Willing and Able!
Skipping instead of scanning
Difficulty searching
Narrow field of view
Easily overwhelmed
Limited working memory
Prefer simple navigation
Skipping Instead of Scanning
• Read every word on the page
• Skip over entire chunks of dense text
– < 3 lines of text triggered skipping
– Numbers, %, big words triggered skipping
• Start clicking on links instead of reading
the content
• May land in the middle of the page
Users did read this
Users didn’t read this
Difficulty Searching
• Avoid searching
• Prefer to browse topics using an
alphabetical or topic list (even if the list
is long)
– Provide multiple ways to browse (by A-Z
and by topic)
– List topics under multiple categories
• Struggle with spelling when using the
search function
Narrow Field of View & Easily
• Focus on the center of the screen
• Content in right hand margin mistaken
for ads and/or ignored
• Rarely scroll
• Even content written in plain language
can look overwhelming
Limited Working Memory
• Information Overload – takes
concentration and effort to read the text on
the page
• Less likely to remember content from
previous pages and are rarely looking
ahead or back on a page
• Difficulty making the connection between
the results page and the data they entered
on the previous screen
Prefer Simple Navigation
• Unfamiliar with – and often ignore –
common navigational elements like dropdown menus and breadcrumbs
• Success with simple tabbed navigation
with linear (numbered) pages
• Need to be able to use the back button
