Interacting with Visualizations

Abstract

In human-media interactions, visualizations occur in a large variety of forms. However, they remain but a single form of possible feedback towards a user. In this chapter it is argued that human-centered visualization is a fundamental part of human-media interaction and vice versa. To that end, the focus in this chapter lies first on the more general topic of interaction research, thus providing a solid literary ground for the rest of this chapter (Section 3.1). In Section 3.2 the focus shifts towards the question how a display technology influences the way(s) in which interaction with visualization takes place. This path is then broadened in Section 3.3 by focusing on approaches towards interacting multimodally with visualizations. To that end a chronological overview of developments in that field is given, thus providing an insight of trends and required steps in realizing multimodal interactions. Also, future work in this field is deducted from literature and those development trends. Fourthly, Section 3.4 describes the issues at hand for effectively applying visualizations in group-based collaborative and distributed environments. The aim in this chapter is to provide an overview of developments and the current state-of-the-art of approaches in which visualization supports the human-machine interaction process and vice versa. For that, this chapter is finalized with a short summary of issues to deal with while designing interaction for visualization. In addition current and future challenges in interacting with visualizations will be discussed.1 "An Agent can be a physical or virtual entity that can act, perceive its environment (in a partial way) and communicate with others, is autonomous and has skills to achieve its goals and tendencies." [253] 2 When speaking of an avatar, one refers to an Embodied Conversational Agent that typically exhibits human-based behavior in communication. 3 See Chapter 1 for the definition of a Human-Centered Visualization Environment

Scalability Considerations for Multivariate Graph Visualization

“…These can be limitations on the display technology, the graph data store, or on the means of computation on the graph. In this work, we focus on how graphics processors can enable scalable graph visualization and their limitations; for discussion on the limits and capabilities of displays and graph storage, we refer the reader to the relevant literature [2,21].…”

Toward the role of interaction in Visual Analytics

“…Such topics would widely go beyond the scope of this paper. The interested reader is referred to the literature, such as the book chapter (Fikkert et al 2007). …”

Combining 3-D geovisualization with force feedback driven user interaction

“…The research presented here relates to geographic visualization [18], especially the 3-D visualization of geospatial data [29,4,9] and to geoscientific virtual environments [6], to humancentered visualization techniques [5,3], to usability issues [25] and to 3-D user interface design [2].…”
