3Usability Testing - Background
- Testing Objectives included
- Determine what information users are looking for
- Understand what tasks users expect to perform
-
- Gather initial impressions of the homepages
-
- Ensure labels and navigation are intuitive
-
- Identify missing information or features
-
- Locate, identify, and explore trouble spots to
understand and remedy them -
- Gather feedback and responses to validate design
strategy, process flow, intuitive level of
navigation, and level of content
4Usability Testing Methodology (How)
- Critical Mass and Usability Sciences developed a
set of tasks which users were directed to
complete - The tasks, created for both the NASA February
Launch site and PDR site, were designed to
compare common features and explore the key
components of the sites - The tasks were used as a guide for participants
to perform activities on the various areas of the
site and to provide feedback. - In addition to the standard tasks all users
performed, users visited specific areas of the
site depending on their audience definition - Participants maintained ongoing dialogue with the
Usability Analyst and voiced opinions regarding
the sites navigation, intuitiveness,
functionality, content, and specific usability
concerns.
5Usability Testing Audience (Who)
- Audience Experience/Interest
- Mix of users who had and had not previously
visited NASA.gov - Mix of interest level in NASA and space

8Usability Testing Findings
- Overall participants reported a positive
experience with both sites, although they favored
the PDR -
- PDR appeared to offer more information and
features -
- PDR organization and layout was easier for to
understand -
- Users liked the Sub-categories offered within
specific segment pages of PDR -
- Selectable grade levels in students navigation
helped understanding -
- PDR personalization was seen as valuable
-
- Users liked the larger font, use of color,
animation, and organization of the for Kids page
9Usability Testing Findings
- Flash Introduction Issues
-
- Most of the press media, educators, and general
public skipped the intro in order to quickly get
into the site -
- Almost all of the kids, middle school students
and high school students liked the intro video -
- Many users indicated that they did not have a
sense of how long the intro was -
- Several of the educators either overlooked the
visit the Educator Astronaut site link or were
unsure what it meant -
- Some users clicked the Visit the Educator
Astronaut site link, and were confused regarding
where they were and what they were viewing.
10Usability Testing Findings
- Flash Introduction Recommendations
-
- Reposition the intro as a multimedia feature on
Kids, Students, and Educator landing pages -
- Consider including it as a feature in the Flash
banner on the home page -
- Consider creating variations of this video that
are more audience specific -
- Consider adding a playhead or status bar to show
the duration of the video
11Usability Testing Findings
- Banner Issues
- Some users felt the graphics disappeared too
quickly - Users were unsure how to use the 1,2,3 options
- Banner Recommendation
- We are making the 1, 2, 3 larger and clickable
- The entire images will be clickable
- Animation speed may be slowed down
12Usability Testing Findings
- Labels / Navigation Headers Issues
- Users were unclear what some of the main
navigation labels meant - Labels / Navigation Headers Issues
- Revise labels where appropriate
- Make use of alt tags to provide some
descriptions where necessary
13Usability Testing Findings
- NASA Vision Bucket Issues
- On Feb Site - The titles Improve Life Here,
Extend Life to There, and Find Life Beyond
were confusing to several users - NASA Vision Bucket Recommendations
- When these users viewed the PDR site, they stated
that the titles for the three main topics were
more easily understood
14Usability Testing Findings
- Left / Sub Nav Issues
- Many users did not notice the gray sub-navigation
menus located on the left-hand side of the page - Some users were confused that they could not
click on the first link within the sub-navigation
menu. - Left / Sub Nav Recommendations
- We will address this on the redesign. Though it
is important for users to notice the navigation,
the priority still is the featured content on the
pages.
15Usability Testing Findings
- Features Issues
- Many of the users were disappointed by the
content of the featured article, as they felt
that the article stopped - A few users commented that they did not fully
understand all of the verbiage used within the
article - A few of the users stated that they did not like
the layout of the featured articles. They wanted
these articles to contain more graphics, and
appear less technical - One user commented that the articles required too
much unnecessary scrolling - Features Recommendations
- Provide related links to additional information
- Provide a glossary feature to understand the
meaning of some of the words used within the
article - Explore the feasibility of implementing a
page-break strategy
16Usability Testing Findings
- Search Issues
- Some users felt that articles were irrelevant
based on the keywords they searched on results
were too broad - Some users felt overwhelmed by the number of
results - Users were confused by the returned, hits,
and total counts displayed - Users felt there should be more options for
navigating search results pages beyond next and
previous - Local search
- Some users did not understand the local search
feature on the PDR - The sub-search feature was seen as highly useful
but not obvious to many users
17Usability Testing Findings
- Search Recommendations
- Add method of accessing pages which are several
pages in front or behind the current page - Scrutinize search UI in detail
- Local search
- Consider color and layout of sub-search in UI
design revisions
18Usability Testing Findings
- My NASA Issues
- Overall - High user interest
- Some users did not understand the OneNASA label
- The term Channel was unfamiliar and unclear to
a few users. - My NASA Recommendations
- Refine current strategy
- My OneNASA label changing to MyNASA
- Finalize user path and interaction strategy for
MyNASA - Currently exploring alternate label options to
address channel confusion
19Usability Testing Findings
- Content Requests / General Feedback Issues
- Users seem to want an easier way to find Mission
information in a more chronological fashion - A Press Media user mentioned that he expected
to find a listing of contacts - Many users noticed the NASA Fact presented
throughout the site, but expected more from it - One user (post secondary educator) suggested that
he would like to see more sophisticated topics - Include the department and email address for each
contact in the Media Contact area - Click on a NASA Fact to view a more detailed
facts section
20Usability Testing Next Steps
- Critical Mass to forward full usability testing
results as well as specific recommendations for
each result along to NASA - Critical Mass requests any NASA usability
comments be forwarded to CM by Friday EOD
21NASA Feedback Background
- NASA provided Critical Mass with some navigation,
content, and general UI design comments - CM reviewed these in parallel with usability
feedback
22NASA Feedback Findings
- Font size and color Issues
- The font sizes cannot be changed and are small -
probable 508 compliance issue - Gray type used for photo captions is not easily
read - Graphics that contain type need to be large
enough to be legible - Font size and color Recommendation
- 508 compliance is specifically addressed in the
Low Bandwidth version - Consider allowing fonts to be resizable
- Reconsider gray type, make it darker. Ensure that
photo credits are presented differently than
article content
23NASA Feedback Findings
- Site header Issues
- Gray banner across the top is neither visually
interesting or functional it is a waste of space - The bottom banner is a great space to add "get
back" or "Back to top" navigation - In looking at the affinity level one that is
presented, the gray seems rather dominant, could
this be variable? - Site header Recommendations
- Gray bar is intended to establishes the NASA
identity, allow for persistent search navigation,
and remain neutral enough that it doesnt compete
with featured content below - Back to top anchors are a good idea - it might
also be a recommendation to limit the length of
pages or introduce a page linking strategy
24NASA Feedback Findings
- Featured content Issues
- Content below the fold, though changing on a
daily basis may be devalued. i.e. New Features - Worthy, interesting topics not highlighted in the
Flash Banner will be effectively buried by the
layout - Colored backgrounds may call out key content
better - On each Landing page, make one of the feature
stories stand out more the others. Just link to
the rest.
25NASA Feedback Findings
- Featured content Recommendations
- User feedback confirmed that the UI design is
highly successful in meeting expectations - Content priority is determined by NASA with
consideration for user feedback. Since importance
varies by user, the audience segmentation is
prominent. Other high priority content is
included in the rotating banner, and the Search
feature. - Other features are positioned appropriately on
the home page based on priority, however not
everything can be highlighted in the UI or
nothing will stand out - On Secondary pages, prioritized content is
located at the top in the 2 feature promotional
banners. Images and related media will help make
the content more compelling
26NASA Feedback Findings
- Rotating Flash Banner issues
- The rotating image is difficult to use. Numbers
arent clickable. Numbers too small. - Recommendation
- As per usability recommendations, text will be
linkable, navigation numbers larger, and image
rotation could be slowed down
27NASA Feedback Findings
- Navigation Issues
- Bread Crumb navigation may help guide users
through content more easily - Navigation Recommendations
- When considering breadcrumb, we noted that
content is mainly limited to 3 levels (Home
Section Page Feature Article), or it is often
linked to a new new window after three levels. -
- When tested, users were able to determine where
they were within the site and how to get back to
previous pages -
- It was noted that many people prefer to use the
browser back button.
28NASA Feedback Findings
- Suggestion
- Make the large promo banner inside specific
sections be a rotating Flash promo (as on the
home page) - Recommendations
- Flash banners inside sections are a good way to
feature content. They could rotate features or
use flash to promote a single feature. - These will need to designed and constructed in a
way that is appropriate to the audience and
content as well as being considerate of the
forthcoming NASA.gov Design Standards. -
29NASA Feedback Findings
- Suggestions to UI Design
- Add more curves to the design. The site looks
very stark and hard. - Consider revising colors
- Recommendations
- Introducing another type of visual language to
the pages that contain a lot of information and
strong organizational structure would not assist
users in understanding the site - Colors chosen for the home page reflect the NASA
identity and also reference the American flag - Very positive user feedback and response to UI
design , any changes should be directed towards
addressing specific usability concerns or changes
in strategic direction
30NASA Feedback Findings
- Suggestion
- Upon entry into the secondary pages, there is
extreme NASA overload - Remove some of the features and news links.
Adding white space will give the site a cleaner
look and a more sophisticated appearance. - Recommendations
- There will be a lot of information in this site
as this is the nature of a portal - Information
is organized into features with short
descriptions that are easy to scan -
- User input suggested that more information is
beneficial as long as it can be understood
31NASA Feedback Findings
- Suggestion
-
- Create a consistent style for photo credits
- Make photo credits easier to read
- Recommendations
- Consider using a darker gray color or another
variation to existing style sheets - Ensure photo credits are separated from the main
article content
32NASA Feedback Next Steps
- Critical Mass to forward list of NASA commentary
to NASA along with associated recommendations - Critical Mass requests any follow up NASA
feedback be forwarded to CM by Friday EOD
33Information Architecture Review Background
34Information Architecture Review Recommendations
- Review of high level Information Architecture
document
35Information Architecture Review Next Steps
- Next Steps
- Review proposed structural feedback based on
results obtained in usability testing - Obtain feedback and confirmation that we can move
ahead with changes - Begin process of scrutinizing sub navigation
buckets - Finalize user interactions in MyNASA and
Search areas of nasa.gov - Apply changes to UI Design
