Summary: We focus on the use of interactive surfaces for visual data exploration. The workshop topics are situated at the intersection of Interaction and Visualization research, and we ask for contributions from members of one or both communities. Our main goal is to call for the development of more dedicated research on visualization systems for interactive surfaces ranging from small screen smartphones to medium-size tables to large wall-size displays. The workshop is meant to provide a space for visualization and interaction researchers to meet, discuss, advance the state-of-the-art, and refine research agendas.

Summary: Physical representations of data have existed for thousands of years. Yet it is now that advances in digital fabrication, actuated tangible interfaces, and shape-changing displays are spurring an emerging area of research that we call Data Physicalization. It aims to help people explore, understand, and communicate data using computer-supported physical data representations. We call these representations physicalizations, analogously to visualizations -- their purely visual counterpart. In this article, we go beyond the focused research questions addressed so far by delineating the research area, synthesizing its open challenges and laying out a research agenda.

ACM Digital Library Link

Summary: We studied how the integration of small visualizations (word-scale visualizations) into a sentence affects reading speed and memorization during a brief reading task. In particular, we were interested in how different placement types with their inherent text appearance and layout changes affect readers. We designed a quantitative study in which we gave sentences with or without visualizations for participants to read. Then, we invited them to answer questions on the sentences. We found that the information encoded in the visualizations is more prominent and easily remembered than information in the written text, but that different placement options had little to no effect on reading performance, even if participants had different preferences.

ACM Digital Library Link

Summary: We present the results of a controlled experiment to investigate the performance of different temporal glyph designs in a small multiple setting. Analyzing many time series at once is a common yet difficult task in many domains, for example in network monitoring. Several visualization techniques have, thus, been proposed in the literature. Among these, iconic displays or glyphs are an appropriate choice because of their expressiveness and effective use of screen space. Through a controlled experiment, we compare the performance of four glyphs that use different combinations of visual variables to encode two properties of temporal data: a) the position of a data point in time and b) the quantitative value of this data point. Our results show that depending on tasks and data density, the chosen glyphs performed differently. Line Glyphs are generally a good choice for peak and trend detection tasks but radial encodings are more effective for reading values at specific temporal locations. From our qualitative analysis we also contribute implications for designing temporal glyphs for small multiple settings.

Summary: We present PolemicTweet a system with an encompassing, economic, and engaging approach to video tagging and analysis. Annotating and tagging videos manually is a boring and time-consuming process. Yet, in the last couple of years the audiences of events -- such as academic conferences -- have begun to produce unexploited metadata in the form of micropost activities. With PolemicTweet we explore the use of tagged microposts for both video annotation and browsing aid. PolemicTweet is a system 1) to crowd source conference video tagging with structured sentiment metadata, 2) to engage audiences in a tagging process, and 3) to visualize these annotations for browsing and analyzing a video. We describe the system and its components as well as the results from a one-year live deployment in 27 different events.

ACM Digital Library Link

Summary: We introduce Stackables: tangibles designed to support faceted information seeking in a variety of contexts. We are faced, more than ever, with tasks that require us to find, access, and act on information by ourselves or together with others. Current interfaces for browsing and search in large data spaces, however, largely focus on the support of either individual or collaborative activities. Stackables were designed to bridge this gap and be useful in meetings, for sharing results from individual search activities, and for realistic datasets including multiple facets with large value ranges. Each Stackable tangible represents search parameters that can be shared amongst collaborators, modified during an information seeking process, and stored and transferred. We describe Stackables, their flexible and expressive combination to formulate queries, and the underlying interaction concept in detail. An evaluation provides initial evidence of their usability in targeted and exploratory information seeking tasks.

ACM Digital Library Link

Summary: We demonstrate Stackables, tangible widgets designed for individual and collaborative faceted browsing. In contrast, current interfaces for browsing and search in large data spaces largely focus on supporting either individual or collaborative activities. Each stackable facet token represents search parameters that can be shared amongst collaborators, modified, and stored. We show how individuals or multiple people can interact with Stackables and combine them to formulate queries on realistic datasets. We have successfully used and evaluated Stackables in a user study with a dataset of over 1500 books and 12 facets with ranges of thousands of facet values.

ACM Digital Library Link

Summary: We present Cardiogram, a visual analytics system that supports automotive engineers in debugging masses of traces each consisting of millions of recorded messages from in-car communication networks. With their increasing complexity, ensuring these safety-critical networks to be error-free has become a major task and challenge for automotive engineers. To overcome shortcomings of current analysis tools, Cardiogram combines visualization techniques with a data preprocessing approach to automatically reduce complexity based on engineers' domain knowledge. In this paper, we provide the findings from an exploratory, three-year field study within a large automotive company, studying current practices of engineers, the challenges they meet and the characteristics for integrating novel visual analytics tools into their work practices.
We then introduce Cardiogram, discuss how our field analysis influenced our design decisions, and present a qualitative, long-term, in-depth evaluation. Results of this study showed that our participants successfully used Cardiogram to increase the amount of analyzable information, to externalize domain knowledge, and to provide new insights into trace data. Our design approach finally led to the adoption of Cardiogram into engineers' daily practices.

ACM Digital Library Link

Summary: Cambiera is a tabletop system designed for co-located collaborative visual analytics. As a tabletop system, Cambiera encourages analysts to face each other around the tabletop to analyze large text document collections collaboratively. Cambiera allows analysts to search for documents and read them, organize documents on the tabletop, and to monitor each other's' work. The video illustrates the major collaborative features of Cambiera.

Keywords: collaboration, communication, easy-to-use, hard-to-use, usability, user experience, user interfaces

ACM Digital Library Link

Summary: Researchers in HCI share a common understanding that 'easy-to-use', 'easy-to-learn' and 'intuitive' interfaces are beneficial to users. Designing such interfaces raises challenges and often requires multiple iterations. While we are generally prompt to discard more hard-to-use interfaces and smooth out usability issues, we want to raise here the issue of their potential benefits. We de-scribe two cases in which we observed potential bene-fits from introducing barriers for collaborating and communicating with others. We attempt to shed a new light on interfaces with usability "problems" and how these problems may benefit system efficiency and user experience. We end with a discussion of the pros and cons of making systems harder for people to use, and how to integrate this perspective in the design process.

ACM Digital Library Link

Summary: We examine the process and some implications of evaluating information visualization in a large company setting. While several researchers have addressed the difficulties of evaluating information visualizations with regards to changing data, tasks, and visual encodings, considerably less work has been published on the difficulties of evaluation within specific work contexts. In this paper, we specifically focus on the challenges arising in the context of large companies with several thousand employees. We present a collection of evaluation challenges, discuss our own experiences conducting information visualization evaluation within the context of a large automotive company, and present a set of recommendations derived from our experiences. The set of challenges and recommendations can aid researchers and practitioners in preparing and conducting evaluations of their products within a large company setting.

Summary: Tabletop displays with touch-based input provide many powerful affordances for directly manipulating and collaborating around information visualizations. However, these devices also introduce several challenges for interaction designers, including discrepancies among the resolutions of the visualization, the tabletop's display, and its sensing technologies; a need to support diverse types of interactions required by different visualization techniques; and the ability to support face-to-face collaboration. As a result, most interactive tabletop applications for working with information currently demonstrate limited functionality and do not approach the power or versatility of their desktop counterparts.
We present a series of design considerations, informed by prior interaction design and focus+context visualization research, for ameliorating the challenges inherent in designing practical interaction techniques for tabletop information visualization applications. We then discuss two specific techniques, i-Loupe and iPodLoupe, which illustrate how different choices among these design considerations enable vastly different experiences in working with complex data on interactive surfaces.

Summary: Two-handed, multi-touch surface computing provides a scope for interactions that are closer analogues to physical interactions than classical windowed interfaces. The design of natural and intuitive gestures is a difficult problem as we do not know how users will approach a new multi-touch interface and which gestures they will attempt to use. In this paper we study whether familiarity with other environments influences how users approach interaction with a multi-touch surface computer as well as how efficiently those users complete a simple task. Inspired by the need for object manipulation in information visualization applications, we asked users to carry out an object sorting task on a physical table, on a tabletop display, and on a desktop computer with a mouse. To compare users' gestures we produced a vocabulary of manipulation techniques that users apply in the physical world and we compare this vocabulary to the set of gestures that users attempted on the surface without training. We find that users who start with the physical model finish the task faster when they move over to using the surface than users who start with the mouse.

ACM Digital Library Link

Summary: To design information visualization tools for collaborative use, we need to understand how teams engage with visualizations during their information analysis process. We report on an exploratory study of individuals, pairs, and triples engaged in information analysis tasks using paper-based visualizations. From our study results, we derive a framework that captures the analysis activities of co-located teams and individuals. Comparing this framework with existing models of the information analysis process suggests that information visualization tools may benefit from providing a flexible temporal flow of analysis actions.

Summary: We introduce grounded evaluation as a process that attempts to ensure that the evaluation of an information visualization tool is situated within the context of its intended use. We discuss the process and scope of grounded evaluation in general, and then describe how qualitative inquiry may be a beneficial approach as part of this process. We advocate for increased attention to the field of qualitative inquiry early in the information visualization development life cycle, as it tries to achieve a richer understanding by using a more holistic approach considering the interplay between factors that influence visualizations, their development, and their use. We present three case studies in which we successfully used observational techniques to inform our understanding of the visual analytics process in groups, medical diagnostic reasoning, and visualization use among computational linguists.
