Previous: Identifying Patterns
Having generated tentative patterns,
we sought to validate of these patterns.
With the initial pattern set we
examined the grouping and content of the patterns to validate:
The study involved three tests, described below. All of the tests were run on
twenty-nine (29) subjects.
The subjects were from a graduate class in interactive system design. The
experiment was run early in the course, before any discussion in the class of
patterns and generative user-engineering principles.
The subjects were part of one of
four sessions which lasted up to 90 minutes.
- that the defined patterns are more general than
the existing principles.
- that others would organize principles in similar
clusters, both with and without the aid of the defined patterns.
