Questions?

3. INITIAL CONCEPT
● Medical alert system utilizing multiple sensors to
connect with designated emergency contacts when
vitals go out of range
● Would learn your patterns based on activity, user
entered data, and biometrics to make better health
decisions next time you repeat an activity
Basic health monitoring during fitness activities with a
contingency plan in place

4. RESEARCH
Competitive Analysis
Survey
Use Cases
Card Sort

5. COMPETITIVE ANALYSIS
●
●
●
●
●
Fitness Apps/Devices
Emergency Apps
Learning/Behavioral Apps
Location/Tracking Services
Biometrics and Sensors

6. SURVEY
● Sent to potential future users of the Red++ App
● 37 respondents
● 69% female and 31% male ranging in age from 18 to
over 55, with over half of respondents (69%) between
the ages of 18 and 35
● Respondents were asked to estimate the number of
hours per week spent doing physical activity, and
perceived level of exertion (low, medium or high
intensity).

7. SURVEY RESULTS
● Respondents wore a variety of health/fitness devices
and used a variety of health/fitness apps
● 69% analyze data from activities either sometimes or
always and 56% said that real-time data had high
importance to their overall experience.
● Hydration/water intake levels (74%),
sodium/electrolyte levels (66%), and heart rate (88%)
were important during or after an activity
● 72% want to notify EMS, 67% friends or family

8. USE CASE: NOVICE
●
●
●
●
Just starting to actively monitor his/her health when performing
activities
May not be ready to jump headfirst into regular monitoring, but are
interested in trying to maintain a record
May not know what is important to monitor or when his/her body is
reaching its limits
Red++ will help them learn not only their own limitations, but also how
their body is adjusting with regular activity

9. USE CASE: INTERMEDIATE
●
This user has generally mastered the basic features and is interested in
exploring more advanced features

10. USE CASE: ADVANCED
●
●
●
This user is very active and healthy
He or she could be a cyclist who has used several fitness apps and
devices
Convenient access to real time data is important along with a history of
activity

11. USE CASE: SOS (Significantly Out-of-Shape)
●
●
●
Similar to the novice in his/her inexperience with health-monitoring
fitness devices
The SOS user has purchased the app as a preventative measure to
dangerous overexertion
Easy set up is important

12. CARD SORT
55% of participants sorted the
cards into 7 similar groupings.
Actions:
●
●
●
●
Relabeled primary
navigation
Reorganized initial site
map
Added a
“History/Previous
Workouts” section
Separated the user
settings, to be called “”
Profile/Personal Info”,
and the system settings

19. LOW-FI PROTOTYPE

20. LOW-FI PROTOTYPE

21. USER TESTING RESULTS (LOW-FI)
●
●
Users confused by the overly complex
user login functions
Attaching sensors to specific activities was
difficult for users to execute

22. NEXT STEPS
●
●
●
Simplified Login
Tree-Sort Exercise
Site Map Structure Change

23. TREE-SORT
●
●
Distributed to 10 participants
Specifically wanted to determine the path
users would take to get to “Emergency
Contact” and “Heart Rate Pairing” screens.

24. TREE-SORT RESULTS
●
●
Overall success rate of 80-90%
Took approximately 10 seconds to complete each task
○ Task #1: Turn off notifying your emergency contacts when you go
for a workout
○ Task #2: Pair your heart rate monitor to the app
○ Task #3: Start a workout then view your workout summary
Actions:
● Place the app’s emergency notification feature under “Emergency
Contacts”
● Place sensor pairing under “Profile”

25. UPDATED SITE MAP

26. HIGH-FI PROTOTYPE

27. USER TESTING RESULTS (HIGH-FI)
●
●
●
●
●
No problems navigating to the profile page to change personal
information
Starting a new activity, clearing an alarm, and ending the activity simple
for all users
Confusion with red icon in the sensor menu, some thought it meant the
sensor was not paired, while others realized it was intended to remove
a sensor (unpair) from the current activity
Icon preferences showed that the majority of users liked the flat grey
icons the best
Post test survey questions averaged a score of over 4 in all areas with
questions ranging from app ease of use to attractiveness

28. CHANGES MADE
● Graphic changed for removing sensors
● Link to welcome screen added to "Red++" logo in
navigation bar
● Icons throughout changed to be consistent
● Hamburger on main menu to function as a back
button, rather than a return to welcome screen

29. FINAL DESIGN

30. LESSONS LEARNED
If we had better defined the features and purpose of the
app from its initial conception, could have saved time
that was spent reassessing the site map multiple times
and doing additional testing after initial prototype testing

31. FUTURE ITERATIONS (OR WHAT WE DIDN’T GET TO)
● Feature that allows users to take a health assessment
when they first begin using the app
● Expand the emergency alert system by sending
relevant information such as medical history, allergy
data, and insurance information to EMS and
emergency contacts
