1 Introduction This report will explain the creation and choices made for the design of a concept/product that will help elderly “aged 65 Years and older” with making healthy choices in the supermarket. It contains the analyses of their behavior while shopping, scenarios, persona’s, QOC, user tests, expert evaluations, and heuristic evaluations, … In short; everything needed in order for the creation of this smart shopping assistant. This Research has been done Autumn/ winter 2012-2013, for the current generation of elderly at that time period.
2 Design case | Project description Design specified for elderly aged 65 years and older who deal with health problems that influence their nutrition choices. The outcome should comfort the user with choices they make during their shopping specified to their diet. Regarding its appearance it is a necessity that it is an attractive product to the user group, which they feel they can relate and relay to. The basic functionality should secure a system that helps the target group to make a (more) healthy choice regarding their diets on a daily basis while shopping at the supermarket.

3 Analyses 3.1 storyboard In order to understand the task of shopping completely the following storyboard was created. Please mention that this is a total random scenario created by an individual. There are multiple situations and scenarios possible.
A second storyboard can be found in the appendices
1. Women , aged 71 prepares shopping list at home. 2. Women enters the store + picks shopping basket + takes list 3. Chooses where to start + checks promotions in folder 4. Ask for help where to find certain product on the shelf 5. Has to ask help again to see if it doesn’t contain any salt. 6. Product isn’t fit for her, so she has to pick her familiar brand. 7. Women goes to the register to pay 8. Exits the store 9. At home , puts her grocery’s in the fridge Students Jort Band s100824, Anouk Van Ranst s128835

3.2 User characteristics -‐ Man/women aged 65+ General Elderly people intend to take time for certain activities; in general they are a little bit slower than other age categories. They have certain cognitive limitations. The current generation of elderly (anno 2013) hasn’t been actively introduced to deal with technology on a daily basis in life. Elderly who do are familiar with technology for strict personal use and have learned it due to their own interests. In general they seem to have little trust in new technology. This generation needs guiding when exploring new things, since they seem to fear to break stuff/ do something wrong. They are very routine driven and like to plan in advance.
Shopping Concerning the shopping behavior of the target group we could say that intend to take their time for shopping, make very clear choices related to brands both cultural and historical. Often they want more information due a health issue. This is something that they in general take very serious and want to pay attention to. Price is a very important aspect either in the expensive or in the inexpensive way. For some products they are willing to spend more in order to the quality and vise versa. Routine and habits are a very important factor while shopping. Personal assistance / attention is very appreciated. The Target group considers shopping a social activity, way to get in contact with other people. They often enjoy the task. They buy smaller quantities and have little 1 or 2 person households.
This information is the conducted result of a conjunction of confirmed assumptions and 8 interviews we held to get to know our target group. Out of these interviews we were able to describe 2 personas, which we will use to describe the requirements later in the design process. The interviews can be found in the appendices Students Jort Band s100824, Anouk Van Ranst s128835

3.3 Experience Goals
For the assignment we had to set-up a list of experience goals for our design. Below is the final list we made for this.
-‐
Effectiveness Can they use the product to aid them in finding healthy food?
-‐
Efficient to use The product should not interfere in a major way in their shopping time; this means that you have to get the information fast and easily about a product.
-‐
Safe to use Because we are giving users information of healthy and healthy food we have to check if they are allowed to eat certain food without taking a major health risk.
-‐
Easy to learn The product should be easy to learn in the way that it requires a onetime explanation or less, because our user is often scared of new technology, because they don’t understand and use it.
-‐
Easy to remember how to use (memorability) The user should be able to use the product from memory once it has learned to use it, because we think the user doesn’t really
wants to learn new things.

4 Data Gathering
4.1Ethongraphic interview By discussing and combining our setups of or first ethnographic interview we combined these and made a list of questions for the ethnographic interview. With this we conducted our first pilot interview. The results of which can be seen in the appendix.
4.2 Interview
When composing the final interview we chose to make different categories In order to cover as much as possible relevant data about shopping habits, Health issues, preparation, actual shopping time, knowledge about technology, current level of satisfaction while shopping, Since the high variety of these question we were offered allot of information, As well as how the question where phrased. They where strict, thought open enough to start little conversations on the topic. This made that sometimes the gave more information than expected which enlightened features we didn’t even think about yet in that stage of the research. A second benefit we had related to the categories we had to interview, older people often intend to tell stories where they even compare to other time areas. Due the amount of information, the result of the interviews are included in the appendices.

4.3 Persona
The persona was directly conducted out of the information we gained from interviewing .
Background o 73-‐year-‐old o Female o Widow o 1 person household o Used to work in a sewing atelier o Has a small garden, her husband used to grow vegetables in it. o Adores her grand children. o Her husband died recently o To stay healthy is her main concern Characteristics o Happy o Trustful o Reliable o Religious o Loves traditions Customer Needs o correct ingredients o transparency o origin o Price/ quality o familiar historical o Reliable Louise is a typical dutch elderly. She still is in good condition due the exercise she gets by cycling to her friends and family. She lives near the city centre in the house she bought 50 Years ago together with her husband. Her husband unfortunately past away last year, due a hart attack. This makes that Louise now pays extra attention to her health. She feels she needs to be there for her children and grandchildren to grow up. Her husband used to grow vegetables in their garden, although she loved the idea of it , she doesn’t believe she can do it as good as he did. She and her children decided to turn the little conservatory into a flower garden. Students Jort Band s100824, Anouk Van Ranst s128835

5 Requirements a. functional requirement: Inform about product information with regard to allergies. So people can make the best possible decisions about their food. Should answer 80% of the diet related questions from the elderly who are using the product. b. Look and feel requirement: Look and feel should invite elderly to use it . (Low tech appearance) To lower the threshold to use to product. 60 % of elderly(who have never seen/heard of product before) should take the decision to pick the device up. c. Ease of use requirement: Making easier to understand product information To help elderly to make healthier decisions than when they don’t use the system. Double blind test: group1 of elderly who gets certain amount of products. Group2 gets same products but with the system. After using, group 2 should be 20% quicker in understanding the information than group 1. d. Ease of learning requirement: After first use the user should be familiar with the product. Avoid elderly people to not dare to use it again. (to not scare away) Give certain amount of elderly the system, 80% of this group should know how to use the product for the second time directly. e. Performance requirement: Product should run during the whole visit without interference, to avoid interrupting the shopping activity. 99,8% of the times elderly use the system, it has to work without interruptions during the visit to the supermarket.

6 Concept design
6.1 Scenario conclusion
Our product has two sides. First the registering part that a user has to do to actually use the product. But as our focus was more on the actually device and interaction that they were going to use in the store while registered, we have written a scenario for the actual use. The scenario is written with as user an elderly (65+) woman that already registered for the product. Scenario can be found in the appendices.
6.2 QOC Analysis Our QOC analysis was based on the question: How could the information (healthy/unhealthy, allergy info) about the product be displayed best for the user? To use the QOC analysis we came up with several ideas for the display. For all the ideas the user would scan the product and the following information would be displayed. The ideas can be found in the appendix. After that we had to set up some criteria for assessing these ideas. The list of criteria with motivation can be found in the appendix. Finally we had to assess the ideas; we did this by making a table with criteria on one side and the ideas on the other. You can see the table in the appendix. The List of text and the color display were very close together in score and also the two with the highest scores. So we thought we could combine the two. If we would combine the two we had the basic and direct information from the color display and the somewhat more elaborate text to see what is unhealthy about the product, so you trust that the design has made the right decisions for you.

6.3 Task Description
During the making of our paper prototype we had to make a task description for that paper prototype. In this we had to formulate on task that the user could perform with our prototype. The main goal or this task was to see if the user could make an appropriate choice with the information presented to them by our system. We also wanted to check if they know how to use the system and if they understand the information presented The following task was made. The following situation is sketched:” The user has to pretend that he or she has an allergy to nuts. The user wants to try pate. ” He or she then has to interact with the first price tag he or she encounters (in our case the AH- pate with nuts). After swiping the price tag, the price tag of the AH-Pate will turn red. Other alternatives will show up green. The user is then asked to pick a product.
6.4 Definitive concept development | System Since we believe in general approaches concerning health issues, We are convinced that our system should be available for everyone who is interested in using it regardless the supermarket you shop at ( highend supermarket to lower-class shops). We also believe that a country could benefit the use of this device, so we created a system regulated by the government for the first stage. system where you can enter your personal data The second stage of the system has to be implemented by the store, upon their personal choice.
Students Jort Band s100824, Anouk Van Ranst s128835

The first stage is a strictly personal one; provided by a general health service of the government. There is the possibility to upload personal information on the MY -NUTRITAG ( the card is loaded with your households personal info,) This can be don either by login on the website yourself or filling in a paper form. This form will offer some possibilities. o Synchronize your electronic patient dossier to make automatic healthy choices o Personal choices to avoid certain products/ ingredients o Personal diet plans by own initiative all info is personal adjustable MY-Nutritag is available in 2 forms ; anonymous and ID version. When using the anonymous card you cant log on to your electronical patient dossier due privacy reasons. When adjusting the info by web an authorization code is required to get access to the personal information. When using the paper form , you will have to sign to get authorization.
The second stage takes place in the supermarket. The supermarket installs the Nutritag on own expenses, this would mean that the system would be available in every layer of the market – low price up until exclusive. When introduced to the Nutritag the costumer receives his card and gets a basic explanation of how the system works. They also receive a link to a webadress, on this website they can practice at home if they want or get some more information on how to get the best out of the nutritag ( settings etc ) . After this the costumer is ready to enter the store to starts his/her grocery shopping. From now on the combination of use of the MY-nutritag and the nutritag for communal use will form the golden key towards healthy choses. Now some different scenario’s are possible The user swipes his/her personal card against a nutritag from a prduct out of the product range he/she wants. When healthy the nutritag wil lightup –green- , and so will 3 other products out of the same range but a different price range. Students Jort Band s100824, Anouk Van Ranst s128835

When the chosen product is unhealthy, but there are some healthy alternatives within the product range, again 3 options will show up by turning into a green colour. ( in 3 different price ranges ) The 3th situation , There is no healthy option for you in this product range, all products will turn red, a simple educative message wil show you why, when still not convinced you can click on exta to get more specific details. The 4 situation is even more unique, There is no healthy option, though th
its doesn’t do you to much harm when eating the product that showed a orange nutritag this one is the least bad for your health within this product range, it could be consumed with moderation. Visual explanation l

7 Evaluations Heuristic evaluation | possible errors Possible fatal errors could exist on very busy times, when people try to use the system at the same time for the same product with the same preferences. Although we like to consider that the age group we design for has intentions to shop during less busy moments, so they don’t feel the need to shop at the same speed as other age categories. (who intend to spend less time for shopping ). As a second improvement we enlarged the swipable area .
7.1 Prototype Why build the prototype as it is? What do we find out with this prototype. During the assignment, we had to make a paper prototype to test our design. During the process of making the prototype we changed our concept several times. We did this, because we had a lot of discussion about the final prototype trough the making of the paper prototype and the expert evaluation. Eventually we had our final product and made a final prototype for it. With this paper prototype we wanted to test if the user understood the design and to check if they could make healthy decisions based on the design. The result of this process can be found in the appendix, where you can see the description of the prototype, the prototype itself and a task description.

7.2 Expert Evaluation During the assignment we had to make an Interaction Problem Report IPR by doing an expert evaluation on our own design. This is the Result of the interaction Report. Help and documentation As of yet there is not a document of how the interaction with the system works or an obvious indication how to use it. Error prevention A user accidentally activates the wrong price tag. This could be caused of price tags being in close vicinity to each other. The user either waits a long time before activating a price tag or will scan the intended price tag immediately after. Cancel operation Once the price tag is activated the user has no option to deactivate the price tag. User tries to deactivate the price tag. When it doesn’t respond user feels out of control. Feedback User has to be sure the product has to be scanned. Sometimes lighting is hard to see, so users don’t know if they have activated the product. This may cause the user to spend too much time at the product to see if it is working. Saturation in products (too much information) Sometimes too much products can be good for you or too much products are recommended to you, because they are all healthy for you. People can’t see in the limited time which product they want to pick, so they have to use the system multiple times hindering other people to use it.

7.3 User Evaluation During our assignment we had to do a user test based upon a paper prototype. This user test had to be described according to the decide framework. This is a result thereof. The overall goal the evaluation addresses is: Find out if the user is able and willing to use the system. From this goal several questions followed: -‐
Does the user understand the prototype
-‐
How much explanation does the user need
-‐
Does the user find the system helpful
-‐
Does the user have any problems with the system
To answer these questions and achieve or goal we made several tasks for the user which can be found in the appendix. To do this test we had to come prepared. We had to print out the paper prototype and bring an explanatory text for the user, so that he or she could understand the basic working of the system, this text can be found in the appendix. It was also important to include an informed consent form, to ensure that the person, who participates in a user test, knows what he can expect and what his obligations are. You can find the informed consent form in the appendix. What we found in the test result was affirming to our design. The result of the user test can be found in the appendix. The user thought our system would be handy to use in a store and it would also let the user be guided in choice by the system. The user had no problem with using the prototype and selecting healthy food. Once a basic explanation was given to the user, the user could use the system without finding any troubles with it.

At last we would like to comfort our user with an extra service , Since we had the feeling they could still feel a bit uncertain if the nutritag was operating at that exact time for them , An extra security has been built in so there is no possibility of fatal health faults ( such as allergies,…) There for we have chosen to implement an extra frame which shows the first name of the user, so there is an extra human checkpoint before the user gets the product and buys it.
7.4 Conclusion During the assignment we had to use mainly two evaluation methods later in the design cycle; the user evaluation and the expert evaluation method. The expert evaluation method is really good in the respect that it looks at the product from a design perspective and dares to be critical about the design. User evaluation on the other hand is far less critical, it is more to check if the user understands a product and is able to use it as is intended. With this kind of method you only check if your assumptions were correct. The user will only provide limited feedback about the design itself. The user will always give feedback from his perspective of using the product. I think both ways of evaluation are valuable tools in the design cycle, but I think it is wise to start with the expert evaluation, because it has a critical view on your design and after that move to the user evaluation to check if your design functions in real life with the intended user.

8 Reflections
Reflection Jort Band
During the assignment I wanted to learn more about the competency User Focus and Perspective, because I felt I was lacking development in this competency area and I often had trouble integrating it in my projects. For this assignment we had weekly assignment that would end up in a report. The lectures served as a preparation of the assignments given that day. Within this assignment we didn’t only learn about various techniques used in used focused design, but we also learned how to approach a user focused design cycle. The techniques we learned were even more useful in context with the user focused design cycle. During the assignment I learned when various techniques should be used at what stage in the design cycle, to aid you in making cost and time efficient choices in this design cycle. I think using the techniques I learned throughout the design cycle will not only help me in a user centered design but also in design overall. During the assignment I also learned what the importance was of continuously self-assessing yourself and I learned about the tools to do it with. The involvement of users in the design process helps in various ways to come to a better design. When constantly assessing your design with a user mistakes are easily pointed out and can thus be corrected efficiently. Involving the user not only helps with assessing your design, but also the way you communicate your design. When you involve a user, you always have to explain your concept or idea to someone unfamiliar with it. This helps you in finding the key aspects of your idea or concept and helps you in communicating it towards the user in an understandable way. During this assignment I don’t think I have only gained more knowledge about the competency User Focus and perspective, but also in the competency Design and Research Processes. I also think that in a more general way I learned how to communicate my ideas and gained invaluable techniques for a designer. Techniques I will use in my upcoming projects.

Reflections by Anouk Van Ranst Regarding to my current status of pre-master I felt the necessity to participate to the class by some strong motivations. Equally important I would like to refer to them. Running trough the design cycle substantiated by facts and figures gained on a objective, scientifically correct way would be one of them. I believe this is the ‘spine’ of design on an academic level. How information was conducted and translated week by week taught me to not run to quickly trough the design. Week by week I was stunned by the new/extra and useful information we gained throughout that’s week assignment, and the variety to do this by all different approaches. It taught me to be patient and to stay objective as a researcher instead of rushing through the research process on assumptions. To continue until the exact wanted/needed information was obtained in order to complete the design. To really go into the field and interview the target group. It opened up my vision towards the importance of a close relationship with the user or being able to empathically relate to them by the use of persona’s. When the design process started It helped me allot to see things from their perspective. Staying self-critical and sharp was one of the tools to asses myself during the design process In order to complete it correctly. Nerveless working in a team and workgroup was a big advantage to this and to my personal development. The design benefitted the different visions and expert evaluations. When zooming out in order to see the bigger picture and reflecting on this assignment, I can state that I have succeeded to achieve my learning goals. I have grown as an academic researcher, I learned the basics of user focus perspective design and how to implement this new knowledge. To stay self critical and use the benefits of a constant assessment in combination with the advantage of working in a team. I also believe that I can use the gained knowledge for a global design approach. Using the design cycle to work more efficient in order to time and cost efficiency might offer a different/better perspective to future projects. Students Jort Band s100824, Anouk Van Ranst s128835

Persona Hypotheses Jort Elderly people
They often don’t use a lot of technology and are thus beginners on using new electronic devices. They want to use to product to achieve a healhy lifestyle and change their diet. They use it for personal use to see if they can try something new or if something is healthy or unhealthy for them. They need the product to be as simple as possible, because they don’t want to use complex electronical systems to search for the info. They usually go shopping several times a week for the groceries they need, probably in the near vicinity. Caretakers They are usually somewhat younger people, that use new technology more often, usually they are reasonably proficient with this new technology. Usually the caretaker is very much aware of what the elder can or cannot have. They often also have enough product knowledge to make the healthy decisions without the use of a device. They can do the shopping but usually aren’t there for that purpose but more to help people get up and take a shower etc. Family The family are usually more proficient in using new technology then the elderly people but their level of expertise varies from beginner to advanced users. They probably have a basic understanding of healthy food but aren’t experts in this. They usually want to the elderly of the family to eat healthy and help them stay healthy. They usually help the elderly of the family in grocery shopping and in various things around the house.

Mapping Assignment Jort
The mapping of changing the ringtone of my phone is I think quite good. Once you go into settings under the device tab you can click on sound options. Under this menu you can find the option to change your ringtone. I think this is good mapping, because you expect to find the option to change your ringtone under settings. After that there are a lot of options categorized in several different areas, one area is the options for your device where under you can see the option sound, which makes sense in the context of the rest of the menu. Finally it is really logical to find the change ringtone option under the sound menu of your device, because a ringtone is a sound that your device makes when it is called. So all in all I think the mapping is good and understandable. My mobile phone has a variety of ways to interact with it. Firstly the hardware pushbuttons, these are straightforward in what they do, you can push them and something happens. So the hardware button has really great affordance. One other way to interact with my phone is via touchscreen. You know you have to touch the device to be able to use it, because it feels the whole front side of the phone and the main interface is shown on the phone. Although it is very straightforward that you touch a touch screen, sometimes the affordance is not all that great, because of the multiple interactions you can do on a touchscreen. Usually it is pretty straight forward how to use the touch screen, for example typing a message. After clicking on where you want to type something a on screen keyboard appears so you can type the message by pressing the on screen buttons/keys. Sometimes it is not obvious if you have to; swipe, drag, tap or press something. This is why the general idea of the touch screen has good affordance, but that the affordance also heavily depends on the software written for it and the interaction with that software (interface). We were also asked to give some constraint of our mobile. -‐
Physical constraint You have to touch the screen to use the phone

-‐
Logical constraint You have to unlock the phone to use it.
-‐
Cultural constraint Are the icons used and obviously the language used in the phone?
During the assignment we also had to give an additional example of mapping, affordance and constraints from our daily environment. For this I choose a simple water cooker. Because the water cooker is a very straightforward device on which you only have to press one button and it starts to cook the water you have put into and turns itself off after it is done cooking. The mapping of the button to turn my water cooker on is obvious it is at the bottom and is coloured red, so you know that it has the functioned to turn the water cooker on and that the button is not used for example for opening the lid of the water cooker. The button of the water cooker to open the lid is in the centre of the lid, making the intended use of the button very obvious. So I would say the water cooker has a good mapping. Another thing is that the affordance of a water cooker is really good. The water cooker has 2 buttons and a stand that you can put it on to power it. The buttons look like buttons and can only go one way, although I have to admit that the black on black button located at the lid of the water cooker could be in a different colour, so that it is more obvious that it is a button, although that once you figured out it is a button it is no problem anymore. The water cooker has a lot of constraints. One logical physical constraint is that it has to be plugged in a power socket to work. A logical constraint of the water cooker is that it has to be put on the base before turning it on. Without doing this in the proper order the water cooker will not turn on. A cultural constraint is that the measuring of the amount of water in the water cooker is displayed in the metric system (parts of a litre).

GOAL | system that’s helps to select healthy food in supermarket, Includes/excludes certain ingredients or amounts of ingredients for specific and personal diets. Tagert group : Age-group 65 + anno 2013 Users could be the following people People with diet restrictions/wishes People With allergies People health conditions or drugs The product could be operated by ; Elderly people They often don’t use a lot of technology and are thus beginners on using new electronic devices. They want to use to product to achieve a healhy lifestyle and change their diet. They use it for personal use to see if they can try something new or if something is healthy or unhealthy for them. They need the product to be as simple as possible, because they don’t want to use complex electronical systems to search for the info. They usually go shopping several times a week for the groceries they need, probably in the near vicinity. Relatives Relatives help out allot in households of their elderly, certainly for tasks which are fiscally more demanding. Grocery shopping is one of them. Advantages of designing for this group would be there knowledge with technology and the correct use of it. Care takers They could use the system if it would also provide the option for multiple profiles. So they can adapt to the personal need of there individual clients.

does her normal groceries she comes across the new product she was thinking of buying. To check if it is healthy she gets her card out and presses it against the price tag. She sees that the price tag turns green with her name on it. She also sees 3 other price tags light up with a green glow that also have her name displayed on it. She sees that one of the green glowing price tags has a much cheaper price displayed on it. She takes the product with the cheapest price and goes on with her shopping. After she has al her groceries she goes to the register, pays and leaves the store as normal.
QOC Ideas List of text
See a list of a product when scanned where you can see all the requirements and if the product has those requirements. Color display Display a product with colors as good bad or medium/unhealthy, displayed as red green and orange lights. Buzzer The artifact buzzes when bad and gives a “pling” when good. Parking sensor Artifact beeps and the beeps go faster when something is bad for you (if lethal, continuous tone). Ik ben van mening dat wij deze er het beste uit kunnen laten. Plus Minus The more plusses the artifact gives the more the product is healthier for you, the more minuses it gives the unhealthier it is for you.

QOC  Criteria   Feasibility
We thought that feasibility was an important aspect to take into consideration, because later our design had to be implemented and for this reason it had to be feasible. Also the harder it is to implement a design the more the design will likely cost. Amount of information displayed The amount of information displayed was an important criterion, because the more information that is displayed about why a certain product is unhealthy or healthy for you the more you will trust the product to be correct. It also helps in creating a sense of control, because you can re asses what the product tells you. Accounting for old age (visibility and hearing) Because we are dealing with a user group of elderly people, they often have some impairments due to their age. This is why we have to take this into consideration in our design. Simplicity of information This is an important criterion, because we think that the users should understand the information that is presented to them, otherwise the information would be useless to the user. Personalizeability For us it was in some way important that the user could personalize the product in some respect. This would create a sort of emotional attachment to the product and would help making the information be personal and relevant to the user. Trustability For us it was also important that the user trusted the outcome of the device and the device itself. Because only then they will keep using the product and use it to make healthy decisions based on the output of the device.

Tasks for the User Test For the user test we had to think of ceveral tasks the users had to perform, with the use of our prototype. For this we designed three specific cases each one slightly different from the other. Task 1 Task one consisted of imagining that you were someone with a nut allergy. You come across AH-Rundvlees pate. The task is: find a suitable pate for you. Task 2 For this task imagine you are on a low sodium diet. You come across AH neutral flavored chips. Find the best chips for you. Task 3 For this task imagine that you just want to live healthy. You come across AH macaroni. The task is: compare the product and buy one.
Introduction for the User
The name of our system is the Nutritag. This system allows you to check if a product I healthy for you by swiping a personal card on the price tag of that product. When you do that you get immediate visual feedback trough the coloration of the price tag, even letting other price tags of the same product group light up so you can compare the products. Also if applicable
Top left product is scanned. It appears to be unhealthy but 3 healthy alternatives are presented to you.

Interview Annie Health issues
1 Met haar glutendieet vanwege glutenovergevoeligheid. Verder mag ze alles gewoon eten en let ze alleen een beetje op vet producten. 1b.
Haar darmen werken dan niet goed meer(diraree, buikpijn, verstopping), wat natuurlijk dan direct gevolgen heeft voor haar hele gezondheid, omdat je darmen dan geen belangrijke voedingsstoffen meer kan opnemen. 11. Waar zoekt u naar de juiste informatieve over IngrediĂŤnten/bestandsdeel als u een bepaald product nodig heeft ?
Op de verpakkingen staat vaak een icoontje voor glutenvrij product of er staat bij allergieinformatie of er gluten in kunnen voorkomen. 2b. Wat doet u als u deze informatie daar niet kan vinden?
Als het er niet staat en ze weet niet zeker of het glutenvrij is vraagt ze de verkopers. 2c. Heeft u eerder gebruik gemaakt van de informatie telefoonlijnen vermeld op de verpakkingen ?
Nee want alle producten die ze gebruikt hebben nog nooit problemen veroorzaakt. Ze zegt dat ze altijd wel kon beoordelen of een product mocht in het dieet. Preparation_________________________________________________________________________ ______ 12. Met betrekking tot uw gezondheid /dieet ; welke voorbereidingen treft u voorafgaand aan het winkelen ?
Ze checkt altijd gestructureerd of ze al haar nodige producten nog heeft in huis (want je kunt ook niet zomaar even bij de buren lenen, want daar zit waarschijnlijk wel overal gluten in) en maakt dan een boodschappenlijstje Shopping 13. Heeft u een vaste winkel routine 1b. Hoe ziet deze eruit ?
Niet bepaald, maar ze loopt natuurlijk wel altijd even langs de glutenvrije afdeling. 1c. besteed u betrekkelijk meer tijd in bepaalde delen van de winkel ?
De glutenvrije afdeling. (vaak in een rek met allerlei antiallergie, en natuurproducten) 14. beperkt uw dieet uw winkelkeuze ?

Nee. De meeste goede supermarkten hier in de buurt hebben allemaal wel wat glutenvrije producten. Het is niet heel denderend, maar als ik echt meer keuze wil, kan ik ook vaak terecht bij de natuurwinkel. Voldoet uw huidige winkel aan de behoefte van uw dieet ? 7.b met betrekking tot assortiment
Ja dus (zie vorige vraag). Hoewel het assortiment niet zo uitgebreid is, kan ik altijd alles vidnen wat ik nodig heb. Als ik eens een ander merk of soort wil, dan ga ik naar de natuur/ecowinkel omdat ze daar wat uitgebreider zijn. 7.c met betrekking tot informatie voorziening over producten
Gluten-allergie is veelvoorkomende allergie, dus in iedere supermarkt wordt goed aangegeven wat ze mag hebben op de verpakkingen. Zelfs als er sporen van gluten zouden kunnen voorkomen wordt dat vaak goed vermeld. 7.d met betrekking tot winkelindeling
Ik kom niet iedere keer in dezelfde winkel, maar veel producten staan gewoon tussen de schappen, omdat ik ook ‘gewoon’ producten mag hebben natuurlijk. Maar echt de speciale dingen zoals glutenvrij ‘brood’ staat vaak in aparte schappen bij de allergie/bio afdeling. Experience 15. Welke supermarktervaringen heeft u als vervelend /prettig bevonden mbt tot uw gezondheidsproblematiek?
Prettig: Toch wel dat ik er zelf makkelijk uit kan komen door die icoontjes. Vervelend: niet echt gehad. 16. Zijn er hulpmiddelen welke u gebruikt bij het boodschappen doen om u te helpen met het maken van bewuste keuzes?
De icoontjes op de verpakkingen, maar verder geen extra hulpmiddelen. 17. Hoe is uw ervaring met gadgets/apps in de supermarkt ?
Nooit gebruikt.
