Projeto desenvolvido para processo de seleção de estágio no INdt. Trata-se da criação de um aplicativo que ajuda no controle de peso. Neste projeto contém brevemente todas as etapas realizadas até a criação de suas interfaces gráficas.

1. Weight List
Interaction Designer Evaluation Test - INdt
Designer:Barbara Martins Nicolau

2. The Process
1º Similar Research
I researched the applications of weight control that exist in
the market, what are their definitions, interfaces, features,
functions and the feedback of people who are using or have
used any of these apps. There were four applications ana-
lyzed: The iHealth iOS platform; Bluetooth weight scale for
android; btScale and Simple Weight Recorder, both also on
the android platform. All applications mentioned are very
simple and with very direct interfaces, however I could see
and evaluate how well the Bluetooth Scale works as the app
receives and stores the data.

3. The Process
2º Enterview
All product design, must be centered on the user. The design-
er must understand their users, knowing their tastes, their
needs and desires. With that in mind I drafted 10 open ques-
tions: How often and where do you weigh? Do you usually
control your weight? What would help you control your
weight? Do You feel good about your body? Among other
questions, then put all the questions in a google doc form
and made it available at the Facebook. There was an immedi-
ate return of at least 20 responses. As I analyzed all the an-
swers I noticed that most people who do not attend a gym,
are usually weighing just a few times a month and are usual-
ly doing in a drugstore, in contrast if people who exercise reg-
ularly, they tend to weigh at least 3 times a week. Not a
single user know or are using applications of weight control,
but would like to use one that could compare current weight
with the previous weight and find their icm. Furthermore,
60% of the people want more interaction on the weigh time
and 50% feel better with your body when they are praised.

4. The Process
3º Interection with wii fit
Aiming to observe the interaction of people of different ages
with the wii balance, I asked four people to do a physical as-
sessment of the wii fit. Líbia 40 years had so much fun with
the wii technology and applications and had no problem in
understanding the exercises. Rodrigo 16 years, on the other
hand, presented some impatience with the various screens
conversation and feedback that were appearing between ex-
ercises. Rui 60 years, had much difficulty in understand the
exercise and did not find the data given correct. Gadi 80
years, was guided by me and although she felt some difficul-
ty, seemed to have so much fun with all the screens and their
results. All these experience has given me, many ideas to
build the project.
4º Brainstorm
Time to put all the ideas in post-it.

5. The Process
5º Concept
What will my app do?
Help the users to control their weight, in a practical and safe
way.
Functions:
Receive recent measurements
Show measurements history
Set goals
Show notifications
Who is my app for?
For any user who want or need to control your weight.
How does my app fit in?
Samsung Galaxy S3
Where and when will my app be used?
In any environment that has a Bluetooth scale compatible
with the app. At any time of day, preferably early in the day.
What kind of content will I display?
Profile, Graphics, goals, interactions interfaces.
How can my app use the hardware?
Bluetooth, smart alert, memory.

6. The Process
6º Structure
So with everything in mind, I set up the structure,
the flowchart of screens, of how the application will
work, and the application navigation screens.

7. The Process
7º Sketch-up
After all the structure in place, I started drawing the screens
on a paper, so I could see how many screens would be
required to perform a function, how easy will be to flip to
one screen to another, how properly and well the functions
will work and finally perform a test to make as smooth as
possible to perform all the functions on the app.

8. The Process
8º Visual
Set all the application graphics, such as, what color to be use,
typographies, sizes, the elements arrangements, choose
icons or animation, and among others details.]
9º Prototype
I used illustrator and Photoshop programs to design all appli-
cation interfaces. As I was projecting, I could review and
change some elements.
10º Usability Test
I did not have time to test the screens with users, but noticed
that the application fit the rules of usability. So I print all
screens , so I could test the application with at least 3 mem-
bers, even so in restricted way because I do not have any
Bluetooth scale. So I asked Libia, Rodrigo and Rui, to interact
with the first 3 basic application functions: Registration,
Insert goals, and view graphs. Some difficulties were encoun-
tered initially because it is a prototype of paper and other ne-
cessities that have to be analyzed in the future.
TOTAL TIMEFRAME: 16 hours

17. Let you know
What were the different stages on your process to create
the proposal?
There were 9 stages as Follow: Similar research, interview,
Wii fit experience, brainstorm, concept, structure, sketch-up,
visual, prototype and usability test.
What were your main setbacks?
TIME! I did not have enough time to do a more detailed
project.
What would you like to do if you had more time to finish
the task?
I would like to insert new functions, improve screens, perform
more tests, So I can improve the application, and find the
wright balance between the App and the user. I also could
analyzed better the error already found on the previews tests.

18. Thank’s for your attention!
