What is Human-Computer Interaction (HCI)?

• The process of designing computer hardware

• The process of designing interactive systems to support people in their everyday and working lives

• The process of designing software interfaces

• The process of designing video games

What is iterative design?

• A design approach that involves creating and testing multiple design variations

• A design approach that focuses on aesthetics in design

• A design approach that prioritizes speed in development

• A design approach that relies on user feedback only

What does the Usability-Learnability Framework represent?

• The relationship between a system's security and performance

• The relationship between a system's aesthetics and usability

• The relationship between a system's usability and its learnability

• The relationship between a system's hardware and software

What does efficiency measure in the context of Human-Computer Interaction?

• How fast a user can complete a task using a system

• How visually appealing a system's interface is

• How well a system meets the needs of its users

• How error-free a system is

What does effectiveness measure in the context of Human-Computer Interaction?

• How visually appealing a system's interface is

• How fast a user can complete a task using a system

• How well a system meets the needs of its users

• How error-free a system is

What does system specification involve?

• Creating a detailed description of a system's functionality, features, and components

• Testing a system's usability with real users

• Identifying and fixing usability problems in a system

• Evaluating a system's accessibility for people with disabilities

What is universal design?

• A design approach that focuses on aesthetics in design

• A design approach that prioritizes speed in development

• A design approach that involves designing systems that can be used by as many people as possible, regardless of their abilities

• A design approach that relies on user feedback only

What is usability testing?

• A method for identifying usability problems in a system by observing users as they perform tasks

• A method for evaluating a system's accessibility for people with disabilities

• A method for creating and testing multiple design variations

• A method for evaluating a system's performance and security

What is iterative redesign?

• The process of creating a detailed description of a system's functionality, features, and components

• The process of making changes to a system based on feedback from users and usability testing

• The process of testing a system's accessibility for people with disabilities

• The process of creating and testing multiple design variations

What is cognitive walkthrough?

• A method for evaluating a system's performance and security

• A method for creating and testing multiple design variations

• A method for identifying usability problems in a system by simulating users' thought processes

• A method for evaluating a system's accessibility for people with disabilities
