Study Notes

Human Information Processing (HIP) Model

Developed by Stuart Card, Tom Moran, and Allen Newell in 1983 to understand human cognitive processes.
Model comprises three main components: Attention, Memory, and Processors.

Components of the HIP Model

Memory includes Working Memory and Long-term Memory:
- Working Memory holds information temporarily for processing.
- Long-term Memory retains information over extended periods.
Processors consist of:
- Perception Processor: Senses and accepts external inputs, storing relevant parts in working memory.
- Cognitive Processor: Interprets inputs, consults long-term memory, and makes decisions based on the information.
- Motor Processor: Converts cognitive decisions into physical actions.

Attention in the Cognitive System

Attention is essential for facilitating and regulating cognitive functions.
Strong attention management helps reduce distractions and improves task performance.

User-Cognitive System Fit

High alignment between user mental models and system models lowers complexity and translation of goals to actions.

Perception and Representation Challenges

Difficulties in interpreting displays can arise from:
- Inconsistent color contrasts or optical illusions.
- Overly complex color schemes.
Graphics can serve two purposes:
- Modeling: Direct visual representation of concepts.
- Coding: Abstracted representation of ideas, such as quantitative data through charts.

Attention Limitations

Distractions affect focus; cues can help refocus efforts.
Complexity can lead to confusion; information should be structured logically to ensure clarity.
Clarity in interface states aids users in multitasking efficiently.

Memory Limitations

Short-term memory can typically manage 7±2 chunks of information; logical grouping aids memory retention.
Meaningful information enhances memorization; using effective icons and names is crucial to avoid arbitrary symbols.
Recognition is easier than recall; designs should favor recognizable structures like menus and icons.

Evolution of User Interface Development

Traditional software development emphasizes physical and interaction elements.
Usability engineering focuses on user tasks and requires continuous user involvement, adopting an iterative approach.
Good user interfaces vary in effectiveness; the challenge is to minimize malfunctions to adapt to users' needs.

Malfunctions and Usability Defects

Malfunctions occur when there's a mismatch between user expectations and system outputs.
Consequences include reduced usability and task completion obstacles.
Regular, lesser malfunctions are normal; systematic issues require resolutions for improvement.

Malfunction Analysis Framework

A disciplined methodology helps identify and resolve malfunctions.
Key analysis questions target: manifestation of the malfunction, interaction stage, user interface level, and root cause.

Types of Malfunctions

System-detected: Errors easily identified by automated checks (e.g., incorrect date formats).
User-detected: Issues noticed during operation, like confusing navigation paths.
Interaction style or element failures: General user difficulties with intuitive system operations.

Causes of Malfunctions

Lack of user motivation or attention can exacerbate issues.
Discrimination challenges and memory recall difficulties often hinder successful interactions.
External distractions, resource demands, and inadequate training contribute to malfunction occurrences.

Learning Difficulties

Learning and applying new systems can be frustrating, leading to misinterpretations or assumption of consistency based on past experiences.
Users might overlook directions or misinterpret training due to overload or vague guidance.

Goals of Human-Computer Interaction (HCI)

Aimed at enhancing safety, efficiency, and usability through:
- Improved visibility and feedback.
- Understanding affordances and user perceptions.
Productivity is determined by the interaction between functionality and usability.

Usability Factors and Engineering

Key usability factors include learnability, acceptability, and fit within user contexts.
Employ layered approaches to address user needs, ensuring frequent evaluation and adjustments.

Summary Insights

Understanding human cognitive limitations is critical for effective design.
Star models with iterative evaluations at their core represent best practices in usability engineering.
Recognizing malfunction as a usability defect emphasizes the need for continuous improvement based on user feedback and needs.
