Study Notes

Defined as the study of the interaction between people (users) and computers.
Encompasses design, evaluation, and implementation of interactive computing systems.
Involves multiple disciplines: computer science, engineering, psychology, social sciences, and design.

Usability is characterized by three criteria:
- Useful: Enables users to accomplish required tasks effectively.
- Usable: Allows users to perform tasks easily and naturally without errors.
- Used: Attracts users and is accepted within organizations.

Humans have limited capacity for information processing, affecting design implications.
Interactions with technology are complex and influenced by cognitive factors.

The interaction between users and computers involves input-output channels influenced by physical and perceptual limitations.
Users receive output from computers and provide input in a reciprocal process.

Introduced by Card, Moran, and Newell (1983).
Simplifies the understanding of human processing during interactions with computer systems.

Human (Analog I/O): Users interact using various sensory modalities.
Computer (Interface): The medium through which users interact with technology.

Vision: Primary source of information; integral to most interactions.
Hearing: Often underappreciated but still important for communication and feedback.
Touch (Haptic Perception): Significant for physical interaction, despite being secondary to sight and sound in many contexts.

Motor Control: Refers to how physical movement influences computer interaction.
Memory Types:
- Sensory Memory: Initial stage of memory capturing sensory information.
- Short-term Memory: Functions as a working memory for temporary information holding.
- Long-term Memory: Stores factual data, knowledge, and procedural rules for later retrieval.
