Human-computer interaction (HCI) is the study of how people design, implement, and use computer systems and how computers affect the lives of the users. It focuses on making technology user-friendly and effective.
Key Characteristics / Core Concepts
- Usability: How easy and efficient a system is to use.
- User Experience (UX): The overall experience a user has with a system, encompassing usability, emotional response, and overall satisfaction.
- Accessibility: Designing systems that are usable by people with disabilities.
- User Interface (UI): The point of human-computer interaction, encompassing elements like screens, keyboards, and mice.
- Human Factors: Considering human capabilities and limitations in the design process.
How It Works / Its Function
HCI involves understanding user needs through research methods like user interviews and usability testing. Designers then create interfaces and systems that meet those needs, iteratively testing and refining the design based on user feedback.
Examples
- Designing a user-friendly mobile app.
- Creating an intuitive website navigation system.
- Developing a voice-activated assistant like Siri or Alexa.
Why is it Important? / Significance
Effective HCI leads to more usable and enjoyable technology. It also helps ensure accessibility for everyone and can improve productivity and efficiency. Poor HCI can lead to frustration, errors, and a negative user experience.
