Users read what they need to read
12. Usability = “the extent
to which a product can
be used by specified
users to achieve
specified goals with
effectiveness,
efficiency, and
satisfaction in a
specified context of
use.” ISO 9241-11
@romanocog @richmondux
+ emotions and
perceptions = UX

UX Data
18. Traditional UX research is
good at explaining what
people say and do, not
what they think and feel.
@romanocog @richmondux
Why should we measure implicit?

*Satisfaction Questionnaire: Please rate how difficult it was to log in on this device. 1= not difficult at all to 5= extremely difficult.
“Love the picture in the middle of it.”
“It looks very clean and very simple.”
“It looks pretty organized, it's a nice design.”
When asked how they would save information,
four of six participants said they would
bookmark the page or take a screenshot of
the information. Only two mentioned that
they would use the site functionality to save
for later use.

26. Issue: Error messages are not useful.
26
UX Best Practice: Specifically explain the error, and place the messages near where the error
occurs so the user can quickly fix the error and move on.
• “How do I advance to the next screen?”
• “It seems like it's stuck on the screen.”
M
Gaze Plot: After getting an error message, the
participant had to search all over the screen to
find the missing field.
@romanocog @richmondux
28. Issue: The ‘Back’ button is not consistent.
28
UX Best Practice: Make the location of the ‘Next’ button consistent across all devices by placing it
in the lower right corner. This will assure users that their selections will be saved and promote a
sense of linear progression.
• “I was expecting ‘Next,’ but I
guess I have to push
‘Back.’”
• “It was hard to get
confidence that I was
proceeding in the right way.”
• “It didn't seem to flow, if you
will—you had to go back and
forth.”
@romanocog @richmondux
29. Issue: The location of ‘Next’ is not intuitive.

* Couper, M.P., Baker, R., & Mechling, J. (2011). Placement and Design of Navigation Buttons in Web Surveys. Survey Practice,
4(1).
• “Where and how you click is a bit counter-intuitive. [It’s] not super
obvious which button to click to get to next sections.”
• “I feel like the ‘Next’ should be at the bottom and not the top.”
UX Best Practice: Users expect consistency and for navigation buttons to be close to the last entry
field.* Place all ‘Next’ and navigation buttons near the last entry fields.
Intuitive ‘Next’ button location Non-intuitive ‘Next’ button location

30. Issue: The iPad website keyboard blocks the screen.
30
UX Best Practice: Design the layout of the page such that important functions are always visible
while the keyboard is open.

31. Issue: Workload is high when searching for entries.
31
UX Best Practice: Follow users’ mental model: Arrange previous entries with the most recent at the
top.
@romanocog @richmondux
32. Issue: Icons are not clickable and do not match user expectations.
32
• “I’m going to click on it, but it's not doing anything.
That is annoying.”
• “Do these not work?”
UX Best Practice: Reduce the amount of non-clickable real estate on the homepage. Focus on
making icons and images clickable. This will help the homepage feel more intuitive as users expect
icons and images to function as active links.
Logo should link to the homepage, similar to the way
logos work on websites.
Clicks along the bottom of the PC homepage showing that participants expected the icons to be working links.
Homepage on the iPad
website does not display
the clickable links below
each icon.

Assess the UX across devices
• Not necessarily the same UX across
all devices
• Different issues occur
• Match user expectations and product
objectives
• Conduct UX testing with real users
