What is an assumption?
Taking something for granted when it needs further investigation.
What is a claim?
making a assertion or conclusion that may (or may not) still be open to question
Think about these when designing experiments:
1) Are there usability or user experience problems with an existing product? If so, what are they?
2) Are there problem statements supported by empirical data against goal requirements or are you making assumptions?
3) Why do you think these problems exis
Problem Space to Design Space
Having a good understanding of the problem space usability and user experience problem space - and goal requirement - can help inform the design space
Conceptual model
a high-level description of how a system is organized and operates
Interface metaphors
Are used to exploit familiar knowledge to help users understand the "unfamiliar
Interaction Types
Instructing
Conversing
Manipulating
Exploring
Interaction Type - Instructing
-Issuing commands and selecting options
-Users telling the system what to do
-Main benefit: quick and efficient interaction
Interaction Type - Conversing
-Interacting with the system as if having a conversation
-Pro: familiar interaction, more comfortable
-Con: misunderstanding being annoying, need for a backup
Interaction Type - Manipulating (moving things around)
-Interacting with objects in a virtual or physical space by manipulating them (selecting, dragging, opening, closing, zooming action on virtual objects)
-Pro: Can be picked up quickly, work fast to carry out multiple tasks, good memorability
-Cons: Not al
Interaction Type - Exploring (exploring an environment)
-moving through a virtual environment or a physical one (web browsing)
-can involve users moving through (and manipulating) virtual or physical environments
Interaction vs. Interfaces Types
Interaction type:
-what the user is doing when interacting with a system, e.g. instructing, conversing, manipulation, exploring
Interface type:
-the kind of interface used to implement a type of interaction; e.g., using a mouse vs. a touch screen for "ins
Paradigms
-general approach adopted by a community for carrying out practice or research and development (R&D)
-have shared assumptions, concepts, values, and procedures
