Human-computer interaction

Definition

Human-computer interaction (HCI) is the study and design of the interaction between people (users) and computers. It focuses on improving the usability and user experience of computer systems, ensuring that technology complements human capabilities and needs. HCI encompasses various disciplines, including computer science, cognitive psychology, design, and ergonomics, to create user-friendly interfaces and experiences.

5 Must Know Facts For Your Next Test

1. HCI aims to improve user satisfaction by focusing on designing technology that is easy to use and understand.
2. Ergonomics plays a critical role in HCI, as it helps in creating designs that accommodate human physical abilities and limitations.
3. The iterative design process is vital in HCI, as it involves prototyping, testing, and refining designs based on user feedback.
4. Cognitive psychology contributes to HCI by providing insights into how users think, learn, and remember information when interacting with computers.
5. HCI is essential for developing accessible technologies that cater to users with diverse abilities, ensuring inclusivity in design.

Review Questions

• How does ergonomics influence the design process in human-computer interaction?
  • Ergonomics significantly influences the design process in human-computer interaction by ensuring that computer systems are tailored to fit the physical and cognitive abilities of users. By considering factors such as body posture, hand positioning, and visual strain, designers can create interfaces that reduce discomfort and enhance usability. This focus on ergonomic principles helps improve overall user satisfaction and efficiency during interactions with technology.
• Evaluate the importance of user feedback in the iterative design process of human-computer interaction.
  • User feedback is crucial in the iterative design process of human-computer interaction because it provides insights into how real users interact with a system. By gathering feedback through testing prototypes, designers can identify pain points and areas for improvement. This continuous loop of testing and refining leads to more intuitive interfaces that better meet user needs, ultimately enhancing usability and user experience.
• Assess the role of cognitive psychology in shaping effective human-computer interactions and provide examples of its application.
  • Cognitive psychology plays a vital role in shaping effective human-computer interactions by offering insights into how users process information, learn new systems, and make decisions. Understanding cognitive load helps designers minimize unnecessary complexity in interfaces. For example, using clear labeling and intuitive navigation reduces confusion for users, while considering memory constraints allows for better organization of information. Such applications lead to more efficient interactions that align with how users think and behave.
