The Egg Mailer DEFINING THE PROBLEM “Design, build and test a package that could be used to safely mail a raw egg, without allowing it to break. You can construct your package out of any combination of cardboard, paper, or foam.” In mailing an object, a package is bound to fall, be pressed and pushed upon, stacked upon, agitated in transport, etc. Further, a package is required to be light (to reduce costs) and have the ability to be handled and transported easily.
RESEARCH & IDEATION
In the initial stage I considered how an egg is handled from the moment it is laid. A picture of a hen gently sitting on her eggs in a bunch of hay came to mind. The softness of her belly and the hay underneath, provide a cushioning and the shock absorption.
an unpredictable environment). Creating a package that is able to withstand the impacts of this unpredictable environment and prevent a delicate shell from breaking constitutes the design problem.
Much in the same way, a bird creates her nest placing twigs making an rounded wall. The round shape of this twig wall reduces harsh impacts and provides a sort of cushioning to the eggs inside and preventing it from rolling out.
Eggs have a very delicate outer covering, which protects the liquid egg yolk inside. One is always cautious while handling eggs (like when bringing them from the supermarket or grocery store), with the fear of them breaking due to falling or hitting another surface. Eggs also require to be transported in certain temperatures (not above 45 degrees) and have an ability to ‘breathe’ so as to not be affected by bacteria and get spoilt.
Shredded paper could create a similar kind of cushioning in a box, if the egg is placed on a frame that does not let it move.
As a part of my process I visited the locally grocery store to see how eggs are packaged and what are the visible clues of the structures that work. This was based on the hunch of weight/pressure bearing features crockery boxes have, in the stiff thermocol supports at the sides, which seem to take the impact and protect the crockery in the middle. These thermocol ‘walls’ also provide strength to the outer edges of the box.
I also looked at how eggs were packaged in the local grocery stores in Japan1, using natural materials. The method of twining prevented the eggs from hitting into each other and crack and also allowed the user to hold the package of eggs in one hand vis a vis the cautious way we use two hands to hold an egg package from the grocery store.
When designing a package for a raw egg to be mailed, one is faced with two opposing situations (a delicate object and Defining the Problem

however, did not seem practical due to too many reasons and was not pursued.
I also considered how the amniotic fluid in the womb acts as a shock absorber and wondered if a jelly like substance could be used which could suspend the eggs. This 1 ‘How to Wrap Five Eggs’, by Hideyuki Oka

STUDY OF EGG CARTONS IN THE GROCERY STORE
I found egg boxes to be designed in much the same way, with protruding supports in between or weak spots which act as shock absorbers in the case of an impact. Deep moulds prevent the eggs from coming out and a little room on the roof of the box, allow for the reduction of impact. Boxes were made using three materials primarily: polystyrene foam, plastic, recycle and molded paper. It was interesting to note that eggs that were broken were mostly towards the outer sides of the box, implying that there is lesser shock absorption or weight bearing capacity here. This exercise was very useful and helped in the conceptualization of my final prototypes.

PROTOTYPE 1 Using my findings above, I wanted to design a prototype which used a cardboard which had good strength to hold its shape well.1
Egg Cartons made of Polystyrene foam and their structural details
In the first prototype, I have mainly given the egg support so that it does not move in its position, and impacted by any surface as a result. The board sheets in which the egg is resting are snugly inserted and provide some degree of shock absorption. Tests performed: Agitation, vigorous agitation in multi directions, drop and weight pressure. While the testing of this box was successful for all of the above, it did not give me complete confidence and I decided to test another prototype using thermocol.

PROTOTYPE 2
I used the same exterior box for prototype 2.1 In the second prototype, the thermocol acts as a wall and pressure or weight bearing support. Being light, it does not add to the weight of the package. This idea was based on the way egg and crockery boxes are designed, ie: to have weight or pressure bearing column.

Tests performed: Agitation, vigorous agitation in multi directions and steep drop. The testing of prototype 2 was also successful.

Info-graphic illustrating my hand and its measurements, average hand measurements of the ethnicity I belong to (Asian Indian). My percantile with reference to these measurements and a comparison to average measurements of women hands in USA, Jordania and Vietnam. This was an interesting exercise, which made one aware of how body shapes and sizes vary across age, gender and ethnicities. The exercise required one to measure their hand, compare it within their ethnicity and determine their percentile. It also required one to research and collect Hand Anthropometric Data of two different ethnicities other than ones own and compare hand shapes and sizes with the data collected. The findings were then to be represented clearly in an info-graphic so as to communicate these measurements and their variety. I began by measuring my hand followed by collecting data of different ethnicities. From the data I collected, I tried to choose two ethnicities which would not be too similar to my region of origin (India) and also had most of the measurements. I also found data of my ethnicity (Asian Indian) and compared my hand measurements to find out the percentile. The numbers revealed that my hand falls in the ‘bigger’ hand sizes of Indian woman. For my info-graphic I referenced ‘Measurements of the Human Hand’ from the book ‘The Measure of Man and Woman: Human Factors in Design’ by Alvin R. Tilley.

How is a seam ripper used?
PROJECT A
The Seam Ripper As the name suggests, a ‘seam ripper’ is a tool used to rip (or remove) a seam (or stitch). It is commonly used by people who sew, when they have made a mistake in the stitching. I chose a seam ripper for this project because for some reason, I never look forward to using it. A mistake in stitching itself pulls you down, added to which I have to use this small tool to rip off tiny stitches. So even though the entire process of ripping a seam is laborious, I feel the tool adds to this unpleasurable experience. I have chosen to use a basic seam ripper and explore better ergonomic design possibilities for it.

BALL TIPPED POINT FOR PROTECTION
TIP BLADE
The tip end is slipped underneath the stitch and the ripper is pushed up and forward so that the blade cuts the thread.

Design Inspiration 1: THE SAFETY PIN The inspiration for these designs is a safety pin. This is usually my ‘go-to’ tool incase I can’t find my seam ripper. The pointed edge of the safety pin goes underneath the stitch, and the rounded section in between helps to pull out the thread when a little force is applied. I intend to use this idea of motion and force, with incorporating a curved tapered blade in place of the pointed pin and curve of the safety pin, so the new seam ripper would function similar to the original one. I also thought of exploring a wider handle to accommodate the thumb on one side and the fore and middle fingers on the other side for a better grip.

Design Inspiration: The Pine Cone The inspiration for this design is a pine cone. Referring to the self designed prototypes made by the test subjects, (especially the one made by Manny), I was thinking about a tool which would fill the palm space between the thumb and the remaining fingers when the fingers curve around to grasp something. This would give them comfortable room and ease from each other. I found this pine very comfortable and suiting this function perfectly with its slight curve on one side and bulb-like form which fits nicely into the palm-space. Interestingly, even the surface of the cone didn’t make the grip uncomfortable but rather provide good traction and had an almost massage like quality to it.
PROTOTYPE 5
These designs would use the same kind of prong that is used in the original seam ripper, with a requirement of a cover on the prong so as to not hurt the user when not being used.
This design is inspired by the pine cone, with a slight bulb like shape to fit into a comfortable grip in the palm. A light curve on one side accomodates the shape of the thumb.
PROTOTYPE 6 This design improvises on Prototype 5 in having small edges protruding where the tip of the thumb and forefinger are placed, to create a no slip feature.

Design Inspiration: THE TOOTHBRUSH
DESIGN SELECTION The seven sample prototypes were tested by four users (user was asked to pretend to rip), who had participated in the initial test. Of these, three designs were the most popular based on user feedback and selected to make final prototypes.
The inspiration for these designs is the tootbrush. On referring to the manner in which the test-subjects preferred to hold and use the self-designed tools, I found the tooth brush come closest in resemblance to the kind of grasp and motion that was required for the tool to be designed.
This in-between step also gave me valuable insights and feedback by the users like: • Use of a soft material (e.g. silicon) in the front and back for better grip and comfort, like is seen in kitchen tool handles;
I referred to the kind of design details that are considered in toothbrushes to make it a better product ergonomically (no slip grips, use of flexible materials on the sides where the thumb and fore-fingers are placed, slight curves and protrusions) and this guided my designs here.
• Better grooves for the thumb, add some ‘cushiony’ thing; • More length in Prototype 2 to accomodate the little finger; • Accomodate left handers; could be reversible; make something universal;
These designs would use the same kind of prong that is used in the original seam ripper, with a requirement of a cover on the prong so as to not hurt the user when not being used.
• Some prototypes are good for one hand positions only, which limits it;
From top to bottom: Prototype 1, 4 and 5 from the earlier samples become new Prototypes 1, 2 & 3.
• ‘Personality’ makes it more interesting (e.g. tear drop like shape of Prototype 1); • Incorporate a pivot like cover for Prototype 1 which is attatched to the tool itself and therefore is not easy to loose; • Incorporate a little groove so Prototype 1 can be hung to your keychain; • Add into the handle, (like a double tool, one inside the other), a tweezer to remove the tiny remnant threads from ripping;

It was interesting to note some of the outcomes like: • All three users chose completely different prototypes; • What was comfortable for the two women test users was not comfortable for the male test-user; • Putting a blade/needle changed the function of the handle considerably and left scope for improving the design; • There is scope of re-designing the blade with the handle to make a better seam ripper;
Feedback
• Likes the hold of this the best; • Prefers the blade/needle on the other ones better; • Finds needle not pointed enough to go underneath the thread;
• Good;
• Not bad;
• Not too sharp - prefers the other blade;
• The grooves make it easier for traction;
• Shape is ‘OK’ - a little too big, will not be comfortable if someone has to do it for a long duration;
• Pointed needle is easier than the others;
• Finds it convenient;
• Adding a cushion to the surface would make it more comfortable;
• Likes this one the best;

Of the designs, Prototype 2 was the most popular. The contoured shape at the back and depression for thumb in the front makes it a comfortable hold. This seam ripper also has the possibility of being used both by a left handed and right person and is accommodative that way. Further improvisation in design would be to • add surfaces which offer a slight spring/flexibility and grip;
PROTOTYPE 2: This design was no most preferred.
• design a cover to protect the user from the blade; and • add a tool/surface as part of the design to pick up small threads after ripping; This was an interesting exercise and helped one analyze the function of a tool and its relationship with the user. I feel I was able to come a long way from the seam ripper I started out with to satisfy the criteria of comfort and functionality to some extent, with more informed design directions to make a product which could become a realistic choice for a consumer.

Design for removing extra threads:
GOING FURTHER...
After ripping a seam, small portions of the thread are left over on the fabric, which are cumbersome and time consuming to remove. If left, they get stitched onto, becoming little pieces of thread popping out here and there. I would like to consider incorporating a surface on a portion of the tool which would help remove these little pieces of thread to some extent. A surface which creates some kind of friction, and is yet really soft and not sharp comes to mind. The following are some design inspirations I intend to explore:

2. I would like to also design covers for each tool to protect users from getting hurt; 3. I would like to consider if a part of the tool can be designed to rub off/ remove the little threads that stay on the fabric when a seam has been ripped.

PART 1: APPLIANCE USE ANALYSIS In the first part of Project B, ‘Simple Appliances’, we were required to select and analyze an apparently simple appliance. For this, we identified a task that can be performed on the appliance to test. Each step of the task was recorded in the form of instructions using the ‘talk aloud method’. This was followed by analyzing and critiquing the process, paying special attention to pain points. The instruction and analysis was then compiled in a one-page document. For this project, I selected my GE Over the Range Microwave and the task of defrosting cottage cheese with a delayed start. I chose this particular task because I had never undertaken it before and would be carrying it out as a first time user.

2. I really like the ‘time-cook’ button which allows me to custom feed the time I need to cook an item. My button stopped working, so I am accomodating its absence by using a round number or adding 30 seconds. This is inconvenient in that I need to keep waiting (incase a food item needs to be warmed for say 2:15 seconds), I have to keep watching till 45 seconds are left and then press stop. 3. The microwave has a ‘Help’ button. Clicking it allows me to get information about the other buttons. So say I want to know about ‘Defrost’, I click ‘Help’ then click ‘Defrost’ and the display guides me on basic steps about defrosting and how to go about it. Really love this feature.

1. I don’t use all the keys on the interface. Have never used ‘Popcorn’, ‘Potato’ and ‘Beverage’ also. I usually use a predetermined idea of how much time a food item may take (like if I have to reheat the tea/milk).

Brewing a Cup of Coffee
Based on the analyses of the appliance selected, we were to write a set of design guidelines that describes the appliance and task, identify a target user group for the redesigned interface and include a list of design criteria.
Steps to brew a cup of coffee: Coffee maker interface
1. Push the power button to begin the coffee making process: When the power button is pressed, the coffee maker turns on and several lights shine.
Power Button
2. Filling the water tank: The blue light indicates the water level is low. The first step in filling the water tank is to remove the tank from the system.
5. Place the coffee container cup into the place provided.
6. Place the coffeee mug in place below the coffee dispenser.
This was then followed by brainstorming as a group to develop a new approach to the interface of the appliance. It was also required that the redesign should be a possibility in the near future and to that extent we should extend the possibilities.
7. Using the handle, close the coffee container storage unit. It will click in place.
Water Tank
Fill Line
3. Filling the water tank: The second step in filling the water tank is to remove the lid and fill with water up to the fill line. Either hot or cold water can be used. During the time it takes to fill the tank, the coffee maker is able to heat itself. 4. Opening the coffee container storage is the next step in the process. Using the handle, life up and open.
Jennifer’s Analysis of ‘making a cup of coffee with the Keurig Coffee Maker’ 48
Poorvi Das
Ananylsis: The coffee maker is a fairly simple appliance to use. The power button is easily located. Once the coffee maker is turned on, it needs to heat up. There is a light indicating it is not yet hot enough. However, if the user is not aware that it needs to heat up, they may get frustrated when the next steps are not able to be followed without indication of what’s going on. If the water needs to be filled, this is not an issue because it will heat up in the time it takes to fill the water tank. Removing the tank is an easy task, but it does take a new user a little while to figure out how to remove the tank. Placing the coffee cup is a simple task, but the user must have purchased the correct coffee cups, or they will not fit. Occassionally, when the lid is closed, the blinking lights don’t come on as expected. When this happens, it takes a while to get the coffee maker back on track to brew the coffee correctly. Choosing the cup size is a great feature. However, the pictures indicating size may be confusing to some people on which is actually smaller and which is larger. It takes a second look until you get used to the machine. Opportunities for imporvement within the user interface consist of fixing the glitches that cause it to get off track in the order of the process along with a new method of choosing cup size.
Cup size
8. Choose the cup size and push the corresponding button. Each button represents a size option and is indicated by a picture on the button.
9. Wait. The coffee is brewing. It can also be very hot, so giving it time to cool down is a good idea.

In this part of the project we were to select a task as a group after reading their analyses from Part 1.
The group chose to redesign Jennifer’s appliance, the ‘Keurig Coffee Maker’, with the goal of improving a good design. Jennifer’s Analysis of the Coffee Maker while performing the task of making a cup of coffee, included the following pain points: 1. The current single serve coffee maker can have a confusing process to a new user. The experience is not clearly outlined and when the user does not follow the right steps, the machine can get off track and it can be difficult to figure out what needs to happen to correct the problem.
the wrong type will not work with the particular machine. 3. The cup size icons can be misleading. It is hard to tell which icon is larger or smaller and it is also hard to know if your cup is considered small or large. 4. The current coffee maker has an autoshut off that stays on for an hour before automatically shutting off.
DESIGN GUIDELINES WHAT?: A coffee maker that makes you want to wake up. HOW?: By having your morning cup of coffee brewed, ready and smelling fantastic! FOR WHOM?: Someone who could use some coffee to get out of bed and make sense of the world. WHAT ELSE? Description of function
Corresponding Design Criteria
Based on Jennifer’s analysis and in keeping with the intention of making the appliance clever through smart home technology, the group decided to combine smart phone technology with WiFi capabilities to prepare the first cup of morning coffee a few minutes before the alarm went off.
• Predefine time for coffee brewing on the coffee machine or on smart device through an App.
• Built-in clock and alarm system; Ability to connect wirelessly with device, which syncs defined setting with machine;
• Makes the task of making coffee as simple or simpler than pushing a single button.
• Touch screen interface; Predictive technology to learn from user habits/ preferences
With this intention we created a set of design guidelines and criteria as well as an initial flow diagram of the steps to undertake the task of making the morning cup of coffee. The target user was a person who likes to have their coffee first thing in the morning.
• Can turn brewing on when in another room
• Ability to connect wirelessly with smart device which syncs action with machine
• Move around and place it anywhere
• Compact, convenient, lightweight, simple.

THE NEW DESIGN
SCREEN DESIGNS FOR PROTOTYPE
To correct the pain points, the new design interface has simple, direct instructions detailing the process so the user does not do things out of order.
Enjoy Later:
There is a touch screen, similar to a smart phone that will clearly state what the user needs to do next. In addition to the touch screen, the coffee maker has the option to be set manually to a timer or to sync with the users smart phone to allow a connection between the smart phone’s alarm and the coffee maker. The coffee maker will turn on and brew the cup of coffee as the alarm goes off, so the user’s coffee will be ready automatically when they wake up in the morning. The coffee maker has a sensor that will sense the size of the cup, eliminating the need to choose a size. The new coffee maker will have coffee pods. These pods are similar to a coffee bean that will react with the heated water to brew a cup of coffee. They will eliminate waste because they do not require packaging.
Enjoy Later: Sync to phone
The new design will also be battery powered, making it portable even away from an outlet and it will automatically turn off after 5 minutes of inactivity, rather than an hour. So it not only saves on waste, but also on energy.

PART 4: DESIGN PRESENTATION (Group)
CONCLUSION Based on the results of the user test it can be concluded that: • This design will be appreciated by a smart phone user. A person who is not accustomed to a smart phone might find it confusing; • The overall design aesthetics was appreciated by everyone; • While the user interface was appreciated by everyone, a few functions related to setting the alarm were confusing; • All the users were willing to download and use the App.; • The new interface was preferred as compared to the old one because of its simplicity, convenience, clean and inviting appeal;
Group Members: Shannon Madden, Jennifer Frame & Poorvi Das
In Retrospect If I were to make a few more changes to the design they would be to: Be able to set the coffee while setting the morning alarm from the phone directly. A few of my sketches included a coffee cup icon to set the coffee while setting the alarm. This reduces the number of steps considerably, which makes it more convenient and user friendly
The process and Redesign of Project B was finally compiled into a presentation to describe the redesigned interface, present prototypes and communicate the results of the user testing. The group decided to have a documentation approach keeping it brief and crisp. The presentation can be viewed at the following link: https://www.youtube.com/ watch?v=jiwjoVqN9FI&list=UUvxT48pBpL08Lo7dP8fbCAg
Instead of the Keurig Machine we considered, for the redesign I would suggest a smaller size ‘Mini Keurig’ or ‘Mr. Coffee’ kind of machine because it is easily portable and does not take too much space. This was part of our design criteria.
• Most users loved the feature of setting up the coffee ready for when they wake up and also being able to do so using the phone; • One user mentioned the possibility of it syncing to the alarm setting screen of the phone so the morning coffee could be set directly while setting the alarm;

Twice a week the mail-box is filled with newspapers and supplements and a bunch of savings in the form of coupons. While I didn’t realize the importance of these earlier, over the years I have gotten the hang of how these work and try and use one wherever I can. I find this a smarter way to shop, by purchasing a product for lesser than what I would normally have had to pay without the coupon. I also believe small savings pile up to become bigger savings and opportunities.

Like how coupons are compiled in supplements of the newspaper and not mixed up with general supplements, making them easier to identify, keep aside and sort.
Discard?: Sort as per expiry date and keep aside either in car or bring coupon bag home to sort and discard. (5-10 mins.)
*Note: When I’m in a hurry I take the whole coupon bag into the store and do the sorting & finding inside.
Too long a process to sort, cut and discard.

Less waste of paper in comparison to coupons that come in the mail. Still, sometimes only one coupon prints on a whole page of paper, leading to waste of paper. Some coupon sites (e.g. Michaels) allow you to choose the coupons you want before just printing out all of them even the ones you don’t need, thereby reducing the waste of paper to some extent.

PART 3: DESIGN (GROUP PROJECT)
Based on the tasks analyzed and illustrated by the group members, the group selected one task to analyze and develop designs for improved environments and processes.
INFOGRAPHIC by Jennifer
Group Members: Shannon Madden, Jennifer Frame & Poorvi Das
We decided to move forward with the task of ‘Organizing Coupons’ as it showed the most potential for a better and more effective redesign.
Poorvi and infographic created by Jennifer and discussed potential directions on how this service could be improved and made fantastic.
As per the task description, infographic and our individual experiences, key gaps in the process were:
Poorvi came across an article about the recent introduction of the “Walmart’s Scan & Go Service.” where an item is checked out and paid for directly, by scanning it on the phone, thereby saving the wait time in check out lines. This inspired us to look at using a smart device to make the process of couponing easier and faster and also address the massive amounts of paper wasted in the traditional method of using coupons.
• Wastage of paper; • Time consumed searching, sorting and cutting coupons; • Wastage of coupons because of not keeping track/ organizing well, getting misplaced; • Extended check-out time; and • Inability to sort and find the right coupon to use at the right time, especially before they expire;
After an initial session of brain storming, we decided to work on initial ideas for improvement independently, so as to have varied view points to select from, in our redesign.
Identifying multiple opportunities for improvement, our group aimed to make this process easier and allow more users to save money by creating “Couplify”, with the goal of simplifying the process of couponing. To achieve this, we referred to the task description of organizing coupons by 72

JOURNEY MAP/ BLUE PRINT FOR NEW DESIGN
SYNOPSIS FOR RE-DESIGN There were many directions that we could have taken for this service and we got some good suggestions from the class about considering loyalty programs and budget assistance. However, after thinking long and hard, we decided that it would be best to focus on one particular consumer, in this case a person shopping for groceries exclusively. After considering our initial pool of ideas and feedback by peers, we had a mind map of the goals and features that would go into making this service effective. We nailed down logistics of what the service can actually do for the consumer and created a journey map of the customers experience from the moment they receive coupons to the point of purchase, in order to ensure our service met the needs of our user along each step of the way.

Poorvi Das
Based on our individual ideas for the re-design, we decided to work on an Application and Website with the following goals in mind:
Key Features include:
REDUCE PAPER WASTAGE
Phone Notification if a particular item in the list has gone on sale;
ASSIST WITH EASIER ORGANIZATION & USE OF COUPONS HAVE THE ABILITY TO CREATE A SHOPPING LIST TO SYNC WITH ONGOING DEALS
A Master Coupon that combines savings of similar coupons into one;
Adaptable Organization as per shopping list, sale, coupon or store; Ability to scan and save print coupons with a phone;
FASTER CHECKOUT AT THE STORE

In its final form, Couplify consists of a website manager with a phone application for easy use. They work together to provide the consumer with the maximum amount of savings in the smallest amount of time.
The user has a unique username and passowrd which syncs the website and Application. So all changes made on the website or application are co-ordinated.
The website allows a user to create their unique shopping profile, which can be accessed from anywhere, anytime using a username and password login. They can browse from a category of products, create a grocery list, scan through available coupons, select a store to shop at, and save their preferred lists and settings in (My Couplify). Jennifer’s initial idea was that the website and app. could have multiple ways to use it, where the user could search for coupons based on the store or based on the item. For example, if the user wanted a coupon on a particular item, the service could provide them with the store that has the best coupon for that product. However, we eventually decided to abstain from the complications of splitting up items on the grocery list and focus on finding coupons by desired stores instead. Our reasoning for this was that most consumers prefer to shop at one store at a time.
BUILD YOUR GROCERY LIST The user can build their grocery list by browsing and selecting items. A list of favorites, based on items the user regularly shops for shows below for easy addition into the grocery list.
After reading up about the way coupons and deals work and the cyclic patterns they tend to follow, Shannon suggested that the service could help users track the sales cycle for certain items in order to stock up when they are cheapest. As everything can Poorvi Das

SELECT COUPONS BY CLICKING ‘COUPLIFY’
not be on sale at the same time constantly, a feature that gives a heads up and helps with the more detailed parts of couponing would be useful to shoppers. We decided to make the program “smarter” by searching and selecting coupons from multiple sources for the user, based on their grocery list. Remembering the users shopping preferences, in order to predict a list of items that a user shops for repeatedly or in a pattern are a part of it. As per Poorvi’s initial ideas, we thought that coupons would automatically be deleted and refreshed as per their expiration dates.
As the user builds the list, the cloud simultaneously scans for relevant coupons and predicts the savings.
Poorvi’s idea for the website included the user having the flexibility of using, removing or sharing a coupon from the database.

The website is synced to the Application on the users phone to give the user easy access to their coupons and shopping lists while shopping. Syncing the phone app with a cloud service allows the database of coupons to be available to the users in the palm of their hand.

We incorporated Poorvi’s suggestion of using the phone to capture paper coupons that come in the post, to be added into the database. We all know the mail box coupons will not stop arriving, and having such a feature will come in handy. It will also be something that will please ‘the crazy coupon lady’, because she for sure, can never have enough of them! Shannon had an idea about email notifications which we incorporated in the redesign. The app will give the user an alert when a coupon is entered into the database that matches an item they frequently purchase. The user can choose to add the item to the list if they’d like. Based on an idea inspired by peer feedback, we decided to incorporate a voice recognition feature enabling the user to speak out their grocery list to the Application. As per Jennifer’s idea, when the time comes to shop, the user can scan the bar code on the items they put in their cart. This sets the program to search and apply relevant coupons, enabling the costestimating feature of the Program. When grocery shopping is complete, the app will have kept track of the estimated cost and savings. It will also combine all the savings into a single, master barcode for the cashier to scan, thereby saving a lot of time for the shopper, cashier and the people in line behind!

PART 4: DESIGN PRESENTATION (Group Project) Group Members: Shannon Madden, Jennifer Frame & Poorvi Das
The process and Redesign of Project C was finally compiled into a presentation to describe the redesigned task, present prototypes and communicate the idea. The group decided to have a documentation approach of the process and contribution of group members with more emphasis on visuals. The presentation can be viewed at the following link: https://drive.google.com/ file/d/0Bzjc4uYokfdHczFKRmgzS3pCdW8/ edit?usp=sharing
During our process of designing the idea we came across (through peer feedback) of similar offerings by coupons.com and cartwheel by Target. While these were a little demotivating, we analyzed them and worked on adding features superior to the ones that existed. Here are some of the features that make ‘Couplify’ a superior service: • Couplify allows one to scan for grocery coupons across stores instead of restricting it to one; • Create a grocery list to sync with coupons; Poorvi Das
• Scanning the barcode of the item in the store to search for available coupons instead of having to search for one; • Adding print coupons by photographing them by phone;
useful for people who not only use coupons extensively, but by those who might find the extra savings very helpful. A few of my sketches tried to address this point in the previous sketches looking at a way to ‘share’ in the store. It was not eventually taken further as we decided to focus on smarter technology to re-design the task.
‘The Human Factor, Design Thinking’, was a very interesting course encompassing many aspects of the design process. It included interesting and challenging design projects around packaging, tool handle, infographics, user-interface and service design, thereby giving one a holistic perspective of the design process. Each project revised and strengthened the core values of the design process.
• Combining all the coupons into a Master Coupon Code;
I have learned the value of approaching design with a focus on the needs of the user and the many considerations one needs to use for this including ergonomics, task analysis, etc. I also enjoyed employing and testing the Design Process, especially the Double Diamond Research and Design Process through the projects covered in the course.

• Create a grocery list on the phone using voice detection abilities;
CONCLUSION
While, I love our design solution and direction for the task, I realized in Project B, that one takes for granted that everyone has a smart phone, when this is not usually the case. A large number of people do not use a smart phone or are still grappling and are uncomfortable with technology (like aged people, people not having the financial means, etc). It would be interesting and challenging to design keeping this target consumer in mind. Many coupons are wasted in the process of trashing the ones that will not be used or by people who do not use coupons at all. These would be
