context of use later prototypes requirements early prototypes Fig. 1. Graphical approaches used in a long-term investigation into using human-centred methods in geovisualization design include, from left: keyword in context; card sorting; requirements and design concept sketching; and wireframe, paper and digital prototypes.Abstract-Working with three domain specialists we investigate human-centered approaches to geovisualization following an ISO13407 taxonomy covering context of use, requirements and early stages of design. Our case study, undertaken over three years, draws attention to repeating trends: that generic approaches fail to elicit adequate requirements for geovis application design; that the use of real data is key to understanding needs and possibilities; that trust and knowledge must be built and developed with collaborators. These processes take time but modified human-centred approaches can be effective. A scenario developed through contextual inquiry but supplemented with domain data and graphics is useful to geovis designers. Wireframe, paper and digital prototypes enable successful communication between specialist and geovis domains when incorporating real and interesting data, prompting exploratory behaviour and eliciting previously unconsidered requirements. Paper prototypes are particularly successful at eliciting suggestions, especially for novel visualization. Enabling specialists to explore their data freely with a digital prototype is as effective as using a structured task protocol and is easier to administer. Autoethnography has potential for framing the design process. We conclude that a common understanding of context of use, domain data and visualization possibilities are essential to successful geovis design and develop as this progresses. HC approaches can make a significant contribution here. However, modified approaches, applied with flexibility, are most promising. We advise early, collaborative engagement with data -through simple, transient visual artefacts supported by data sketches and existing designs -before moving to successively more sophisticated data wireframes and data prototypes.

“…The complicated and multivariate tools of the ESTAT were not used commonly with the users. The most interesting finding of this stage was that the users did not face a lot of interaction problems, and this indicated improvement in development and refinement of the tool [17]. …”

BackgroundAnalyzing and visualizing health-related databases using Geographic Information Systems (GISs) becomes essential in controlling many public health problems.ObjectivesTo explore the perception and preferences of public health professionals (PHPs) about the usability of GISs in public health fieldMethodsFor this scoping review, the investigators searched Medline Ovid, PubMed, IEEE, Scopus, and GeoBase databases. A total of 105 articles were identified. Nine articles met the inclusion criteria.ResultsIterative evaluations, training, and involvement of GIS end users are productive in GIS usability. More methodologies are needed to support the validity of GIS usability studies. The exchange of GIS technology impacts public health policy and research positively.DiscussionPHPs are aware of the use of GISs in the public health field, and the exchange of visualized health data in determining inequalities and inaccessibility issues.ConclusionGISs are essential to control public health problems, if the related health datasets are analyzed carefully and if the mapping reports are extensively evaluated and interpreted.

“…This suits demonstration and chauffeuring well because functionality is only revealed when required; a fact positively commented upon by one of the participants in our evaluation. There is evidence that cluttered user interfaces can detract from the data being shown [40] and that aesthetics can have a significant effect on user experience [6]. These considerations have strongly influenced our design.…”

“…We expected that some of the variation presented would be well-known to participants. This was deliberate, as confirming 'knowns' is an important step in gaining confidence in using visualization [40]. In the case of Leicestershire County Council, where four analysts took part, this was run as a group seminar where participants were encouraged to ask questions, offer their perspectives and discuss the data and methods.…”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Abstract-Geodemographic classifiers characterise populations by categorising geographical areas according to the demographic and lifestyle characteristics of those who live within them. The dimension-reducing quality of such classifiers provides a simple and effective means of characterising population through a manageable set of categories, but inevitably hides heterogeneity, which varies within and between the demographic categories and geographical areas, sometimes systematically. This may have implications for their use, which is widespread in government and commerce for planning, marketing and related activities. We use novel interactive graphics to delve into OAC -a free and open geodemographic classifier that classifies the UK population in over 200,000 small geographical areas into 7 super-groups, 21 groups and 52 sub-groups. Our graphics provide access to the original 41 demographic variables used in the classification and the uncertainty associated with the classification of each geographical area on-demand. It also supports comparison geographically and by category. This serves the dual purpose of helping understand the classifier itself leading to its more informed use and providing a more comprehensive view of population in a comprehensible manner. We assess the impact of these interactive graphics on experienced OAC users who explored the details of the classification, its uncertainty and the nature of between -and within -class variation and then reflect on their experiences. Visualization of the complexities and subtleties of the classification proved to be a thought-provoking exercise both confirming and challenging users' understanding of population, the OAC classifier and the way it is used in their organisations. Users identified three contexts for which the techniques were deemed useful in the context of local government, confirming the validity of the proposed methods. Permanent repository link
