USE CASES RELATED TO AMBIENT ASSISTED LIVING (AAL) IN THE
FIELD OF AUDIO, VIDEO AND MULTIMEDIA SYSTEMS AND EQUIPMENT
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a technical report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC TR 62907, which is a technical report, has been prepared by technical area 16: Active

assisted living (AAL), accessibility and user interfaces, of IEC technical committee 100: Audio,

video and multimedia systems and equipment.
The text of this technical report is based on the following documents:

INTRODUCTION

This Technical Report (TR) captures the results of a use case input process that began with

the call for contributions of AAL use cases on 2012-06-06. The current document reflects

contributions and discussions by IEC TC 100 national mirror committees, user organizations

and the ITU-T Focus Group on Audio Visual Media Accessibility. This Technical Report also

contains material gathered from reports, AAL research projects and group output from the

IEC TC 100 AAL stage 0 project team meetings in October 2012 (Berlin), June 2013 (London)

and September 2013 (Shenzhen). In total, seventeen use cases were submitted.

To start the project, a survey was designed and distributed to the IEC TC 100 P-members to

collect Ambient Assisted Living (AAL) use cases. The use case submissions consisted of the

title of the use case, a description and the origin of the use case. Also incorporated is the

relevance of the use case within the scope of IEC TC 100. These are mainly activity based

AAL use cases providing a user experience perspective from those who want to operate AV

and multimedia equipment or access AAL services. The use case template helped to group

and categorize the use cases according to the identified user requirements and experience of

usability barriers faced by users. Understanding the usability barriers made it easier to

identify categories and highlight use case commonalities. Where multiple use cases fall in the

same category and had overlapping items, they were consolidated into one extended use

case. All selected use cases have real-world validity. Gaps were filled by adding extra use

cases and future developments were also considered. Usability barriers and functional

requirements were extracted from the use cases and recommendations given for future

standardization items related to AAL.

There is a natural mapping from the user experience based use cases to the clustered

technical use cases, where specific technical and functional requirements are expressed.

The following national committees, liaison organizations and EU research projects contributed

use cases on Ambient Assisted Living:
a) IEC TC 100 P-members China, Germany, Japan, UK and U.S.;
b) the European Blind Union;
c) the ITU-T Focus Group Audio Visual Media Accessibility;
d) and the EU Research Projects GUIDE, Persona, universAAL and AALIANCE.

Technological advances have enormous potential to make the society more inclusive by

providing AAL solutions. The key issues relevant for IEC TC 100 which need to be addressed

include barriers to accessibility and usability, and interoperability and personalization to

ensure wide adoption.

This TR extracts and applies the user needs and accessibility principles published in

ISO/IEC Guide 71.
The target audience for the TR includes:
• AAL service users who can understand how their AAL needs and their usability
requirements are considered by an AAL service provider.

• AAL service providers who can learn about users AAL needs, and accessibility and

usability issues, and can also learn how to operate AAL systems.

• AAL application developers who can develop AAL applications according to the needs of

the AAL service users.

• CE and ICT device manufacturers who want to know what are the AAL needs of the users

and what barriers elderly people and people with disabilities face which are related to the

accessibility of interfaces and content.

Administrations and government authorities that have to act as AAL service users and

AAL regulators.

USE CASES RELATED TO AMBIENT ASSISTED LIVING (AAL) IN THE
FIELD OF AUDIO, VIDEO AND MULTIMEDIA SYSTEMS AND EQUIPMENT
1 Scope

This Technical Report comprises seventeen use cases for Ambient Assisted Living submitted

to IEC between June 2012 and September 2013.

The initial objective of this Technical Report is the identification of AAL scenarios and use

cases based on real-world applications and requirements. Use cases are a well-known tool for

expressing requirements at a high level with real-life relevance. The use cases provide a

practical context for considerations on interoperability and standards based on user

experience. They make it clear where existing standards can be further used and highlight

where standardisation work is needed.

The use cases are based on the identified requirements of elderly people and people with

disabilities. The use case scenarios demonstrate both the usability barriers and functional

requirements. In addition, the accessibility principles developed in ISO/IEC Guide 71 were

applied.

A further objective of this report is to highlight potential areas for standardisation in the AAL

environment to ensure ease of operation and interoperability with a focus on specific aspects

relating to audio, video and multimedia equipment.
