Abstract

Kitchens are the heart of activity in any home. Today, a modern urban lifestyle, changing habits, communication technology etc has been transforming the face of present day Indian kitchens. This thesis aims at creating not just an interactive kitchen concept but takes an interactive design approach where in the users participate in defining and dictating the final product features.

A section of skilled urban population leads a highly migratory lifestyle. They transit places during education and career; following a trend continuing well into initial marital periods. A survey of this segment bought out the need for furniture which can move along with them and is reconfigurable i.e. modular furniture. Although the kitchen market is growing there are no products in market which can meet the specific demands of this significant urban migratory segment. Most of the kitchens today are fixed rigid structures rather than furniture. Majority of them being non-ergonomic, lack in organized storage and aesthetic compliment when compared to modern kitchen appliances.

The thesis starts with sensitizes itself to the basic concepts like kitchen planning, furniture design and interactive systems before defining proposal of concepts. It travels further to discover the users in terms of identifying his primary needs, dependence on technology during cooking etc. The final thesis output can be categorized into two segments. First segment creates a novel physical prototype for a modular mobile kitchen while the second segment explores concepts for an information centered kitchen environment for near future.

Chapter 1 / From Chulah to Microwave2

1.1 Introduction

Today the urban Indian homes today are modern in architecture, stocked with latest appliances and well attuned to change. In urban areas double-income nuclear families are becoming norm with considerable dispensable income flowing towards modern day furniture. As both male and female members are working it is hard to spend adequate time on elaborate cooking process. To save time and boot efficiency Indian kitchens are becoming organized and modern in outlook. Today, a wide range of food processing and cooking appliances are being brought by consumers who want to save on cooking time. Technology is changing the way we buy food, cook, and eat. We are witnessing a transition phase in face of Indian kitchens as they move from “Gas chulhas“ to microwave ovens.

Growth of service sector has created a large pool of skilled professionals in areas like IT, ITES, financial and other high growth areas. The current demography segment is highly migratory in lifestyle. This segment consists of educated, computer savvy professional users who are moving on a wave of economic growth. The users are cosmopolitan in outlook, aware of trends and have growing disposable incomes. Users in age group of 20 – 35 migrate across cities in search of better education and job opportunities. Married couples and professional bachelors although buy modular home furniture which they can move along when they shift are unable to furnish kitchens due to unavailability compact kitchen furniture’s offering mobility.

The author tries to address the above needs by proposing not just a product but a product category. The product category being a “smart mobile kitchen furniture” for urban India. While the proposed concept is for a “ mobile smart kitchen workstation “. A novel concept is developed and taken to physical prototyping level. The product may also find applications amongst other areas and segments.

(17)

The Design process started with a broad user survey using contextual interviews, observation of kitchens and cooking habits to understand user preferences, and requirements. Also studied was the impact of information and communication devices, technology inside cooking environment. Analysis and observations from survey led to drafting the design brief and specifications for guiding further creative exploration.

A number of concepts were generated during the process. Existing products in market were benchmarked for design. The final concept was chosen and detailed. A scaled prototype was developed and demonstrated in a design exhibition for review. Final iterations in design were carried before detailing final prototype. The thesis prototype aims at meeting primary and secondary goals. Primary goals were developing a mobile unit serving basic cooking activities with organized storage, a concept that offered flexibility in layout, elegance in design while being economical to user. Secondary goals were exploration of concept of smart kitchen and partial demonstration.

1.2 Changing Habits

Plate 1.0 Rural lady serving husband food in kitchen Plate 1.1 family having food on dining table Source - http://www.kamat.com/kalranga/food/indian_kitchen.htm

Kitchens in India are as varied in as Indian food and culture. Each kitchen is fine tuned towards meeting the needs of the local food preparation. A vast section of population is vegetarian. Cooking style depends on regional food type, community taste preference, weather, geography etc. Most of the Indian foods require elaborate pre processing. The food is spicy and concentration is on making food tastier and spicy. With modern food processing appliances in hand the task has become simpler for most of the urban ladies in kitchen. The Indian kitchens are reshaping today as cosmopolitan population embraces a modern consumption fueled lifestyle. The type of food that is consumed has also changed. Signs can be found in the popularity of packaged food like “Maggie noodles“ , or cornflakes being served to children for breakfast . Since urban life faces time crunch there is emphasis on food that can be cooked faster and needs least processing time.

In the past it was usual to see a wife serving food to family members inside the kitchen. The Dining space co exited inside kitchen space. A housewife would usually serve breakfast to husband before he left for work. Men and women rarely ate together in traditional households of India. Over the years with rise in standard of Indian living , has witnessed changing social habits and behaviors.

(19)

Urbanization and migration to cities for better opportunities has today led to breaking up of joint family structure creating nuclei family setups in urban areas. Today the family eats on a dining table instead of floor. For Couples working in ITES or call centers with conflicting work times most of the couples end up preparing and eating food alone. Today small urban families with both husband and wife working prefer not to waste much time on cooking and reserve maximum daily time for personal entertainment. Availability of pre processed packed food is becoming acceptable into daily diet in a time-crunched urban life. Children also prefer to eat fast food for breakfast or lunch, influenced by the media. Daily cooking can be a mundane daily activity for individuals. Hence a majority of them prefer to watch TV ,sms or use phone while cooking to get over the mundane. It was observed that some users had also changed the orientation of TV for better visibility from kitchens. ! Individual or family dining time today is unimaginable for some without entertainment through TV, Radio or music. Most of the ladies today try to schedule their daily cooking work so that they could catch up with their favorite shows

1.3 Defining the kitchen

A kitchen is a space used for food storage, preparation and cooking.

A modern kitchen is typically equipped with a gas fired stove or microwave oven for cooking. Refrigerator for food preservation and storage. Sink with water supply and draining for cleaning purpose of raw food and dishwashing. Organized storage in form of cupboards for food, utensils and any other aid resourceful during cooking.

Although the main function of a kitchen is cooking, it can be the center of other activities as well, especially within homes, depending on its size, furnishing, and equipment. If a washing machine is present, washing and drying laundry is also done in the kitchen. The kitchen may also be the place where the family eats, provided it is large enough. Sometimes, it is the most comforting room in a house, where family and visitors tend to congregate.

1.5 The Furniture Business in India -

A Case Study

Kitchen furniture is in great demand across all cities and towns. A survey in local market in Kanpur found modular kitchens were in demand across all segments. However a majority of kitchen manufacturers only cater to a very niche segment. Complete kitchen furniture available at starting average price of Rs 50000 and available till Rs 2.5 - 3 lakhs was being brought by consumers! Before moving ahead with defining new line of products it was necessary to understand the market as a whole .The following facts and figures are to give an overview of the furniture business in India. The case studies here have strongly reflected the need to push furniture design centered to address Indian needs to cope up with the surging demands.

In the area of decorative residential furniture, India has a heritage of exquisite handcrafted furniture, made out of teak, rosewood and walnut wood, which has strong colonial roots. The range of indigenous furniture available in India includes both residential and contract system furniture, with an increased concentration these days in office and kitchen furniture.

1.5.1 Indian Furniture Market :

Today the Indian furniture market1 is pegged at a value of INR 135 billion dollars of which 85% falls in the unorganized sector. The total addressable Market for Retail (All India Urban) for Furniture and Furnishing is INR 5,266 Crore. According to a market

survey on spending of disposable incomes among Indian consumers it was found that 38% were willing to invest in home improvements, furniture and 37 % in leisure holidays. Globalization has seen imported furniture make serious inroads into the Indian

markets. This has been awake up call for the manufacturing industry.

In furniture imports India ranked first from 1-1-04 to 15-7-05 importing 17 per cent of the total imports in furniture worldwide.

(24)

Furniture Import Value Growth

Wooden Kitchen Furniture INR 66 million 93%

Wooden Residential Furniture INR 56 million 40%

Fig 1.0. Indian Furniture Imports Source - http://www.ud.camcom.it/

The Indian furniture market is estimated to be worth Rs 350,000 million. Within this, the Wooden furniture accounts for Rs 60,000 million. Of this the imported furniture market is currently worth Rs 6000 million and is growing at 50 - 60% each year. The furniture sector in India only makes a marginal contribution to the GDP, representing about 0.5 percent of the total GDP.

2002004

1.5.2 Real Estate Overview of India

The real potential of furniture market can be assessed by reviewing the real estate growth. The growth of real estate and commercial properties is based on the overall growth of economy. The economy of the country since past few years has been bullish and will continue to be the same in the coming years. There has been the roundabout growth in all the sectors, be it manufacturing or service. The growth of the service sector which now constitutes more than the 50% of the GDP ( characteristic of a developed nation), is providing push to the realty sector in India. Constituent of the service sector are IT, ITeS, BPO’s, KPO’s, Hospitality industry, Retail, entertainment, Banking, Financial service providers, etc. Other important factor to be taken into account is the rising disposable incomes and increased consumer spending in India; which is again shaping the property markets in India. Average household income in urban areas has grown at a 5% Compounded Annual Growth Rate over the last decade. By 2010 the higher income earning group (>USD 2000) is expected to constitute 48% of the total earning population.

(25)

1.5.3 Social Indicator

India today boasts of 547 million strong populations that is below 25 years of age. The size of the market at Purchasing Power Parity (PPP) is estimated around US$ 1.5 trillion It also produces a large pool of educated professionals as under

• Over 3 million scientific & technical manpower

• Over 1 million graduate engineers and 0.4 million doctors and 0.8 million post graduates in science.

• 0.3 million graduates in agriculture and veterinary sciences.

• In addition 50,000 computer professionals and 360,000 engineering graduates each year.

1.5.4 Various Market Sizes based on the per capita expenditure

The average monthly per capita expenditure of urban Delhi in 2003 was INR 1,606. Tamil Nadu comes a second at INR 1,131, followed by Andhra Pradesh at INR 1,102. Gujarat, Punjab and Haryana are not very far behind, at INR 1,092, INR 1,059 and INR 1,050 respectively. At the bottom of the list is Uttar Pradesh at INR 827, Madhya Pradesh at INR 793 and Bihar at INR 784.

1.5.5 Population

Population evolution India’s population estimated at 1,055 million (2003) is expected to grow by 1.7% this year. Growing urbanization is a key trend in the country, with rural population growth averaging to 17.9% and urban growth at 30.7% for the period 1991 to 2001. Key statistics with regard to population growth and the urban and rural split are set out below.

(26)

Population Classification

Fig 1.2. Population classification Source - http://www.ud.camcom.it/

Over 70% of the urban population is estimated to reside in Class I cities (population of over one million). This is largely as a result of increased employment opportunities in cities as well as a preference among the younger generation to move away from agriculture.

(27)

1.5.6 Age Group

One of the important demographic trends in recent times is the changing age profile. India is increasingly being acknowledged as a “young” nation, with about 35% of its population less than 14 years of age. The median age of India’s population is 24 years. Youth are generally early adopters of most modern products and concepts. Given the higher aspirations and “willingness to change” of the younger age group, India’s age profile offers high market potential for consumer goods.

Fig 1.4. Ageing population Source - http://www.ud.camcom.it/3

1.5.7 Buying Power and Consumption.

The per capita income has been witnessing steady growth in the last few years .This trend is likely to continue in the near future as the economy continues to grow. As seen from the mapping of India’s income classes above, the consuming class and climbers’ class segments offer tremendous opportunity to the retailers. The number of households in these categories combined is expected to grow by 38.8% over the period 2005-2006. The lower income categories are projected to decline by 10.7%, while the very rich category is projected to double. Retailers will now focus on the consumption patterns of the middle class to map their future strategies, as this upward push will lead to greatly increased purchasing power. The trend in aggregate consumer spending also corroborates the consumption boom in the economy. The rate of growth of spending on discretionary items (unlike basic necessities like food) has been growing at an average of 9 per cent per year over the past five years. Significantly, the rate of growth has been recording a sharp spurt during the past two years.

2.1 General kitchen Space Planning Guidelines

Kitchens 2 should face North East or North West .Kitchens should be well located internally with respect to pantry, dining room and living. Although kitchens are small places there planning requires outmost attention to details. The kitchen are also places of meeting and have social significance .They occupy large amount of users time and peak attention periods. In residences Kitchens should be placed strategically for easy accessibility to all major work areas and rooms.

Fig 2.0. Kitchen function relation Source : Architects’ Data

2.2 Work Sequence

“ A place for everything, everything in place 3“ should be motto for a dream kitchen. In order to cut down walking distance between work centers, utensils should be stored where they need to be first. A well planned kitchen should not only look good but make the cook using it feel content with his place for work .Work centers and storage facilities to be laid out in order before freezing on the kitchen plan

When kitchen units are fitted they should follow a sequence which complements the work and reduces efforts. The structure should be spacious and allow room for free movement. The furniture should minimize standing work and any such posture which will be strenuous for the household person.

(30)

Ideal sequence of work in kitchen should be arranged in this order for a normal right handed person.

Storage - Cooking area - Preparation area – Draining area 2

For a left handed person sequence of operations is opposite.

(31)

17

2.3 Basic Kitchen Layouts

No one layout is more ideal than another. The room and interior character should itself dictate the design of an efficient kitchen layout. 3

Single Line kitchen

A very basic layout that should be kept as compact as possible. The cooker and sink must be kept closer in this layout

Fig 2.3. One sided kitchen Source : Architects’ Data : Plate 2.0 - Single line Kitchen plan Source : kitchen remodeling handbook

L Shaped kitchen

A work sequence runs around two walls, keeping work triangle reasonable compact. In a very small room it may be difficult to avoid placing refrigerator close to cooker, so not an ideal arrangement as refrigerator looses efficiency in cooling.

Fig 2.4 L kitchen Source : Architects’ Data : Plate 2.1 L Kitchen plan Source : kitchen remodeling handbook

(32)

18

Gallery Layout

Gallery kitchen have a compact work triangle than any of the arrangements so are less tiring in usage. Sink and cooker can be placed in opposite sides. This plan possesses least safety hazards.

Fig 2.5 Galley Kitchen Source : Architects’ Data : Plate 2.2 - Galley Kitchen plan Source : kitchen remodeling handbook

U shaped layout

This adaptable layout is wrapped around three walls in an unbroken sequence .This layout provides lots of work surface but the two corners would give some wasted space.

Island kitchen

This should be used in places where space is plentiful, if cooking activity involves lots of walking then work triangles are inconvenient in this case.

2.5 Minimum Area for kitchen planning

Cooking recess 5 - 6 m2

Normal kitchens 8 - 10 m2

kitchens with dinning 12 - 14 m2

Fig 2.7 –minimum area for kitchen planning Source : Architects handbook

Each work center in a kitchen should have three components. 2 1. Adequate work area on counter space

2. Adequate storage areas and volume

3. Sufficient access to facilities like ventilation, lighting ,drainage etc

2.6 Modular Furniture

Furniture definition: 5

The movable articles that are used to make a room or building suitable for living or working in, such as tables, chairs, or desks.

The cost difference between building a fixed furniture and movable furniture today is marginally and in some cases equivalent. A standard build up kitchen furniture has to be secured on to walls and flooring. The granite or marble counter is grouted on top of the furniture. On removal of furniture it results in damage to walls, floors that have to be repaired and painted. Since furniture is custom designed for space around it may not find significant usage later, overall a costly affair.

Movable furniture offer advantages, critical dimensions like height can be adjusted to suit user needs .They also offer flexibility in terms of easy assembly and disassembly before and after usage. Most of the movable furniture today use aluminum or magnesium alloy tubing that offer strength and are lightweight.

Mobile computer tables with wheels are quite popular today. These units offer flexibility of creating individual workstations for personal work/surfing or computer labs when clubbed together with similar units.

2.7 Standard Guidelines for kitchen Furniture Design

Materials 2 used in kitchen furniture include wood, plywood, chipboard, plastic, mild steel or stainless steel. Exposed wood surfaces are varnished or laminated with plastic. Shelves are of wood or plastic coated chipboard; metal shelves are best for pans and pots. Sliding or folding doors are useful if space is restricted requiring no additional space for opening. Special equipments like universal cutting board, pull out drawers, pull out towel rails, hinged compartments etc save time and effort. Sink and draining boards should be fitted into floor units which may include a waste bin, dishwasher and disposal units. Dishwashers to be fitted on the left or right side of sink

Different types of furniture in kitchen can be classified as

1. Base units or under counter units - These units are used for storing large, heavy or seldom used kitchen equipment.

2. Wall mounted units - Wall mounted have small depth so worktops beneath them can be used without hindrance. They allow crockery to be reached without bending

3. Tall units - Full height cupboards are suitable for storing cleaning materials, brooms etc. they can also house refrigerator or microwave

Chapter 3 / Human Factors & Kitchen Ergonomics 24

3.1 Overview

Ergonomics -

The word finds it roots from Greek, “ Ergo “ means work and “ nomos” which means law.

Ergonomics (or human factors) is the application of scientific information concerning humans to the design of objects, systems and environment for human use

(Definition adopted by the International Ergonomics Association in 2007).

Ergonomics 6 is concerned with design of systems in which people carry out work .All work systems consist of a human component and a machine component. Ergonomics aims to ensure the human needs for safe and efficient working are met in the design of work systems Ergonomics deals with design of efficient system. Basic Components of any systems are Man, Machine and Environment. A system could be simple or complex. A man and a machine is a simple ergo-system. A kitchen is a complex system, wherein man interacts with many machines in parallel in environment that is dynamic.

3.2 Need for Indian Anthropometric Data

Today7 a majority of products in market follow standards which are referred from American or European ergonomics standards. In case of furniture the case become of serious concern since we are talking about work efficiency, personal health over the usage cycle. Wrongly designed systems induce improper postures leading to operational uneasiness. Design of systems without due considerations to body dimensional requirements for intended users causes operational uneasiness, musculo-skeletal and sometimes physiological disorders.

Age, sex race and geographical regions7, even different occupations influence human body dimensions. From time to time, anthropometric data are generated amongst various populations in different countries and are used as ready references by designers. Experts suggest that anthropometric data to be used for specific groups should be based on same population groups.

Mass production has brought in standardization of products across various ranges. Factory made global products today are designed for global audience and offer very less flexibility, customization to users across. A bulk of furniture in Indian market fails to address the issue of designs confining to Indian anthropometric data. In the absence of indigenous design development in furniture and to stay competitive manufacturers often copy existing furniture designs and flood them in local market. Lately the trend of imported furniture has caught up in India. Again it must be asked how many of these products suit the Indian anthropometric dimensional requirement. Furniture designs without consideration for proper body dimensional requirement of intended users do not serve purpose and have less acceptance value.

Humans come in various shapes, sizes and so do they differ in habits, practices. Indian behavior also differs from western behavior; e.g. some Indians prefer sitting on floor for certain activities and perform a range of activities there. Design should be based on factors like user’s age, sex and postural considerations.

3.3 Kitchen Ergonomics

New Era kitchen design8 is a relatively recent discipline. The Initial concept to the work in the kitchen trace back to Catherine Beecher's A Treatise on Domestic Economy (1843) . The design included regular shelves on the walls, ample work space, and dedicated storage areas for various food items. Beecher's "model kitchen" propagated for the first time a systematic design based on early ergonomics. Beecher separated the functions of cooking and food preparation. He repositioned the stove into a compartment adjacent to the kitchen.

3.3.1 Frankfurt kitchen

Plate 3.0 – Frankfurt Kitchen 1 Source : http://en.wikipedia.org/wiki/Kitchen

The idea of efficient kitchen’s evolved from the much celebrated Frankfurt kitchen. Architect Christine Fredrick in 1927- 28 created the kitchen in a social housing project. The kitchen was analyzed following Taylorist principles using detailed time and motion studies which were published from 1913 in a series of articles on "New Household Management"

(43)

3.4 Kitchen Work Triangle

The idea of “ kitchen work triangle ”8 was formulated at the School of Architecture of the University of Illinois at Urbana-Champaign, founded in 1944 with aims at reducing cost through standardization.

Work triangle is simply an efficient arrangement of three major work points i.e cooking, refrigeration and sink. It is necessary to design arrangement which cuts down travelling distances of the user.

Chapter 4 / User survey and Research 32

4.1 Overview

User survey and research is necessary and one of the most important steps in product development cycle. Assessing the consumers’ behavior helps in finding the category where the need exists for products or services. Proper consumer research with supporting survey data as background is a norm of standard design activity these days. A proper survey helps in crisply defining a problem and henceforth generating relevant concepts for improvements .Understanding user requirements is the starting step of any design activity and is critical to the success of the end product. It is now widely understood that successful systems and products begin with an understanding of the needs and requirements of the users.

Consumer research helps in identifying the target user, his tastes his preference, his habit, culture, style etc. A designer should understand the user and his priorities in order to design products that hold meaning for the directed consumers. A consumer research tells about which ideas or concepts evolved by management are worth pursuing till final stages by paying attention to consumer choices.

The Author’s user research was carried in following parts • In-depth personal interviews and contextual enquiry • Visit to kitchens and observing users perform functions • Online surveys to targeted respondents.

Aims an objectives of User survey

• To gather quantitative and qualitative data

• Gain insight into user’s priorities, work flow in kitchen, there requirements. • Identify the need for a smart kitchen

• Understand role of interactivity between users, communication - entertainment devices, inside the modern kitchen space.

(47)

4.2 Qualitative and Quantitative survey

4.2.1 Qualitative Research survey

Qualitative research 9 is used for a small number of respondent group to get an insight into users psychology, behavior, needs, problems etc. A technique of in-depth interview is carried out with users in their work environment. The observations and interview is usually carried out in a relaxed mood so that users are comfortable talking and sharing experiences on subject area

.

4.2.2 Quantitative Research Survey

A Quantitative marketing research is used to get information on questions which cannot be answered in yes or no. It is used to draw conclusions, tests a specific hypothesis - uses random sampling techniques so as to infer from the sample to the population - involves a large number of respondents through survey and questionnaire.

4.3 Contextual Interview

A contextual interview, involves watching and observing subjects closely as they perform their intended tasks .Questions are asked only to clarify doubts whenever they arise and are required to get deeper insights. Users are encouraged to work in a natural way and not be influence by the interviewer’s presence or questions. The results are usually qualitative rather than quantitative

The study started with visit to homes of consumers in the selected consumer segment . A total of 15 homes of audience varied in income, education and location were studied in around Kanpur city, SBRA hostels of Indian Institute of Technology, Kanpur campus. The campus provided a large set of target population that was migratory in nature The process involved selecting the users, getting prior appointments, visiting them and interviewing them. The author tries to get a deep insight into understanding the subjects, their problems, their needs by a creating casual atmosphere

4.7.5 User inputs and suggestions

Documented are the inputs entered by users on online survey form.

a) Product Features and Cooking Experience

- It would be of value if you can make it light to carry away parts to be useful for transferable people

- A sketching board

- Where I can tag daily menu

- The whole feature may be able to rotate. - A bed with an attached make up table

- Dish washer, garbage dryer (it dries your all type of garbage once u put them in that machine)

- Color changing refrigerator

- All in one type’s equipments...make it one...Toaster, griller, micro wave, gas, blender chopper etc rather make portable equipment that serves as a kitchen. Keep it

anywhere. - Free delivery

- Auto pilot, no need to be in kitchen may be remote controlled, from me on sofa in front of TV in leaving room.

(62)

- Kitchen that cooks also.

- It should cook on its own as soon as I am hungry... - A display area for my family pics.

- A small interesting sitting space near window from where i can take a look of outside. - A display touch screen which has the cabin ate number and the list of material in cabinet

- Adjustable height chair to take all short women to all levels and reach all heights of cupboards.

- A video chat station and web cam surveillance.

- Often seasoning or garnishing makes all the difference so something that can do the garnishing\seasoning according to ones' personal tastes (may be this can be

programmed based on the users' needs)

- The cooking triangle should be properly incorporated in the design.

- Timed burner like washing machine so that u can time it for increasing or lowering the flame and turn off automatically. Also would prefer a rack for drying utensils

- A refrigerator that warns about food going bad..

- Nothing futuristic but only if someone could design an affordable dishwasher... hate washing the utensils, but don’t want to spend several grands on a regular dishwasher. - Robo-assistant/chef, who can keep track of my needs with respect to food and other ternary in kitchen.

- A fridge that scans the expiry date of products and orders replacements through the internet online as and when stock runs out or expires.

- Washing utensils is boring, I would have a conveyor from the sink directly to a vessel washing machine and later collect the washed vessels and arrange them back..and adjustable sink height...

- A gas stove burner on the top of the sink, or a pull out sink below the burner. Freedom to use the burner from both sides of the slab (stove that can be rotated- as for me i usually dream to have everything electrical ... handy, compact stuff should be there like electric hotpot, roaster, griller, fryer.

(63)

- Child safe kitchen, food burning detector, auto switch off gas if it is not burning.- -A wine vending machine/ draft beer fountains

- have washing machine attached. so that clothes clean up while cooking is going on, u know one kitchen n all done.

- Auto turn off feature with gas burner and heater. - Computerized conveyor belt kitchen system

- feed in the raw materials, & type in the specifications of the food u want

- The raw stuff will pass thru different stages (washing/chopping/ steam/ frying etc) similar to that on a conveyor belt & delivering the cooked food at the end

- Self-cleaning kitchen!

- Most of the world are turning towards dieting, so maybe something showing the intake of calories and maybe showing some menu and how to make them as a recipe.. Maybe like your internet facility but much more modern not just like fixing any tv or lcd panel on your cabinet maybe something which is voice directed and activated..

- you should check out the universal kitchen project done about 8 years ago by RISD shown at the Cooper Hewitt design museum in NYC- Intelligent storage system that would let me know, in advance, the grocery item is about to finish. Let’s say my refrigerator has fixed space for particular product (or maybe we can program it accordingly) then that will let me know when the milk is about to finish... same is with other storage like racks and drawers..when there are not many items in the kitchen, we really don’t need this.... but as i m experiencing now a days... when there are lots of items in your kitchen, then the suggested idea could be of great help.

- I would like have a microwave, oven, dish washer. - Automatic temperature and smoke regulator

- To set this device apart from other appliances even more, the chief focus should be design. Use of quality materials, careful manufacturing, and contemporary styling would make it more expensive but more notable.

- Easily adjustable slab height according to the person’s height. - Kitchen in a suitcase, collapsible tent kitchen

(64)

- Machines to help in cutting and cleaning

- programmed kitchen for food. Like you enter food code and the required material for the recipe will get ready like masala etc. then you will have to just cook,

- would love to have automated cooking machine ;)- a sitting arrangement...for one person who want to chat with me during cooking an area to keep beer making operation of all kitchen appliances through one single computer, cooking food without entering the kitchen, just by typing few keys on my computers keyboard. - Love if my food never gets over cooked or burned...and milk never spills... - May be a Portable kitchen, which i can carry when i go to picnic to cook food for myself and my friends.

- An appliance that selects vegetables and spices from the given recipe, processes those, cooks and serves and applies own intelligence gives some value added inputs (when required) while cooking...

- Maybe a robot!

- I m a gizmo freak any addition of such things would surely fascinate me..It’s a personal choice

b) Information/communication devices in kitchen

-I want my whole concentration on one side other both will be messed up but it is a nice idea

- Not too futuristic, a tv might be nice :)

- All this will not be much relevant because young people do not spend much time in kitchen

- Kitchen is directly related to higher than comfortable temperature, and i won't like to do any other attention seeking activity there...

- I will prefer doing most possible kitchen activities in normal comfortable conditions and postures, i.e. out of kitchen instead of bringing comfort in small kitchen area.

(65)

- No, Sounds TOO futuristic.- I have a small concern though is it safe to be multitasking like this when u r using a gas stove or other appliances in the kitchen.

- I feel i don’t need any display in kitchen as i already plan to have a computer in my bedroom, and a additi0onal laptop. I can carry laptop to my kitchen if I am so desperate to cook..

- Cost must be justified.. Moreover a dedicated computer in the kitchen just for finding a recipe is not justified cost wise

- Yes it is possible if it is really affordable.

- Multi-tasking is often a necessary evil in professional life, so I'd rather avoid it at home. Moreover, it's better to keep life simple!

- While cooking i really enjoy it and I think I’ll make time with these appliances once the food is ready and in my plate.

- Not as much futuristic as simply unnecessary; it would seem more so as a distraction. However, to refine on the idea: A device that could be hidden away and/or telescope and rotate would be nice (like an LCD on a VESA mount).

- i use computer for different purposes, kitchen can come to my computer, but computer can't go to kitchen.

- While cooking one can’t do multiple activities. Its needs attention. Computers, internet, phone can go with it. Well Music and TV does gel well with cooking

4.8 Key Deductions From User Survey

Some of the important key points noted from survey that would be used for guiding creative exploration of concepts to be generated are as follows

• A kitchen plan that is flexible with there requirements

• Kitchen counters need to be height adjustable i.e. provide ergonomic comfort • Furniture should be able to accommodate existing appliances.

• Furniture that was not fixed or partially fixed to allow mobility.

• Aesthetic, trendy in style furniture is as high on priority list as function of the furniture for ladies.

• There is a demand for a compact kitchen workstation.

• Need for a modern and organized kitchen furniture that is affordable. Option to pay in instalment or buy complete product in modules .

• Information display and interactive component was not immediate requirement since usage was not very frequent however many expressed desire for the system in the future.

• Interactive component should be user friendly , should not create excessive multitasking which could endanger kitchen work.

• Interaction between user and all smart appliances, systems should be centralized. And follow on lines idea like “one remote for all” .Interfaces should be mobile and dynamic ad move with the user in his workspace space

• Price range for modular furniture was in range of Rs 15000 - 20000 And with complete appliances not more than Rs 40,000

5.1 INTELLIGENT KITCHEN

Leonardo da Vinci invented an automated system for a rotating spit for spit-roasting 3 : a propeller in the chimney made the spit turn all by itself. The system widely used initially in wealthier homes later became a standard for all kitchens in coming ages. This could be sated as the first demonstration of the first “smart kitchen “ in history.

Plate 5.0 : Humanoid robot ARMAR Source - wwwiaim.ira.uka.de/users/asfour/armar/

Today an array of electrical appliances, devices and tools can be found in the kitchen and around. The common factor amongst is that they are microprocessor based. They are smart in terms of they use need less energy, are more flexible, solve their tasks more skillfully, and show in the results better capability characteristics. We cans say they are intelligent If they can automatically switch on their power supply at the time of need , or can automatically vary the self control there processing based on sensors. Today many of these devices and appliances can be remotely controlled by users and are able to communicate by means of alarms, glowing LEDs or vibrations. In the near future we should see integration of all these independent appliance controls onto a common platform. A universal centralized control for all function. The control system would be a common platform for physical and software interface between man and intelligent appliances, hence increasing comfort and efficiency. The kitchen of future might boost of a centralized control system.
