Designing a digital home for older people
Technology can have a big impact on the health and well-being of
older people. Very few
electronic products for use in the home, however, are designed for
ease of use by older people eg TVs, phones, mobile phones, radios. With the rapidly
aging population in
all developed countries it even makes economic sense for companies
to design specifically for this market. Chris Millington
of Doro UK, outlines the key factors that product designers should consider.

The silver pound
The simple fact is that people are living longer.
Seniors and those with impairments make up a greater proportion of
the population and this means that the market for products
specifically designed for impaired seniors is vast. Common
impairments to sight, hearing, mobility and memory affect everyday
life for 45% of everyone over 75 and these people will make
up 25% of the UK’s population within ten years. To design
for this market a number of considerations have to be understood so
that the real needs of the older consumer are catered to.
Age-related physical impairments enter many
facets of a person’s life and are to a greater or lesser extent
detrimental to their wellbeing. However, it is not just about
quality of life, the difference between good and bad design has
important health implications too. Weakening of the joints and bones
in later life means that good ergonomic design is vital to avoid
injury caused by using household equipment over the course of a day.
This paper will investigate how technology can be
designed to help the aged do what they used to do without fuss, and
immeasurably improve their lives in the process. Whether reading a
book, speaking to a relative or simply making it to the phone before
it stops ringing, it is the little things that can really make a
difference.
Background
In 2005 there were over 68 million EU citizens with identified
impairments; this figure is set to rise to over 84 million by 2010.
In response, the EU commission has decided on an action plan for
better conditions for senior citizens in the information society and
has allocated more than £700 million for research. Its intention is
“to prompt significant development investments and the use of
user-friendly ICT tools and services, which integrate senior
citizens’ needs and promote policies in other areas by solving
problems linked with ageing”.
Within Europe, senior consumers have a
collective wealth of over £2,150 billion, while pension, healthcare
and nursing home expenses are expected to go up to 4-8% of Europe’s
total GDP.
Key factors in design
As we get older we experience more and more
difficulty in doing the things we enjoy and are used to doing.
Research into the characteristics of the elderly
have revealed key drivers and servicing needs. To really cater to
the requirements of the seniors market these issues have to be
addressed.
One of the key design considerations for elderly consumers is
price, ie the product has to be affordable. In addition, research has found that elderly
consumers do not wish to draw attention to any impairment they may
have, so demand their products fit in with their daily lives and not
draw attention to themselves.
Finally, research reveals that the most important
thing on seniors’ minds is the maintenance of their social network
and staying in touch with their loved ones. Therefore any tool that
can help this communication process is of vital importance to the
elderly. Coming in a close second is reading newspapers and books
and watching television. For those with impaired vision these simple
joys can become increasingly fraught.
Very few mainstream consumer electronics companies
are designing products for this increasingly important market
sector. It would pay for UK designers to remember the power of the
“Silver Pound”.
Five steps to designing to the
silver surfer standard
1. Simplicity
Maintaining simplicity is vital in designing for the
elderly. While certainly not Luddites, seniors are not the most tech
savvy consumers and find excess functionality a chore and difficult
to get to grips with.
An example of simple design that helps avoid
unnecessary confusion is the world’s simplest mobile phone from
Doro, the Swedish consumer electronics manufacturer. The company has
created a GSM mobile with only seven large, clearly defined buttons,
a dialling/answer, disconnect and five memory buttons. The handset
can be used with any service provider and ensures that elderly
consumers always have a communications tool at hand to get in touch
with their five key contacts, whether it is in an emergency or to
just chat.
Even the simplest things can have a big impact on
the quality of life for many seniors. The excess functionality on many
remote controls is
confusing and unnecessary. A universal remote with a comfortable,
ergonomically designed grip, only the keys necessary for normal
operation, and that works
with more than one device, can reduce confusion for the elderly and
ensure they do not miss their favourite programmes.
2. Ergonomic design
Good ergonomic design is vital to ensure that
repetitive strain injury and damage to musculature and brittle bones
does not result from the elderly and infirm using a gadget.
Industrial designer Professor Maria Benktzon has worked at the
celebrated Swedish design firm, Ergonomidesign, for over 35 years.
She has used her experience of designing for markets as varied as
aeronautics and catering to ensure that products are lightweight and
well fitting.
Currently there is a trend among many technology
companies to place weights in their handsets in order to make them
feel more luxurious and expensive. However this means that the
elderly are discriminated against in order to cater to a consumer
fad. This excess weight can negatively impact their quality of life.
Much of Doro’s Care range, designed by
Ergonomidesign, is built from the ground up to be lightweight with
seniors in mind. The handsets are created to be easy to grab hold of
and replace, ensuring those with arthritis can stay in touch with
friends and family without discomfort and pain. Even the keypad is
easy to reach on the products; the user’s arm can be supported at
the table level, while the numbers are typed in.
3. “The three Bs”
The Royal National Institute for the Blind (RNIB)
has classified that the three Bs: bigger, brighter and bolder, are
key for those wishing to design products for the partially sighted
or severely sight impaired. A large legible keypad with high
contrast numbers is the minimum necessary when considering the needs
of the partially sighted. In addition, displays, such as on a phone,
should be large with high-contrast,
with the facility that the display can be reversed (black
figures on a white background and white figures on a black
background) also recommended.
By following the three Bs designers can ensure that
their products are tailored specifically for an increasingly
demanding market sector.
4. The little things
Even the smallest aspects of a product’s design can
have a great impact upon its usage in the hands of an elderly or
impaired person. For example, arthritis and loss of sensation
exacerbate dexterity problems. Often seniors cannot feel when they
are pressing the tiny buttons on many modern phones. With this in
mind, Ergonomidesign and Doro developed a range of phones with large
concave buttons; meaning fingers are less likely to slip off. In
addition it is not just about the size of the buttons on a phone,
but the gaps in between can be just as important, this ensures the
wrong button is not pressed by mistake.
Other considerations must revolve around the needs
of other people in the house, as often the elderly consumer will be
living with a younger carer. For example, what if the carer needs to
use a phone specifically designed for those hard of hearing members
of the house, their hearing could be damaged by the high decibel
levels. Therefore designers have to think about easy-to-use ringer
volume and receiver volume to suit everyone's individual needs.
5. Start from the ground up
Hearing aid compatibility has to be built into both
corded and DECT phones from the ground up as the radio frequency
emitted from the back of handsets interferes with most modern
hearing aids.
Doro found that a number of their elderly users
would have to take off their hearing aid in order to answer the
phone and once the conversation was over they would forget to put it
back on again. Phone conversation using a hearing aid is not easy.
The microphone is on top of the ear and not where the receiver is
and touching the hearing aid with the phone generates a lot of
noise. Obviously this was unacceptable and detrimental to their
lifestyle.
To solve this serious problem Doro created a headset
specifically for hearing aid users to connect directly into their
range of Care communication devices. Instead of a normal receiver, a
hook placed close to the hearing aid transfers the sound and
interference is nullified using magnetic coils.
A ringer indicator is also vital for many seniors
who cannot always hear the phone ringing. Bright lights that reflect
off household surfaces are yet another vital indicator for those
hard of hearing.
Conclusion
Successful design for the elderly and impaired is
about inclusion and simplicity. The elderly do not like complicated
products and superfluous functionality. Planning in advance to cater
to elderly users' diverse needs while still ensuring that the price
point is right is a delicate balance. Get it right, though, and life
for the elderly can be immeasurably improved.
