    Products specially designed for elderly is con-sidered a growing market and an area in which countless challenges and possibilities exists for creating good interaction design. The scope of this project includes conceptualiza-tion, mock-ups and testing a design aimed to help elderly in their daily life.

    This phase of the project gives an outline of the concept GoodFood, supported by research and interaction tools gathered through DTU course 42072: Design for Interaction. The concept has, so far, been developed through a creative process including brainstorming and selection. The first idea generation based on a brainstorm over the four themes; Independ-ent Living, Health and Care, Occupation and Recreation, gave a number of ideas showing concentrations in Independent Living and Health and Care. Developing the ideas fur-ther, choosing the most interesting, based on assumed relevancy and evaluation of feasibil-ity, focused the project on providing elderly a help to ensure correct and varied nutrition.

    DxI for Elderly

  • What is theproblem?

  • 8Interaction Magazine

    Elderly tends to have a monotonous diet driv-en by habits. This can result in wrong nutri-tion, ultimately leading to life-style-diseases or malnutrition[DR]. As many as 55% of elderly finds it difficult simply to distinguish healthy form unhealthy food [ldresagen]. Malnutri-tion can also be a result of not having the en-ergy to shop, reduced digestion or ability to chew.

    When people age, their appetite regulation gets less sensitive. Thereby the food consump-tion does not automatically adjust to the en-ergy demand. Often this will result in weight loss. Apart from the less functioning appetite regulation, there are several other causes to a reduced appetite e.g. psychological or social reasons such as depression, social isolation, bad teeth, and affected taste and smell senses.[meraadet]

    The problem of not getting the correct nutri-tion can be of special importance if a sud-den demand arises e.g. in case of high blood pressure, obesity or diabetes. Further, reduced physical ability can limit the possibilities of a varied diet.

    The GoodFood conceptThe GoodFood concept is a cooking helper for elderly people to help them maintain a var-ied diet together with providing instructions and tips for cooking. GoodFood is realised as an application for tablets and will be accessi-ble by download through different app stores.

    The application will assist the users in creat-ing weekly menus as well as drawing up shop-ping lists with the needed ingredients. The shopping list can be printed, texted or directly synchronised to a smartphone. If the mood/possibilities for shopping is not present, it is possible to order the ingredients through the application. Through user registration upon purchase, various possibilities for personalisa-tion will be available e.g. bookmarking of reci-pes and long term dietary guidance.The weekly menus are based on general nutri-tional guidelines tailored for the elderly gener-ation. If necessary, specific dietary needs (e.g. allergies and dislikes) can easily be input and considered when suggestions for the menu are presented. Nutritional information on the different meals will be visually presented and explained for the user, to make them under-stand why it is good for them and what the different proteins, vitamins, fibres etc. do. Other than putting together delicious and var-ied menus, the app will also provide cooking tips and instructions through videos, illustra-tions and audio.

    It is important to note that the application will not be designed to act as a wag of the finger

    to the user as this often result in unwillingness of use. Instead it is created to assist the user in obtaining a varied, nutritious and delicious diet through user inputs and user-based sug-gestions.

    Due to hygienic reasons the medium for in-teraction is important. Currently add-on de-vices/docking and voice control has been considered.

    ValidationThe concept outline was discussed with pos-sible users and the general feedback was posi-tive. They liked the possibility to plan meals for a whole week and be able to order ingredi-ents directly though the app. A user expressed that she really often found it hard to get inspi-ration for new menus etc. and would really like an assistant. Another positive point, was the feature about avoiding certain ingredients e.g. in relation to medicine use. One was taking anticoagulant medication, not allowing him to eat food with a high content of k-vitamin. His wife, who cooks the most, said it would be nice to get inspiration how to make new reci-pes. Especially when it comes to vegetables, because a lot of the vegetables they used to eat before has a high k-vitamin content, e.g. spinach.

    Some general comments, which will be con-sidered for next phase of the project, were concerning; price for both the app and price level of week plan and hygiene.

    The usersGoodFood is designed/intended for users aged 65 and above, but could easily be altered to fit with younger people as well. The target-ed user group are able to cook for themselves but do not necessarily need to be in shape for shopping as the application allows for online ordering of goods. The application is not spe-cially directed at singles or elderly with special dietary needs, but can be used by everybody that wants inspiration and tips for a varied and interesting diet. GoodFood, as explained in previous para-graph, is designed as a tablet application and intended for the upcoming retirees. Due to the general increase in use of tablets and smartphones it is assumed that the upcoming pensioners will know how to use touch screen products. Furthermore it is expected that many already own either a tablet or smartphone and that even more have plans on acquiring one.

    To get a better understanding of the user group, personas have been made on the basis of the research (see page 17).

    Persona 1 Elderly couple: Age 67 and 65 Curios on different food sources Physically able to cook and buy ingredients Are currently eating healthy Like cooking and trying different tastes

    Persona 2 Age: 72 People with special demands for their food (nutrition values) Physically able to cook and buy ingredients

    Persona 3 Age: 75 Special physical need. Is not able to bent to use the oven Orders food ingredients through an e-shop

    Persona 4 Age: 84 Normally uses cooking books to find recipes Physically able to cook and buy ingredients

    Use contextThe GoodFood application is installed on a tablet, which means it can actually be used everywhere. However it is assumed that eld-erly will use it primarily at home. The applica-tion has different characteristics that affords different use contexts. When planning the weekly menu together with creating shopping lists for what to buy or simply browsing reci-pes and information on nutritional contents of meals, it is expected that user will be sitting in their living room in a comfortable chair. In this case the regular touch screen is the tangi-ble interface.

    Another dimension is when the application is used in the kitchen during the cooking session. In this case the physical interaction becomes interesting, as kitchen hygiene is an unavoid-able and important issue. In the kitchen envi-ronment, the tablet is exposed to hazardous elements as e.g. water and bacteria when the user has to interact with the tablet. But also when turning the scenario around other is-sues appear. Bearing in mind that the tablet can be used for many things e.g. gaming while on the go or in the bathroom, the problem of the tablet bringing outside bacterias into the kitchen is also necessary to keep in mind when designing the physical interaction. A solution for this has not currently been developed, however suggestions for add-on products as e.g. docks, remote controllers or covers have been considered. The final solution will be presented in the next report.

    Interacting withGoodFoodThe first time the user uses GoodFood, he/she will have to register. During the registra-tion the user has the possibility to personalize the application specifically to their wishes and potential dietary needs. The type of informa-tion which could be asked to supply by the user could be:

    General personal information e.g. sex, age, height and weight Allergies or intolerance towards certain foods or ingredients Likes and dislikes of e.g. food and spices Known favourite recipes Medical history or current illnesses Use of medication Experience in the kitchen Etc.
