.
- HCI examines how humans and computers influence each other's behavior over time, particularly through the lens of human goals and tasks.
Key Concepts in HCI
- Usability: The measure of how effectively a system supports user tasks, emphasizing usefulness and ease of use.
- User-Centered Design: A design approach that prioritizes the needs, preferences, and behaviors of users throughout the development process.
Interconnected Fields in HCI
- Psychology and Cognitive Science: Investigate user perception, cognition, and problem-solving abilities.
- Ergonomics: Focuses on users' physical capabilities and interactions with systems.
- Sociology: Provides insights into the broader contextual factors influencing user interaction.
- Computer Science and Engineering: Responsible for the technical implementation of HCI systems (hardware and software).
- Business: Addresses market needs and user satisfaction to drive design choices.
- Graphic Design: Dedicated to creating effective and visually appealing interface presentations.
- Technical Writing: Ensures clarity in documentation, user manuals, and on-screen content.
Goals and Components of HCI
- The primary objective of HCI is to support users in accomplishing their tasks efficiently and effectively.
- This involves creating systems that are useful, usable, and regularly used by the intended audience.
HCI Components
-
Human Elements:
- Sensory systems include visual, auditory, haptic, and spatial modalities.
-
Computer Elements:
- Input peripherals consist of keyboards, mice, trackpads, touch surfaces, screens, microphones, and sensors for data input.
Interaction Models
- HCI encompasses multiple interaction models including Man-Machine Interaction (MMI) and Human-Machine Interaction (HMI), reflecting varied perspectives on user and system engagement.
