Immersive technologies offer new opportunities to support collaborative visual data analysis by providing each collaborator a personal, high-resolution view of flexible shared visualisation space through head mounted display. However, most prior studies immersive analytics have focused on how groups interact with surface interfaces such as tabletops and wall displays. This paper reports study in which teams three co-located participants are given authoring tools allow great deal control they...

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...

Visual exploration of maps often requires a contextual understanding at multiple scales and locations. Multiview map layouts, which present hierarchy views to reveal detail various locations, have been shown support better performance than traditional single-view on desktop displays. This paper investigates the extension such layouts 2D into 3D immersive spaces, are not limited by real-estate barrier physical screens sensemaking through spatial interaction. Based our initial implementation...

The Equal Earth map projection is a new equal-area pseudocylindrical for world maps. It inspired by the widely used Robinson projection, but unlike retains relative size of areas. equations are simple to implement and fast evaluate. Continental outlines shown in visually pleasing balanced way.

We introduce Tilt Map, a novel interaction technique for intuitively transitioning between 2D and 3D map visualisations in immersive environments. Our focus is visualising data associated with areal features on maps, example, population density by state. Map transitions from choropleth maps to prism bar charts overcome the limitations of each. article includes two user studies. The first study compares subjects' task performance interpreting using virtual reality (VR). observed greater...

Worlds-in-Miniature (WiMs) are interactive worlds within a world and combine the advantages of an input space, cartographic map, overview+detail interface. They have been used across extended virtuality spectrum for variety applications. Building on analysis examples WiMs from research literature we contribute design space based seven dimensions. Further, expand upon existing definitions to provide definition that applies reality spectrum. We identify dimensions size-scope-scale,...

As mixed-reality (MR) technologies become more mainstream, the delineation between data visualisations displayed on screens or other surfaces and those floating in space becomes increasingly blurred. Rather than choice of using either a 2D surface 3D for visualising being dichotomy, we argue that users should have freedom to transform seamlessly two as needed. However, design such transformations is large, practically uncharted. To explore this, first establish an overview different states...

Freehand gesture interaction has long been proposed as a `natural' input method for Augmented Reality (AR) applications, yet little explored intensive applications like multiscale navigation. In navigation, such digital map pan and zoom are the predominant interactions. A position-based mapping (e.g. grabbing metaphor) is intuitive interactions, but prone to arm fatigue. This work focuses on improving navigation in AR with mid-air hand gestures, using horizontal intangible display. First, we...

This paper introduces a force-directed layout method for creating origin-destination flow maps. Design principles derived from manual cartography and automated graph drawing to increase readability of maps layouts are taken into account. The produced with our algorithm show flows quadratic Bézier curves that reduce flow-on-flow flow-on-node overlaps, avoid sharp or irregular bends in lines. A survey expert cartographers found created similar quality manually

All major web mapping services use the Mercator projection. This is a poor choice for maps of entire globe or areas size continents larger countries because projection shows medium and higher latitudes with extreme areal distortion provides an erroneous impression distances relative areas. The also not able to show globe, as polar cannot be mapped. When selecting alternative information visualization, rivaling factors have taken into account, such map scale, geographic area shown, map's...

Many small-scale map projections exist, and they have different shapes distortion characteristics. World are mainly chosen based on their properties the personal preferences of cartographers. Very little is known about projection map-readers; only two studies addressed this question so far.
