Christoph Jung, Fraunhofer IGD / EU project GUIDE: "European Project GUIDE: User centered multi-modal interaction design for hybrid TV applications and platforms"
The European project GUIDE “Gentle user interfaces for elderly people”
(www.guide-project.eu) is developing a software framework which allows
developers to efficiently integrate accessibility features into their
applications. GUIDE puts a dedicated focus on the emerging Hybrid TV
platforms and services (Connected TVs, Set-Top Boxes, etc.), including
application platforms as HBBTV as well as proprietary middleware
solutions of TV manufacturers. These platforms have the potential to
become the main media terminals in the users’ homes, due to their
convenience and wide acceptance. Especially for users of the elderly
society applications such as home automation, audiovisual communication
or continuing education can help to simplify their daily life, stay
connected in their social network and enhance their understanding of the
Currently the GUIDE consortium is conducting user trials with elderly
people, which aim at gathering data for user modeling and to evaluate
acceptance of multi-modal interaction schemes for the users. This
presentation will provide an overview of the evaluation approach and
preliminary outcomes from the tests.

Audio Description (AD) is an additional audio track with narration for
all, but especially for blind and visually impaired people. This service
can be delivered using different techniques: over DVB-T with the help of
a second pair of audio channels (broadcast/broadcast) or with the help
of a shared distribution, broadcast and broadband via the air and the
web (hybrid solution), even a fully web based solution can be considered
(WebTV). Because the AD audio track can be delivered using technologies
that are not currently tested for this purpose it is regarded as an
emerging access service.
During the project we posed and tested five different scenarios. Several
tests were conducted in order to validate these. Tests focused on
evaluating usability, usefulness and quality of the audio description
services. In this presentation the scenarios are presented graphically
followed by results and conclusions of the evaluation tests. As each of
the different scenarios implies a differentiated service, the results
are presented individually for each of the five evaluated scenarios.

The Deaf perspective: Audio-Visual Media without Audio
Millions of people worldwide suffer from hearing problems, an invisible
and therefore an often neglected disability.
This disability prevents access to most audio-visual products. But an
increasing number of recommendations and laws require access for all.
But where starts real accessibility for all and what are the rationales
for such actions?
What are the tools to make audio-visual products understandable without
the audio part? What are the technological problems for transmitting
sign language interpretation and captioning? And what are the
technological requirements to ensure that accessible audio-visual
products are really arriving on the screen of the consumer?

TV is a central part of life for most people. This is no different for
disabled people. New digital and online forms of television can be a
good thing, but often bring barriers to disabled people.
Both programme content and TV receivers need to be made accessible so
that everyone can benefit fully from TV. Regulation has its role to
play, and the reference point for all regulation in this field should be
the UN Convention on the Rights of Persons with Disabilities.
EDF and EBU have been working with industry to remove barriers, but with
so far only partial success. We need joined up action from users, policy
makers (Commission ITU) Standards bodies, broadcasters, TV manufacturing
industry to ensure end-to-end accessibility.

The accessibility and usability project was started in IEC TC100 with a
survey which was designed and distributed to the IEC TC100 P-members to
obtain information about the related issues, public policies and
activities. As a result the project team produced the Technical Report
TR 62678 Audio, Video and Multimedia Systems and Equipment Activities
and Considerations related to Accessibility and Usability which attempts
to explain the possible relevance of accessibility and usability to the
IEC TC100 programme of work. The TR provides information on
accessibility and usability terms, activities, completed and ongoing
standards, technical reports, projects and specifies user needs that may
or may not apply to audio, video and multimedia systems and equipment.
Comments about demographics and public policies are included. A
checklist of accessibility and usability considerations is also
included. Industry experts may or may not apply this information when
they evaluate opportunities to integrate support for accessibility and
usability in their work.
