We introduce ImAxes immersive system for exploring multivariate data using fluid, modeless interaction. The basic interface element is an embodied axis. user can manipulate these axes like physical objects in the environment and combine them into sophisticated visualisations. type of visualisation that appears depends on proximity relative orientation with respect to one another, which we describe a formal grammar. This straight-forward composability leads number emergent visualisations...
Immersive Analytics is an emerging research thrust investigating how new interaction and display technologies can be used to support analytical reasoning decision making. The aim provide multi-sensory interfaces that collaboration allow users immerse themselves in their data a way supports real-world analytics tasks. builds on such as large touch surfaces, immersive virtual augmented reality environments, sensor devices other, rapidly evolving, natural user interface devices. While there...
High-quality immersive display technologies are becoming mainstream with the release of head-mounted displays (HMDs) such as Oculus Rift. These devices potentially represent an affordable alternative to more traditional, centralised CAVE-style environments. One driver for development environments has been collaborative sense-making. Despite this, there little research on effectiveness visualisation in facilities, especially respect abstract data tasks. Indeed, very few studies have focused...
Tactile maps are widely used in Orientation and Mobility (O&M) training for people with blindness severe vision impairment. Commodity 3D printers now offer an alternative way to present accessible graphics, however it is unclear if models advantages over tactile equivalents 2D graphics such as maps. In a controlled study 16 touch readers, we found that were preferred, enabled the use of more easily understood icons, facilitated better short term recall allowed relative height map elements be...
We introduce IATK, the Immersive Analytics Toolkit, a software package for Unity that allows interactive authoring and exploration of data visualisation in immersive environments. The design IATK was informed by interdisciplinary expert-collaborations as well visual analytics applications iterative refinement over several years. easy assembly visualisations through grammar graphics user can configure GUI-in addition to dedicated API supports creation novel designs interactions. is designed...
Immersive virtual- and augmented-reality headsets can overlay a flat image against any surface or hang virtual objects in the space around user. The technology is rapidly improving may, long term, replace traditional panel displays many situations. When are no longer intrinsically flat, how should we use user for abstract data visualisation? In this paper, ask question with respect to origin-destination flow global geographic context. We report on findings of three studies exploring...
Immersive analytics turns the very space surrounding user into a canvas for data analysis, supporting human cognitive abilities in myriad ways. We present results of design study, contextual inquiry, and longitudinal evaluation involving professional economists using Virtual Reality (VR) system multidimensional visualization to explore actual economic data. Results from our preregistered highlight varied use depending on context (exploration vs. presentation), organization support work,...
The visualization research community can and should reach broader audiences beyond data-savvy groups of people, because these could also greatly benefit from visual access to data. In this article, we discuss four topics-personal data visualization, on mobile devices, inclusive multimodal interaction for visualization-that, individually collaboratively, would help us with making more accessible.

Constraint multiset grammars provide a general, high-level framework for the definition of visual languages. They are new formalism based on rewriting. We give formal semantics constraint grammars, investigate theoretical complexity parsing with these and an incremental algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
We review the literature on automatic document formatting with an emphasis recent work in field. One common way to frame is as a constrained optimization problem where decision variables encode element placement, constraints enforce required geometric relationships, and objective function measures layout quality. present existing research using this framework, describing kind of being solved basic techniques used solve it. Our focuses primarily textual documents, including both micro-...
Showing flows of people and resources between multiple geographic locations is a challenging visualisation problem. We conducted two quantitative user studies to evaluate different visual representations for such dense many-to-many flows. In our first study we compared bundled node-link flow map representation OD Maps [37] with new call MapTrix. Like Maps, MapTrix overcomes the clutter associated traditional while providing embedding that missing in standard matrix representations. found had...
Over the last 50 years a wide variety of automatic network layout algorithms have been developed. Some are fast heuristic techniques suitable for networks with hundreds thousands nodes while others multi-stage frameworks higher-quality smaller networks. However, despite decades research currently no algorithm produces comparable quality to that human. We give new "human-centred" methodology design is intended overcome this deficiency. User studies first used identify aesthetic criteria...
In this paper, we investigate Confluent Drawings (CD), a technique for bundling edges in node-link diagrams based on network connectivity. Edge-bundling techniques are designed to reduce edge clutter by coalescing lines into common paths or bundles. Unfortunately, traditional introduce ambiguity since only bundled spatial proximity, rather than connectivity; following an from its source target can lead the perception of incorrect connectivity if not clearly separated within Contrary, CDs...
