Study Notes
Overview of Human-Computer Interaction (HCI)
- HCI is a multidisciplinary field focused on the design, implementation, and evaluation of user interactions with computing devices.
- Initially emphasized computer interface design, now encompasses all forms of information technology.
- Increased importance as computers have become integral to everyday life.
Usability and User Experience
- High usability ensures interactions are efficient and meet criteria: correctness, efficiency, safety, utility, learning, and retention.
- User experience prioritizes overall user involvement, including satisfaction, enjoyment, motivation, and aesthetic appeal.
- Interaction involves how humans complete tasks via user interfaces, which include both software (e.g., displays on monitors) and hardware (e.g., keyboards, mice).
Importance of HCI
- Effective HCI enhances productivity across industries by improving interface usability.
- Poorly designed interfaces hinder user experience despite functional capabilities.
- Aesthetics and usability together are critical for commercial success, exemplified by Apple's attractive product designs.
- HCI has profoundly impacted computing history and transformed daily life interactions with technology.
Impacts of HCI
- Development of the spreadsheet interface revolutionized business computing.
- The internet's success is attributed to the web-browser interface.
- Widespread use of smartphones and mobile devices is a direct result of effective HCI.
- Emergence of body-based and action-oriented interfaces has enriched gaming experiences.
Principles of HCI
Know the User
- User-centered design focuses on catering to the specific needs and capabilities of target users.
- Essential information like gender, age, education, and computing experience is analyzed to tailor interactions and interfaces.
- Universality in usability aims to accommodate a diverse user base but poses challenges in multicultural contexts.
Understand the Task
- Understanding the task involves identifying the purposes users aim to achieve through the interactive system.
- Task analysis encompasses the sequence and structure of subtasks appropriately designed for user context.
- Examples include interaction modeling for website logins and conceptual system access models in organizations.
Conclusion
- HCI plays a vital role in shaping user interactions, improving productivity, and enhancing technology usability.
- Continuous adaptation and understanding of user needs and tasks are essential for effective system design.
