Satchell, Christine, Shanks, Graeme, Howard, Steve and Murphy, John (2006): Beyond security: implications for the future of federated digital identity management systems. In: Kjeldskov, Jesper and Paay, Jane (eds.) Proceedings of OZCHI06, the CHISIG Annual Conference on Human-Computer Interaction 2006. pp. 313-316. Available online
Federated identity management is often viewed by corporations as a solution to support secure online commerce by synthesising complex and fragmented user information into a single entity. However previous research (Satchell et al 2006) has revealed a new set of end user needs for the design of identity management systems. This paper explores these needs from an identity management provider perspective, finds both alignment and divergence in needs and identifies a generational shift as a major cause of the differing needs. Whilst X and Y generations do not react strongly to concerns about digital identity theft or misappropriation of information, they seek to create and control their digital representations to be streamlined, portable across domains and revealing elements of their real life identity. There is still a considerable challenge for providers who must look beyond 'security' and 'authentication' to include 'user control', 'synthesis', 'portability' and 'personalisation' in the design of their systems.

Satchell, Christine, Shanks, Graeme, Howard, Steve and Murphy, John (2006): Knowing Me – Knowing You. End User Perceptions of Digital Identity Management Systems. In: Proceedings of ECIS 2006, Göteborg, Sweden. .
Federated identity management systems synthesise complex and fragmented user information into a single entity. Literature from the identity management system providers note this integration extends many benefits to the end user and the privileges provided by digital identity authentication schemes have been well documented from this perspective. Less explored however, are the perceptions of federation from the user’s perspective. This paper attempts to address this gap by reporting on an empirical user study that examines the relationship between identity and technology. It emerges that while current federated systems satisfy user needs by allowing the construction of multiple digital data sets, the fragments of which are moored to a central identifier, they fail to provide the user with control over the capability to act in the ‘hatch’, ‘match’ and ‘dispatch’ phases of the digital identity lifecycle. Ultimately, this reduces the user’s trust in providers and results in reluctance to disclose personal details.

Murphy, John, Kjeldskov, Jesper, Howard, Steve, Shanks, Graeme and Hartnell-Young, Elizabeth (2005): The converged appliance: "I love it... but I hate it". In: Proceedings of OZCHI05, the CHISIG Annual Conference on Human-Computer Interaction 2005. pp. 1-10. Available online
The last decade has seen convergence marketed as one response to the challenge of users having to juggle an increasingly wide array of digital services, technologies and media. Key to this view is the assumption that by converging computer devices, and digital media, the value of technology for end users can be maximised whilst the overheads involved in purchasing, maintaining and orchestrating a variety of different technology solutions can be minimised. In contrast however, some authors have argued that convergence creates weak-general solutions, and rather we should be aiming for strong-specific technology by means of the deliberate design of multiple diverged devices. This paper contributes to the ongoing discussion of convergence and divergence. We discuss three apparently irreconcilable perspectives on the relationship between functionality and usability, and show that they are in fact complementary views of convergence. To ground this discussion we draw on the results of a recent cultural probes study of a cohort of early adopters of converged devices.

Shanks, Graeme, Sargeant, Richard and Abeyatunge, Sonali (1994): A Meta-Argumentation Workbench. In: Proceedings of OZCHI94, the CHISIG Annual Conference on Human-Computer Interaction 1994. pp. 153-157.
A number of models have been proposed to support argumentation in design, for example the IBIS and QOC models. These models aim to structure the deliberations which occur during the design process and provide an explanation of the designed artefact. Tools to support these models have typically been designed to support one type of model only. This paper describes an argumentation meta-model which forms the basis of a meta-argumentation workbench. The meta-argumentation workbench supports the generation of specific argumentation support tools and allows for the rapid prototyping and subsequent evolution of argumentation models. A prototype implementation of the meta-argumentation workbench is discussed and suggestions for further work are offered.
