The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members,

30、and can be found in ETSI SR 000 314: “Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp).

31、 Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the presen

32、t document. Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Human Factors (HF). Introduction The proposed Universal Communications Identifier or UCI would be associated with all the users electronic communication services, including email. It is, at the same time, both me

33、aningful and unique and has been defined with continual reference to a precise set of user requirements relating to the management of personal communications. This approach is described in EG 201 940 1. To achieve its full potential the UCI needs to operate within an architecture capable of supporti

34、ng the concept of personal control of communication and this is described in EG 202 067 2. TR 103 077 3 has defined user tasks which will be encountered within a UCI environment and highlighted areas suitable for guidelines. There have been many attempts made in the past to provide a single identifi

35、er covering a range of communications services. None could so far be described as an unqualified success and, almost, without exception, that lack of success has been due in some measure to usability issues. Use of unified identifiers in the past has either been too difficult or so intrusive and tim

36、e consuming that users perceived insufficient benefit to encourage them to take up these services. New architectures and services will greatly enhance the ability of users to control their communications so that they can determine who can communicate with them and under what conditions. With an incr

37、ease in the capability to specify customized communications management (incoming and outgoing) comes an inevitable increase in complexity of the user interface to implement and oversee that capability. Usability is critical to the introduction of any advanced, sophisticated communications system suc

38、h as a UCI system. Unless usability is considered at all stages of development and implementation there is a real danger that users will perceive no net benefit. If such is the case then there is a real danger of failure. The present document builds on the work done in EG 201 940 1, EG 202 067 2 and

39、 TR 103 077 3 to produce usability guidelines. It has been based on a study of the user tasks described in TR 103 077 3, and the application of usability best practice. Adoption of these guidelines will mean that the chances of successful implementation and uptake of UCI based communications will be

40、 maximized. ETSI ETSI EG 202 249 V1.1.1 (2003-11) 8 1 Scope The present document provides usability guidelines relating to the development and implementation of UCI systems. EG 201 940 1 and EG 202 067 2 identified the critical importance of the usability issues associated with Universal Communicati

41、ons Identifier (UCI) systems. TR 103 077 3 has identified usability best practice relating to advanced communication services. It has discussed the implications of applying such best practice to the user tasks necessary for implementation of UCI based services whilst still meeting the relevant User

42、Requirements defined in EG 201 940 1. TR 103 077 3 also defined areas relating to usability which would be suitable for the production of guidelines. The guidelines are numbered consecutively throughout each clause in order to relate them to the context in which they apply. The present document also

43、 highlights areas in which it is not currently possible to define guidelines. Such instances will be because: there is insufficient research or experience relating to a particular usability issue; certain technical aspects of UCI system are insufficiently evolved or defined; there is a need for focu

44、ssed consultation with specialized groups of users such as elderly people, people with disabilities, young children and people from non-European cultures; simple guidelines may not be able to adequately address the usability issues associated with a complex functionality. Where guidelines have not b

45、een provided, it has sometimes been possible to highlight usability issues that should focus designers attention on specific areas that are critical to system usability. In dealing with the usability issues, it would be expected that designers should make use of usability design techniques such as:

46、focus groups for formalized user requirements capture; task analysis; user trials. Use of these techniques is advisable even where the guidelines in the present document are being used. Ideally, the present document, which defines usability guidelines, should be read in conjunction with TR 103 077 3

47、 which describes the background to all Guidelines. To avoid the need for constant cross-referencing between the two documents, much relevant text from TR 103 077 3 has been duplicated in the present document. The present document will provide information and guidance for: terminal and service design

48、ers (telecommunications and IT); service providers (telecommunication and IT); designers of external tools (e.g. calendar, address book) that may be used in a UCI context; user groups; other Technical Committees within ETSI.
