Human-Computer Interaction and User Experience

Flashcards covering key concepts from Human-Computer Interaction and User Experience lecture notes.

What is the importance of User Interface (UI) design?

Good UI design enhances user experience, making applications more intuitive, efficient, and enjoyable.

What are the characteristics of a Graphical User Interface (GUI)?

GUIs use graphical elements like icons, windows, and buttons to allow users to interact with computer applications easily.

Define Human-Computer Interaction (HCI).

The study and design of user interfaces that facilitate seamless interaction between humans and computers.

What are the main input methods in HCI?

Users interact with computers using devices like keyboards, mice, touchscreens, and voice recognition.

How does Cognitive Psychology apply to UX design?

Cognitive psychology helps designers understand mental processes, improving how users interact and engage with interfaces.

Describe the concept of Cognitive Load in UX design.

Cognitive Load refers to the mental effort required to process information; UX designs should minimize unnecessary cognitive load.

What is User-Centered Design (UCD)?

A design approach prioritizing the needs, preferences, and feedback of users throughout the entire design process.

Explain the significance of feedback in user interfaces.

Feedback provides users with information about the outcome of their actions, enhancing understanding and confidence in using the system.

What are the three types of Cognitive Load?

Intrinsic Load (task complexity), Extraneous Load (unnecessary distractions), and Germane Load (effective mental effort for learning).

Name two types of memory in long-term storage.

Episodic memory (specific events) and Semantic memory (general world knowledge).

What advantages do Direct Manipulation interfaces provide?

They allow users to control UI elements directly, making interactions more intuitive and reducing error rates.

List some interaction styles in HCI.

Command line, menu selection, form-fill, direct manipulation, and gestural interaction.

Why is it essential to understand business junctions in HCI?

Understanding business junctions allows designers to anticipate challenges and align software design with user needs.

Define Multimodal interactions.

Interactions that involve multiple input and output methods, such as combining touch and voice for enhanced user experience.

What is the role of sensors in user interaction?

Sensors detect various physical phenomena (such as motion, temperature, and light) to facilitate more intuitive interactions.

Give an example of how emotional design influences user experience.

Designing interfaces that evoke positive emotions can build stronger connections between users and products, enhancing overall satisfaction.

What is the significance of accessibility in HCI?

Accessibility ensures that interfaces are usable by individuals with varying abilities, fostering inclusivity and equality.

Explain the concept of Interaction Styles.

Interaction styles refer to different methods by which users can engage and communicate with computer systems.
