A Meta-service for Event Notification

The integration of event information from diverse event notification sources is, as with meta-searching over heterogeneous search engines, a challenging task. Due to the complexity of event filter languages, known solutions for heterogeneous searching cannot be applied for event notification

HDLalert - a healthcare DL alerting system: from user needs to implementation.

In the health domain, there are many circumstances where clinicians (i.e. doctors, nurses, allied health professionals) and patients wish to track changes in medical knowledge. However, existing ‘news’ or ‘alert’ services provide relatively limited means for selecting which information to receive. The result is that clinicians and patients often receive information that is inappropriate, irrelevant or simply too much. In this paper, we detail alert-relevant findings from several international user studies (e.g. UK, Germany and New Zealand) incorporating both clinical staff (across several hospitals) and patients’ perceptions. These findings demonstrate the importance of context, in terms of both the users task and immediate environment. We introduce a novel alerting architecture that can provide a finely tailored stream of alerts to the user, and provides further support to assist the interpretation of received material.

Requirements on dance-driven 3-D camera interaction: a collaboration between dance, graphic design and computer science

In this paper we describe our initial ideas towards research investigating dance-driven 3-D-camera interaction as a tool for creating holistic pieces of art for an enriched performance experience. In the first part, we focus on the technical analysis of requirements on a set o f input parameters for the dance input. In the second part we explore requirements stemming from the creative themes envisaged. In the discussion we synergize these requirements towards the requirements on a first prototype of the dance-driven 3-D-camera interaction.

Capturing context in collaborative profiles

In various application areas for alerting systems, the context and knowledge of several parties affect profile definition and filtering. For example, in healthcare nurses, doctors and patient influence the treatment process. Thus, profiles for alerting systems have to be generated by the explicit collaboration of several parties who may not know each other directly. We propose the new concept of collaborative profiles to capture these different conditions and contexts. These profiles exploit each single party’s expert-knowledge for defining the context under which (health-related) alerting is required. Challenges include the definition and refinement of profiles as well as conflict detection in context definitions.

Realistic books for small-screen devices

Realistic Books is a digital book reading software using the presentation of a physical book, while offering the advantages of digital books access. This paper describes our experience with transferring the Realistic Books concept onto small-screen devices, i.e., tablets. We compared and contrasted two interface approaches: adapted and tailor-made. We conducted a study of Realistic Books with the original software ported to small screens, in which a number of usability issues were identified. We also describe our tailor-made interface for Realistic Books, and the outcomes of our second study.

Dynamic previews for building digital libraries

This paper presents an investigation of alternative methods of digital library creation and configuration. Dynamic collection previews were utilized in order to assist collection administrators when creating and managing collections. Greenstone was used as a test-bed for investigating the potential benefits of this approach. A prototype was developed to explore the effects of dynamic previews when applied to one component of Greenstone collection configuration. A preliminary study indicated that users preferred dynamic previews to Greenstones traditional approach to collection configuration. Moreover, this paper identifies a number of potential avenues for improvement elsewhere within Greenstone and other DL management software.

Interactive definition of single-user profiles for alerting systems

This paper introduces Graphical Profile Definition Language (GPDL), a language for the definition of profiles for alerting systems, and an interactive system with which users can construct and edit GPDL-based profiles. In an alerting system profiles define potentially complex conditions about which users wish to be notified. Most current approaches to supporting profile definition, such as those that require the use of XML/XPath, are unsuitable for the general user population. Others support only a limited set of possible profiles to reduce the complexity of the interface. GPDL overcomes these limitations, supporting users to graphically express arbitrarily complex profiles involving Boolean expressions and temporal constraints. The GPDL editor provides a direct manipulation environment in which profiles can be constructed in a dynamic and flexible manner. The paper also presents the findings of a user evaluation of the GPDL language and editor. With minimal training users were able to interpret and specify profiles with high levels of accuracy and had positive subjective responses to the language and user interface. Some aspects that were not readily understood by all users, such as absolute and repetitive temporal constraints, are discussed along with suggested future work.
