Introduct ion
What is Paseo?
Paseo is a home training equipment that mimicsstepping in a natural way.
Paseo is part of a new business model that also engages people not willing to exercise in gyms by renting different equipment and guiding training via service system.
What was our task?Objectives of the study project
Background
The aim of the project was to look for new
solutions for personal training equipment for
ordinary people with their body, mind and space
in mind.
We were asked to address real life and real user
problems, finding so possibilities for sustainable
business ideas. As concepts these new solutions
should try to make a step further from current
solutions and products available on the market.
These steps further should stand either on the
new technological possibilities, addressing
formerly unnoticed new user groups and their
needs or new possibilities emerging from
changing habits, trends or value systems.
The purpose of the project was to learn
conceptual design approach starting from the
ideation phase and working out possible design
proposal.

“I learned how to share and exchange ideas - how to discuss them and defend them. Also, I learned to listen to people and to understand their way of thinking.”
“I learned about myself, how to work better in group. In addition to that, I learned that georgians regularly have live guitar connects in their dorm kitchen.”
“I learned how to form a concrete project from a very fuzzy starting point. How to narrow the possibilities and find a problem/project to solve.”
“ I learned not stop on one idea but generate a lot of them in a different directions. “
Process
Mapping the theme . . . Research & Insight
Sparta sports club was the place where project
launched and where our first lesson took place.
Argo Ader introduced us the world of gym and
we tried all equipment ourselves.
Liina Pääbo, a physiotherapist, was a secret
member of our team who guided us to make the
best for human body throughout the project.
Interviews with 10 people helped us to
understand different habits of physical activities
and its role in peoples daily life.
“Im not willing to go to gym with young guys who are in so good fit compared with me” Avtandil 52.
“Sports make me younger. Not just my body, but my mind too.”
Elena, 50
GIGA-mapping workshop helped us to
formulate our points of innovation. One week
workshop by Birger Sevaldson and Adrian
Paulsen.
Long way to the soluiton . . . Research & Insight
Secondly, speaking with friends and family, we
got to know that there are many people who
either forget their new year promises or give
away their sporting equipment already after few
weeks of buying one. Excitement about a training
equipment tends to last only for a couple of
weeks. Why not create a business model that is
based on the way how people actually tend to
behave?
Formulating the theme of the project
Theme of the project was opened and focus
was to be defined by ourselves. After three two
introductory weeks while we explored sports in
general we focused on two core topics.
Firstly, human body is designed for running and
in general, sporting should embrace the human
body. Exploring running as a type of sports, we
got to know the barefoot running trend. Also,
one don’t have to train only passing miles after
miles, but the muscle training of the right muscles
gives a basis for good results and balanced body. How could we support natural movement and
running natural?
How could we offer training equipment and perhaps training plan guidance to people willing to exercise in home?
Also there is a group of middle aged people who
would love to maintain their body, but they feel
uncomfortable lifting heights beside young and
fit guys in the gym. Also, its very common for the
mothers who have little babies, that they wish to
to lose wight, but can’t leave child alone.
Long way to the soluiton . . .
Process
PASEO (pa·se·o)
Meaning in English:A slow, easy stroll or walk outdoors.
[Spanish, from pasear, to take a stroll, frequentative of pasar, to go, pass; see pase.]
Process
What are the trends of tomorrow . . . Research & Insight
Barefoot running
The structure of the lower leg is very efficient
at absorbing the shock of landing and turning
the energy of the fall into forward motion,
through the springing action of the foot’s natural
arch. Running with sport shoes neglects the leg
natural ability. There is a new trend starting in
shoe industry to offer running footwear with thin
rubber sole, such as Vibram five fingers sandals.
Simplicity
Target group of Paseo is not the young hipsters,
but there is something to learn from the fixie
bike trend – the simplification. A casual biker
don’t need 21 gears, but needs a ride. Why to
make people decide and choose, while what
they actually look forward is an experience and
expression?
Trying out machinery in Sparta gym and in TUT
gym we were faced with tens of buttons and
options to choose from on the control panels.
Asking the gym facilitator and gymnastics coach
what all the options are good for, she told she
uses only two of them. Marketing competition
has led adding to new product a new feature and
result of it too many not useful features which can
confuse not professional user. Too many features
its frustrating, making people to choose. But
what the person actually wants is just to exercise,
and not to deal with another decision making.
The plain function what user actually wants, is a
needle to find from the pile of the features.
Smart grid
ICT enables more personal services, both in
monitoring as well as in pricing. Health care sector
is implementing personal monitoring and it will
go mainstream expcedtly in 5-10 years. Personal
monitoring also enables progressive, graded
health care taxing. As sporting lowers health
risks, monitored sporting activities might become
one of the components of your personal health
insurance - social tax rate.
Privacy respectful web 3.0
What goes up to the web, stays in web. A
modern force majore that people is becoming
more conscious. What and how to share
is a question, because the levels of public
transparency that people wish to show in the
social networks and in web is different. Current
product service systems are rich in the data and
promoted to be shared in detail also in social
circles. If the market of sport monitoring services
expands, new market segments, niche segments
will appear to offer experience oriented sports
Sharing economy
Bike sharing or Car sharing, Airbnb or
Couchsurfing and Kickstarter for financing –
thanks to the social web, it is possible to share
anything with anyone anywhere in the world.
Across the U.S., Canada, and Western Europe
people use car only 8% of the potential time,
Which means that over 90% of the time, car
costs people a lot of money and after is just sitting
around. Compared with cars the newly purchased
sporting equipment usage describes over the
period. In addition to economical reasoning,
sharing economy has been long subject in
sustainability movement and a tool in urban
planning to strengthen liaisons in communities.
Exploring and trying out the existingResearch & Insight
TUT gym
Our first research point was TUT gym, where we
had opportunity to try different equipment for
the feet muscles. Aino Voltri, a sport trainer, led
us from one device to the other showing what is
the right movements and what parts of muscles
are training. We took a lot of videos and photos to
have visual understanding of the process.
The objects of our interest in gym were stepping,
running equipment. As an observation we came
to conclusion that all of them effective but have
few minuses which is size and outlook spatially
the elliptical stepper. For people who does
not have much time on going to the gym it’s
would be not the best choose to have one of this
devices at home. Take too much place and look
a bit aggressively. Putting on first place comfort
we got first criteria for ourselves to make it
maximally effective but looking friendly.
The artificial surfaces like concrete or asphalt
was much more unpleasant and even painful.
Human body
Muscles intended to train
‒ m. peroneus longus
‒ m. tibialis posterior
‒ m. triceps surae
Needed movement
‒ put foot down front/middle part first
‒ unstable foot placement for training
‒ proprioception sense and balance
Study of running
We examined running in different surfaces
with and without sport shoes. The results were
surprising. Both of examiners tend to put heel
part of foot first. Even when running without
shoes.
It felt like with a sport shoes running was easier
and better, However Most shod runners -- heel-
strike, experiencing a very large and sudden
collision . People who run barefoot, however,
tend to land with a springy step towards the
middle or front of the foot. “Heel-striking was
painful when barefoot or in minimal shoes
because it causes a large collisional force each
time a foot lands on the ground.” - Tinatin.
So after few experiments we started to avoid
heel-striking and naturally started to put middle
part first. As result it was a bit harder to run and
we felt more muscles working.
Also while changing surfaces we convinced
that running in nature on the ground is best
experience, especially when running barefoot.
The surface is more soft and comfortable.

Solut ion
Paseo is a home training equipment that mimics
stepping in a natural way. Paseo is a part of a new
business model that also engages people, who
are not willing to exercise in gyms, by renting
different equipment and guiding training via
service system. Product is targeted to female/
male over age 30 (40).
The pneumatic stepper-like product has good
effect on lower leg muscles, developing also
balance. Paseo is good for the people recovering
from ankle injuries (for the people who had ankle
injuries).
Technical description
Paseo enables people who use it make
adjustments in the step height they want to train
with. Therefore people can choose the training
speed and level according to their needs. The step
height is regulated by the valve size. When the
valve cross-section is regulated down, it enables
people to train with lower pace or in high pace
but using only the small step height, as the air
exchange rate in pedals is very slow. When the
valve is open, people can train with higher step
size and therefore increase their training load,
as the air exchange rate is high. The following
approximations are made using an average step
speed and are therefore only for the purpose of
observation, how the equipment should work
Materials
The cover material is made of Flexible Plymer
Foam (MD) and the inflated peddals are of
plastizised polyvinylcholride. The material of the
frame is Acrylonile butadiene styrene (ABS).

A product service system Solution of the Product
Paseo service system is for the people who don’t
have time to go to the gym, who would like to
work out at home or office and who would need
extra motivation to do it every day.
Via Paseo service system it’s possible to rent sport
equipment. This solution will prevent customers
from purchasing not needed devices. Each user
will have profile, where it would be possible to
give feed back for the device, ask advice from a
trainer, find people on the same level.
Before ordering device each customer should
choose his/her level of exercise in a form of a
sport character:
Office worker ‒ Not physically active, the only
training for him/her is walking from bus stop to the
office. Busy lifestyle. ( Plan: 20 min each exercice
per each next day on Paseo with lowest intensively)
Dog walker ‒ person who is not sporty and not
physically strong. One that prefers to walk a bit
on the fresh air. (people who like passive style of
life, short distance walking and spend a evenings
outside or taking morning walks. Plan: 20 min each
next day with middle intensity)
City biker ‒ person using a bike to go to work, to
grocery, to university. Prefers to take a walk not a
car.(people with dynamic life style and have active
hobbies. Plan: 20 each next day min intensively)
Marathon runner ‒ person joining marathons
and active sports, he/she enjoy all the sports and
is physically strong. (people who are very into
training and take part in sport competitions. Plan: 35
min each day intensively)
Aerobics addicted ‒ a person who likes all the
aerobics and tried them all : body combat, Yoga,
Pilates, Latin dances etc. (somebody who can’t
imagine themselves without sport and need
to exercise every day. Plan: 40 min each day
intensively)
Dependently on the level the system generates
training plan for the month. After the 4 weeks of
practiceing on one device is done, one can order
new device on the internet and get it from the
smart box the next day. This is much more easer
then going to the shop or waiting long time for
the delivery.

How user understands and communicatesInteraction
Iinteraction
We went thought the different ideas, from
complex with many functions to most simple
versions. Combination of simple outlook but
smart device seemed to be most optimal.
Aim of the interaction and the service system is to
help the user stay motivated and train every day.
As light is very much associated with movement,
especially if it’s dynamic, we found it best
medium for the interface. The logic chain of
concept which we took for our interaction:
Green - Color - Visual perception - Visible Light - Energy
Technical solution
Our technical solution it’s production energy
from movement. In this way any mechanical work
transferring into electrical.
The piezoelectric effect converts mechanical
strain into electric current or voltage. All we need
for it - its energy source, circuit, storage for the
power and voltage regulator.
With this technology location of use does not
have any matter. Also, there is no need to change
batteries or hardwire power, and can work long
without maintenance.
Parts of the system:
‒ Piezo element
‒ Energy storage
‒ Voltage regulator
‒ Rectifier Circuit
A piezoelectric sensor is a device that uses
the piezoelectric effect to measure pressure,
acceleration, strain or force by converting them to
an electrical charge.

Graphics and Intearactive surfaceInteraction & Business model
Smart Textile
The upper surface of the product, is made of
Smart textile and it displays feedback using the
movement energy. It’s material which can react
on electricity, noise, temperature, pressure,
stress or load. And reflect it on the surface of the
material.
Smart textile interacts with the environment and
as our idea is to create a training equipment that
its less machine-like and instead communicates
with user in a more natural way.
To build up a smart textile system we need:
- sensing ( stepping),
- powering (was described in technical part of
interaction),
-communicating,
- data processing (micro processor).
As a material suitable for this purpose was chosen
lycra fabric coated with carbon-loaded rubber and
a commercial electro-conductive yarn.
Smart textile need a brain to work, a good way to
do that with Arduino (open-source single-board
microcontroller), and program can be written on
Wiring-based language similar to C++.

Approximation of the volume of the inflated pedal
In Paseo, the pedals are inflated with air and the
shape can be seen from Sele 1.
For the simplification of calculations, it is
presumed that the shape of the pedals is
approximately equal to a sphere, where segments
are cut out from the upper and lower part. For
estimating the volume integration is performed,
as shown on Sele 2.
V0 – volume
f(x) – line function
a- Starting point of integration
b- Endpoint of integration
Circle equation:
x0, y0 – centre point coordinates
r – radius of the circle
y
xO(0;0)
Sele 1
Sele 2
In our case:
x0=0 y0=0 r= 95 mm
Therefore:
The height of the pedal is h=75 mm, and assuming
that the cut out segments are of the same size, we
get
a = - 37,5 b = 37,5
Therefore, the volume is:
With this method it is possible to know the
volume of the pedal at every moment while
training with the equipment and therefore get
to know the amount of air moving through the
valve.
Based on the measurements for the step speed,
when walking on the stairs, the average time, the
foot moves from the uppermost position to the
down most position is :
t = 0,83 s
The absolute pressure in the pedals is
p = 141 855 Pa
Finding the air molecule root mean
square velocity
Solut ion
Engineering Design
R- Gas constant
T- absolute temperature [K]in our case T=295 K
-molar mass of air
vrk- mean square velocity
Now it is possible to calculate the valve cross-
section size. The maximum cross-section is when
the person wants to use the maximum step height
and therefore needs the fastest airflow.
When taking the starting of the observation at the
point when one foot is completely on the ground
and the other one in the highest position, the
amount of air moving through the valve while the
upper foot is going to the down most position is
2 times the amount of air in one pedal in the non
training condition. So the flow speed is estimated
to
The cross-section can be found with the
formulas:
Vv- volume of the air going through a valve
Sp-cross-section of the valve
S-distance to where the air molecule can move in
0,83 seconds.
t- Time for one step
So from previous we get:
With circle cross-section, the valve diameter
can be found:
d=3.6 mm
In Sele3, the graphic explains how big air flow is
needed for each step height.
n Sele 4, the graphic explains how big the valve
cross-section should be for the corresponding
step height.
All the presented data is estimated and when
actually putting together the step height
regulating graph, the calculations here should be
replaced with test results, carried on a working
prototype, as the material and its exact properties
will affect the results obtained.
