The design aims to influence medical students to apply sunscreen daily by placing a sunscreen pump next to an existing hand sanitizer pump in their classroom. Students would be reminded via whiteboard messages and encouraged to develop the habit by associating it with their existing habit of hand sanitizing. Their sunscreen application would be tracked via daily email surveys linked to a Google spreadsheet displaying live results on a Facebook group.

Gel up, ‘Screen up!
‘Screen up fo yo life!
A conceptual design by Aditi Mallick
and Shubha Bhat
Sunscreen Challenge
To influence 5+ people to apply sunscreen daily
Time Limit: 7 days

2. Gel up, ‘Screen up!
• Persuasive Purpose
o To create cycle behaviors by influencing
5+ people to apply sunscreen daily
• Industrial Design

3. User Description
• 1st year medical students
• Those who attend class in M112 9am-
12pm
• All go on lunch breaks 12-1pm (some
outdoors, some indoors)
• All interested in health promotion

4. Gel up, Screen up!
Storyboard
Class 9am, write reminder on
12pm, place sanitizing gel +
sunscreen pump at door
chalkboard next to PowerPoint
5pm, receive 3-question survey Responses enter into google
(name, date, did you wear sunscreen?) spreadsheet to track progress

5. Prototype of Gel up, ‘Screen
up!
Google spreadsheet inputs into live trend on Facebook Group

6. Features/Functionality
• Med students are reminded to put on
sunscreen before exiting class
• @ 5pm students receive email to click “yes”
or “no” about whether or not they applied
sunscreen
• Answer enters into google spreadsheet
• Spreadsheet creates live trend analysis on
facebook group.
• Students can view, comment and track
progress

7. Theoretical Justifications
• Med students are already in habit of o “Gel
up” as much as possible to prevent spread of
infection.
• Presence of hand sanitizer pump triggers gel
application
• Therefore presence of sunscreen pump can
be placed next to gel pump at exit
• Email is cheaper than text
• Simple yes/no form
• Spreadsheet easy to track

8. Results of User Testing
• User 1: “I like having the hand sanitizer next to the
sunscreen because I am used to gelling up and I
like having my hands clean before I touch my face.
However, I usually just pump the gel and let it dry
as I walk away. Now I have to wait for it to dry
before pumping the sunscreen so it takes a little
longer.”
o Solution: Because of the delay, have two stations so that
people don‟t have to wait.
• User 2: “Writing a reminder on the board, placing
the sunscreen by the door and watching others put
it on helps me remember. However, sometimes I
don‟t feel like I need it since I‟m inside all day.”
o Solution: In the the whiteboard announcement remind
people to put on sunscreen if they are

9. Results of User Testing
(cont’d)
• User 3: “The form is pretty simple and quick, but
there are times that I just don‟t get to check all my
email at the end of the day and miss it.”
o Solution: Inform group ahead of time of subject and time that
email will be sent, ask them to set an alarm for that time so
that they remember to look for the email.
• User 4: It would be nice to get some reward for
putting on sunscreen daily!
o Solution: Once student fills out form, have automated “Good
Job!” message if applied sunscreen or health consequence
message if did not.
• User 5: If I have to put my name down, I am inclined
to lie and say that I put on sunscreen
o Solution: Have monitoring system, public results so people
less likely to lie

10. Shortcomings of Design
• Med students don‟t have class on
Wed, Sat, Sun
• Not everyone comes every single day
• Sunscreen and hand sanitizer gel
might not be best combo
• Live trend analysis from Google
spreadsheet to Facebook group might
be difficult/not currently possible

11. Expansion - What else is
possible?
• Competition between med students for
longest/most consistent sunscreen streak
• Friends of students can view progress on
facebook and comment, encourage, give tips
• Have a Gmail Health Habits task bar (like the
current task bar) that can be checked off
each day but regenerated every day as well.
The checks automatically get tuned into a
tracker that can be shared with others via
Facebook, etc
• Reach other grad students and undergrads
• Form teams with friends and family

12. Next Steps in Design
Process
• Buy sunscreen pump and hand
sanitizer gel
• Get permission to place it in M112
• Write the reminder on the board at the
beginning of each class
• Create the email survey and google
spreadsheet
• Create facebook group and link it to
google spreadsheet

13. Summary
• “Gel up, „screen up!” aims to influence 5+ 1st
yr med students to apply sunscreen daily.
• Utilizes in class written reminders
• Associates habit with gelling up (which is
now an ingrained habit in med students)
• Strategically places gel by door and works
the peer pressure
• Uses technology to track progress and give
feedback
