3. System Concept Statement
✤ The “Refrigerator Tracker” aims to help housewives and her family members through
effective organisation of the refrigerator by allowing the users to check out what is
available and the products’ date of expiry.
✤ The problems that users face while using fridge are followings:
• Users are not able to exactly track what they need to buy and what they don’t
necessarily need to.
• Users are not able to check the date of expiry of all the food thus resulting into the
food decaying.

4. System Concept Statement
✤ In order to solve such problem
✤ keep records of product information (expiration date and its name)
✤ collecting data from companies of food industry
✤ We are trying to employ a technology of reading alphabet characters from a receipt in
order to save such data.
✤ Once the words are read from the receipt, the application will save the name of
product and expiration date.
✤ The application will provide information about best grocery store for each day depending
on the products that need to be purchased.

5. System Concept Statement
✤ Design vision
✤ Fuse IOT (Internet of Things) into daily lives of housewives
✤ Close connection between the fridge and application
✤ Recommendation of grocery store
✤ Create a communication between the stores and application
✤ Provide information through Internet

Her daily routine is simple. She meets her friend who lives up stairs. After drinking a cup of coffee she prepares for
dinner. She goes to E mart every week and buys everything she needs. However, she always forgets what to buy and
sometimes buy things that are already at home. Her spare time is spent on cooking, cleaning, online shopping, and
watching TV.
PERSONALITY
: Conservative. Sensitive.
: Usually in a hurry. Feels stressful when things do not work as it is scheduled
: Feels shy to ask questions to strangers
ABOUT_USING THE FRIDGE
: Unorganised. Does not know what is in the fridge and when she bought the product. Mostly throws away one fourth
of the groceries.
ELECTRONIC DEVICE USAGE
Knows how to use the basic functions. Uses the computer to watch TV dramas, internet shopping and to pay
checks. Internet is the only program that is used.
Changed to a smart phone because of kakao talk. Still is a fan of ananlouge style phones. Is currently in the stage of
learning new functions. Now she is able to download, update and search for applications. Her phone is mainly used to
communicate with others via kakao talk, kakao story and phone calls

8.
He is a hard-working, ordinary office worker. On weekdays, he usually returns home quite late due to workloads at
office. He ends his day with a can of beer for sound sleep frequently, so he usually drops off by a near-by store on the
way home to pick up a can of beer. On weekends, he takes some rest at home rather than going out.
PERSONALITY
: Quiet, diligent and devoted to family. Even though he loves his children, he doesn’t have much communication
because he isn’t very talkative. Easily stressed.
FRIDGE USAGE
: Because he doesn’t have much time to spend at home, doesn’t have a sense of what’s going on at home. Lack of
communication leads to frequent overload of same product in fridge. Has difficulty in finding food from fridge without
wife’s help.
ELECTRONIC DEVICE USGAE
: Being a worker of digital appliances, he is very familiar with digital devices. Has a lot of chance to encounter new
digital devices in workplace for further study, and has no difficulty in getting used to new devices.
He is a fluent user of smartphone and is sort of an early adapter in digital devices compared to his age. He is very
interested in new functions of smartphone and is always curious about new functions upcoming. He is also wiling to
use many new, attractive functions of smartphone.

9. She is a high school student, very friendly to her mother. She is one of the best friends for her mom. Like typical
girls, she is fanatic of sweets and crisps because she gets rid of stress of studying by eating delicious foods. She
can’t endure the moment without sweets for her psychological sake, so she either brings one from home or buys
one.
PERSONALITY
: Very outgoing, talkative. Very organised and she has an obsession towards organising stuffs.
FRIDGE USAGE
: while at home, she often helps her mom with cooking. She often runs an errand for her mom while cooking, but
surprisingly she can’t cook herself. Do rather she helps with small things like placing the food into the fridge and so
on.
ELECTRONIC DEVICE USGAE
: Being a young generation, she spends most of her time with smartphone in her hands. Her push alarms are
always turned on because of kakaotalk, and she plays a lot of attention to the push alarms for feat that she
might miss some messages. Her smartphone is full of interesting applications, and she downloads most of the
suffused applications when seen on SNS. Her phone is connected with her iPad as well, and many functions a re
shared in between them.

22. Interview

23. I usually purchase cheap products
or organic products.
On weekdays, I usually go to
grocery stores nearby my house.
On weekends I tend to go further
because I have my husband to
drive then.
I prefer Hansalim mart but go for
different place when some
products are missing. For
vegetables, fish and meat I visit
Nonghyup, for frozen food Costco,
and other foods I purchase at E-
Mart.
For vegetables and other
fresh products, I go to
traditional markets. When
buying industrial products,
such as flour, I go to big
markets.
I prefer E-Mart the most
because there is wide variety of
products, and the price is
reasonable.
I especially like the promotion
during night time near closing
time. Also, it seems that they
are selling only fresh products.
Q. What type of mart do you prefer?
Why?

24. I go shopping t
week.
I only purchase small amount
at a time when necessary. I
go to markets when I run
out of certain food.
I go grocery shopping twice
a week; once on weekday
and once on weekend.
I don’t have a fixed plan for
grocery shopping.
I go grocery shopping
once in two days.
As our family consists
only three people at the
moment, I only buy small
amount as a time. I don’t
buy large amount at once.
Q. How often do you visit the mart?
When do you visit the mart?

25. I prefer Costco. I don’t go
shopping by myself, however,
when I go shopping with my
wife I always ask to go to
Costco. There are lot of
American products and sell
in huge quantities.
I don’t use the fridge so I am
not familiar…
I go to a close super market. I
only buy junk food unless mom
asks for some milk.
I only know what my mother
told me to eat. I don’t know
what to eat when I am alone so
I just eat things that looks
good.
I don’t have any preference. I
just follow my wife.
I sometimes prepare food for
my family so I know the basic
things in the fridge.
Q. What type of mart do you prefer?
Are you familiar with the fridge?

26. I want to use various apps so I
download quiet a few. However,
due to my age I am not fluent
in using the apps.
I read comics and use
kakaotalk mostly. I don’t have
much difficulties in using apps.
I don’t have much difficulty
using smart phones. I am
friendly using electronic
devices and try out different
functions. However, when I
have difficulties I ask my
daughter for help.
Q. How good are you with using your smartphone?
