Beyond the Final Frontier: Usability at Reuters Greg Garrison Director of Usability Group Reuters 85 Fleet Street, London EC4P 4AJ, U.K. This paper presents the Reuters Usability Group and its Customer Centred Design process both of which pivot around their life-force the customer. We describe how to build this process into an evolutionary, self perpetuating and continuously evolving life cycle of ever more relevant and responsive products. Everything that we do revolves around the centre of gravity set by our customers, creating energy and synergy that launches our product into the future.

Three general models of driver gap acceptance behaviour are discussed. They are: a) a fixed critical gap, b) consistent individual drivers, and c) inconsistent individual drivers. The limitations and implications of the models and the restrictions imposed by the nature of the data are discussed. The model in which each driver has a constant critical gap, distributed over the population, is closely examined, and it is concluded that the distribution of critical gaps cannot be estimated from data available from field observations. It is suggested that use of the distribution of observed accepted lags (or gaps) together with conditional probabilities of acceptance should be used in comparison studies. Truncated normal and Weibull distributions have been successfully fitted to empirical data on accepted lags and gaps. For the covering abstract of the symposium see TRIS 452544. (Author/TRRL)

The paper is concerned with the support of conceptual design activities in collaborative virtual environments. It proposes a new understanding of conceptual design from a social perspective that explains the levels of support that are needed/required for this type of CVEs and presents the development of a particular CVE that supports conceptual design in the area of interior space design. It is envisaged that the proposed approach can be employed to provide insight to designers of CVEs for conceptual design about the ...

International legislation and current technology provide the tools for better vessel traffic surveillance. Land- based systems are able to collect and process the information transmitted by vessels through the 'Automatic Identification System'. These systems possess a valuable set of information that can be exploited in a variety of useful applications of public interest. The University of the Aegean implemented 'MarineTraffic'

Cognitive theories explaining how intelligent behaviour and action is produced have been the basis for designing and implementing intelligent artificial systems. Although it is widely accepted that the notion of autonomous intelligent action consists of at least the concepts of intentionality, representation, meaning and information (Collier, 1999), it seems that their interrelations as well as their functional activation outside or

The majority of the current knowledge based systems/expert systems (KBS/ES), decision support systems (DSS), and management information systems (MIS) have followed the traditional pattern of dealing only with crisply defined, non-fuzzy (" hard") problem ...

This paper proposes and discusses the development of a methodological framework for the analysis, development and creation of design support environments for adaptive systems. Design and development of adaptive systems is currently a strong research theme which results from the dynamically changing requirements and preferences of the participants in interactive systems and may refer to various types of customisation and

This paper aims to provide a generic framework that will enable designers to better understand sustainability through the evaluation and synthesis of different existing tools, methodologies and frameworks. The main positions analyzed can be identified in the ecomodernist approach to design for sustainability (technical fix) and more radical notions of change. Even though these two sets of positions are not opposites, due to the contradicting characteristics of sustainability we can consider them to be on the edges of a spectrum surrounding sustainability. This spectrum supports the emergence of sustainability as a synthesis of these contradicting ideas. In approaches to design for sustainability, common characteristics have been identified present in most of these approaches. There are six main principles identified are : Holistic, Social, Cyclic, Safe, Effective and Local. These principles attempt to cover as much cognitive ground as possible in the field of sustainability. The goal of this process is to aid designers in achieving a better understanding through a consistent evaluation and synthesis of different existing tools, methodologies and frameworks. Such evaluation will enable designers to to understand the “worldview” of each tool, methodology and framework, compare them and choose, or synthesize the optimum according to the task at hand and the Weltanschauung of the designer.

The action of digitally signing has several intrinsic weaknesses that introduce syntactic and semantic distance between a signer and a relying party. As a result, digitally signed documents cannot be trusted and thus be widely deployed in pervasive environments. We evaluate the syntactic robustness of digitally signed documents by exploiting one key quantitative measure (the structural informativeness) and by comparing

Deliverable D0401 presents and justifies the IRIS approach to the Design Support Environment (DSE) and provides a first view of its conceptual, functional and technical architectural elements. In order to justify this approach, there is a need to review a wide range of work related to 'Design for All' ('DfA'). This task is still work in progress for the project;

This book constitutes the refereed proceedings of the 5th Hellenic Conference on Artificial Intelligence, SETN 2008, held at Syros, Greece in October 2008. The 27 revised full papers together with 17 revised short papers were carefully reviewed and selected from 76 submissions. The papers address any area of artificial intelligence; particular fields of interest include: Adaptive Systems, AI and Creativity, AI rchitectures, Artificial Life, Autonomous Systems, Data Mining and Knowledge Discovery, Hybrid Intelligent Systems ...
