Goals and Agenda

Goals Inform you about CEN TC 224 WG 6/ understand ISO SWG

Ask for advice

• NWI - Which approach?

• What exists already?

• What work is ongoing - could be deployed in short term?

Invite collaboration

Self Service Society - User interface CEN TC 224 WG 6

Person - personReplaced by Man-Machine:Challenges to communication / user interface

Slide 5© 2006 Human Factors Solutions

Key societal services: self service CEN TC 224 WG 6

Consequences - cannot use system?

Voluntary vs complusory ?

Slide 11© 2006 Human Factors Solutions

Approaches - User requirements CEN TC 224 WG 6

What we have:

Detailed design specifications

Principles

Adaptable user interfaces

What we do not have:

Design Process

Test methods

Usability

Slide 12© 2006 Human Factors Solutions

Areas future work

Security at the Man-Machine Interface Validation and Verification in realtion to design

process Presentational techniques of HMI of card

operated devices Biometrics Icons, symbols, pictograms for Biometrics Multi-application cards / convergence Contactless cards Micro payments Smart media and tokens Route identification for transport applications

CEN TC 224 WG 6

Status/background - NWI

Public procurement - requirements for universal access - now - support legislation (development ongoing)

Need to specify what is required - wrt universal access

Problem: What is required - context sensitive

Need to verify appropriate involvement + documentation of end users in design process

Need to objectively validate solutions - universal access - transparent - holistic

Choice of approach - based on Norwegian Standards (NORSOK) experience from another industry (Oil + Gas)

Initiative by Standards Norway + Convenor WG 6

Slide 14© 2006 Human Factors Solutions

NWI - possible approaches

1. Design process

2. Design guidance

3. Evaluation methods

4. CIF Usability

5. Combination

Slide 15© 2006 Human Factors Solutions

Option 1: Design process

Content:

Rationale for adopting universal design process

Principles for universal design

Planning the universal design process

Universal access design process activities:

Understand and specify context of use Specify user and organisational requirements Produce design solutions Evaluate designs against requirements

Annex: Sample procedure for demonstrating conformance to this standard

Slide 16© 2006 Human Factors Solutions

Option 1: Design process

Advantages:

Emphasis on design process – getting the framework in place for appropriate design and evaluation

Design process tailored to self service systems

Separate document is easier to work with

Disadvantages:

General design process is already covered in depth in ISO 13407

Design guidance and evaluation methods for self service systems are either in separate standards or are not available

Slide 17© 2006 Human Factors Solutions

Option 2: Design guidance

Content:

Rationale and benefits of implementing accessibility

Characteristics of those with special requirements

Design guidance:

Software Hardware

Slide 18© 2006 Human Factors Solutions

Option 2: Design guidance

Advantages:

Design guidance is specific to self-service devices – both software and hardware

Separate document is easier to work with

Disadvantages:

Accessibility guidance is covered in ISO 9241 Parts 20 and 171 + ETSI TC HF documents

Software side of the design (for general interfaces) is covered in ISO 16071

Design process and evaluation methods for self service systems are either in separate standards or not available

Slide 19© 2006 Human Factors Solutions

Option 3: Evaluation methods

Content:

Planning for evaluation

Methods

Why

When

What

Involvement of end users

Annex: Example structure of usability evaluation report

Slide 20© 2006 Human Factors Solutions

Option 3: Evaluation methods

Advantages:

In-depth description of the methods available

Methods tailored to design of self service systems

Separate document is easier to work with

Disadvantages:

Methods are already covered in other standards (e.g. ISO 16982, ISO 13407)

Choice of methods/ performance requires expertise

Design process and design guidance for self service systems are either in separate standards or are not available

Evaluation needs to be seen in design process context

Slide 21© 2006 Human Factors Solutions

Option 4: CIF for usability test report

Common Industry Format (CIF) for usability test report, tailored to self service and universal access

Similar to ISO/IEC 25062, which is general

Standardises the information recorded and reported

Improves understanding between supplier and customer

Simplifies supplier’s task

Template provides standard structure for contents

Slide 22© 2006 Human Factors Solutions

Option 4: CIF for usability test report

Standard used by:

Supplier:

Usability professionals to create reports in format required by customers

Customer:

Usability professionals to evaluate accessibility of product Technical managers and decision makers

Slide 23© 2006 Human Factors Solutions

Advantages:

Tailored to self service and universal access

Disadvantages:

Goes against the principle of ISO/IEC 25062 - which is the industry standard

Option 4: CIF for usability test report

Slide 24© 2006 Human Factors Solutions

Option 5: Combined

Content:

Rationale for adopting universal design process

Principles for universal design

Planning the universal design process

Universal design process activities

Rationale and benefits of implementing accessibility

Characteristics of those with special requirements

Design guidance

Evaluation methods

Annex: Sample procedure for demonstrating conformance to this standard

Annex: Example structure of usability evaluation report

Slide 25© 2006 Human Factors Solutions

Option 5: Combined

Advantages:

A ‘one-stop’ standard – all information in one place

Methods tailored to design and evaluation of self service systems

Disadvantages:

Standard could be large and difficult to manage

Time to market for standard

Process and methods are already covered in other standards (e.g. ISO 16982, ISO 13407)
