L3 Mental Models & Conceptual Designs Flashcards
(64 cards)
What are the learning outcomes of the lecture on Mental Models and Conceptual Design?
Understand what mental models are, conceptual models and design, how to apply them, and real-world examples.
What are cognitive frameworks in UE?
Internal (user reasoning) and external (interaction with systems and environments).
Define a conceptual model.
A designer’s high-level representation of how a system should behave and be understood.
What makes a conceptual model effective?
Clear metaphors, logical structure, accurate mappings, and consistent terminology.
What is the relationship between conceptual and mental models?
Designers create conceptual models to shape user-formed mental models.
What does conceptual design involve?
Structuring information, exploring alternatives, and selecting concepts aligned with mental models.
What tools support conceptual design?
Sketching, brainstorming, card sorting, semantic networks, flowcharts, scenarios, storyboards.
What’s excluded from conceptual models?
Presentation, implementation, screen and widget design.
What’s included in conceptual models?
Metaphors, objects, actions, user roles, mappings, interaction and interface types.
Why are metaphors important?
They build on user familiarity, helping users understand new systems.
How does mapping enhance usability?
Aligns design with user expectations and behaviors.
Define interaction vs. interface types.
Interaction = what users do; Interface = the medium of interaction.
What are four main interaction types?
Instructing, conversing, manipulating, exploring.
Give an example of instructing interaction.
Printing a file or saving a document.
List interface types.
GUI, speech, touch, tangible, haptic, mobile, command line, data visualization.
What are key brainstorming practices?
Be playful, nonjudgmental, write freely, reach for quantity.
What is card sorting?
A method to reveal user-driven groupings and organizational logic.
Card sorting advantages?
Fast, intuitive, reveals mental structures, supports early design.
Card sorting limitations?
Bound to predefined content, can be confusing with many categories.
What is a semantic network?
A visual web showing linked concepts and associations.
Pros and cons of semantic networks?
Pros: visual, intuitive. Cons: needs domain knowledge, may drift off-topic.
How are flowcharts used?
To map navigation, conditionals, and design logic visually.
What makes a flowchart effective?
Clear representation of user paths and decision points.
Purpose of scenarios?
Story-based depictions of user goals, settings, and behaviors.
