Modern computer systems have been built around the assumption that persistent storage is accessed via a slow, block-based interface. However, new byte-addressable, memory technologies such as phase change (PCM) offer fast, fine-grained access to storage.
Animation has been used to show trends in multi-dimensional data. This technique recently gained new prominence for presentations, most notably with Gapminder Trendalyzer. In Trendalyzer, animation together interesting data and an engaging presenter helps the audience understand results of analysis It is less clear whether trend effective analysis. paper proposes two alternative visualizations that use static depictions trends: one which shows traces all overlaid simultaneously display a...

Technology companies have been leading the way to a renewable energy transformation, by investing in sources reduce carbon footprint of their datacenters. In addition helping build new solar and wind farms, make power purchase agreements or offsets, rather than relying on every hour day, day week (24/7). Relying 24/7 is challenging due intermittent nature energy. Inherent variations production causes excess lack supply at different times. To cope with fluctuations generation, multiple...
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...
Head-mounted augmented reality (AR) displays allow for the seamless integration of virtual visualisation with contextual tangible references, such as physical (tangible) globes. We explore design immersive geospatial data AR and investigate "tangible-virtual interplay" globes visualisation, propose a conceptual approach designing demonstrate set use cases, augmenting globe overlays, using input device interacting maps, linking an to abstract visualisation. gathered qualitative feedback from...
Situated visualization has become an increasingly popular research area in the community, fueled by advancements augmented reality (AR) technology and immersive analytics. Visualizing data spatial proximity to their physical referents affords new design opportunities considerations not present traditional visualization, which researchers are now beginning explore. However, AR community extensive history of designing graphics that displayed highly contexts. In this work, we leverage richness...
Abstract Many factors can shape the flow of visual data‐driven stories, and thereby way readers experience those stories. Through analysis 80 existing stories found on popular websites, we systematically investigate identify seven characteristics these which name “flow‐factors,” illustrate how they feed into broader concept “visual narrative flow.” These flow‐factors are navigation input, level control, progress, story layout, role visualization, progression, feedback. We also describe a...
Abstract Visualization researchers have been increasingly leveraging crowdsourcing approaches to overcome a number of limitations controlled laboratory experiments, including small participant sample sizes and narrow demographic backgrounds study participants. However, as community, we little understanding on when, where, how use for visualization research. In this paper, review the evaluation in We analyzed 190 reported 82 papers that were published major conferences journals between 2006...
A fundamental part of data visualization is transforming to map abstract information onto visual attributes. While this abstraction a powerful basis for visualization, the connection between representation and original underlying (i.e., what quantities measurements actually correspond with in reality) can be lost. On other hand, virtual reality (VR) being increasingly used represent real models as natural experiences users. In work, we explore potential using VR help restore basic...
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...
Abstract In this paper, we introduce Canis, a high‐level domain‐specific language that enables declarative specifications of data‐driven chart animations. By leveraging data‐enriched SVG charts, its grammar animations can be applied to the charts created by existing construction tools. With designers select marks from partition selected into mark units based on data attributes, and apply animation effects units, with control when start. The Canis compiler automatically synthesizes Lottie...
We present Deimos, a grammar for specifying dynamic embodied immersive visualisation morphs and transitions. A morph is collection of animated transitions that are dynamically applied to visualisations at runtime conceptually modelled as state machine. It comprised state, transition, signal specifications. States in used generate animation keyframes, with connecting two states together. transition controlled by signals, which composable data streams can be enable interaction techniques....
Tangible controls-especially sliders and rotary knobs-have been explored in a wide range of interactive applications for desktop immersive environments. Studies have shown that they support greater precision provide proprioceptive benefits, such as eyes-free interaction. However, controls tend to be expressly designed specific applications. We draw inspiration from bespoke controller data visualisation, but decompose this design into simple, wireless, composable unit featuring two actuated...
When collaborating face-to-face, people commonly use the surfaces and spaces around them to perform sensemaking tasks, such as spatially organising documents, notes or images. However, when collaborate remotely using desktop interfaces they no longer feel like are sharing same space. This limitation may be overcome through collaboration in immersive environments, which simulate physical in-person experience. In this paper, we report on a between-groups study comparing collaborations image...
Extended reality (XR) technologies are highly suited in assisting individuals learning motor skills and movements—referred to as motion guidance. In guidance, the "feedforward'' provides instructional cues of motions that be performed, whereas "feedback'' which help correct mistakes minimize errors. Designing synergistic feedforward feedback is vital providing an effective experience, but this interplay between two has not yet been adequately explored. Based on a survey literature, we...
Building a sustainable datacenter requires coordinated decisions in its design and system management. Existing research work on sustainability often considers the space isolation misses opportunities to minimize carbon footprint through management where is first-class objective. Design such as site selection, renewable energy investment portfolios, provisioning of storage are intertwined with complementary solutions for operation, including various forms demand response carbon-aware workload...
Brushing and linking is widely used for visual analytics in desktop environments. However, using this approach to link many data items between situated (e.g., a virtual screen with data) embedded views highlighted objects the physical environment) largely unexplored. To end, we study effectiveness of highlighting techniques helping users identify referents brushed marks scatterplot. In an exploratory reality user (N=20), evaluated four under different layouts tasks. We discuss these...

Amyotrophic lateral sclerosis (ALS) is linked to the reduction of certain nucleoporins in neurons. Increased nuclear localization charged multivesicular body protein 7 (CHMP7), a involved pore surveillance, has been identified as key factor damaging pores and disrupting transport. Using CRISPR-based microRaft, followed by gRNA identification (CRaft-ID), we discovered 55 RNA-binding proteins (RBPs) that influence CHMP7 localization, including SmD1, survival motor neuron (SMN) complex...
