Gestures in the wild: studying multi-touch gesture sequences on interactive tabletop exhibits

Uta Hinrichs; M. Sheelagh T. Carpendale

In this paper we describe our findings from a field study that was conducted at the Vancouver Aquarium to investigate how visitors interact with a large interactive table exhibit using multi-touch gestures. Our findings show that the choice and use of multi-touch gestures are influenced not only by general preferences for certain gestures but also by the interaction context and social context they occur in. We found that gestures are not executed in isolation but linked into sequences where previous gestures influence the formation of subsequent gestures. Furthermore, gestures were used beyond the manipulation of media items to support social encounters around the tabletop exhibit. Our findings indicate the importance of versatile many-to-one mappings between gestures and their actions that, other than one-to-one mappings, can support fluid transitions between gestures as part of sequences and facilitate social information exploration.

The bohemian bookshelf: supporting serendipitous book discoveries through information visualization

Alice Thudt; Uta Hinrichs; Sheelagh Carpendale

Serendipity, a trigger of exciting yet unexpected discoveries, is an important but comparatively neglected factor in information seeking, research, and ideation. We suggest that serendipity can be facilitated through visualization. To explore this, we introduce the Bohemian Bookshelf, which aims to support serendipitous discoveries in the context of digital book collections. The Bohemian Bookshelf consists of five interlinked visualizations each offering a unique overview of the collection. It aims at encouraging serendipity by (1) offering multiple visual access points to the collection, (2) highlighting adjacencies between books, (3) providing flexible visual pathways for exploring the collection, (4) enticing curiosity through abstract, metaphorical, and visually distinct representations of books, and (5) enabling a playful approach to information exploration. A deployment at a library revealed that visitors embraced this approach of utilizing visualization to support open-ended explorations and serendipitous discoveries. This encourages future explorations into promoting serendipity through information visualization.

EMDialog: Bringing Information Visualization into the Museum

Uta Hinrichs; Holly Schmidt; M. Sheelagh T. Carpendale

Digital information displays are becoming more common in public spaces such as museums, galleries, and libraries. However, the public nature of these locations requires special considerations concerning the design of information visualization in terms of visual representations and interaction techniques. We discuss the potential for, and challenges of, information visualization in the museum context based on our practical experience with EMDialog, an interactive information presentation that was part of the Emily Carr exhibition at the Glenbow Museum in Calgary. EMDialog visualizes the diverse and multi-faceted discourse about this Canadian artist with the goal to both inform and provoke discussion. It provides a visual exploration environment that offers interplay between two integrated visualizations, one for information access along temporal, and the other along contextual dimensions. We describe the results of an observational study we conducted at the museum that revealed the different ways visitors approached and interacted with EMDialog, as well as how they perceived this form of information presentation in the museum context. Our results include the need to present information in a manner sufficiently attractive to draw attention and the importance of rewarding passive observation as well as both short- and longer term information exploration.

Examination of Text-Entry Methods for Tabletop Displays

Uta Hinrichs; Mark S. Hancock; Christopher Collins; Sheelagh Carpendale

Although text entry is a vital part of day-to-day computing familiar to most people, not much research has been done to enable text entry on large interactive tables. One might assume that a good approach would be to choose an existing technique known to be fast, ergonomic, and currently preferred by the general population, but there are many additional factors to consider in this specific domain. We consider a variety of existing text-entry methods and examine their viability for use on tabletop displays. We discuss these techniques not only in terms of their general characteristics, performance, and adoption, but introduce other evaluative criteria, including: environmental factors unique to large digital tables and the support for multi-user simultaneous interaction. Based on our analysis we illustrate by example how to choose appropriate text-entry methods for tabletop applications with differing requirements, whether by selection from existing methods, or through a combination of desirable elements from a variety of methods. Our criteria can also be used as heuristics during the iterative design of a completely new text-entry technique.

Evaluating the effects of fluid interface components on tabletop collaboration

Uta Hinrichs; M. Sheelagh T. Carpendale; Stacey D. Scott

Tabletop displays provide exciting opportunities to support individual and collaborative activities such as planning, organizing, and storyboarding. It has been previously suggested that continuous flow of interface items can ease information access and exploration on a tabletop workspace, yet this concept has not been adequately studied. This paper presents an exploratory user study of Interface Currents, a reconfigurable and mobile tabletop interface component that offers a controllable flow for interface items placed on its surface. Our study shows that Interface Currents supported information access and sharing on a tabletop workspace. The study findings also demonstrate that mobility, flexibility, and general adjustability of Interface Currents are important factors in providing interface support for variations in task and group interactions.

SpiderEyes: designing attention- and proximity-aware collaborative interfaces for wall-sized displays

Jakub Dostal; Uta Hinrichs; Per Ola Kristensson; Aaron J. Quigley

With the proliferation of large multi-faceted datasets, a critical question is how to design collaborative environments, in which this data can be analysed in an efficient and insightful manner. Exploiting peoples movements and distance to the data display and to collaborators, proxemic interactions can potentially support such scenarios in a fluid and seamless way, supporting both tightly coupled collaboration as well as parallel explorations. In this paper we introduce the concept of collaborative proxemics: enabling groups of people to collaboratively use attention- and proximity-aware applications. To help designers create such applications we have developed SpiderEyes: a system and toolkit for designing attention- and proximity-aware collaborative interfaces for wall-sized displays. SpiderEyes is based on low-cost technology and allows accurate markerless attention-aware tracking of multiple people interacting in front of a display in real-time. We discuss how this toolkit can be applied to design attention- and proximity-aware collaborative scenarios around large wall-sized displays, and how the information visualisation pipeline can be extended to incorporate proxemic interactions.

FatFonts: combining the symbolic and visual aspects of numbers

Miguel A. Nacenta; Uta Hinrichs; Sheelagh Carpendale

In this paper we explore numeric typeface design for visualization purposes. We introduce FatFonts, a technique for visualizing quantitative data that bridges the gap between numeric and visual representations. FatFonts are based on Arabic numerals but, unlike regular numeric typefaces, the amount of ink (dark pixels) used for each digit is proportional to its quantitative value. This enables accurate reading of the numerical data while preserving an overall visual context. We discuss the challenges of this approach that we identified through our design process and propose a set of design goals that include legibility, familiarity, readability, spatial precision, dynamic range, and resolution. We contribute four FatFont typefaces that are derived from our exploration of the design space that these goals introduce. Finally, we discuss three example scenarios that show how FatFonts can be used for visualization purposes as valuable representation alternatives.

Interactive Public Displays

Uta Hinrichs; Sheelagh Carpendale; Nina Valkanova; Kai Kuikkaniemi; Giulio Jacucci; Andrew Vande Moere

Public-display installations can range from large-scale media facades that are embedded in architectural structures and that people can interact with only from a distance, to direct-touch interactive kiosks that provide information of local interest. These different scenarios impose different challenges and research questions regarding the design of interfaces and interaction techniques. The articles in this special issue present snapshots of several ways that researchers are addressing these challenges.

Digital Tables for Collaborative Information Exploration

Petra Isenberg; Uta Hinrichs; Mark S. Hancock; Sheelagh Carpendale

There is great potential for digital tabletop displays to be integrated in tomorrow’s work and learning environments, in which the exploration of information is a common task. In this chapter, we describe the stream of research that focuses on digital tabletop collaborative visualization environments. We focus on two types of interfaces: those for information exploration and data analysis in the context of workplaces, and those for more casual information exploration in public settings such as museums.

Interface currents: supporting fluent collaboration on tabletop displays

Uta Hinrichs; M. Sheelagh T. Carpendale; Stacey D. Scott; Eric Pattison

Large horizontal displays provide new opportunities to support individual and collaborative activities such as creativity and organizational tasks. We present Interface Currents, a fluid interaction technique designed to support face-to-face collaboration by improving access to and sharing of workspace items. Interface Currents are flexible containers that provide a controllable flow of interface items that support creativity during collaborative tasks and enable intuitive organization and sharing of digital information around horizontal displays.
