Approaches

12

CEN TC 224 WG 6

• Detailed design specification• Dseign process• Test methods• Principles• Usability • Adaptable user interfaces

Adam Balfour 2005

Deliverables TC 224 WG 6

13

CEN TC 224 WG 6

• EN 1332-1 User interface Dialog design principles

• EN 1332-2 Location & dimensions of a Tactile Identifier

• EN 1332-3 Keypads

• EN 1332-4 Coding of user requirements

• prEN 1332-5 Tactile marking - services

• Technical Specification ”Access”

Adam Balfour 2005

Basis - work on TC 224 WG 6

14

CEN TC 224 WG 6

• Software house - observation, video, task analysis,

assessment of user interface (1989)

• Nordic User Requirements 1994 - Observation/ interview,

task analysis

• EU TIDE Project 1040 SATURN - User Requirements -

interviews, observation, scenario analysis, task analysis

+ 300 in 3 countries

• EN 1332-1 User interface - Amendent 1 - testing N +300

• EN 1332-2 Tactile Identifier - 100 users, statistically sig.

• prEN 1332-5 Tactile marking - services

• Technical Specification ”Access” - EU funded Project

Adam Balfour 2005

Part One: User Interface Dialog design

15

CEN TC 224 WG 6

Approach: User Interface Principles - entering, navigating , exiting system. Annex with icons, symbols, pictograms

Status -to be revised/updated from 1995.

Issues• Take account of new handheld technologies/applications• What is generic, application specific, vendor solution• Take account of Universal Access

Adam Balfour 2005

Part Two: Tactile identifier

16

CEN TC 224 WG 6

Approach: Define locations and dimensions of notch.Basis for ETSI & ITU standard.

Status -not subject to revision - highly controversial.

Issues• Highly controversial -challenge to technolgy/ space on card

Adam Balfour 2005

Part Three: Keypads

17

CEN TC 224 WG 6

Approach: Define locations of 0-9 and function keys on pad.

Status subject to revision - controversial.

Issues• Controversial -challenge to different country standards/ application area standards/ suppliers• Real user issues not covered - but to be included in revision• Size of keypads & keys: handheld vs public terminals.

Adam Balfour 2005

Part Three: Layout variations

18

CEN TC 224 WG 6

Part Three: Keypads ECBS/TC1/ WG 11

19

CEN TC 224 WG 6

Adam Balfour 2005

Part Three: Keypads - issues

20

CEN TC 224 WG 6

• Size of keys• Distance between keys• Differentiation between keys• Differentiating different types of keys • Forces required to activate keys (2N- 20 N) • Feedback - key activation - visual, tactile, sound• Discriminability of key legends - visual, tactile• Comprehensibility of icons, symbols, pictograms on keys• (Mis)use of colour/ lighting• Keys on screen (touch screens)• Location of keys

Adam Balfour 2005

Part Three: Keypads - approaches

21

CEN TC 224 WG 6

Which approach?

• Define details in standard (e.g. Forces)• Develop a test method• Develop usability criteria• Develop a design process standard• Combination of above

Adam Balfour 2005

Part Four: Coding of users needs

22

CEN TC 224 WG 6

Approach: Adaptable user interfaces

• Code requirements on tag e.g. All information in English, Larger text, grey tone scale only, etc• Code need - not users characteristics• Could be stored on card, in PC, phone, terminal, host, etc

• Issues•? How to identify new requirements before new technologies mature• Testing - does it work

Adam Balfour 2005

Part Five: Tactile marking of services

23

CEN TC 224 WG 6

Approach: Define tactile markings for services. Confirms which card you have.

• Different services - different embossing

•Status: CEN Vote

Issues• No input from ISO - now want to get involved. • Controversial - technological, space,• How to update card with new services?• Multifunction cards

Adam Balfour 2005

Part ”Six”: TS ”Access to cardsystems”

24

CEN TC 224 WG 6

Approach: Define criteria for accessibility to card reading devices - physical, visual, acoustic.Based on EU funded project team.

• Status: CEN Vote

Issues• Highlly Controversial - legally binding - costly to implement• Only TS - not standard -therefore not enforceable• Different countries - /application areas - different codes• Will need regular updating, ++

Adam Balfour 2005

Future activities

25

CEN TC 224 WG 6

• Coding of user requirements on smart cards

• Electronic signatures – MMI

• Interactive TV, UMTS ?

• European Citizens Card

• Multi function card

• Revision of existing standards /reflect interactivity

• Self configurable smart cards

• (applications/services)

• Ubiquitous user interfaces
