Walkthrough for the Web (CWW)
Tutorial (June, 2004)
The Cognitive Walkthrough
for the Web (CWW) transforms the original Cognitive Walkthrough (CW)
CWW bypasses the
CWW uses a slight adaptation of the four questions
Good fit with
website design processes. The web developer applies the CWW to one web
page at a time, the page under construction. The developer starts with
the home page and then moves to lower and lower levels of the hierarchy
(for example, home page, subsite main pages, intermediate level pages,
terminal node pages)
Capacity to model
representative goals for diverse user groups, including English-speaking
users with various levels of reading comprehension and background
knowledge. CWW has the potential to add new LSA semantic spaces,
and CWW will consequently gain the capacity to simulate users from
different cultures/subcultures and users who speak various languages.
Takes as input
long (100-word to 200-word) narrative goals that richly describe users'
understanding of their tasks and their underlying motivation
Built on a computer
simulation model of goal-driven exploration of websites the CoLiDeS
model. According to CoLiDeS, the user first parses the web page into
regions and focuses on the region that is semantically most similar
to the user goal. Then the user comprehends the actions available in
the focused-on region and selects the one that is semantically most
similar to the user goal. As a result, the heading labels for regions
play a crucial role in directing/misdirecting user attention, and an
important contribution of CWW is its ability to accurately identify
and repair problematic headings.
