“…Sometimes, however, they can provide benefits by convincing gatekeepers to open the door for wide deployment of visualization, as in the design study of heart disease diagnosis by Borkin et al [11] or in our own MostVis project [73,76].…”

Abstract-Design studies are an increasingly popular form of problem-driven visualization research, yet there is little guidance available about how to do them effectively. In this paper we reflect on our combined experience of conducting twenty-one design studies, as well as reading and reviewing many more, and on an extensive literature review of other field work methods and methodologies. Based on this foundation we provide definitions, propose a methodological framework, and provide practical guidance for conducting design studies. We define a design study as a project in which visualization researchers analyze a specific real-world problem faced by domain experts, design a visualization system that supports solving this problem, validate the design, and reflect about lessons learned in order to refine visualization design guidelines. We characterize two axes-a task clarity axis from fuzzy to crisp and an information location axis from the domain expert's head to the computer-and use these axes to reason about design study contributions, their suitability, and uniqueness from other approaches. The proposed methodological framework consists of 9 stages: learn, winnow, cast, discover, design, implement, deploy, reflect, and write. For each stage we provide practical guidance and outline potential pitfalls. We also conducted an extensive literature survey of related methodological approaches that involve a significant amount of qualitative field work, and compare design study methodology to that of ethnography, grounded theory, and action research.

“…3), one might hypothesize that the closer the visualization is to 'reality', the easier it may be for the urban designers as users to comprehend what is being proposed and make decisions (Hayek et al, 2011;Herbert & Chen, 2014). On the other hand, even though it might present certain advantages in some cases, such as revealing information that may not have been otherwise visible (Li et al, 2010), or people might prefer it for a set of tasks (Çöltekin, et al, 2015) there is strong evidence that for reading plots (Dall'Acqua et al, 2013), or detecting anomalies (Borkin et al, 2011), 3D visualizations might rather hinder their users than help them. Various reasons have been proposed for the causes of the failures with 3D visualizations.…”

ABSTRACT:Whether and when should we show data in 3D is an on-going debate in communities conducting visualization research. A strong opposition exists in the information visualization (Infovis) community, and seemingly unnecessary/unwarranted use of 3D, e.g., in plots, bar or pie charts, is heavily criticized. The scientific visualization (Scivis) community, on the other hand, is more supportive of the use of 3D as it allows 'seeing' invisible phenomena, or designing and printing things that are used in e.g., surgeries, educational settings etc. Geographic visualization (Geovis) stands between the Infovis and Scivis communities. In geographic information science, most visuo-spatial analyses have been sufficiently conducted in 2D or 2.5D, including analyses related to terrain and much of the urban phenomena. On the other hand, there has always been a strong interest in 3D, with similar motivations as in Scivis community. Among many types of 3D visualizations, a popular one that is exploited both for visual analysis and visualization is the highly realistic (geo)virtual environments. Such environments may be engaging and memorable for the viewers because they offer highly immersive experiences. However, it is not yet well-established if we should opt to show the data in 3D; and if yes, a) what type of 3D we should use, b) for what task types, and c) for whom. In this paper, we identify some of the central arguments for and against the use of 3D visualizations around these three considerations in a concise interdisciplinary literature review.

“…As with cartography, there is increasing emphasis on user-centered evaluation in the related fields of information visualization and scientific visualization as the essential mechanism for determining whether an interactive design 'works' (e.g. Barkhuus & Rode, 2007;Borkin et al, 2011;Isenberg, Isenberg, Chen, Sedlmair, & Möller, 2013;Lam, Bertini, Isenberg, Plaisant, & Carpendale, 2012). But, which empirical methods should we use, and at what times during design?…”

The possibility of digital interactivity requires us to reenvision the map reader as the map user, and to address the perceptual, cognitive, cultural, and practical considerations that influence the user's experience with interactive maps and visualizations. In this article, we present an agenda for empirical research on this user and the interactive designs he or she employs. The research agenda is a result of a multi-stage discussion among international scholars facilitated by the International Cartographic Association that included an early round of position papers and two subsequent workshops to narrow into pressing themes and important research opportunities. The focus of our discussion is epistemological and reflects the wide interdisciplinary influences on user studies in cartography. The opportunities are presented as imperatives that cross basic research and user-centered design studies, and identify practical impediments to empirical research, emerging interdisciplinary recommendations to improve user studies, and key research needs specific to the study of interactive maps and visualizations.
