Abstract：Using the theory of affordance from perceptual psychology and through discussion of literature within visual data mining and immersive analytics, a position for the multi-sensory representation of big data using virtual reality (VR) is developed. While it would seem counter intuitive, information-dense virtual environments are theoretically easier to process than simplified graphic encoding—if there is alignment with human ecological perception of natural environments. Potentially, VR affords insight into patterns and anomalies through dynamic experience of data representations within interactive, kinaesthetic audio-visual virtual environments. To this end we articulate principles that can inform the development of VR applications for immersive analytics: a mimetic approach to data mapping that aligns spatial, aural and kinaesthetic attributes with abstractions of natural environments; layered with constructed features that complement natural structures; the use of cross-modal sensory mapping; a focus on intermediate levels of contrast; and the adaptation of naturally occurring distribution patterns for the granularity and distribution of data. While it appears problematic to directly translate visual data mining techniques to VR, the ecological approach to human perception discussed in this article provides a new framework for big data visualization researchers to consider.

1 Introduction

Typically, visual analytics has been deployed when data problems are ill defined and/or the configuration of the data is not easily subject to algorithmic analysis. Within the context of big data these characteristics are the norm, leading to increased interest in applications known as visual data mining (VDM). The aim of VDM is to augment algorithmic analysis with human visual cognition, where data variables are mapped to graphic attributes and differentiated through spatial position, shape and colour, thus bringing human visual perception and creativity to analysis [1, 2]. VDM utilizes graphic mapping techniques ranging from graphs and scatterplots to tree maps, display icons, tag clouds and cluster grams. While there has being some activity and speculation on the potential of virtual reality (VR) for visual analytics, application has been hindered by limited access to suitable hardware [3, 4, 5]. The recent availability of low cost, high performing head mounted displays (HMD) and compatibility with feature rich application authoring platforms such as Unity, has facilitated increased interest in the potential of VR for visual analytics. This has led to the new sub-field of research termed immersive analytics, which explores the potential of immersion in VR to extend existing graphic mapping techniques [6].

The position we develop in this article contributes to the research agenda of immersive analytics through considering the affordanceof the technology, with the objective of developing key principles that can inform the specification of software prototypes for immersive analytics. The term affordance will be familiar to many readers through Hartson [7], who clarified the practical utility of the theory for the design of Human Computer Interfaces (HCI). The concept of affordance was originally developed in psychology by James J. Gibson, whose lsquo;Ecological Approach to Visual Perceptionrsquo; [8] was described at the time as a revolutionary shift away from cognitive theories of psychology [9]. As we will discuss, there are a range of ways in which affordance has been defined and used in different domains, but for the purposes of this introduction the broad definition below by Stuckey et al. developed in relation to the design of virtual environments, captures our intent. “hellip; we use the concept of affordance to refer to the latent possibilities for action presented by an artefact, tool or environment” [ 剩余内容已隐藏，支付完成后下载完整资料
