Abstract:

Aims: A 10-month project funded by the NewMind network sought to develop the specification of a visualisation toolbox that could be applied on digital platforms (web- or app-based) to support adults with lived experience of mental health difficulties to present and track their personal wellbeing in a multi-media format. Methods: A participant co-design methodology, Double Diamond from the Design Council (Great Britain), was used consisting of four phases: Discover – a set of literature and app searches of wellbeing and health visualisation material; Define – an initial workshop with participants with lived experience of mental health problems to discuss wellbeing and visualisation techniques and to share personal visualisations; Develop – a second workshop to add detail to personal visualisations, for example, forms of media to be employed, degree of control over sharing; and Deliver – to disseminate the learning from the exercise. Results: Two design workshops were held in December 2017 and April 2018 with 13 and 12 experts-by-experience involved, respectively, including two peer researchers (co-authors) and two individual-carer dyads in each workshop, with over 50% of those being present in both workshops. A total of 20 detailed visualisations were produced, the majority focusing on highly personal and detailed presentations of wellbeing. Discussion: While participants concurred on a range of typical dimensions of wellbeing, the individual visualisations generated were in contrast to the techniques currently employed by existing digital wellbeing apps and there was a great diversity in preference for different visualisation types. Participants considered personal visualisations to be useful as self-administered interventions or as a step towards seeking help, as well as being tools for self-appraisal. Conclusion: The results suggest that an authoring approach using existing apps may provide the high degree of flexibility required. Training on such tools, delivered via a module on a recovery college course, could be offered.

Abstract:

Many algorithms for graph layout have been devised over the last 30 years spanning both the graph drawing and information visualisation communities. This article first reviews the advances made in the field of graph drawing that have then often been applied by the information visualisation community. There then follows a discussion of a range of techniques developed specifically for graph visualisations. Graph drawing algorithms are categorised into the following approaches: force-directed layouts, the use of dimension reduction in graph layout and computational improvements including multi-level techniques. Methods developed specifically for graph visualisation often make use of node-attributes and are categorised based on whether the attributes are used to introduce constraints to the layout, provide a clustered view or define an explicit representation in two-dimensional space. The similarities and distinctions between these techniques are examined and the aim is to provide a detailed assessment of currently available graph layout techniques, specifically how they can be used by visualisation practitioners, and to motivate further research in the area.

Abstract:

This study explores the role that information visualisation played in the popularisation of the technical-biomedical aspects of the last Ebola virus epidemic, the most devastating to date. Applying content analysis methods, the total population of information visualisations ( N = 209) was coded and analysed to identify topics, and to define features and identify patterns in the images. The corpus was based on the record of articles with graphics appearing in five Spanish reference newspapers from 22 March 2014 to 13 January 2016, the start and suppression of the epidemic, respectively. The results suggest that information visualisation was a key factor in the popularisation of the epidemic’s technical-biomedical aspects, as well as contributing actively to construct, in the words of Myers, a narrative of nature.

Abstract:

Abstract The paper provides a detailed overview on forest models from various perspectives. The presented classification scheme of forest models uses concept, object, space and time as variables to place models in specific categories and thus provides an integrated approach for model categorisation. A short description of individual categories with the examples of models helps to understand their nature. In total 34 forest models were classified according to the created scheme. Forest visualisation has also an important place in forest modelling. Here it is described from the point of different visualisations methods and used technologies. Inputs that are necessary for the models but are often not available and need to be derived using specialised tools – various forms of data generators are presented too. Important perspectives and challenges of further development of forest models and visualisation technologies were specified as well.

Abstract:

Researchers using corpora can visualise their data and analyses using a growing number of tools. Visualisations are especially valuable in environments where researchers communicate and work with public-facing partners under the auspices of ‘knowledge exchange’ or ‘impact’, and corpus data are more available thanks to digital methods. However, although the field of corpus linguistics continues to generate its own range of techniques, it largely remains orientated towards finding ways for academics to communicate results directly with other academics rather than with or through groups outside universities. Also, there is a lack of discussion about how communication, motivations and values also feature in the process of making corpus data visible. My argument is that these sociocultural and practical factors also influence visualisation outputs alongside technical aspects. I draw upon two corpus-based projects about press portrayal of migrants, conducted by an intermediary organisation that links university researchers with users outside academia. Analysing these projects' visualisation outputs in their organisational and communication contexts produces key lessons for researchers wanting to visualise text; consider the aims and values of partners; develop communication strategies that acknowledge different areas of expertise; and link visualisation choices with wider project objectives.

Abstract:

Cascades appear in many applications, including biological graphs and social media analysis. In a cascade, a dynamic attribute propagates through a graph, following its edges. We present the results of a formal user study that tests the effectiveness of different types of cascade visualisations on node-link diagrams for the task of judging cascade spread. Overall, we found that a small multiples presentation was significantly faster than animation with no significant difference in terms of error rate. Participants generally preferred animation over small multiples and a hierarchical layout to a force-directed layout. Considering each presentation method separately, when comparing force-directed layouts to hierarchical layouts, hierarchical layouts were found to be significantly faster for both presentation methods and significantly more accurate for animation. Representing the history of the cascade had no significant effect. Thus, for our task, this experiment supports the use of a small multiples interface with hierarchically drawn graphs for the visualisation of cascades. This work is important because without these empirical results, designers of dynamic multivariate visualisations (in many applications) would base their design decisions on intuition with little empirical support as to whether these decisions enhance usability.

Abstract:

Mucus is a water-insoluble gel secreted by the gastrointestinal tract. It exists as a protective gel layer adherent to the epithelial surface of the stomach, small intestine and colon. The mucus gel is composed of 1–10% (w/v) mucin glycoprotein in a plasma-like fluid. Since the mucus gel is predominantly water, standard histological techniques dehydrate the mucus, making visualisation of the functional barrier difficult. Specialist techniques have been developed to enable visualisation of the intact mucus layer. A simple histological method using snap-frozen tissue, sectioned with a cryostat and stained with modified periodic acid-Schiff s/Alcian blue in mucus-preserving conditions will be described. A second powerfulin vivoanimal model is described which enables measurement of mucus secretion over time. The use of these two methods has allowed the characterisation of the normal mucus layer in the colon and the determination of how it is affected by disease and dietary intervention, in particular the effect of dietary fibre, and evidence that fibre deficiency results in colonic mucosal fragility is presented.

Abstract:

Abstract The paper demonstrates the feasibility of quantitative flow visualisation methods for investigation of transonic and supersonic flows. Two methods and their application for retrieving compressible flow field properties has been described: Background Oriented Schlieren (BOS) and Particle Image Velocimetry (PIV). Recently introduced BOS technique extends the capabilities of classical Schlieren technique by use of digital image processing and allow to measure density gradients field. In the presented paper a review of applications of BOS technique has been presented. The PIV is well established technique for whole field velocity measurements. This paper presents application of PIV for determination of the shock wave position above airfoil in transonic flow regime. The study showed that application of quantitative flow visualisation techniques allows to gain new insights on the complex phenomenon of supersonic and transonic flow over airfoils like shock-boundary layer interaction and shock induced flow separation.

Abstract:

The Database of Topographic Objects (DTO) is the official database of Poland for collecting and providing spatial data with the detail level of a topographic map. Polish national DTOs manage information about the spatial location and attribute values of geographic objects. Data in the DTO are the starting point for geographic information systems (GISs) for various central and local governments as well as private institutions. Every set of spatial data based on measurement-derived data is susceptible to uncertainty. Therefore, the widespread awareness of data uncertainty is of vital importance to all GIS users. Cartographic visualisation techniques are an effective approach to informing spatial dataset users about the uncertainty of the data. The objective of the research was to define a set of methods for visualising the DTO data uncertainty using expert know-how and experience. This set contains visualisation techniques for presenting three types of uncertainty: positional, attribute, and temporal. The positional uncertainty for point objects was presented using visual variables, object fill with hue colour and lightness, and glyphs placed at map symbol positions. The positional uncertainty for linear objects was presented using linear object contours made of dotted lines and glyphs at vertices. Fill grain density and contour crispness were employed to represent the positional uncertainty for surface objects. The attribute value uncertainty and the temporal uncertainty were represented using fill grain density and fill colour value. The proposed set of the DTO uncertainty visualisation methods provides a finite array of visualisation techniques that can be tested and juxtaposed. The visualisation methods were comprehensively evaluated in a survey among experts who use spatial databases. Results of user preference analysis have demonstrated that the set of the DTO data uncertainty visualisation techniques may be applied to the full extent. The future implementation of the proposed visualisation methods in GIS databases will help data users interpret values correctly.

Abstract:

A good software architecture design is crucial in successfully realising an object-oriented analysis (OOA) specification with an object-oriented design (OOD) model that meets the specification's functional and non-functional requirements. Most CASE tools and software architecture design notations do not adequately support software architecture modelling and analysis, integration with OOA and OOD methods and tools, and high-level, dynamic architectural visualisations of running systems. We describe SoftArch, an environment that provides flexible software architecture modelling using a concept of successive refinement and an extensible architecture meta-model. SoftArch provides extensible analysis tools enabling developers to analyse their architecture model properties. Run-time visualisation of systems uses dynamic annotation and animation of high-level architectural modelling views. SoftArch is integrated with a component-based CASE tool and run-time monitoring tool, and has facilities for 3rd party tool integration through a common exchange format. This paper discusses the motivation for SoftArch, its modelling, analysis and dynamic visualisation capabilities, and its integration with various analysis, design and implementation tools.

Abstract:

Large radio surveys such as those proposed for several SKA pathfinder and precursor telescopes require (automated) source-finding algorithms that are highly reliable, complete, and fast. Similarly, sophisticated visualisation tools are needed to explore the resulting survey data together with their multi-wavelength counterparts.In this PASA Special Issue on Source Finding and Visualisation, several advanced source-finding algorithms, including novel methods for radio continuum, polarisation and spectral line surveys are described, tested and compared. The process of finding sources can be considered one of many important steps (e.g., pre-processing, source finding and characterisation, cataloguing/post-processing) in the production of astronomical source catalogues, on which much of the survey science is based.The Australian SKA Pathfinder (ASKAP), equipped with novel Chequerboard phased array feeds, will be a powerful 21-cm survey machine. For the large volumes of ASKAP data, a special version of Duchamp, called Selavy, is being developed in consultation with the ASKAP survey science teams (Whiting & Humphreys 2012). Extensive testing and comparisons of existing and new source-finding algorithms were carried out for this PASA Special Issue and are presented by Westmeier, Popping & Serra (2012), Westerlund, Harris & Westmeier (2012), Popping et al.

An overview on spectral line source finding and visualisation is given by Koribalski (2012), while Hassan, Fluke & Barnes (2012) look into real-time 3D volume rendering of large (Tbytes) astronomical data cubes.

Abstract:

Meanings Offering three texts-as-images (to illustrate photogrammar), a sketch is made of analogies between Foucault's pastoral powers and the grammar of the picturesque and the picturable as part of an investigation of the dialexis of Authority and Difference. Picturing, it is argued, works not only in the depicting but in the photogrammar of what and whom is shown how, they thus encourage ways of seeing and saying more general than any one re-presentation. Critique begins with the stress on these selecting and dividing practices but must then move to a study of orthogonality (who is projecting whom) as a particular form of Authority in relation to Difference. Comme toujours, distanciation that makes this feature of cartography clear begins with making strange what is obvious (hence innocence, naivété) and being a little gauche (hence stupidity). Memories We forget, or at least I do. In close analogy with W. B. Yeats' poem for ‘Unknown Instructors’, I acknowledge here the influence of Jean Luc Godard and, in part through him, Ludwig Wittgenstein. Reviewing Godard's work, in a retrospective in Toronto (February-March, 1988) I was struck by the meanings and questions and methods I had taken from his work, especially from Les Carabiniers (1962) in the closing scene where these Rifle- men return with their booty: their postcards acting as the real; equally from the Godard-Gorin Letter to Jane (1972), how the struggle for new questions instead of old answers has to be a difference done differently. But, sentimentally, nothing surpasses (and in this reviewing I wept again) Alphaville (1965) for its insight into Authority as grammar, and as Terror. Thank you.

Abstract:

The numbers of online purchases and electronic banking transactions have increased substantially in the era of electronic business and mobile commerce. These online financial activities have attracted a special web threat called “phishing” that targets Internet users by seeking their credentials in order to access their financial information. Phishing involves impersonating a legitimate website by creating a visually similar fake website to deceive users. In the last decade different solutions to fight phishing that are primarily based on educating users, user’s experience, search methods, machine learning and features similarity have been developed. This paper combines computational intelligence along with user’s experience approaches to develop an anti-phishing visualisation method. Our method employs effective features chosen following thorough analysis on features scores generated by Correlation Feature Set and Information Gain processing techniques. We validate our anti-phishing features using classification systems produced by rule induction data mining approach. False positives, false negatives and phishing detection rate are the basis of evaluating the classification systems to measure our anti-phishing methods features’ integrity.

Abstract:

With the explosion of Internet of Things (IoT) worldwide, there is an increasing threat from malicious software (malware) attackers that calls for efficient monitoring of vulnerable systems. Large amounts of data collected from computer networks, servers, and mobile devices need to be analysed for malware proliferation. Effective analysis methods are needed to match with the scale and complexity of such a data-intensive environment. In today’s Big Data contexts, visualisation techniques can support malware analysts going through the time-consuming process of analysing suspicious activities thoroughly. This paper takes a step further in contributing to the evolving realm of visualisation techniques used in the information security field. The aim of the paper is twofold: (1) to provide a comprehensive overview of the existing visualisation techniques for detecting suspicious behaviour of systems and (2) to design a novel visualisation using similarity matrix method for establishing malware classification accurately. The prime motivation of our proposal is to identify obfuscated malware using visualisation of the extended x86 IA-32 (opcode) similarity patterns, which are hard to detect with the existing approaches. Our approach uses hybrid models wherein static and dynamic malware analysis techniques are combined effectively along with visualisation of similarity matrices in order to detect and classify zero-day malware efficiently. Overall, the high accuracy of classification achieved with our proposed method can be visually observed since different malware families exhibit significantly dissimilar behaviour patterns.

Abstract:

Abstract. Network analysis has become an important approach in studying complex spatiotemporal behaviour within geophysical observation and simulation data. This new field produces increasing numbers of large geo-referenced networks to be analysed. Particular focus lies currently on the network analysis of the complex statistical interrelationship structure within climatological fields. The standard procedure for such network analyses is the extraction of network measures in combination with static standard visualisation methods. Existing interactive visualisation methods and tools for geo-referenced network exploration are often either not known to the analyst or their potential is not fully exploited. To fill this gap, we illustrate how interactive visual analytics methods in combination with geovisualisation can be tailored for visual climate network investigation. Therefore, the paper provides a problem analysis relating the multiple visualisation challenges to a survey undertaken with network analysts from the research fields of climate and complex systems science. Then, as an overview for the interested practitioner, we review the state-of-the-art in climate network visualisation and provide an overview of existing tools. As a further contribution, we introduce the visual network analytics tools CGV and GTX, providing tailored solutions for climate network analysis, including alternative geographic projections, edge bundling, and 3-D network support. Using these tools, the paper illustrates the application potentials of visual analytics for climate networks based on several use cases including examples from global, regional, and multi-layered climate networks.

This new field produces increasing amounts of large geo-referenced networks to be analysed. Particular focus lies currently on the network analysis of the complex statistical interrelationship structure within climatological fields. The standard procedure for such network analyses is the extraction of network measures in combination with static standard visualisation methods. Existing interactive visualisation methods and tools for geo-referenced network exploration are often either not known to the analyst or their potential is not fully exploited. To fill this gap, we illustrate how interactive visual analytics methods in combination with geovisualisation can be tailored for visual climate network investigation. Therefore, the paper provides a problem analysis, relating the multiple visualisation challenges with a survey undertaken with network analysts from the research fields of climate and complex systems science. Then, as an overview for the interested practitioner, we review the state-of-the-art in climate network visualisation and provide an overview of existing tools. As a further contribution, we introduce the visual network analytics tools CGV and GTX, providing tailored solutions for climate network analysis, including alternative geographic projections, edge bundling, and 3-D network support. Using these tools, the paper illustrates the application potentials of visual analytics for climate networks based on several use cases including examples from global, regional, and multi-layered climate networks.

Abstract:

Visual analytics and visualisation can leverage the human perceptual system to interpret and uncover hidden patterns in big data. The advent of next-generation sequencing technologies has allowed the rapid production of massive amounts of genomic data and created a corresponding need for new tools and methods for visualising and interpreting these data. Visualising genomic data requires not only simply plotting of data but should also offer a decision or a choice about what the message should be conveyed in the particular plot; which methodologies should be used to represent the results must provide an easy, clear, and accurate way to the clinicians, experts, or researchers to interact with the data. Genomic data visual analytics is rapidly evolving in parallel with advances in high-throughput technologies such as artificial intelligence (AI) and virtual reality (VR). Personalised medicine requires new genomic visualisation tools, which can efficiently extract knowledge from the genomic data and speed up expert decisions about the best treatment of individual patient’s needs. However, meaningful visual analytics of such large genomic data remains a serious challenge. This article provides a comprehensive systematic review and discussion on the tools, methods, and trends for visual analytics of cancer-related genomic data. We reviewed methods for genomic data visualisation including traditional approaches such as scatter plots, heatmaps, coordinates, and networks, as well as emerging technologies using AI and VR. We also demonstrate the development of genomic data visualisation tools over time and analyse the evolution of visualising genomic data.

Abstract:

Browsing concept lattices from Formal Concept Analysis (FCA) becomes a problem as the number of concepts can grow significantly with the number of objects and attributes. Interpreting the lattice through direct graph-based visualisation of the Hasse diagram rapidly becomes difficult and more synthetic representations are needed. In this work the authors propose an approach to simplify concept lattices by extracting and visualising trees derived from them. The authors further simplify the browse-able trees with two reduction methods: fault-tolerance and concept clustering.

Abstract:

Brain atlases have a wide range of use from education to research to clinical applications. Mathematical methods as well as computational methods and tools play a major role in the process of brain atlas building and developing atlas-based applications. Computational methods and tools cover three areas: dedicated editors for brain model creation, brain navigators supporting multiple platforms, and atlas-assisted specific applications. Mathematical methods in atlas building and developing atlas-aided applications deal with problems in image segmentation, geometric body modelling, physical modelling, atlas-to-scan registration, visualisation, interaction and virtual reality. Here I overview computational and mathematical methods in atlas building and developing atlas-assisted applications, and share my contribution to and experience in this field.

Abstract:

Much like Walter Benjamin's analysis of the Parisian arcades during the interwar years of the early 20th century, emerging methods of seeing interior spaces reveal a deeper gaze into the contextual, material, and phenomenological conditions that produce more nuanced visions of interiority. A collective consciousness surrounding these constructed narratives is reflected in charged associations with the most salient imperatives of our time—globalisation, resource depletion, ecological degradation, and political instability—as well as their corresponding effects on the built environment. These visual provocations have incrementally percolated up to embody an expanding field of design activism for educators, theorists, practitioners, and students. How do these avant-garde techniques operate? What do they reveal about socio-political, economic, and consumptive forces shaping the global built environment? How do these speculative methods offer more critical ways to communicate dynamic conditions?

Abstract:

AbstractThis paper discusses and demonstrates the use of visualisation and visual methods in the description and analysis of the learning trajectories of long-term learners and users of an additional language (in this case, Mandarin Chinese). It draws on a longitudinal case study that investigated how the dynamic complexity and variety of long-term trajectories of learning an additional language can be described, represented and interpreted. The specific focus of this article is the visual timeline analysis method used in the study. The timeline method offers an innovative way of representing and comparing individual language learning chronologies in visual format. By progressively layering, along a time axis, visualisations of longitudinal data relating to a number of different aspects of the learning context, the method allows a simultaneous overview of multiple aspects of development over time. These information-rich representations can reveal insights into patterns of choices and development over time which are not easily perceived in text-based accounts.

Abstract:

The article is dedicated to the transformation of learning processes. The causal reasons for the widespread use of the fractal approach in the use of techniques and methods of visualising educational information are considered. The specifics of the use of fractal movement in the organisation of the educational process are described. The role and place of the teacher in the management of transfer and disclosure processes is noted. The fractal organisation of the learning route algorithm is characterised by a markedly deep determinism of the factors that determine the purpose and result of learning. The text notes the conditions of filling the thesaurus of the learner, improving its intellectual property in the form of transmission, assimilation and rejection of information. The elements of the thesaurus formed in the fractal educational field orient both the teacher and the learner to an extended view of a qualitatively in-depth approach to presenting in a specific unity of elements of visualised educational material. The connection between the individual abilities of the teacher and the potential of the learner is been traced. The conditions of the optimal combination of information flow and abilities of the learner, determining the success of training, are highlighted. Positive experience of the implementation of the proposed provisions of the educational process implies further analysis of the mechanisms and procedures of the fractal educational space.

Abstract:

One of the most important tasks of microscopy is to provide information about structures in their natural state. Since most life science microscopy procedures require fixation, dehydration, drying, and sectioning, diverse artefacts are unavoidable. It is also possible to dehydrate the water content of a specimen by freeze-drying. However, even relatively stable surface structures are changed during such treatments. Methods of liquid substitution and freezing-substitution show good results for biological specimens with a waxy solid coverage (Ensikat and Barthlott, 1993) and soft specimens in a mechanically deformed state (Gorb et al., 2000).However, all these methods have certain restrictions for some types of specimens. For example, there are numerous biological surfaces covered with secretory fluids. Some specimens bear solid waxy coverings, which can be partly dissolved and washed out in organic solvents, such as ethanol, acetone, or propylenoxide. Often one would like to visualise dynamic processes (growth, deformation, or crystallisation) under environmental conditions, but at the high resolution in the SEM.

Abstract:

This article sets a framework for computer-based visualisations of cultural heritage sites. The project focuses on a workflow for a visualisation illustrated on a specific solution for the site of Çukuriçi Höyük, a tell settlement in Turkey. With the virtual presentation, an interdisciplinary research group tries to offer complex scientific results to the general public as well as to experts. The team utilised data acquisition and communication techniques, interpretative approaches, and dissemination methods. The three-dimensional (3D) outcome is based on a large amount of scientific data, usually available only via analogue or digital publications for a specialised audience. The work focused on constructed and personal authenticity to reach the viewer’s feelings. As an interpretative narrative, the daily lives of the inhabitants were selected. A communication plan was constructed, and a video animation with narration and a musical background was selected as the most appropriate communication tool. The movie was divided into four chapters (Introduction, Neolithic Period, Chalcolithic Period and Early Bronze Age Period). A separate webpage was designed to provide additional information when the video is viewed online. The webpage was divided into tabs that describe each chapter and three additional topics (Visualisation Process, Further Reading, and Credits). The video was shared in different settings, e.g. at public talks and on social media. The process resulted in a complex workflow that consists of several stages: data acquisition, first interpretation, 3D model creation, communication plan, second interpretation, 3D model adjustment, and dissemination output. Each stage of the workflow serves as an example to show the types of nodes these parts can include. The result is a flexible framework with predefined process stages, which can be re-used for similar projects.Highlights:<ul><li>Computer-aided visualisations bring hidden cultural heritage to life –an individual outcome for Çukuriçi Höyük, a tell settlement in Turkey.</li><li>The interdisciplinary team combined data acquisition and communication techniques, interpretative approaches, and dissemination methods for achieving the best result.</li><li>Integrative framework optimises the information and communication potential of virtual visualisations with the help of pre-defined workflow stages.</li></ul>

Abstract:

Purpose – Conducting academic searches within online digital libraries can be a difficult task due to the complexity of the searcher’s information need. The interfaces for such digital libraries commonly use simple search features that provide limited support for the fundamental strategies that academic searchers employ. The authors have developed a novel visualisation interface called Bow Tie Academic Search to address some of these shortcomings, and present in this paper the findings from a user evaluation. The paper aims to discuss these issues. Design/methodology/approach – A controlled laboratory study was conducted to compare a traditional search interface to Bow Tie Academic Search. In total, 24 graduate students were recruited to perform academic searches using the two candidate interfaces, guided by specific sub-tasks that focus on citation and keyword analysis strategies. Findings – Although the use of the core visualisation and exploration features did not reveal differences in retrieval effectiveness or efficiency, the query refinement features were found to be effective. Strongly positive impressions of usefulness and ease of use of all aspects of the system were reported, along with a preference for using Bow Tie Academic Search for academic search tasks. Originality/value – This study provides insight into the potential value for providing visual and interactive interfaces for supporting academic search tasks and strategies. While the quantitative improvements over the traditional search interface were minimal, the qualitative measures illustrate the value of Bow Tie Academic Search.

Abstract:

According to a commonly accepted view, the process of decision making comprises three major phases: intelligence (situation analysis and problem recognition), design (finding possible variants of problem solution), and choice (evaluation of the options and selection of the most appropriate ones). It is widely recognised that exploratory data visualisation is very helpful during the first phase of the decision-making process, while the other phases require different software tools. In particular, the choice phase is typically supported by various computational methods that find appropriate trade-offs among multiple conflicting criteria taking into account user-specified priorities. Visualisation plays a limited role: in the best case, it is used to represent the final results of the computations. We argue that conscious, well-substantiated choice requires a more extensive use of exploratory visualisation facilities, which need to be properly coordinated with the computational multi-criteria decision support methods. Extremely important is a high degree of user interactivity, which allows the user to probe the robustness and quality of computationally derived solutions. We suggest several mechanisms for linking and coordinating visual exploratory tools with two types of computational methods differing in the sort of output they produce. We demonstrate the use of this dynamic link with an example of a real spatially related decision problem.

Abstract:

This editorial introduces the subject matter of the thematic issue, which includes a diverse collection of contributions from authors in various disciplines including, history, architecture, planning, sociology and geography. Within the context of mediatisation processes—and the increased use of ever-expanding I&C technologies—communication has undergone profound changes. As such, this thematic issue will discuss how far (digital) media tools and their social uses in urban design and planning have impacted the visualisation of urban imaginations and how urban futures are thereby communicatively produced. Referring to an approach originating from the media and communication sciences, the authors begin with an outline of the core concepts of mediatisation and digitalisation. They suggest how the term ‘visualisation’ can be conceived and, against this background, based upon the sociological approach of communicative constructivism, a proposal is offered, which diverges from traditional methods of conceptualising visualisations: Instead, it highlights the need for a greater consideration towards the active role of creators (e.g., planners) and recipients (e.g., stakeholders) as well as the distinctive techniques of communication involved (e.g., a specific digital planning tools). The authors in this issue illustrate how communicative construction, particularly the visual construction of urban futures, can be understood, depending upon the kind of social actors as well as the means of communication involved. The editorial concludes with a summary of the main arguments and core results presented.
