PublicationVisual Replay Methodology: A Mixed Methods Approach for Group Discussion AnalysisIn this article, we propose an innovative mixed methods research (MMR) technique and discuss its theory and applications. The visual replay methodology (VRM) is a new graphic way to investigate the discourse patterns during software-aided small group discussions. A visually supported conversation is recorded through screen capturing and replayed to reconstruct how the discussion has unfolded. The VRM responds to the “integration challenge” that the MMR community is facing—by employing the power of visualization, data integration is leveraged to a new level, where visual synergy gains enable a “value-added” research outcome. By employing multigenre integration and a moderately pragmatic approach, the VRM reduces the researcher–subject power-relation gap and contributes to some long-standing MMR debates regarding reflexivity and participation.Type: journal articleJournal: Journal of Mixed Methods ResearchVolume: 13Issue: 1

PublicationVisual Design Thinking: A Collaborative Dimensions framework to profile visualisationsDesign Thinking is predominantly visual: a variety of visualisations e from sketches to analytic diagrams e can support designers’ work. Each visual format has affordances that constrain and enable specific cognitive and collaborative actions: how can we describe, select and design visualisations for supporting specific phases of the design process? By integrating literature from related domains we developed a “Collaborative Dimensions of Visualisations framework”, which allows to distinguish seven traits of visualisations: Structural Restrictiveness, Content Modifiability, Directed Focus, Perceived Finishedness,Outcome Clarity, Visual Appeal and Collaboration Support. Each dimension is described and an illustrative example is provided. The framework is a pragmatic and theoretically grounded discussion tool aimed at helping designers make more informed decisions regarding the visualisations they work with.Type: journal articleJournal: Design StudiesVolume: 63Issue: July 2019

PublicationThe collaborative dimensions of argument maps: A socio-visual approachThis paper examines the collaborative use of visual argument maps in the context of argument production in organizations. Argument maps are highly multimodal, as their use involves the combination of diagrams, text elements, as well as spoken statements. In this theoretical piece, we apply a Collaborative Dimensions framework to argument maps that can be used to better design, understand, evaluate, and use argument maps in collaborative settings for decision making purposes. Specifically, our conceptual framework – derived from interdisciplinary perspectives – takes into consideration how the visual dimensions of argument maps have a bearing on the social interactions of people involved in a complex argumentation process. We posit that cognitive dimensions of argument maps need to be enriched with additional communicative and collaborative dimensions in order to foster a more widespread adoption of argument mapping in organizational decision making. In our socio-visual approach to argument mapping, we thus distinguish the following seven dimensions: Visual Insight, Outcome Clarity, Directed Focus, Perceived Finishedness, Visual Appeal, Content Modifiability, and Collaboration Support. We illustrate the use of the framework as an evaluation tool and analyze three different approaches to argument mapping with the help of the seven dimensions. In this way, the framework can be used to improve collaborative argument mapping. Our contribution thus lies in proposing an interdisciplinary and theoretically grounded set of factors to augment the quality of argument maps, both from a process and a results perspective. In this manner we hope to contribute to the theory of argumentation through the rich notion of “collaborative dimensions,” as well as further the practice of collaborative argument production through a more reflective and systematic use of interactive argument visualization.Type: journal articleJournal: SemioticaVolume: 220

PublicationFacilitating Culturally Diverse Groups with Visual Templates in Collaborative Systems: Increasing Structuration to Improve PrecisionPurpose – The use of visual templates has proven instrumental in supporting group meetings. This study explores whether visual templates enable culturally diverse groups to achieve greater task precision in face-to-face meetings. Design/methodology/approach – Building on Adaptive Structuration Theory (AST), it is argued that visual templates provide structuration for face-to-face meetings, even more so when they are embedded in computer-supported collaborative systems. In particular, it is hypothesized that the higher the degree of structuration imposed by visual templates, the higher the degree of task precision will be. It is also hypothesized that this relationship is positively moderated by group cultural diversity: higher cultural diversity will further sustain the positive effects of visual templates that provide higher structuration. Findings – Results of an experiment with 229 managers from 49 countries confirm that facilitating groups with visual templates embedded in a computer-supported collaborative system significantly increases task precision at high levels of cultural diversity. Research limitations/implications – This study contributes to Positive Organizational Scholarship (POS) by investigating the use of visual templates as a contingency factor that increases performance – specifically task precision – of co-located, culturally diverse groups. Practical implications – Results indicate that visual templates embedded in a computer-supported collaborative system are an effective method for increasing task precision in face-to-face meetings of culturally diverse groups. Originality/value – Theories from information systems and visualization are integrated into cross-cultural management with a view to sustaining the effectiveness of culturally diverse groups. The study sample is characterized by highly culturally diverse groups interacting in face-to-face meetings.Type: journal articleJournal: Cross Cultural & Strategic ManagementVolume: 24Issue: 1

PublicationNew Brand Logo Design: Customers’ Preference for Brand Name and IconBrand logos can provide affective reactions before any promotional activity is carried out. This is particularly relevant for start-ups that might not have the budget for branding activities. Extant research is predominantly based on theoretical models. By contrast, we adopted a customer-based approach with a novel methodology—multiple picture sorting—to investigate the most relevant characteristics that customers identify for differentiating novel logos, and compared them with existing theories. Ninety-three subjects were asked to classify unknown logos according to criteria of their choice. Most customers clustered logos into: (1) composed of brand icon and/or name and (2) coloured or black logos. We then used experiments to test whether the logo characteristics identified by customers make a difference in logos’ attractiveness. Results show that logos composed of an icon plus a brand name are perceived as significantly more attractive than logos made of one component only, and that black logos are perceived as more attractive than coloured logos. Thus, customers-identified logo characteristics can guide entrepreneurs in designing and selecting logos for novel brands. This study adds to current theory by showing that one of the most relevant logo characteristics—brand icon and/or name—has rarely been investigated.Type: journal articleJournal: The journal of brand management : an international journalVolume: 24Issue: 5

PublicationWe walk the line: Icons provisional appearances on virtual whiteboards trigger elaborative dialogue and creativityCollaborative groupwork is a key creativity tool in industry. Digital Creativity Support Systems (CSS) have become a critical catalyst of distributed creative processes. Under laboratory conditions, this interaction design study uses an experiment to investigate the impact of apparent icon finishedness as a social affordance for elaborative dialogue, and enhanced creativity. The experiment examines the idea generation processes of 37 pairs of active managers using a synchronous CSS. Apparent finishedness is a purely presentational factor - it is completely separate from the actual substance of an idea. The results show that presenting ideas with icons made of sketchy natural lines with low perceived finishedness encourages elaborative dialogue and creativity. Low perceived finishedness icons functioned as a social affordance - they afforded the social behaviour of building upon each other’s ideas as well as more creative idea generation. This is the first study to quantitatively examine the perceived finishedness of icons. This study shows that minor changes in visual treatments significantly impact creative processes and outcomes. As co-constructive interaction is central to many collaborative behaviours across working and learning, this study has clear implications for the subtle encouragement of co-construction in computer-mediated communication.Type: journal articleJournal: Computers in Human BehaviorVolume: 63

PublicationUnderstanding the Impact of Visual Representation Restrictiveness on Experience Sharing: an Experimental AssessmentThis study investigates the effects of the restrictiveness of visuals on the communication process and outcome in small groups. Visual restrictiveness is conceived as the constraints imposed by a graphic template on the process of knowledge work. Through an experiment with ninety six experienced professionals we test the impact of a medium and a high level of visual restrictiveness compared to a control condition. As predicted, the results show that a medium level of visual restrictiveness, embodied in a grid layout, leads to higher experience sharing effectiveness. The impact is mediated by the structural pattern of appropriation of the interactive graphical template (assessed with content analysis). The implications of this study include extending the benefits and applications of visual representations to support group communication and the development (and testing) of the concept of visual restrictiveness.Type: journal articleJournal: Journal of Visual Languages and ComputingVolume: 31Issue: Part A

PublicationExtending Tam to Information Visualization: A Framework for EvaluationStudies on the evaluation of information visualization techniques are flourishing, and related methodologies have been discussed in a growing number of recent studies. Yet, these evaluations concentrate mostly on usability measures and cognitive evaluations. In contrast, this contribution focuses on the various factors that drive the adoption of information visualization techniques. The Technology Acceptance Model and the Diffusion of Innovations theory are deployed to develop a framework for evaluating information visualization adoption. These seminal theories are extended and adapted to Information Visualization, resulting into a framework with three main dimensions: perceived ease of use, perceived usefulness, and perceived authority. The application of this theoretically-based evaluation framework is illustrated through positive and negative examples. As many visualization solutions have not achieved a wide use, the question of which factors foster their adoption seems to be a particularly relevant yet under-researched topic.Type: journal articleJournal: Electronic Journal of Information System EvaluationVolume: 18Issue: 1
