If visualization is to be democratized, we need provide means for non-experts create visualizations that allow them engage directly with datasets. We present constructive a new paradigm the simple creation of flexible, dynamic visualizations. Constructive simple-in skills required build and manipulate are akin kindergarten play; it expressive in one can within constraints chosen environment, also supports dynamics -- these constructed rebuilt adjusted. de- scribe conceptual components...
The accessibility of infovis authoring tools to a wide audience has been identified as major research challenge. A key task in the process is development visual mappings. While community long deeply interested finding effective mappings, comparatively little attention placed on how people construct In this paper, we present results study designed shed light transform data into representations. We asked create, update and explain their own information visualizations using only tangible...
Self-reflection is a central goal of personal informatics systems, and constructing visualizations from physical tokens has been found to help people reflect on data. However, so far, constructive physicalization only studied in lab environments with provided datasets. Our qualitative study investigates the construction physicalizations people's domestic over 2-4 weeks. It contributes an understanding (1) process creating physicalizations, (2) types insights facilitated, (3) integration...
"Virtual-Physical Perceptual Manipulations" (VPPMs) such as redirected walking and haptics expand the user's capacity to interact with Virtual Reality (VR) beyond what would ordinarily physically be possible. VPPMs leverage knowledge of limits human perception effect changes in physical movements, becoming able (perceptibly imperceptibly) nudge their actions enhance interactivity VR. We explore risks posed by malicious use VPPMs. First, we define, conceptualize demonstrate existence Next,...
Designing a data physicalization requires myriad of different considerations. Despite the cross-disciplinary nature these considerations, research currently lacks synthesis across communities sits upon, including their approaches, theories, and even terminologies. To bridge synergistically, we present design space that describes analyzes physicalizations according to three facets: context (end-user considerations), structure (the physical artifact), interactions (interactions with both...
In this paper we discuss the creation of visual mementos as a new application area for visualization. We define visualizations personally relevant data purpose reminiscing, and sharing life experiences. Today more people collect digital information about their than ever before. The shift from physical to archives poses challenges opportunities self-reflection self-representation. Drawing on research autobiographical memory role artifacts in identified design mementos: mapping evoke...
Uncertainty plays an important and complex role in data analysis, where the goal is to find pertinent patterns, build robust models, support decision making. While these endeavours are often associated with professional scientists, many domain experts engage such activities varying skill levels. To understand how (or "data workers") analyse uncertain we conducted a qualitative user study 12 participants from variety of domains. In this paper, describe their various coping strategies...
Human memory has notable limitations (e.g., forgetting) which have necessitated a variety of aids calendars). As we grow closer to mass adoption everyday Extended Reality (XR), is frequently leveraging perceptual redirected walking), it becomes pertinent consider how XR could leverage (forgetting, distorting, persistence) induce manipulations. memories highly impact our self-perception, social interactions, and behaviors, there pressing need understand Memory Manipulations (XRMMs). We ran...
This paper is a call to action for research and discussion on data visualization education. As evolves spreads through our professional personal lives, we need understand how support empower broad diverse community of learners in visualization. Data Visualization dynamic discipline that combines knowledge from different fields, tailored suit audiences contexts, frequently incorporates tacit knowledge. complex nature leads series interrelated challenges Driven by lack consolidated knowledge,...
We introduce Visual Sedimentation, a novel design metaphor for visualizing data streams directly inspired by the physical process of sedimentation. Visualizing (e. g., Tweets, RSS, Emails) is challenging as incoming arrive at unpredictable rates and have to remain readable. For streams, clearly expressing chronological order while avoiding clutter, keeping aging visible, are important. The drawn from real-world sedimentation processes: objects fall due gravity, aggregate into strata over...
In this pictorial, we present a method to facilitate hands-on physicalization processes during workshops. Data -- encoding data in physical artefacts allows for new ways represent and communicate and, as process, can make the principles of representation more "graspable". order (1) engage different research communities discuss from social technology point view, (2) promote data-driven prototyping, (3) teach creative process educational settings have run workshops within Human Computer...
While previous work exists on how to conduct and disseminate insights from problem-driven visualization projects design studies, the literature does not address accomplish these goals in transdisciplinary teams ways that advance all disciplines involved. In this paper we introduce define a new methodological paradigm call by immersion, which provides an alternative perspective work. Design immersion embeds experiences at center of process having researchers participate target domain (or...
Physical representations of data offer physical and spatial ways looking at, navigating, interacting with data. While digital fabrication has facilitated the creation objects data-driven geometry, rendering as a physically fabricated object is still daunting leap for many physicalization designers. Rendering in scope this research refers to back-and-forth process from design its specific challenges. We developed corpus example physicalizations literature practice. This survey then unpacks...
Whole-body movements enhance the presence and enjoyment of Virtual Reality (VR) experiences. However, using large gestures is often uncomfortable impossible in confined spaces (e.g., public transport). We introduce FingerMapper, mapping small-scale finger motions onto virtual arms hands to enable whole-body VR. In a first target selection study (n=13) comparing FingerMapper hand tracking ray-casting, we found that can significantly reduce physical fatigue while having similar degree...
Living bio-materials are increasingly used in HCI for fabricating objects by growing. However, how to integrate electronics make these interactive still needs be clarified. This paper presents an exploration of the fabrication design space Biohybrid Interactive Devices, a class devices fabricated merging electronic components and living organisms. From this using bacterial cellulose, we outline framework centered on biomaterials' life cycle phases. We introduce set novel techniques embedding...
Abstract Providing tools that make visualization authoring accessible to non‐experts is a major research challenge. Currently the most common approach generating use software quickly and automatically produces visualizations based on templates. However, it has recently been suggested constructing with tangible tiles may be more method, especially for people without expertise. There still much learned about differences between these two practices. To better understand how author in...
We investigate whether the notion of active reading for text might be usefully applied to visualizations. Through a qualitative study we explored people apply observable techniques when paper-based node-link Participants used range physical actions while reading, and from these synthesized an initial set To learn more about potential impact such may have on visualization implemented support one type action our observations (making freeform marks) in interactive visualization. Results...
Against the backdrop of a climate crisis, HCI researchers and designers are reflecting upon, reconsidering, re-imagining work that we do through lens sustainability. In this Studio, propose to adopt critical perspective Sustainable an examination reflection on environmental impact research conferences. Our Studio builds upon our prior explored sustainable methods toolkits for facilitating data physicalization workshops. We apply tools strategies developed within in which participants...
We examine input visualizations, visual representations that are designed to collect (and represent) new data rather than encode preexisting datasets. Information visualization is commonly used reveal insights and stories within existing data. As a result, most contemporary approaches assume datasets as the starting point for design, through which mapped encodings. Meanwhile, implications of visualizations inputs sources have received little attention—despite existence physical examples...
We investigate direct manipulation of graphical encodings as a method for interacting with visualizations. There is an increasing interest in developing visualization tools that enable users to perform operations by directly manipulating rather than external widgets such checkboxes and sliders. Designers must decide which should be supported, identify how each operation can invoked. However, we lack empirical guidelines people convey their intended using encodings. address this issue...
In recent years, Mixed Reality (MR) headsets have increasingly made advances in terms of capability, affordability and end-user adoption, slowly becoming everyday technology. HCI research typically explores positive aspects these technologies, focusing on interaction, presence immersive experiences. However, such technological paradigm shifts often fail to consider the "dark patterns", with potential abusive scenarios, possible by new technologies (cf. smartphone addiction, social media...
