Human Computer Interface Unit 1

Which of the following is NOT typically considered an input-output channel for humans?

• Sight
• Sound
• Touch
• Telekinesis

What is the primary purpose of "Design Focus: Getting noticed" in the context of human input-output channels?

• To highlight advanced display technologies.
• To discuss how interfaces can effectively attract user attention.
• To explain the physiology of human perception.
• To describe methods for data compression.

The "Design Focus: Where's the middle?" likely pertains to which aspect of human perception?

• The ability to precisely locate objects in a 3D space.
• The challenge in designing interfaces that provide clear visual cues for alignment.
• The concept of human short-term memory capacity.
• The process of auditory localization.

What concept is explored in the "Design Focus: Cashing in"?

• The economics of software development.
• How human memory is utilized in everyday tasks, like remembering PINs.
• The financial benefits of good HCI design.
• The importance of user feedback.

The "Design Focus: 7±2 revisited" refers to a classic psychological theory related to:

• Long-term memory storage.
• The capacity of short-term memory.
• The range of human vision.
• The ideal number of menu items.

Human memory is often categorized into which main types?

• Active and Passive
• Explicit and Implicit
• Sensory, Short-term, and Long-term
• Visual and Auditory

Which cognitive process involves drawing conclusions from specific observations?

• Deduction
• Induction
• Abduction
• Heuristics

"Design Focus: Human error and false memories" likely discusses:

• How technology can correct human mistakes.
• The unreliability of human recall in certain situations.
• The development of AI systems that mimic human thought.
• The importance of robust error handling in software.

What role does emotion play in human-computer interaction?

• It is irrelevant to interface design.
• It primarily affects system performance.
• It can significantly influence user experience and task performance.
• It only impacts expert users.

Why are individual differences important in HCI design?

• To ensure all users have the same exact experience.
• To tailor interfaces to specific user groups and abilities.
• To standardize all user interactions.
• To reduce the complexity of the design process.
