Innovative Applications
• Celedu
Digital Libraries
• Bookshare
• Bibulio-net in Japan
• Access to a network of talking books
(12,395 titles as of March 2009)
• Proposed solution for India
Relay services
• Relay services are usually human operated
services for media and mode translation during
phone conversations.
• Provision of such services well integrated in the
phone system is an important backbone
capability for accessible phone services.
• Relay services are usually provided as
community supported services in some way,
because the operation of them require much
more human resources than regular person to
person calls.
Types of Relay services
• Video relay services, translating between sign language in video
and speech in a voice phone.
• Text relay services, translating between real-time text in the text part
of a phone and speech in a voice phone, usually for people with
speech impairments, hearing impairments, deafness or
deafblindness.
• Speech-to-Speech relay service, supporting speech calls for people
with speech impairments or cognitive disabilities.
• Captioned speech relay services (Captioned Telephony), adding
real-time text captions to a voice call, for people with hearing
impairments or deafness.
• In all these cases, the other media (voice, video, text) may be
handled as well in the call, ideally connected in two or three party
call mode between the parties in the call who have terminals that
can handle these media.
Prerequisites for the Integration
of Relay Services
• Calls to a number for a person with disabilities should be
able to invoke a relay service selected by the user if the
user so decides.
• Call from a person with disabilities to another number
should be able to invoke a relay service selected by the
user if the user so decides.
• Calls between two users who can and want to use the
same modes and media in the call should be possible
without invoking any relay service.
• Relay services should work with all commonly used
handsets and terminals.
• Users need to be able to use the same terminal for calls
directly in modes they handle, as is used for calls
through relay services and with emergency services.
Emergency and customer care
services
• Telecom regulatory authority needs to set standards for emergency
services to be implemented by operators and public services
• call emergency services
• use a common regional emergency number and
• have an efficient emergency call that rapidly results in a suitable
action.
• use the same conversational terminal for the emergency call that
they use for everyday calls
• communicate in the modes and media they use in everyday calls.
• get calls back from emergency services in the same media and
modes.
• get relay services included in the call if the user wants or needs to
have such services in the emergency call.
NTT DoCoMo Case Study
• Applying Three Tenets of Universal Design:
• User centered: Recognizing the range of
different capabilities and skills, past experiences,
wants and opinions within the population
• Population aware: Understanding the
quantitative population statistics is vital to inform
design decisions
• Business focused: Achieving profitability in the
commercial context and sustainability in the
public context
The Raku Raku Story
• NTT DoCoMo Market Situation in 2001
• Overall penetration of cell phones in Japan:
82.6%
• NTT DoCoMo market share: 51%
• Opportunity: rate of utilization decreases
significantly with age (90+% aged 20 to 50; less
than 30% above 70)
• Decision to tackle issue across organization,
products and services
• Adoption of Universal Design principles
• Cell phone handsets, stores & services
Example of “Raku Raku”
• A large screen with large characters
• Dedicated buttons to call certain pre-recorded
numbers automatically
• “Read aloud” menus and text
• Voice input text messages and email
• Access to a network of talking books (Bibulionet, 12,395 titles as of March 2009) with an
integrated DAISY player
• An optional bone conductor receiver to transmit
sound waves directly from bone to nerve
5 UD Principles for Cell Phone by
docomo
