    ABSTRACT: The development and deployment of information technology, particularly mobile tools, to support collaboration between different groups of health-care professionals has been viewed as a promising way to improve disease surveillance and patient care in remote regions. The effects of global climate change combined with rapid changes to land cover and use in Amazonia are believed to be contributing to the spread of vector-borne emerging and neglected diseases. This makes empowering and providing support for local health-care providers all the more important. We investigate the use of information technology in this context to support professionals whose activities range from diagnosing diseases and monitoring their spread to developing policies to deal with outbreaks. An analysis of stakeholders, their roles and requirements, is presented which encompasses results of fieldwork and of a process of design and prototyping complemented by questionnaires and targeted interviews. Findings are analysed with respect to the tasks of diagnosis, training of local health-care professionals, and gathering, sharing and visualisation of data for purposes of epidemiological research and disease surveillance. Methodological issues regarding the elicitation of cooperation and collaboration requirements are discussed and implications are drawn with respect to the use of technology in tackling emerging and neglected diseases.

    ABSTRACT: Most 3D modelling software have been developed for conventional 2D displays, and as such, lack support for true depth perception. This contributes to making polygonal 3D modelling tasks challenging, particularly when models are complex and consist of a large number of overlapping components (e.g. vertices, edges) and objects (i.e. parts). Research has shown that users of 3D modelling software often encounter a range of difficulties, which collectively can be defined as focus and context awareness problems. These include maintaining position and orientation awarenesses, as well as recognizing distance between individual components and objects in 3D spaces. In this paper, we present five visualization and interaction techniques we have developed for multi-layered displays, to better support focus and context awareness in 3D modelling tasks. The results of a user study we conducted shows that three of these five techniques improve users' 3D modelling task performance.

    ABSTRACT: Today’s building automation systems must be capable of dealing with a large number of simultaneously occurring events. Human operators monitor these events in order to maintain situational awareness, to detect physical intrusion or hardware problems, and other irregularities. We transferred the so-called temporal mosaic charts to building environments and compared their use with entropy-enriched Gantt charts and classical logfile analysis.

    ABSTRACT: Existing computer technologies poorly support the ideation phase common to graphic design practice. Finding and indexing visual material to assist the process of ideation often fall on the designer, leading to user experiences that are less than ideal. To inform development of computer systems to assist graphic designers in the ideation phase of the design process, we conducted interviews with 15 professional graphic designers about their design process and visual information needs. Based on the study, we propose a set of requirements for an ideation-support system for graphic design.

    ABSTRACT: This study investigates the readability (interpretability) of information presented on a geographical map onto which a semi-transparent multivariate selection layer has been overlaid. The investigation is based on an information visualization prototype developed for a mobile platform (tablet devices) which aimed at supporting epidemiologists and medical staff in field data collection and epidemiological interpretation tasks. Different factors are analysed under varying transparency (alpha blending) levels, including: map interpretation task (covering "seeing map" and "reading map" tasks), legend symbol and map area type. Our results complement other studies that focused on the readability characteristics of items displayed on semi-transparent foreground layers developed in the context of "toolglass" interfaces. The implications of these results to the usability of transparency variable selection layers in geographical map applications are also discussed.

    ABSTRACT: Purpose ‐ This article aims to describe how people manage to integrate their use of paper and electronic documents in modern office work environments. Design/methodology/approach ‐ An observational interview type study of 14 participants from 11 offices in eight organizations was conducted. Recorded data were analysed using a thematic analysis method. This involved reading and annotation of interview transcripts, categorizing, linking and connecting, corroborating, and producing an account of the study. Findings ‐ The findings of the study can be categorized into four groups: the roles paper and electronic documents serve in today's offices, the ways in which these documents are managed, the problems associated with their management, and the types of fragmentation that exist in terms of their management and how these are dealt with. Practical implications ‐ The study has identified the need for better integrated management of paper and electronic documents in present-day offices. The findings of the study have then been used to propose a set of guidelines for the development of integrated paper and electronic document management systems. Originality/value ‐ Although similar studies of offices have been conducted in the past, almost all of these studies are prior to the widespread use of mobile and network-based shared technologies in office environments. Furthermore, previous studies have generally failed to identify and propose guidelines for integration of paper and electronic document management systems.

    ABSTRACT: Electronic cataloguing systems are used by libraries to provide search mechanisms for finding books in their collections. These systems provide limited, if any, tools for browsing content electronically in a manner similar to browsing books on physical library shelves. Furthermore, library patrons often struggle to physically locate and retrieve books, even after they have found what they are looking for using library catalogue systems. A number of prototype technologies have been developed in recent years to assist library users with the task of locating books. These systems are, however, rather limited in their functionality, and generally do not provide tools for remote browsing of library shelves. In this paper we introduce Metis, a system designed to allow virtual viewing of collections, and to assist with physical retrieval of books using a range of desktop and mobile computing devices.

    ABSTRACT: As telehealth systems are increasingly being adopted by healthcare providers, a growing number of medical practitioners need to learn to use such systems. Despite this, however, most medical schools do not currently include telehealth-related content in their curriculum. In this paper we demonstrate, through examples from our own experience, how the Problem Based Learning method can be used to incorporate telehealth systems in medical science education. We also present a survey of medical students and faculty, conducted at a university in Brazil, to gain the participants' opinions on the nu-case mobile telehealth system. The results of the survey show that nu-case provides support for a range of tasks that a telehealth system needs to cater for in the context of our application area.

    ABSTRACT: In recent years a growing number of information visualization systems have been developed to assist users with monitoring their energy consumption, with the hope of reducing energy use through more effective user-awareness. Most of these visualizations can be categorized into either some form of a time-series or pie chart, each with their own limitations. These visualization systems also often ignore incorporating contextual (e.g. weather, environmental) information which could assist users with better interpretation of their energy use information. In this paper we introduce the time-pie visualization technique, which combines the concepts of timeseries and pie charts, and allows the addition of contextual information to energy consumption data.

    ABSTRACT: Massively multiplayer online role-playing games, such as World of Warcraft, have become very popular in recent years. These types of games often provide the player with a wide range of game abilities, weapons, tools, options, stats, etc. which grow in number as the player progresses through the game. This in turn makes the user interface of the game more complex and difficult to interact with. Games such as World of Warcraft attempt to combat this by providing mechanisms (e.g. add-ons) for interface customization by the player. However, it is unclear which aspects of the game interface players prefer to customize, or what effects those customizations have on their gameplay experience. In this paper we present a survey of World of Warcraft players to identify their opinions on game interface customization preferences. The results of this survey are likely to apply to other massively multiplayer online role-playing games.

    ABSTRACT: Teaching elementary programming is a difficult and often frustrating process. Many students fail to grasp the basic concepts and drop out of their programmes of study. Although visual languages with some form of game element have been explored as a solution to this problem, evidence on the success of these is at best mixed, without much empirical evaluation to support various claims that are made by their developers. In this paper we argue for and present a more limited programming game system for teaching basic programming constructs to beginner programmers at junior high school level. We also present an evaluation of this game which shows that students participating in this study enjoyed playing the game and succeeded in advancing through progressively more challenging stages of the game, which rely on understanding the underlying programming constructs.

    ABSTRACT: Surveillance and diagnosis of new and emerging communicable diseases in remote regions, such as the Amazon, is a challenging task. These regions can be difficult to reach, are sparsely populated, and have limited medical and ICT infrastructure. Medical practitioners and community health agents who work in such regions often have very basic qualifications, and therefore have limited knowledge of new and emerging diseases. The increasing capabilities of mobile devices, such as tablets and smart phones, have made them a useful platform for delivery of medical services in remote locations. In this paper we introduce a system that could potentially support diagnosis of vector-borne diseases such as Bartonellosis and Leishmaniasis in areas where specialist healthcare is scarce. In particular, we focus on the image analysis and classification component of this system, which aims to reduce the chance of misdiagnosing these less common diseases as malaria.

    ABSTRACT: While for many years home automation (HA) used to be a niche market for technically minded home owners, chances are that HA will be in widespread use in the near future. There are a number of reasons for this prediction, some of which are elaborated in this article. By means of selected scenarios from ongoing projects we will illustrate how recent developments are guiding the future of HA domain.

    ABSTRACT: Information visualisation methods can potentially be employed to assist the work of epidemiologists and other health care professionals in mapping the spread of communicable diseases in remote areas, where the task of disease surveillance encompasses temporal elements such as changes in climate, land use and population movements. This paper presents an investigation into the use of time-based visualisation techniques coupled with geographical maps and support for distributed mobile collection of patient data. This study has focused on the development of an information visualisation prototype designed for use by epidemiology researchers on mobile platforms (tablets and smart phones). The prototyping activity has involved the participation of prospective users working in the Amazon region. Initial results are presented and discussed.

    ABSTRACT: It is estimated that global climate change and regional land use and cover changes in the Amazon region will contribute to the spread of vector-borne diseases such as bartonellosis and leishmaniasis. The large geographical distances and the sparsity of human settlements in the region pose challenges to the collaboration among health professionals whose goals range from diagnosing diseases to monitoring their spread. This paper presents work in progress on a system to support the tasks of local healthcare professionals and enabling collection, compilation, sharing and visualisation of data for purposes of epidemiological research and disease surveillance in remote regions.

    ABSTRACT: A mosaic chart has been proposed for representation of events on a timeline. While early studies demonstrated the effectiveness of mosaics in supporting visualization of multimedia records on a meeting browser, the usability of mosaics as a static timeline visualization has not been studied in more general settings. This paper investigates the use of the mosaic charts for visualization of project schedules. A user study was conducted to compare a building project schedule encoded alternatively as a mosaic or as a Gantt chart. Although the study focused on static graphs, for which the Gantt technique is usually very effective, results showed that the users were as fast and accurate at answering the questions using the mosaic representation as they were using Gantt charts. The analysis and experiment indicated algorithmic, space-filling and interpretation limitations of the mosaic technique. We suggest possible design improvements to overcome some of these limitations.

    ABSTRACT: Although there has been a surge in computer games research in recent years, studies of gamers' experience of different game genres are very few. Furthermore, even these few studies of gamers' experience are almost all based on Western/European players. In this paper we present a survey of Japanese gamers' ratings of the importance of a range of elements that contribute to their experience of playing games from different genres. The results of this survey indicate that the ratings of these elements are different across various genres; thus providing designers of each genre with a range of elements that they need to take into account when designing those specific types of games. The results also show that there are small, but significant, differences between males and females in their ratings of some game elements.
