|
- mental models are created by experience, metaphors, and analogical reasoning
|
|
- these models are developed further through interaction with the system
|
|
- designers (wrongly) often expect the users model to be the same as theirs
|
|
|
|
A mental model mistach leads to:
|
|
- slow performance
|
|
- errors
|
|
- frustration
|
|
|
|
[participant-observation](notes/participant-observation.md) appretiships (and other techniques such as [evaluating-designs](notes/evaluating-designs.md)) can uncover these mismatches.
