Human-Computer Interaction Concepts

The video explores the intersection of psychology and computer science, focusing on human-computer interaction. It discusses usability, cognition, and interface design, emphasizing the importance of understanding human perception and memory. The video also covers affordances, recognition vs recall, affective computing, and emotional intelligence. It examines computer-mediated communication, mutual gaze, and human-robot interaction, including the uncanny valley. Ethical considerations in design are highlighted, stressing the need for responsible content curation and user interaction.

Why is it important to understand both human and computer strengths and weaknesses when designing systems?

• To increase the cost of system development

• To make systems less efficient

• To ensure systems are useful, usable, and enjoyable

• To make systems more complex

What is usability in the context of human-computer interaction?

• The degree to which a system is complex

• The degree to which a system can be used effectively and efficiently

• The degree to which a system is visually appealing

• The degree to which a system is expensive

Why is color intensity a good choice for displaying continuous data?

• Because it is easy to implement

• Because it is visually appealing

• Because humans are good at ordering intensities of colors

• Because it uses less memory

What is chunking in the context of human cognition?

• Grouping items into small, meaningful groups

• Ignoring irrelevant items

• Breaking items into individual pieces

• Combining items into one large group

What is an affordance in interface design?

• A feature that makes a system more expensive

• A feature that provides clues to the operations of things

• A feature that makes a system more complex

• A feature that makes a system less efficient

Why are icons used in interfaces?

• To reduce the cost of development

• To increase the complexity of the interface

• To trigger human memory through sensory cues

• To make the interface look colorful

What is affective computing?

• Computing that focuses on efficiency

• Computing that reduces system costs

• Computing that adapts to users' emotional states

• Computing that increases system complexity

What is computer-mediated communication (CMC)?

• Communication that occurs face-to-face

• Communication that occurs through handwritten letters

• Communication that occurs through computer systems

• Communication that occurs through telepathy

What is mutual gaze and why is it important?

• Looking away from others while talking; it boosts engagement

• Looking at others while talking; it boosts engagement

• Looking at a screen while talking; it reduces engagement

• Looking at the floor while talking; it reduces engagement

What is the uncanny valley in the context of human-robot interaction?

• A point where robots look completely human

• A point where robots look almost human but elicit an eerie feeling

• A point where robots look like machines

• A point where robots are completely non-functional
