Slide 9© 2006 Human Factors Solutions Scope Scope TC 224 Identification Card Systems ”cross border, inter-sector interoperability - smart cards and card reading devices” Scope WG 6 ”Human System Interface” Standardise ” Man-Machine Interface” to make it accessible BY EVERYONE CEN TC 224 WG 6

Slide 10© 2006 Human Factors Solutions Deliverables TC 224 WG 6 CEN TC 224 WG 6  EN User interface Dialog design principles  EN Location & dimensions of a Tactile Identifier  EN Keypads  EN Coding of user requirements  EN Tactile marking - services  Technical Specification “Access”  Technical Specification “eURI”

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

Slide 13© 2006 Human Factors Solutions 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  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 ETSI TC HF documents  Software side of the design (for general interfaces) is covered in ISO  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 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)

Slide 26© 2006 Human Factors Solutions Your views?  Which approach?  What exists already?  What work is ongoing - could be deployed in short term?  Establishment of liaisons/ input/ collaboration
