MCQs for HCI Course

What is Human-Computer Interaction (HCI)?

• The study of how computers communicate with each other

• The study of the interaction between people, computers, and tasks

• The process of designing only graphical user interfaces

• The use of artificial intelligence in computer systems

Why is it important to understand users in HCI?

• To make computers more expensive

• To take into account cognitive processes and limitations

• To ensure computers replace human decision-making

• To reduce the need for user testing

Which of the following is NOT a core cognitive aspect in HCI?

• Attention

• Perception and recognition

• Physical strength

• Memory

What is the 'User Interface' in HCI?

• Only the visual elements of a system

• Everything the user encounters, including layout, content, and navigation

• The internal code structure of an application

• The speed of the computer's processor

What are the three key aspects of a successful product in HCI?

• Useful, usable, used

• Speed, security, stability

• Design, function, price

• Accessibility, responsiveness, innovation

Which of the following senses is NOT a primary input-output channel for humans in HCI?

• Sight

• Hearing

• Touch

• Taste

What is the function of rods and cones in the eye?

• Rods detect color, and cones detect movement

• Rods detect movement, and cones detect sound

• Rods detect low light, and cones detect color

• Rods detect color, and cones detect brightness

What are the three components of color perception?

• Hue, intensity, saturation

• Brightness, contrast, texture

• Frequency, amplitude, timbre

• Light, shadow, reflection

What is an example of an optical illusion in HCI?

• A user mistyping a password

• A website loading slowly

• Perceiving an object's size as constant despite distance changes

• A touchscreen responding to multiple fingers

What is the difference between short-term memory (STM) and long-term memory (LTM)?

• STM stores information temporarily, while LTM stores information permanently

• STM has unlimited capacity, while LTM is limited

• LTM can only store numbers, while STM stores words

• LTM is always accurate, while STM is unreliable
