Study Notes

Overview of Human-Computer Interaction (HCI)

HCI is a cross-disciplinary field involving theory, design, implementation, and evaluation of human-computer interactions.
Encompasses productivity, safety, and entertainment to optimize human-computer activities.
Initially focused on computer interface design; now extends to various forms of information technology.

Importance of HCI

Increasingly vital as computers integrate into daily life.
Emphasizes high usability and user experience, transcending mere functionality.
Usability criteria: correctness, efficiency, safety, utility, learning, and retention.
User experience aims to enrich overall engagement, prioritizing satisfaction, enjoyment, and aesthetics.
Effective HCI leads to higher productivity across industries; poor interfaces hinder user benefits.
Aesthetic appeal is critical for commercial success; hence, a user-friendly design is imperative.

Impact of HCI on Technology and Daily Life

Successful innovations stem from effective HCI applications.
The spreadsheet interface revolutionized business computing.
Web browsers facilitated the Internet phenomenon.
Rise of smartphones and mobile devices attributed to effective user interfaces.
Action-oriented interfaces enhance gaming experiences.

Principles of HCI

Know the User

User-centered design focuses on adapting interfaces to meet target user needs and capabilities.
Essential user data: gender, age, education level, and computing experience.
User profiling aids in determining interaction modes and interface designs.
Universal usability aims to cater to diverse user groups, ensuring humane interfaces, though challenging to implement.

Understand the Task

Task refers to jobs users aim to accomplish with computing systems.
Understanding tasks involves interaction modeling and user analysis.
This principle requires breaking down tasks into identifiable sequences and subtasks within a broader context.
Examples include developing interaction models for login processes and conceptual models for system access.

Conclusion

HCI is integral to enhancing user satisfaction and system effectiveness.
Ongoing refinement is essential as technology continues to evolve alongside user needs.
