Human Computer Interactions

What does the term "Human-Computer Interaction" (HCI) primarily focus on?

• The design of computer hardware

• The study of programming languages

• The interaction between humans and computers to achieve goals

• The development of software for artificial intelligence

Which of the following best describes the purpose of usability in HCI?

• To increase system complexity

• To measure the physical durability of devices

• To make systems easy to learn and efficient to use

• To test system security features

What is a key characteristic of user-centered design?

• Focuses only on system requirements

• Involves end-users throughout the design process

• Avoids feedback from users to save time

• Prioritizes aesthetics over functionality

What is an example of a "direct manipulation interface"?

• A command-line terminal

• A mouse-based drag-and-drop interface

• A text-based menu

• A voice command system

What is the purpose of creating "personas" in HCI?

• To simplify system code

• To reduce the number of system features

• To represent typical users and their needs

• To calculate the cost of system development

Which of these is an example of poor interface design?

• Clear labels for buttons and menus

• Consistent layouts across screens

• Icons with ambiguous meanings

• Intuitive navigation paths

What does the term "affordance" refer to in HCI?

• The cost of a system

• The actual and perceived properties of an object that determine its usage

• The energy consumption of a device

• The compatibility of software with hardware

What does Fitts’ Law predict in HCI?

• The likelihood of user errors

• The time required to move to a target area based on its size and distance

• The memory load on users while using a system

• The effectiveness of security measures in an interface

Why is "feedback" important in user interfaces?

• To reduce the system's speed

• To confirm the user’s actions and provide responses

• To restrict user access to certain features

• To increase the complexity of the system

What is the goal of usability testing?

• To identify system performance issues

• To measure how users interact with a system

• To develop programming languages

• To test the physical durability of hardware
