Effects of Different Display Form Factors on InfoVis Applications: Exploring Selection Management and Brushing and Linking for Mobile Cross-Device Interaction

Diese Arbeit untersucht wie man mit mehreren, miteinander koordinierten Mobilgeräten Selektionen verwalten und Brushing und Linking unterstützen kann. Im Rahmen der Arbeit wird ein konzeptionelles Framework zur Selektionsverwaltung für mehrere Geräte angedacht und ein Konzept zur Selektionsverwaltung vorstellt, das Brushing und Linking für Mobilgeräte unterstützt. Des Weiteren werden Ziele für den Prototypen erörtert, die zur Umsetzung das Konzept beitragen. Mobile Geräte werden immer häufiger für Informationsvisualisierungen verwendet. Jedoch wurde bisher noch nicht untersucht, wie gängige Interaktionstechniken, wie Brushing und Linking, für diese Geräte anpassen werden müssen. Während des Brushings, werden zusätzlich Selektionen erstellt, für die es bislang keine Art der Verwaltung für Mobilgeräte gibt. In dieser Arbeit wird untersucht wie man Brushing und Linking mit mehreren Mobilgeräten unterstützen kann und Selektionen gleichzeitig verwalten kann.:1 Introduction 1.1 Contributions 1.2 Motivation and Background 1.3 Goals 1.4 Research Questions 1.5 Thesis Overview 2.

We discuss thoughts for a conceptual framework for selection management in multi-device environments. We then present a concept for managing selections and supporting brushing and linking for co-located mobile devices. Finally, we are providing an overview of and the goals for our proof-of-concept prototype. More and more mobile devices are used for visualization. However, it is still an open question how to adjust common interaction techniques, such as brushing and linking, for mobile devices. Furthermore, it has not been addressed how to manage the selections that are created through brushing. We explore how brushing and linking can be used in a setting with multiple, co-located mobile devices and how to manage its selections.:1 Introduction 1.1 Contributions 1.2 Motivation and Background 1.3 Goals 1.4 Research Questions 1.5 Thesis Overview 2.

Wavelet Menus: A Stacking Metaphor for Adapting Marking Menus to Mobile Devices

4 pagesInternational audienceExploration and navigation in multimedia data hierarchies (e.g., photos, music) are frequent tasks on mobile devices. However, visualization and interaction are impoverished due to the limited size of the screen and the lack of precise input devices. As a result, menus on mobile devices do not provide efficient navigation as compared to many innovative menu techniques proposed for Desktop platforms. In this paper, we present Wavelet, the adaptation of the Wave menu for the navigation in multimedia data on iPhone. Its layout, based on an inverted representation of the hierarchy, is particularly well adapted to mobile devices. Indeed, it guarantees that submenus are always displayed on the screen and it supports efficient navigation by providing previsualization of the submenus

Outdoor Augmented Reality: State of the Art and Issues

International audienceThe goal of an outdoor augmented reality system is to allow the human operator to move freely without restraint in its environment, to view and interact in real time with geo-referenced data via mobile wireless devices. This requires proposing new techniques for 3D localization, visualization and 3D interaction, adapted to working conditions in outdoor environment (brightness variation, features of displays used, etc.). This paper surveys recent advances in outdoor augmented reality. It resumes a large retrospective of the work carried out in this field, especially on methodological aspects (localization methods, generation of 3D models, visualization and interaction approaches), technological aspects (sensors, visualization devices and architecture software) and industrial aspects

WEST: A Web Browser for Small Terminals

We describe WEST, a WEb browser for Small Terminals, that aims to solve some of the problems associated with accessing web pages on hand-held devices. Through a novel combination of text reduction and focus+context visualization, users can access web pages from a very limited display environment, since the system will provide an overview of the contents of a web page even when it is too large to be displayed in its entirety. To make maximum use of the limited resources available on a typical hand-held terminal, much of the most demanding work is done by a proxy server, allowing the terminal to concentrate on the task of providing responsive user interaction. The system makes use of some interaction concepts reminiscent of those defined in the Wireless Application Protocol (WAP), making it possible to utilize the techniques described here for WAP-compliant devices and services that may become available in the near future

Visualising Bluetooth interactions: combining the Arc Diagram and DocuBurst techniques

Within the Bluetooth mobile space, overwhelmingly large sets of interaction and encounter data can very quickly be accumulated. This presents a challenge to gaining an understanding and overview of the dataset as a whole. In order to overcome this problem, we have designed a visualisation which provides an informative overview of the dataset. The visualisation combines existing Arc Diagram and DocuBurst techniques into a radial space-filling layout capable of conveying a rich understanding of Bluetooth interaction data, and clearly represents social networks and relationships established among encountered devices. The end result enables a user to visually interpret the relative importance of individual devices encountered, the relationships established between them and the usage of Bluetooth 'friendly names' (or device labels) within the data

NEMESYS: Enhanced Network Security for Seamless Service Provisioning in the Smart Mobile Ecosystem

As a consequence of the growing popularity of smart mobile devices, mobile malware is clearly on the rise, with attackers targeting valuable user information and exploiting vulnerabilities of the mobile ecosystems. With the emergence of large-scale mobile botnets, smartphones can also be used to launch attacks on mobile networks. The NEMESYS project will develop novel security technologies for seamless service provisioning in the smart mobile ecosystem, and improve mobile network security through better understanding of the threat landscape. NEMESYS will gather and analyze information about the nature of cyber-attacks targeting mobile users and the mobile network so that appropriate counter-measures can be taken. We will develop a data collection infrastructure that incorporates virtualized mobile honeypots and a honeyclient, to gather, detect and provide early warning of mobile attacks and better understand the modus operandi of cyber-criminals that target mobile devices. By correlating the extracted information with the known patterns of attacks from wireline networks, we will reveal and identify trends in the way that cyber-criminals launch attacks against mobile devices.Comment: Accepted for publication in Proceedings of the 28th International Symposium on Computer and Information Sciences (ISCIS'13); 9 pages; 1 figur

Mixed-methods research: a new approach to evaluating the motivation and satisfaction of university students using advanced visual technologies

The final publication is available at link.springer.comA mixed-methods study evaluating the motivation and satisfaction of Architecture degree students using interactive visualization methods is presented in this paper. New technology implementations in the teaching field have been largely extended to all types of levels and educational frameworks. However, these innovations require approval validation and evaluation by the final users, the students. In this paper, the advantages and disadvantages of applying mixed evaluation technology are discussed in a case study of the use of interactive and collaborative tools for the visualization of 3D architectonical models. The main objective was to evaluate Architecture and Building Science students’ the motivation to use and satisfaction with this type of technology and to obtain adequate feedback that allows for the optimization of this type of experiment in future iterations.Postprint (author’s final draft
