What is Human-Computer Interaction (HCI)?

• The process of building physical computer components

• The study of how people interact with computers and digital systems

• A method of designing only mobile applications

• A programming language for user interfaces

• The study of how humans interact with other humans

Why is User-Centered Design (UCD) important in HCI?

• It ensures that systems are designed to meet the needs and expectations of users

• It eliminates the need for usability testing

• It focuses on hardware performance

• It only applies to websites, not software applications

• It prioritizes developer preferences over user needs

Which of the following is an example of an interaction model?

• Data encryption

• Direct manipulation

• Machine learning.

• Cloud computing

• Cybersecurity

What is an example of a direct manipulation interface?

• Dragging and dropping files on a desktop

• Writing a program in Python

• Running a background process

• Using a command-line script

• Typing commands into a terminal

What does usability in HCI refer to?

• The programming language used to develop a system

• The complexity of software development

• The system's ability to process large amounts of data

• The ease with which users can learn and efficiently use a system

• How secure a system is

Which usability principle ensures that users receive clear information about system actions?

• Feedback

• User privacy

• Error prevention

• Consistency

• Minimalist design

What is an essential element of a good user experience (UX)?

• Using only text-based interfaces

• High processing power

• Minimal security measures

• Complex navigation

• Intuitive and user-friendly design

What is the main purpose of usability testing in HCI?

• To reduce the cost of development

• To evaluate the performance of hardware components

• To assess how easily users can interact with a system

• To increase the number of features in software

• To eliminate all software bugs

Which of the following is a key trend in HCI?

• Limiting user feedback collection

• Reducing accessibility in digital products

• Removing graphical user interfaces

• Increasing the use of voice and gesture-based interfaces

• Avoiding personalization in software

How can HCI impact user satisfaction?

• By removing all visual elements from the interface

• By increasing loading times

• By prioritizing developer convenience over user needs

• By creating intuitive and efficient interfaces that improve user engagement

• By making systems harder to use
