4. Introduction
 The functional assessment of aerobic endurance
is very expensive, time consuming and needs to
be done in specialized laboratories
 The evaluation is carried out by means of stress
testing and parameters such as heart rate,
electrocardiogram or maximal oxygen
consumption (VO2max) have been measured
 There are not any solutions yet, based on mobile
applications allowing people to perform this
assessment by themselves
LST – Life Supporting Technologies@2011 | WTHS’11– Gloria Cea Sánchez

5. Introduction
 Application objectives
o Propose an alternative solution to the current stress tests
o Promote personal self-care in people who often practice sports

7. Materials and Methods
Goal-Oriented Design Methodology
 The G-OD follows the trend of giving more
importance to the user in the process of
designing and developing interactive products
 It revolves around three fundamental aspects
o The characters  ‘Persona’ concept
o The scenarios: What should this product do? How should
this product come up and behave?
o The goals: are driving forces behind the behaviour
obtained from the user

8. Materials and Methods
AttrakDiff Questionnaire
 Based on a model by Hassenzahl and others
 Takes into account pragmatic and hedonic
aspects
o Pragmatic aspects: quality and usability
o Hedonic aspects: autonomy, security, competition
or relationships with others

10. Results
Functional Assessment System (FAS)
 The FAS is an AmI System developed for performing a
functional assessment of aerobic endurance
 Application automatically assumes many functions and is
more comfortable for the user
 To learn how to use the FAS almost perfectly, users do not
need a very high number of attemps

11. Results
User description: ‘Persona’
«My name is Laura and I am 29 years old. I
practice sports regularly, about 3 times a week.
For several years, I have been caring for my fitness
and my diet, so I would love to have some
information about my cardiovascular health at
any time, in a simple, convenient and reliable way.
I don´t like to go to a specialized place for a basic
control of physiological parameters during
exercise, because it is expensive and very time
consuming.»

19. Validation
 How do users react when using the application?
o AttrakDiff Questionnaire of Hassenzahl
o 11 users: 8 Men and 3 Women
o Age: 24-33 years
o Are familiar with technologies
such as Smartphones

21. Conclusions
 The FAS system has been validated using the
AttrakDiff questionnaire
 Very positive outcomes  the FAS has resulted to
be quite innovative, very intuitive and highly usable
 The application is expected to benefit people who
practice sports regularly by providing them with a
tool for completing functional assessment of the
aerobic endurance on their own
 It helps users to exercise in a healthier and safe way
