Ms. Andrea Saks 
Independent Accessibility Consultant
Andrea Saks has been involved in deaf telecommunications since the mid 1960s and is the daughter of one of the deaf founders of the US TDD/TTY system. The United States was the first country to have deaf telecommunications. The deaf community was in fact the first group to embrace text communications for personal communication over the telephone network long before the Internet.

Because her mother went to a deaf school in Great Britain and at the request of her mother’s school friends, Ms. Saks was sent to set up the first deaf telephone system in the UK with the Breakthrough Trust in January 1973. She also organized the first Deaf Transatlantic call in 1975 involving the US Embassy, Lord Ashley (formerly Mr. Jack Ashley MP), and Ambassador Elliot Richardson from London to the Department of Health Education and Welfare in Washington DC, demonstrating the need for telephone compatibility for deaf people. When other countries including the UK began developing and using devices that were incompatible with the US system, Ms. Saks began her vocation of advising as many organizations, government bodies and businesses as possible on issues related to deaf telecommunications, worldwide telecommunication compatibility and civil rights issues for the disabled.

Since 1991 starting with CCITT SG17, Ms Saks has been a delegate on US delegations to various ITU-T study groups; advising on accessibility. As the SG groups and ITU-T changed and evolved, so did the work of Ms. Saks change; to include many more accessibility issues and aspects other than those that just affect the deaf community with regard to equal access to ICT.

Ms. Saks has advised the Federal Communications Commission and US State Department, and other regulatory bodies worldwide over the years. She also advised many telecommunications companies, manufactures of devices, network builders, emergencies, relay services and worked with, numerous deaf organizations throughout the world. . Her involvement promoting equal access in telecommunications has spanned over 40 years.

Ms. Saks is privately funded and has no commercial interest in her activities. Both her parents were deaf and she was the “deaf telephone” for her family from the age of two years until the TDD/TTY liberated her. Her strong interest is not only inspired by those who need to have access but for those who have in the past given and still give access to telecommunications without recompense or recognition. They are the children, family members and friends of those who need the access that industry still does not adequately provide.

Dr. Yoichi Kato 
VP and General Manager, Web Conference Systems, NTT-IT Corp.
Currently Yoichi Kato leads the Web Conference business MeetingPlaza of NTT-IT Corp., a subsidiary in the NTT group. MeetingPlaza is one of the most successful Web Conference technologies in Japan providing systems and services to more than 1,200 companies. Noticing the lack of flexibility in H.26x for multi-user communications (such as sessions with more than 20 locations), he designed a new video communication system for MeetingPlaza.

Yoichi Kato has been working in research and development of video conferencing systems for more than 22 years since he joined NTT Laboratories. In late 1980s, he actively contributed to the Specialist Group in SG15/ITU-T for making H.261, the most epoch-making video compression standard including commonly used elements in H.26x and MPEGx (such as DCT/MC/VLC, etc).
