The
e
Europe and i2010 Initiatives


•
Launched by the European Commission in 2000: “
eEurope 2002
–

An Information Society For All”


•
Intended to accelerate positive change in the EU

•
Aims to:

•
secure equal access to digital systems and services for all citizens

•
promote computer literacy and

•
create a partnership environment based on trust and enterprise

•
Ultimate objective: bring everyone in Europe on
-
line

•
Building on this success, in June 2002 the initiative was extended
into
eEurope Action Plan 2005

•
i2010 was
launched in 2005, complemented in 2007

Introduction and background (1/2)


•
The capabilities offered by mobile solutions evolve,

•
from only being able to make a call and use voice
-
mail to

•
downloadable personalization achieved through

•
ring signals,

•
software programs such as games and

•
the introduction of multimedia information services

•
such as navigation, mapping and directions,

•
traffic information,

•
text messaging and e
-
mail access,

•
quasi
-
cordless functionality,

•
music, TV and video call services.

World Class Standards

17

Introduction and background (2/2)

•
Connectivity and interoperability between

•
telephony networks,

•
personal computing,

•
the Internet, and

•
ever
-
smarter mobile terminals and services

•
Offer enormous potential for improving life.


•
Concern about whether next
-
generation products, services and their content will
provide a good user experience and be fully accessible to all people, including:

•
generic users,

•
less literate users,

•
children,

•
aging and disabled users.

•
Ensuring access to mobile communication for all is a common goal

•
vendors, operators, service providers,

•
users associations,

•
Policy makers (

The “Usability Gap”


•

“Featurism”
-

product complexity increasing

•

Range of mobile technology users broadening
–

from
children to elderly and disabled

World Class Standards

19

Decreasing the “Usability Gap”

•
Possible ways to decrease complexity include:

•
understanding of user needs;

•
excellent user interfaces;

•
simplicity of configuration;

•
personalization capabilities and

•
ease of operation.


•
Also the “usability gap” can be helped by:

•
technological advances (e.g. better speech recognition);

•
a maturing ICT industry.

•
taking special needs of children and elderly users with physical and sensory
disabilities into account.

25


Rationale for generic UI elements

•
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).

World Class Standards

26

Rationale for generic UI elements

•
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 (under expansion)

•
ETSI ES 202 076 Generic spoken command vocabulary
(under expansion)

World Class Standards

27

Rationale for generic UI elements

•
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
