MODULE 3 Flashcards
Conceptualizing design:
Finishing vague ideas about proposed products in terms of feasibility, desirability, and usefulness
Assumption:
Taking something for granted when it requires more investigation
Claim:
Stating something to be true when it’s up for debate
Analyzing the problem space:
- What’re the problems of an existing design?
- What’re the reasons behind these problems?
- How will the proposed design solve these problems?
- How will the proposed design change the ways of doing things?
Benefits of conceptualizing:
- Orientation
- Open-minded
- Common ground
Conceptual model:
Description of how a system operates so designers can straighten out their thoughts
_____ provides a strategy and framework of concepts and their interrelations
Conceptual model
Components of a conceptual model:
- Specifying metaphors
- Understanding concepts
- Understanding relationship between concepts
Interface metaphors:
Interface designs that are similar to a physical entity
Pros of interface metaphors:
- Makes learning new systems easier
- Helps users understand the underlying conceptual model
- Innovative and accessible
Cons of interface metaphors:
- Breaks cultural rules
- Constrain designers
- Conflicts with design principles
- Forces users to understand the system only in metaphors
- Designers might use bad parts of bad existing designs
- Limits imagination
Interaction types:
- Instructing
- Conversing
- Manipulating
- Exploring
- Responding
Direct manipulation properties:
- Continuous representation
- Physical actions and button pressing
- Rapid reversible actions
Pros of direct manipulation:
- Easy to understand
- Carry tasks quickly
- Retain concepts
- Error messages rarely needed
- User confidence
Cons of direct manipulation:
- Metaphors can be considered literally
- Not all tasks can be described by objects
- Some tasks are better achieved through delegating
- Covers screen space
- Using a mouse can be a bit of a drag (pun intended)
