Decreasing the “Usability Gap”• Possible ways to decrease complexity include:

• understanding of user needs,• excellent user interfaces,• innovation,• simplicity of setup and configuration,• personalization capabilities,• ease of operation.

• Also the “usability gap” can be helped by:• technological advances, e.g. natural interaction/direct manipulation

• speech recognition, touch screens • ICT maturity.

World Class Standards

Rationale for generic UI elements (1/3)• Manufacturers differentiate their products through industrial and

screen design, feature sets and UIs• Generic UI elements are accepted

• in safety-relevant products (e.g. cars), • for products to be used by many people (products in public or work

environments), and• In UIs following de-facto standards (GUIs in PC software or musical

instruments).

UMTS Forum GA; London, UK, 13th November 2008 14

World Class Standards

Rationale for generic UI elements (2/3)

• Generic UI elements result from• de-facto standards (e.g. GUIs), and from• official standardisation (e.g. keypad arrangement on

public phones).• Generic UI elements potentially benefit all,

• end users,• manufacturers, and• service providers.

• Can facilitate the uptake of new and emerging technologies and user interfaces, e.g.:• ETSI ES 202 130 Character repertoires, ordering rules

and keypad assignment, or• ETSI ES 202 076 Generic spoken command vocabulary

UMTS Forum GA; London, UK, 13th November 2008 15

World Class Standards

Rationale for generic UI elements (3/3)• Basic considerations of what makes a UI area a candidate for

generic UI elements:• No barrier to innovation• No obstacle to good product-specific user interfaces• Only the semantic of a generic user-interface element should be

specified, not the actual design and implementation• End-user aspects, such as learnability, familiarity, trust, configuration

and access• Commercial aspects (quicker uptake of new technologies, larger user

base)• Legal requirements and possible regulation

Guidelines for generic UI elements? For mobile???

• 12-key keypad character repertoire, mapping and sorting (ES 202 130):• Inconsistent, expensive, time-consuming• Irrelevant as a mean for competition, • Confusing to the user• Industry initiative lead to ETSI Standard for 28 languages, expanded to 101

• Spoken command vocabulary (ES 202 076)• A considerable effort made together

• better than anyone would have done it alone• ETSI Standard for 5 languages, now expanded to 30

• Accessibility design guidelines• Multimodal design guidelines, et cetera• Enabling and improving the use of mobile e-Services (EG 202 416 and

EG 202 417)• Generic UI design guidelines

• 2G and GPRS• 3G and HSPA (under developement)

Scope of the 3G-centric work• Expand the scope of EG 202 132 (August 2004) to 3G-specific issues

• Address specific 3G key issues from the end user's perspective• providing guidance for generic UI elements

• Simplify end-user access to ICT through 3G/UMTS devices• without restricting market players’ ability to develop their offering

• Consider user requirements and integrate available results of standardisation work• providing implementation-oriented guidance

• Do not limit options to trademark UIs or profile the user experience • of brand-specific UI implementations as a competitive edge

• Adopt a Design-for-All approach• Where reasonable and possible
