ETSI’s approach to ensuring design-for-all requirements

2. Why has ETSI updated its procedures?
In 2010 the EC published Mandate M/473: “Standardisation mandate to CEN, CENELEC and ETSI to include “Design for All” in relevant standardisation initiatives” that asked the ESOs to:
ensure that “Design for All” is considered adequately in the process of creating new standards.
In November 2010 ETSI accepted the Mandate.
As a result, ETSI agreed to design a procedure for ensuring that Design-for-All requirements be considered when starting a new standards activity.

3. What is “Design for All?
Design for All is the design of products to be accessible and usable by all people, to the greatest extent possible, without the need for specialized adaptation.
The effect of technology (and technical standards) on individuals is related to the capabilities of those individuals.

4. Design for All and the Capabilities of Users
Many users have one or several of the following disabilities:
Blind users and users with impaired vision;
Deaf users and users with impaired hearing;
Users with motor impairments (e.g. due to Parkinson disease, wheelchair users);
Users with cognitive impairments (e.g. dyslexia);
Users with memory limitations (e.g. due to Alzheimer’s disease).
Elderly users, too, may also have any combination of these.

5. The Need for Design for All
What is the motivation to apply Design for All?
The business case i.e. the realisation that money can be made by addressing the whole target population
Legal and regulatory requirements e.g. the German BGG (equality law for disabled people) e.g. EU mandates on public procurement
Social policy e.g. most EU countries have signed up to the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD)
Standardisation requirements

7. The ETSI Design-for-All Assessment Process
The assessment process as described in EG is as follows:
The potential relevance of Design for All (DfA) issues in the context of any ETSI deliverable to be developed or updated can be assessed by means of a DfA checklist.
Based on the specific checklist results, a set of relevant user needs can be identified and an indication given on how these user needs may need to be addressed in the deliverable.
The EG gives guidance on user interaction aspects relating to specific user needs, allowing further analysis of options to address those user needs in the deliverable

8. The DfA Checklist
The DfA checklist used in the DfA assessment deals with different options for how users may interact with ICT and services. It contains the following topics:
Control of devices through a user interface
Does the ETSI deliverable relate to or impact upon a device with a physical or logical user interface? E.g. buttons, voice commands, touch screens
Control of services
Does the ETSI deliverable relate to or impact upon a service with a physical or logical user interface? E.g. web forms
Media presentation to the user
E.g. voice announcements or visual display of information
E.g. video streaming

9. The DfA Checklist Media entry by the user (media capture)
E.g. uploading of photographs
Does not necessarily imply an active interaction e.g. monitoring the movements of people with cameras to identify atypical behaviour patterns
Media processing including transport, coding, transposition, etc.
NOTE: This category excludes lossless media transport where the media stream is not processed nor delayed by more than 100 ms
E.g. a low bit rate coding algorithm could reduce the video quality to the extent that it is unsuitable for sign language usage
User and device profile management and use.
E.g. a blind user could choose an audio rather than a visual user interface

10. The ETSI DfA Assessment Procedure (I)
1. When defining a New Work Item (NWI) you will be required to identify which (if any) of the DfA topics are applicable to your work item.
Note that it is the responsibility of the Technical Committee to decide that there is NO DfA-relevance in a NWI.

12. The ETSI DfA Assessment Procedure (III)
2. A basic explanation of each of the assessment topics will be provided, and further information can be accessed.

14. Summary In this presentation, we have shown:
How to decide if a specific new work item has DfA requirements;
How to identify specific DfA requirements for a standards document;
How to solve/fullfill specific DfA requirements in standards
How to use the DfA toolkit to assess all relevant DfA issues for a work item.
