The Suomi project aims to reduce stress levels by transforming traditional spas into smart environments through the use of microcontrollers and machine learning. It incorporates user feedback and surveys to create a guide that enhances spa experiences and ensures user safety by providing tailored wellness suggestions based on individual health data. The project's architecture is built on Microsoft .NET and is designed to connect with IoT devices to improve user interaction and relaxation during spa visits.

3. INTRODUCTION
Idea and purposes explanation

4. PROBLEM AND SOLUTION
• 7 people die from stress every 2 seconds. What do anxiety, panic attacks,
depression, coronary heart disease, high blood pressure, fears, phobias, irritable
bowel, fibromyalgia, ulcers, self-destructive habits like overeating, and others all
have in common?
• They are all either caused by or made worse by STRESS! Our idea is to reduce
stress level. What is the best way to do this if not with a spa?

5. HEALTHY
• According to Bruce Becker, MD,
immersing yourself in water in
general up to your neck gives you
a cardiac workout
• Hot water promotes relaxation
which helps you sleep
• Mayo Clinic researcher Thomas
Allison PhD, did a study that
shows that sitting in a spa bath
can lower your blood pressure

6. SUOMI POWERED
• Many people in the spas and wellness centers do wrong journey and
are afraid to use some room
• SUOMI lets a spa owner to turn a spa into a smart one for BETTER
results, thanks to microcontrollers connected to a machine learning
software that will help spa’s users to make for them decisions about
wellness journey
• In order to understand that SUOMI was what people wanted, we made
a lot of questions to users

12. WHAT USERS WANT FROM A SPA

13. INTERVIEWS TO REAL USERS
We asked to friends, family members and others what do they think about a “smart
guide” that will help a spa customers to maximize its benefit and to avoid
dangerous practices
Giulia: “I think it is an awesome idea. When I go to a spa I
never know what to do and in what order, so I get annoyed
by these decision, while what I would like to do is simply
relax”.
Chiara: “What scares me about the wellness centers is
facing paths or journeys that could be harmful to my
health. I think someone should improve spas from this
point of view”.
Tina: “I never saw spa staffers
helping customers with their
experience from the start to the
end. They usually do a briefing to
everyone at the entrance, but after
that they don’t say to anybody what
is recommended to do after some
experience”.

14. SURVEYS RESULTS
SUOMI IDEAL USERS…
• Want spa and relax area services
• Don’t use often smart devices in a spa
• Want a guide that will help them to maximize the spa experience and to
avoid bad practices
SUOMI SHOULD OFFER…
• Spa and relax area services
• Usability for those who don’t use smartphone in a spa
• A smart and “hidden” guide that help customers to enjoy
the spa and to avoid a dangerous experience

16. CIRCUIT: STM32 NUCLEO-F401RE AND PULSE SENSOR SEN-11574
Nucleo-F401RE gathers heartbeat information via SEN-11574

17. CIRCUIT: STM32 NUCLEO-F401RE AND PULSE SENSOR SEN-11574
Red led is switched on: measurement is completed

18. HEART BEAT MEASUREMENT
STM32 Nucleo-F401RE gathers
heartbeat information via
Pulse Sensor SEN-11574 and
makes a calculation on the
average BPM
Later, BPM will be used by
SUOMI to give spa suggestions
to users to avoid bad practices
and maximize the experience

19. PROTOTYPING
Mockups and prototypes making and evaluating

20. MOCKUPS
A mockup provides part of the
functionality of a system and
enables testing of a design
Here’s shown how to login,
insert your data, book for a
service and enjoy the spa

21. PROTOTYPE: USER DATA

22. PROTOTYPE: NO TACHYCARDIA AND NORMAL WEIGHT
In normal conditions, SUOMI will let the user to book for all services

23. PROTOTYPE: TACHYCARDIA AND OVERWEIGHT
In bad conditions, SUOMI shows only recommended suggestions
