  3. Background ■ The remarkable growth and advancement of information and communication technology (ICT), has not only caused a widening of the digital divide but has also created a serious problem for the elderly and persons with disabilities who find it difficult to use telecommunications services and devices. There is a need for guidelines for this group of people. ■ Telecommunications services, span country boundaries through networks, so it is essential to develop unified international standards instead of establishing guidelines for each individual country.

  4. Overall Scope of Accessibility JIS Basic standard Common standard Specific standard ■ISO/IEC Guide 71 (Released Nov. 2001), which clearly designates considerations for older persons and persons with disabilities in the development of products and services in all fields, and its JIS counterpart Z8071 Guidelines for standard developers to address the needs of older persons and persons with disabilities are at the highest tier. Lower tier specifications are as shown below. ISO/IEC Guide：2001 (JIS Z 8071:2003) Guidelines for Older Persons and Persons with Disabilities – Information and Communications Equipment, Software and Services – Part 1: Common Guidelines (JIS X8341-1) Enacted May 20, 2004 Part 4: Telecommu-nications Equipment Part 3: Web Content Part 2: Information Processing Equipment Part 5: Office Equipment (JIS X8341-4) Enacted October 20, 2005 (JIS X8341-5) Enacted January 20, 2006 (JIS X8341-3) Enacted June 20, 2004 (JIS X8341-2) Enacted May 20, 2004

  5. Accessibility in ISO ■ The Guide 71* in 2001 was developed to provide guidance to writers of relevant International Standards on how to take into account the needs of older persons and persons with disabilities. ■ This Guide applies to products, services and environments encountered in all aspects of daily life and intended for the consumer market and the workplace. *ISO/IEC Guide 71:2001

  6. ITU-Q26/16 ■ In ITU, Accessibility activities started over 10 years ago when work on text telephones started. ■ This was extended to F.703 - Total Conversation and V.18forreal-time text, video and voice communication in one mainstream telecom service useful for all. Type, sign, show, talk - all in the same call - total conversation. ■ In the last study period, TelecommunicationAccessibility Checklistfor standards writers (11/2006) and F.790 - Telecommunications accessibilityguidelinesfor older persons and persons with disabilities” (01/2007) were developed. ■ Coordination with other relevant ITU-T SGs : Study Group 16 has cooperated with other SGs to assure accessibility in new technologies, such as next-generation networks (NGN), Home Networks and IPTV. http://www.itu.int/ITU-T/studygroups/com16/accessibility

  7. Accessibility Standard in ITU SG16 (in case of F.790) At the first SG16 meeting in Nov. 2004, Japan proposed the development of Telecommunications Accessibility Guidelines. April, 2005: Q26 Interim meeting July, 2005: 2nd SG16 Meeting Nov., 2005: Q26 Interim meeting April, 2006 3rd SG16 Meeting Nov. 2006: 4th SG16 Meeting Agreement reached on Recommendation proposal for Telecommunication Accessibility January 13, 2007:Approval as Recommendation F.790 adopted after four weeks of Last Call http://www.itu.int/ITU-T/studygroups/com16/accessibility/index.html

  10. Process for Telecommunication Accessibility Standardization in ITU-T SG16 Q26 ■ In Telecommunications, services and terminals are inter-related necessitating collaboration with networks. Note that network functions cannot be easily changed after implementation. ■ In order to include Accessibility Requirements in networks, it is important to input them during the network development stage. The current checklist is very important. ■ In order to include Accessibility requirements in terminals clearly, an Accessibility check list for Manufacturers (Products guide) would be useful.

  11. Current Status Network The rights of Persons with Disabilities Human-centered design Telecommunications Accessibility Guidelines(F.790) Service Requirements Input for Standard writers Recommendations Accessibility Checklists (Standard Experts) ITU-T

  12. Proposed Implementation Network e.g., F.790 Annex/Appendix ITU-T Telecommunications Accessibility Guidelines(F.790) For Manufacturers Service providers For Standard writers Recommendations Accessibility Checklists Accessibility Checklist Products (Standard Experts) (Standard Experts) (Manufacturers Engineers) Related Qs． Promotion Governments Policy and regulatory framework

  13. Acknowledging Products Fulfilling Accessibility Criteria ■The Info-Communication Access Council releases the names and the evaluation checklist on its website for products which fulfill the accessibility criteria set out in the Guidelines. The accessibility logo designating products fulfilling accessibility criteria （example） （example） - “Read aloud” function allows user to choose commands from the menu or use e-mail or i-mode functions without relying on vision. - “One-touch dialing” allows the user to make a call by pushing a single button.

  25. Summary • Approach for ITU Accessibility is harmonized with the UN Accessibility Convention Article 9. • The Accessibility check list and guidelines are useful for promoting the Accessibility for the persons with disabilities. In order to improve its Telecommunication Accessibility documentation, ITU-T should proceed to develop and publish an Accessibility check list for Manufacturers productsguidelines. • Accessibility is a necessary part of Infrastructure, therefore governments should push network providers and devices manufacturers to support the Accessibility Guidelines. Governments should play a key role in promoting policies and regulations which foster accessibility.

  26. Future Studies • To foster awareness among providers to promote development and provision of accessible devices and services which comply to the Guidelines, etc. • Enlarge the range of users by including older persons and persons with disabilities. • Evaluation of accessibility compatibility for equipment and services

  29. Spectacular growth in information and communication technologies (ICT), in particular, the rapid proliferation of the internet Significance of Telecommunications Accessibility More frequent contact with telecommunications in the course of work and daily lives Increasingly important to assure telecommunications accessibility Make it possible for older persons and persons with disabilities to operate and use telecommunications equipment and services with ease.

  30. Steps Towards Assurance of Telecommunications Accessibility • June 1998 Ministry of Posts and Telecommunications ・ Ministry of Health and Welfare“Study group on the promotion of info-communication system for life support” • Proposed the establishment of a Council to formulate and promotion telecommunications accessibility guidelines • Oct. 1998 Principles of Accessibility of Telecommunications Equipment for Persons with Disabilities (Announcement by the Ministry of Posts and Telecommunications, now the Ministry of Internal Affairs and Communications) • Nov. 1998 Launch of Telecommunications Access Council • July 2000 Guidelines of Accessibility of Telecommunications Equipment for Persons with Disabilities. (First Edition) • July 2003Name changed from Telecommunications Access Council to Info-Communication Access Council • May 2004 Release of Telecommunications Accessibility Guidelines for Older Persons and Persons with Disabilities (Second Edition) by the Info-Communication Access Council • Oct. 2005Based on the above Guidelines (Second Edition), JIS※ X 8341-4 (for Telecommunications Equipment only) adopted • January 2007Based on the above Guidelines (Second Edition), ITU-T adopts Recommendation F. 790 ※ JIS : Japanese Industrial Standard

  31. Significance and Objective of International Standardization of the Guidelines • The spectacular growth of info-communications technologies (ICT), in particular the rapid proliferation of the internet, has made the disadvantages more serious for those who cannot use telecommunications equipment and services, especially older persons and persons with disabilities. • This makes it more urgent to put guidelines in place which assure accessibility in telecommunications. • Telecommunications equipment and services are linked not only to domestic networks, but are connected to the rest of the world. Therefore, guidelines should not be put in place separately by each country, but a globally uniform standard is essential.

  32. Outline of the Guidelines (F.790) ■Recommendation Title: Telecommunications accessibility guidelines for older persons and persons with disabilities ■Summary: This Recommendation is intended to provide general guidelines for standardizing, planning, developing, designing and distributing all forms of telecommunications equipment and software and associated telecommunications services to ensure their accessibility for people with the widest possible range of abilities.

  41. Actual Examples of Accessible Devices and Services Please relay your message to the operator using sign-language on a video-phone or text (via PC or e-mail). ■PLUSVoice Corp. The operator will make the call on your behalf! Making phone calls on behalf of a person with a disability. When a person who is hearing impaired would like to contact someone by telephone, he/she can notify the center via video-phone, facsimile, e-mail or other means and an operator will make the voice call on his/her behalf. Voicecommunications The operator will make the voice-based call to the intended destination while you are still on-line and communicate your message to the recipient. The operators are ready to assist you The operator will relay any messages the recipient wants to communicate to you in real-time. Sing-language and text

  42. Actual Examples of Accessible Devices and Services ■Unicom “Densuke-kun” – Facsimile transmissions sent to cell phone handsets Faxed documents are sent to cell phone handsets. Older persons or persons with hearing disabilities can send emergency messages from their home facsimiles to cell phone handsets of friends and family members who are out of their homes, without any understanding of Internet access. The message is created on an A4-size paper. The message is shrunk to fit the screen of a cell phone handset, so the use of a magic marker with big letters and thick strokes is suggested. Send the document to the designated facsimile number of “Denjo-kun.” That’s all the sender needs to do! Approximately 15 seconds after the facsimile transmission, the pre-registered cell phone handset receives the message. It may take longer depending on the data traffic being handled at the mobile carrier.

  43. Actual Examples of Accessible Devices and Services ■Sanyo Electric Co. Bone conduction telephones “TEL-KU2,” “TEL-KU3,” “TEL-SKU2” By placing the vibrating telephone receiver on or near the ear or somewhere else on the head, the voice of the caller is translated into vibrations to the bone, allowing clear reception of the caller’s voice. Comes with a “slow speak” function which slows down the speed of the caller’s speech without changing the pitch. It converts the caller’s speech to approximately 1.75 times the original speed, making it easier to understand and allowing a comfortable conversation to take place. How bone conduction is done Normally, sound is transmitted via the tympanic membrane. With bone conduction, sound is converted into vibrations which are transmitted directly to the skull and on to the inner ear, from which the signals are carried to the brain via the auditory nerves and interpreted as sound.

  44. Actual Examples of Accessible Devices and Services ■NTT East, NTT West Silver Phone “Anshin SIII” A simple emergency notification device in which pushing the button notifies a pre-registered number. Comes with hands-free speaker-phone and other functions. Silver Phone “Fureai S” Connecting the optional control switch or breath sensor switch makes dialing possible without the use of hands. In addition, all keys are indented from the surface of the phone shell, making it possible to dial without relying on visual ability.

  45. Future Considerations ■Foster awareness among providers to promote development and provision of accessible devices and services which comply to the Guidelines, etc. ■Enlarge the range of users by including older persons and persons with disabilities. ■Become compatible for aged society and make considerations for older persons who have age-related disabilities. ■Deliberate evaluation of accessibility compatibility for equipment and services Create a society where all people, including older persons and persons with disabilities, can take advantage of telecommunications equipment and services.
