3 I. Agree on our goals (usability, experience and others) In order to find the users groups, we have based our users search on finding the users of a kitchen, but also the users of technology. By crossing these two groups and adding users who need more efficiency because they don t have the time to spend hours for cooking, we finally get two main groups we would like to focus on: Teenagers who are connected and who start to cook by themselves at home. They don t want to leave their MP3 player or they run between the TV and the pans every minute. Adults, men and women, who have their personal kitchen at home, who spend enough time in the kitchen to deserve a better experience than the extractor hood noise or the microwave ringing. They probably like listening to music, hearing the news, finding a new recipe and piloting all kitchen equipments like a conductor during a great concert. As everyday users of technology and safety-concerned persons, users need the product to meet these requirements: Easy to use, easy to remember, Connectivity, Not usable by kids, At-a-glance manageable. So, to match these needs, we have chosen the most important characteristics our product must have: Tablet, integrable into a kitchen near the cooking plates. Small, around the size of an adult stretched hand, so that it is easily integrable. Connected to Internet, with a web interface and synchronized to a smartphone so that you can pre-heat the oven or make sure everything s fine. Capacitive screen technology, which reacts very well and only to human contact, and not to kitchen accessories. Hand-size recognition to prevent its use by children; possibility to unlock it remotely with the web interface or the smartphone interface. Connected to the cooking plates, the microwave oven, the oven and the extraction hood (number of them is manageable); and possibility to add functionalities like coffee-maker timer. Use of icons, so it s visual and you can see quite fast if something is on. Multi-tasks. Virtual keyboard, to annotate and write recipes; stylus would be the best, but stylus on capacitive screens are not satisfying now (you can t write well with them). HCI 2010 Page 3 on 10

4 II. Data collection and analysis In order to collect data from users, we made an online survey we promoted via our blog, Facebook and Twitter. You can see the results below. If you answer other to the previous question, what do you do? Talk on the phone HCI 2010 Page 4 on 10

These results are interesting because here we are providing two functionalities that are not so different because both can be seen as very convenient.

So we have looked to the differences and it appears that the first one is active, you turn something on which is going to start running with you, contrary to the other one, which is passive, you just

Besides, this result shows that people are heavily concerned with safety.

5 These results are interesting because here we are providing two functionalities that are not so different because both can be seen as very convenient. But if you look at the result, the first one is rejected by people whereas the other one is approved with a huge majority. So we have looked to the differences and it appears that the first one is active, you turn something on which is going to start running with you, contrary to the other one, which is passive, you just have access to some information but you control everything. So we can deduce that people let the technology to help them but they absolutely want to keep control over things. Besides, this result shows that people are heavily concerned with safety. It explains the previous results which are that they don t want to let a computer to manage dangerous things as a oven without controlling it. Here we can see that the results are distributed between the three answers so, as it is never possible to make everyone happy, we deduced that there is no big mistake. Here we have a kind of confirmation of our deduction because we see that most of the people like what we have planed, even if they don t use all of them every day. HCI 2010 Page 5 on 10

6 People all agree to say that nowadays smartphones synchronization is at least useful, or else essential. A huge majority finally feels that bringing technology in the kitchen would make their cooking experience nicer. III. Evaluation of our idea The data collected reveal a great interest in this kind of kitchen control panel because, as we had assumed, many people used to do a lot of things while they are cooking. So that, by making their activities easier, it would make their cooking experience better and safer. Very few people want less functionality and some want more. But as it was an Internet questionnaire that we ve promoted to our friends, people who answered are like us very interested in new technologies, so we can deduce that the average people get what they want with the functionalities we ve chosen. People would love a connected kitchen and some applications as the synchronization of their cooking list on their smartphone had a great success. Nevertheless, it appears that even if computers make their life better, people don t have an entire trust about them, so they suggest us to think of integrating a manual command that can supply the computer if bugs occur or in case of emergency. People like almost all the prototype we planned, except one or two things, so we can say that we have planned quite well the needs of users, and we are going to improve it by listening to users recommendations to make a prototype that really meets users expectations.

7 IV. Alternatives & prototypes 1. Multitouch interface This interface is very similar to a smartphone one so very intuitive and people already know how to use it. The menus are accessible directly in the 1 st page and multimedia functionalities easily accessible in another interface you can slide down and up to open and hide it. Security is performed via hand-size recognition. 2. Computer interface HCI 2010 Page 7 on 10

It allows users to not make any changes in their kitchen, but provide distance-management thanks to domotic plugs. The security is performed via password. 3.

8 It allows users to not make any changes in their kitchen, but provide distance-management thanks to domotic plugs. The security is performed via password. 3. Vocal interface If you have dirty hands or you are holding something you can control your kitchen with your voice. You switch between the different screens by vocal command or with little buttons. The security is performed via vocal recognition. V. Evaluation of the prototypes and final decision The computer interface needs a computer in the kitchen and the use of clean and precise hands. To be efficient you ll need 2 hands to type on the keyboard and go and find your windows with the touch pad is not very quick and convenient. The vocal interface can be annoying by speaking each time you should be warned of something (hot oven, end of cooking time, etc.). You also need to memorize all the vocal commands used in the interface management. Besides you have to record the voice of every people who may you the kitchen. Whereas the multitouch interface is efficient, you only need one hand to use it. The hand-size recognition allows you to register a minimum size to prevent kids from using dangerous materials but not every hand in the family. You can easily switch between fun and cooking functionalities. The interface is very simple and each functionality is accessible in the 1 st page. So with 1 click you get into its parameters and with another click to go back. That s why we have chosen to go on working with the multitouch interface because it is well adapted to an efficient cooking use. But, according to suggestions we had in our survey, we plan to integrate very few vocal commands as an alternative if you can t use your hands. HCI 2010 Page 8 on 10

9 VI. Literature collection Sociable Kitchen: Interactive Recipe System in Kitchen Island (International Journal of Smart Home Vol.3, No.2, April, 2009) This article brings the idea that we don t only have to create technological functionalities to improve cooking activities, but we have to pay attention to social interactions in the kitchen and focus on developing functionalities that increase the share of emotions and the communication between people. Touch Gesture Reference Guide by LukeW LukeW is an internationally recognized digital product design who has written many articles about human interaction, web design but also mobile and multitouch design. This guide is a reference of every kind of gestures which can be used on a multitouch interface. So we ll take inspiration of that in order to create the best navigation menus as possible. Smart home hacks by Gordon Meyer Chap. Kitchen and Bath This book of 2005 shows that it has been quite long time that people have started thinking about the way of making a house smart. In this book you ll find some tips and DIY way of making your home smarter with the technologies of So, from now, it is interesting to see their try, and their reflexion about all the functionalities that can be useful and make people s cooking experience nicer. A lot of these ideas can be taken again and we ll think of adding them in an improving list for our prototype. 0C&printsec=frontcover&hl=fr#v=onepage&q&f=false Today's "Kitchen of Tomorrow" by Paul Lukas This article is about an interesting reflexion that shows that in the 50s people have imagined crazy technologicalcooking stuff and kitchen things for their time, but now we have enough skill in technology, none of them have been created for real, contrary to planes, cars or computers fields which have developed amazing capabilities.it also shows that the important thing is that, no matter what technology we can create, its first goal is to preveserve the domestic values. It is another kind of approach and will remind us to not create functionalities that separate people but which bring to family together. HCI 2010 Page 9 on 10

In the kitchen you have a screen where people can login on a website and control the electric system. This system also provides visitor identification and a fingerprint reader.

So, it s up to us to improve it and propose a better multitouch interface. http://www.avivre.net/maisonastudiob/diapocuis.shtml http://www.avivre.net/maisonastudiob/images/presseweb/home.

10 Maison A studio B (a showroom house in Paris) Its website and all the articles about that house are in French, but we thought that it was really interesting because it is a real showroom which can be visited in Paris where all the actual smart home technologies have been installed and can be tested by people. In the kitchen you have a screen where people can login on a website and control the electric system. This system also provides visitor identification and a fingerprint reader. This article is a state of the art of the existing technologies and how we can integrate them in a real house. So, it s up to us to improve it and propose a better multitouch interface.
