Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Human Factors (HF). I n t rod uct ion The need for a single identifier to cover a rang

    33、e of communications services has long been acknowledged and many proposals, albeit less ambitious than the Universal Communications Identifier (UCI), have been defined and even field-trialled. No approach so far could be described as an unqualified success and, almost, without exception, that lack o

    34、f success has been due in some measure to usability issues. In the past these systems have either been too difficult to use or so intrusive and time consuming that users perceived insufficient benefit to encourage them to take up these services. People now tend to communicate more often and using a

    35、wider range of methods (e.g. mobile phones and several email accounts) and hence the need for services to manage personal communications has increased. The approach to speciSling the Universal Communications Identifier UCI has been different from any other. Firstly, it is a truly universal identifie

    36、r covering ALL communications services (including email) not just telecommunications services. Secondly, the UCI has been defined with continual reference to a precise set of user requirements (see annex B) relating to the management of personal communications. This approach is described in EG 201 9

    37、40 i. To achieve its full potential the UCI needs to operate within an architecture capable of supporting the concept of personal control of communication and this is described in EG 202 067 2. With the advent of new architectures and services, users can define precisely under what circumstances and

    38、 with whom they are prepared to communicate. One of the biggest selling points of the UCI system is the capability of increasing the users control over their communications, incoming and outgoing. With an increase in the capability to speciSl customized communications management comes an inevitable

    39、increase in complexity of the user interface to implement and oversee that capability. The purpose of the present document is to build on the work done in 11 and 2 and to define and analyse the user tasks inherent in implementing a UCI based communications architecture and to highlight usability iss

    40、ues. Future guidelines will then use the analysis included in the present document, taking the defined task elements, applying usability best practice and recommending areas for usability guidelines where appropriate. Adoption of these recommendations will mean that the chances of successful impleme

    41、ntation and uptake of UCI based communications will be maximized. ETSI 8 ETSI TR 103 077 VI .I .I (2002-1 1) 1 Scope The present document will expand on the issues relating to usability already identified in the following two documents, EG 201 940 i and EG 202 067 2, which identified the critical im

    42、portance of the usability issues associated with Universal Communications Identifier (UCI) systems. The present document identifies usability best practice relating to communication services and then considers the implications of applying such best practice to the user tasks necessary for implementa

    43、tion of UCI based services whilst still meeting the relevant User Requirements defined in EG 201 940 i (and summarized in annex B). The present document suggests which of these issues are suitable for expansion into guidelines. Other areas which require further investigation, before guidelines are p

    44、roduced, are highlighted in the relevant clause of the present document. Further illustration of some of the usability issues associated with UCI is raised in annex A. Annex A takes the 6 scenarios that are contained in EG 202 067 2 and uses them to highlight potential usability issues associated wi

    45、th UCI. Issues raised in annex A are discussed further in the body of this present document. It is intended that the present document together with the future guidelines, will provide information and guidance for: terminal and service designers (telecommunications and IT); service providers (telecom

    46、munication 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. 2 Re fe re nces For the purposes of this Technical Report, the following references apply: il 21 ETSI EG 201 940: “Human Factors (HF);
