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.

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.

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.

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.

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.


11

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.


12

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.

Fig 1.3. Population growth Source - http://www.ud.camcom.it/3


13

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.

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

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.

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.


21

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

Human Factors &

Kitchen Ergonomics

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.

dimensions of designed prototype

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"


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

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.


33

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

User profile - Sex

Fig 4.11 : Survey Statistics 12

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.


48

- 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.


49

- 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


50

- 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 glasses/bottles-

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.

- Control should never be so centralized...creates problems always..


51

- 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% of total

population)

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.


55

5.2 Designing the Man Machine interface The kitchen is heart of activity and require constant attention When we talk about

making a smart kitchen we should consider making activities noticeable to people.

Addition of interfaces increases complexity of interaction between space and users. Smart interaction mapping should be as natural as commonsense 6 .

While designing a man machine interface it is necessary for us to consider important

aspects of cognition. The proposal should start with raising questions like; through

which sense is information conveyed? What mechanism? Is it active or passive? Does it

adhere to ergonomic norms?

Plate 5.1 : Interfaces in kitchen

Source Bonanni, L., Lee, C.H., and Selker, T. "Attention-Based Design of Augmented Reality Interfaces." Short paper in proceedings of Computer Human Interaction (CHI) 2005, Portland 5.2.1 Choice of channel Voice based interaction or Display based interaction? Visual signals6 are able to convey a large range of diverse information and are

commonly used. Auditory signals are appropriate for warning signals, to attract attention

or transmit information to person who is occupied in other work. While designing the

interface between the smart kitchen and user it would have to be underlined the channel

of interaction for specific task. Interactivity should not become a distracting or


56

dangerous to primary function or task i.e. cooking. The channel of interaction could be

mixture of audio and video.

Cooking tasks require continuous attention; also the activities inside kitchen require

constant motion for the user to reach out to appliances or storage areas. Adding a fixed

display would increase the complexity of this ergo system. Therefore it becomes

important that the interaction platform moves with the user rather than the user

approaching display terminals. Virtual projection technology under development would

make this kind of interaction practical. Three dimensional representation of information

in free space using holographic projections is ideal for kitchen environments. Virtual

interface would allow information to pop up on user commands anywhere in 3d space.

Information could also be projected on 2d

space

Plate 5.2 : Virtual keyboard

http://www.webopedia.com/FIG/virtual_keyboard.jpg

The User survey carried out by the author points out a popular opinion from people

against a visual display terminal inside kitchen. Some respondents perceived it as a

source of distraction to cooking work. However this should not be taken as a valid

conclusion as the user does not always know what is right beforehand and may find

service useful when exposed to it. The kitchen can be a dangerous place as it requires

uttermost attention during complex cooking and preparation process. Respondents

were open to idea of voice based communication and entertainment system. This fact is

supported by the reason why most of the people listened to music or news on TV, radio,

or music players while cooking. It was entertaining as well as non-distracting as the

kitchen work was being carried out.

Plate 5.3 : Concept of a compact interactive kitchen Source : Author

5.3 Proposed Functions Of Smart kitchen

• Act as a centralized console for interface and control over all appliance and functions. Also allow users to communicate and entertain themselves.

• Keep a stock of position of all food products and inform the user on his cell phone, laptop or an auditory command when required.

• Idea user interface should be mobile, i.e. the display should appear wherever the user wants it. Holographic projections

• Diet manger- future kitchens should be able to monitor the user’s health and daily food intake. This is possible through using Wi-Fi and RFID technology.

• Monitor energy, fuel and resource consumptions of systems like electricity, heating, lighting etc. Maintain the most efficient and energy saving conditions.

• Allow users to access internet and search for recipes.

• Intelligent and self learning system. Get tuned to user habits and preference with usage.

• Connectivity to webcams in home allowing users to monitor entire home from kitchen.


58

5.4 RFID Applications In kitchen

A common language and form of communication is necessary for appliances and

packaged food products. E.g Food barcode labels dispensing information about

package date through a scanner. The present day introduction of RFiD and

technologies like Wi-Fi has opened up new domains of interactivity.

Consider a future scenario. A user buys his daily set of groceries. Included is a can of

packaged milk .Each of these products are carry RFID labels. The packaged food

products are stored in the smart kitchen. The smart kitchen automatically remote

registers the new items stored. A central computing system is able to register details

like the location of storage – refrigerator or cupboard, date of purchase, quantity ideal

cooling conditions etc. Further the system keeps a track of consumption by the user and

display information as and when required. The refrigerator e.g. announces to the

personal computer the shortfall, orders to the computer of the supplier the supply.

A practical model of this concept has been now demonstrated by Microsoft10.

Microsoft’s smart RFID based microwave and kitchen counter that displays information

of food contents

Plate 5.4: Concept of a compact interactive kitchen 2 Source : www.cnnmoney.com

Microsoft recently introduced a prototype of "Home of the future" an example of smart

microwaves, fridge and smart counter. The microwave, for example, is fitted with an

EPC scanner. After you scan a can of soup that carries an RFID tag with the product

description, it automatically figures out the ideal temperature to prepare the food. The

smart refrigerator fitted with RFID technology. Someday it will be able to automatically

scan the contents and figure out what needs to be restocked or which items have hit

their expiration date


59

5.5 The future kitchen – future scope

In the 1956 film Design for Dreaming 11 --a promotional trailer produced by Frigidaire--a

housewife in the "kitchen of tomorrow" feeds a recipe card into a slot, triggering a series

of appliances that automatically bake a birthday cake complete with lit candles. Other

films of the era promised that future kitchens would include a transparent cylindrical

refrigerator! A robot butler! And an oven that cooks a roast in minutes " by electronics." !

Plate 5.5 - 5.6 : Scenes from the film Design for dreaming Source : www.wetcircuit.com Many of these fantasy’s still remain in our minds but are coming into existence in closer

insteps. The introduction of smart appliances like microwave , consumption of

packaged and preprocessed food as part of daily diet are all steps towards a future

which would integrate these advances.

It is said that future kitchens come and go.

The future kitchens have been always been perceived to be build on technological

sophistication. Technology today makes automation of mundane cooking tasks easier

like never before. However technology does has its limitations and would not become

popular if the gizmo laden future kitchen cannot establish an emotional attachment with

its users.

Plate 5.8 General Electric’s concept future kitchen launched in 2006. Source: http://www.geconsumerproducts.com/pressroom/ /kitchenoffuture

So what will be the shape of the future kitchen? What will it be like? Will it be like a

space craft with lots of controls? Look more like a museum with hidden features? Will a

special room called kitchens in today’s living room become extinct tomorrow? The future

kitchen going by present trends breaks the visual and functional rules of existing

kitchens. It is trying to shrink and blends with the existing living environment, just like

any other furniture or an appliance in home.


61

Today’s future kitchens are bold in usage of hard shiny material mostly stainless steel,

plastics and ceramics. Advanced new age materials are making inroads which facilitate

easy cleaning, odorless cooking. Efficient Systems like water saving improved washing,

OLED based lighting and waste management systems make the future kitchens

environmental friendly. Architecturally they use bold sculptural lines. Colors and

decoration area’s are as fantastical as the gadgetry. The future kitchen are loaded with

technology and gadgets and day is not far when they would be able to sense appetite

needs of the users and deliver foods at a voice command .

The concept of interactive kitchen may sound futuristic and exists only in skeletal form

today, This thesis attempts to show a direction that this could take in the form of

practical concepts and illustrations. These inferences were based on existing

developments in technology, changing user lifestyles, market trends etc. Development

of standard smart kitchen furniture is a complex task, requiring effective technology

integration onto mass manufacture able products. Kitchen s in the near future will see

integration of knowledge from areas like robotics, artificial intelligence, human computer

interaction and food technology. The present Indian furniture market is dominated by

the unorganized sector which boasts of a large pool of skilled workers but lacks

adaptability towards changing demands in furniture needs. It is of paramount

importance that Designers, Engineers, Architects, Entrepreneurs and Manufacturers

come together to set up productive teams. A team that understand Indian users as they

develop a sustainable smart kitchen concept that is marketable.

washing into four independent mobile modules. A module for storage and information

and communication display is added; together these four modules provide all basic

cooking functions in a compact area.

The concept inspiration came from four squares .These four squares were arranged for

maximum efficiency along the work triangle. Extrusion of squares into 4 cubes to take

form of individual furniture module wherein each cube performs the intended function..

6.11 Applying the “Divine Section”

A normal rectangle is not pleasing to the eye11 . Either it is too square-ish or it is too

slender. A divine section or golden rectangle is a rectangle which follows a fixed

geometric proportion and has proved to be carry aesthetic appeal when applied in

architecture and product design.

A golden rectangle have side lengths in the golden ratio, 1: , that is, approximately

1:1.618.

Since the basic forms in furniture to be designed were predefined to be cubes, the

cubes were attempted to follow the golden section as close to possible. It was also

necessary to keep in mind that the resulting geometry should also confine to the

ergonomic guidelines to suit functions it was being designed for.

Dividing the length of furniture by width, we get 864mm / 533 mm = 1.621

Golden rectangle value is 1.618

So the basic form designed is very close to a golden rectangle and hence final form might carry aesthetic appeal.

6.12 Scaled Prototype Testing Once the concept sketch was frozen scaled

models of concept was made. The models

were handmade by the author ( sunboard

material ). To give the models a feel of

reality scaled models of kitchen toy sets

were modified and fit into the existing

design .

During model making outmost care was

taken to create a model that approved most

of the ergonomic criteria’s of the design .

Once the models were made, the concept

was tested. All possible layouts and

configurations with available units were

tried that sufficed the kitchen work triangle

law. Most efficient and least efficient layouts

were noted. This stage also tested the most

optimum position for touch screen

information display.

Based on testing at this level the author

carried out iterations in the concept For e.g

the tall storage unit was eliminated in final

concept since it posed serious restrictions

on mobility and would have become too

bulky for transportation. In place of closed

tall unit a open utility rack was introduced of

smaller dimensions. Plate 6.3 Mock prototype Configurations

Conclusion

This thesis attempts to identify key user needs in Indian kitchen furniture for a migratory

population. This population segment is educated, on the move and requires kitchen

furniture that is modular, efficient and trendy. Henceforth concepts are proposed and a

physical prototype built that meets user requirements. The thesis takes a bold step

ahead in adding an interactive element to concepts which might become a standard in

the future.

This thesis however could not succeed on the front of physical realization of all

proposed smart features in kitchen. There were technical problems during development

and the present prototype is just a step forward. However, it does assimilate important

facts from users, trends in market and creates a usable product.

The contributions of this dissertation are stated as under

1. This thesis gives out a step by step approach which should be carried out in

developing commercial furniture starting from need identification to physical

product development and beyond. The author hopes that the process followed

could be useful to unorganized or small scale industries in gaining competency.

2. The thesis also documents relevant anthropometric data, important guidelines

necessary for planning any kitchen space or furniture. Reference to this thesis

work would acts as a quick guide to Indian ladies in creating efficient kitchens.

3. To the best of author’s knowledge, a concept like this for mobile kitchen does not

exist at present in the market. Future refinement of the idea on these lines and

development could create an indigenous product of high value.

This thesis is only a small step towards future development of an efficient smart kitchen. There is

scope of work over how physical embodiment of existing technology in communication,

information display, robotics etc takes place into the kitchen furniture in future.
