1. EMPATHY

In today’s stressful life of ours, we usually have a habit of either forgetting or misplacing

our important belongings. We end up spending lot of time to trace the lost things or at times we

lose it forever. Things that we are not able to find at required moment loses its value. For example a

document required for an interview if not traceable on the day of interview, it is likely to happen

that we incidentally find it after a week or later.

The above such incidences are supported by the well known Murphy’ Law which can be rewritten

as, ‘‘anything that can be lost will be lost’’.

The following incident demonstrates the above.

HAPPY STORY

It was yet another working day for Rekha to her office. Rekha is a working woman who

handles her family at home as well as employees at her job. Like any other working woman, she has

got a stressful life at both the places. She was lucky today to reach office on time. She parks the

vehicle and rushes to the work place. At the end of the day, when she gets ready to go home, she

realizes that her vehicle key is missing. She searches her drawers, purse and all likely places but she

is disappointed. She then remembers that in the morning in hurry she had left behind the keys with

the vehicle in the parking place itself. Now she is tensed whether her vehicle will be at its place or

not. She rushes towards the parking place. She gets relieved when she sees her vehicle and the key

at the place where she had left behind. Rekha thanks the God for the favour.

SAD STORY

Let us see Rahul’s incident.

It was 10 am of Wednesday morning. Rahul was getting late for his office. The bell rings

and there arrives the officers from municipal authorities. They wanted to verify the ownership rights

of Rahul’s house. They demand for the documents while sipping the cup of tea offered by Rahul’s

wife. Even after an extensive search of the asked documents, he could not find them. Rahul started

requesting the officers to visit on some other day. But the officers were adamant and coldly told

Rahul that they are marking house occupier as tenant and if Rahul wants to change the ownership

status, he has to visit the respective office along with necessary documents and carry out the

procedure again. Rahul was disappointed as he would have to waste another leave to settle the mess.

The above incidences and many such others prompted us to think of the need of a gadget which

could prove handy and save people from avoiding such troubles.

So we grab the opportunity to propose the development strategy for a product which can

prove useful in such occasions.


Page 4 of 23

Under this process we had thought of numerous test incidences where need of Item Tracer is

felt. We then narrowed down to Users and Stockholders from the test incidences. Then we listed the

likely activities in which users may be involved requiring the need of the proposed product. These

were systematically listed under the first canvas named ‘Empathize Canvas’.

USERS:

The idea of the product that we have come up with is meant for the following persons:

Persons having weak memory

Persons having forgetfulness behavior under tension

Persons who misplaces important keys or documents readily

Persons travelling by public transport with luggage

Persons travelling by public transport carrying important documents

The intended user can be any person, here are some sample users:

A student going for admission carrying important documents

An employee parking vehicle in hurry and forgetting the keys behind

A housewife securing important belongings in some drawer

An employee misplacing some vital contract papers

STAKEHOLDERS:

Due to such forgetfulness behavior, people or organization who would be indirectly

affected are public transport, admission office, interviewing committee, thieves, civil

administrators(for eg. police).

ACTIVITES:

The activities carried out by our projected users are:

Travelling with important document and luggage

Strolling in public places such as street markets, gardens, etc.

THE EMPATHY CANVAS


Page 6 of 23

2. IDEATION

Within the Ideation phase, we select a test case where we have more have emotional

attachment and solutions for the problem faced by the people in the selected test case are considered

further.

PEOPLE:

Persons having forgetfulness behavior under tension


Travelers

Students

Women

ACTIVITIES:

Travelling with luggage via public transport

Carrying important documents while approaching for an interview

Forgetting the keys while parking the vehicle in hurry

Women wearing ornaments in public places

SITUATION/CONTEXT/LOCATION:

A person travelling for three days with luggage by train. During night time, there is

risk that the luggage is stolen

A student heading for an interview forgets his important documents in the bus

A lady wearing ornaments at public place with the risk of ornaments being snatched

away

A working official parking his/her vehicle, forgets the keys with the vehicle in the

parking itself


Page 7 of 23

PROPS/POSSIBLE SOLUTIONS:

While analyzing the user problems, we came up with various possible solutions’ scenario as

under:

1. We could have a GSM/GPS transceiver module attached with the item to be secured. The module

will continuously send information about its location to the smart phone carried by the user.

Pros:

Accurate location of the item

All modules are readily available

Cons:

GSM Transceiver module is costly

2. A Bluetooth device can be attached with the item to be secured. So that when the item goes out of

range, the communication between the Bluetooth tag and the smart phone is interrupted, and the

user receives an audio message about the same. An android application can be developed for the

same.

Pros:


Page 8 of 23

Cheaper and easily available

When the item goes out of range immediate information is sent to the user

Cons:

Doesn’t provide the location information

3. An NFC (Near Field Communication) tag attached with the items that remain close enough to the

body within 1cm range. Examples of such items are wallet, ornament, etc..

Pros:

Cheaper and readily available nowadays

Cons:

Range is limited within 1cm

4. We could think of tags that are painted with frequency selective paints. These tags will respond

differently to different frequencies. RF transceiver module can be used in smart phones with

appropriate android application. The whole system will function analogous to a RADAR.

Pros:

Cheaper than GSM

Position data can be readily made available

Doesn’t depend on GSM Network for functioning

Cons:

Range is limited to few tens of meters (although apt for our requirement)

New technological development is required

THE IDEATION CANVAS

3. PRODUCT DEVELOPMENT

PURPOSE:

The purpose of our project is to design a handy product that should perform the following

functions:

When the user goes out of range of the item, he should get a warning in the form of

an audio message

When the item is within the range but is not traceable, the user should be able to

trace it


Page 10 of 23

PEOPLE:

The people to whom our product may be useful are the persons who wants to keep their

things secure.


Travelers

Students

PRODUCT EXPERIENCE:

After the introduction of this product, the user will feel relaxed as he will no more lose his

belongings/items/important documents. And if any item or belongings are lost, he will be

easily able to trace it.

As the product is handy, he is not over burdened while using it.

PRODUCT FUNCTIONS:

To help maintaining things within a safe range

To help finding the misplaced things

PRODUCT FEATURES:

The smart tag will be Bluetooth enabled. It would be interfaced with the user’s phone and

when the communication breaks, the alarm is generated on the phone. This indicates that the

product is out of range.

Moreover the smart tag is easily attachable with the belongings.

RF Transceiver Section: The suitably modified smart phone will transmit the RF signals

that would be responded by the smart tags that are painted with frequency selective paint.

The android app will show the location on the phone.

The phone needs to have auto-rotation function to record the received data from the smart

tag.

COMPONENTS:

The final product has two components


Page 11 of 23

CUSTOMER REVALIDATION:

The autorotation function requires dedicated vibrators that will increase the cost of the

product. The autorotation function can be manually handled.

REJECT, REDESIGN, RETAIN:

The product is redesigned without the auto-rotation function. So the user needs to manually

rotate the phone in steps of 90 degree rotation.

[email protected]

Initial Idea

As we have worked together in Design Engineering workshop, I found it very useful. We

think that this subject is very essential in our day to day life. By studying this subject,

student can identify real time problems or we can say it as user’s problem. Also they can

understand how to find solution of user’s problem. By making this all canvas models,

students can understand design flow of any product.

Feedback

After attending this workshop, we feel that it can make revolutionary change in Teaching

System.

1. We should implement it on Big level so all can understand importance of it.

2. Also we should organize it for the students.

3. It requires proper marking system.

Day-1 User Canvas

Basically there are four sections in User Canvas,

1. User

2. Stakeholders

3. Activities

4. Story Boarding


Page 17 of 23

To fill user canvas, we have studied problems of transport sector. Then we have seen

that most of the users (driver) are suffering from manually controlling Viper in rainy

season. So our target is to prevent accident in rainy season.

1. So we have written the following user like truck driver, car driver, bus driver, jeep

driver etc.

2. Stake holder means the sector which are related to our problem for example, RTO,

Traffic police, Auto company, Garage etc.

3. In Activities Part Driving, Music Listening which is related to our main target area.

In Activities All the things that you are doing while driving a car.

4. In Last portion of this user canvas stories can be written either Happy or Sad while

facing the problem. In our case related to Rainy season story can be when Hero is

driving car suddenly rain is started and his car is strike with the Heroine Car due to

Heavy rain and manual control of Viper System.So , this story have two part Happy

As well Sad.
