With their increasingly widespread use, mobile devices have become a highly relevant target environment for Information Visualization. However, far too little attention has been paid to evaluation of interactive visualization techniques on mobile devices. To fill this gap, this paper provides a structured overview of the commonly used evaluation ap...

Mobile devices are more and more used in parallel, esp. in the field of TV viewing as second screen devices. Such scenarios aim to enhance the viewers' user experience while watching TV. We designed and implemented a second screen prototype intended to be used in parallel to watching a TV documentary. It allows to interactively explore a combinatio...

Today many different devices and operating systems can be used for InfoVis systems. On the one hand, web-based visualizations can be used to be compatible with several systems, but the performance depends on optimized browser engines. On the other hand, it is possible to build a native system which supports all the benefits for just one device. How...

Many museums offer mobile apps to extend the brief descriptions of physical exhibits. However, these apps often reproduce on-site content, are not location-aware, or demand several user interactions to view the content. Therefore, we propose using visitors’ mobile devices to extend static information with time-oriented, situated information visuali...

In recent years, digital media have increasingly found their way into museums and its surroundings. Today, museums digitize their cultural heritage artifacts, create virtual museums that mainly exist online, or offer a digital extension to expand their audience and complement the physical exhibition. On the one hand, interactive installations are i...

Museums and libraries store a huge number of data related to their exhibition objects. Often, these data cannot be presented in exhibitions because of limited space or limited time during guided tours. Interweaving these physical artifacts with data visualization on digital media can help to make these data visible and searchable for visitors indep...

While second screen scenarios – that is, simultaneously using a phone, tablet or laptop while watching TV or a recorded broadcast - are finding their ways into the homes of millions of people, our understanding of how to properly design them is still very limited. We envision this design space and investigate how interactive data visualization can...

Not least because of ”Pokemon Go”, everyone is talking about context-sensitive applications. These applications are also widely used in tourism and in cultural institutions, whose collections can not be shown to the public physically due to renovation or because of a lack of a permanent exhibition house. We use these experiences in the application...

Almost every visitor brings their own mobile device (e.g., smartphone or tablet) to the museum. Although, many museums include interactive exhibits (e.g., multi-touch tables), the visitors’ own devices are rarely used as part of a device ecology. Currently, there is no suitable infrastructure to seamlessly link different devices in museums. Our app...

Opinion polls are omnipresent in broadcasting concepts and play an important role in live TV settings. However, involving the audience more intensively in both, the studio as well as at home in front of the television sets, and bringing them together using real-time interaction is still an open challenge. To tackle this aspect, we present LiveVis –...

Publications play a central role in presenting the outcome of scientific research but are typically presented as textual lists, whereas related work in visualization of publication focuses on exploration – not presentation. To bridge this gap, we conducted a design study of an interactive visual representation of publication data in a BibTeX file....

Mit der zunehmenden Nutzung von Wearables, welche die AnwenderInnen im täglichen Leben unter-stützen sollen, wird es immer wichtiger, für die jeweilige Applikation passende und informative Daten, aufgrund der dezimierten Darstellungs-und Interaktionsfläche, aber auch betriebssystemspezifischer Möglichkeiten, zu liefern. Besonders in der Information...

Modern data visualizations are developed as interactive and intuitive graphic applications. In the development process, programmers basically pursue the same goal: creating an application with a great performance. Such applications have to display information at its best way in every possible situation. In this paper, we present a performance compa...

The state of technology is evolving each year, computers get faster and smaller and more and more parts of society get enhanced with it. Education is one of these areas that could benefit from the progress made in technology. This paper explores the possibilities and benefits of mobile location-based learning games and tools for creating such appli...

Zusammenfassung/Abstract Durch den Einsatz von M-Learning können Studierende zeit-und ortsunabhängig Lernmaterial verwenden und ihren Bedürfnissen entsprechend beziehen. In dieser Arbeit wird der Einfluss von Anforderungen einer M-Learning-Applikation auf die Benutzerfreundlichkeit sowie auf die Haltung gegenüber von E-Learning-Systemen behandelt....

Multi-­Screen Anwendungen nutzen den Bildschirm mehrerer mobiler Geräte und können so einen Mehr-­ wert generieren. Für den Spielbereich ist hier vor allem das Shared-­Screen Muster von Interesse. Bei der Implementation dieses Musters stellt u.a. das Anleiten der BenutzerInnen zum richtigen Zusammenlegen der Geräte eine Herausforderung dar. Diese A...

Traditional medial content was consumed with one device at a time. With the increasing simultaneous usage of several different devices like smart-phone, tablet and connected TV new approaches for media consumption are conceivable. One specific instance is a Second Screen scenario where users complement information from unidirectional media broadcas...

The research of this paper deals with digital shop windows and their clients interacting with it. The glass pane between user and system prevents direct contact with the screen and thus forces the user to actively interact via gesture control with the system. With help of a self-developed prototype of a gesture driven digital shop window control sy...

The Web evolves very fast, day by day. With current technologies, it is possible to create web applications with a look and feel that comes close to those of native apps. The same applies to the implementation of touch gestures in mobile web browsers, even if that possibility is not as often used as in native smartphone applications. This paper dea...

Unsere Step-basierte Indoor-Navigation für Smartphones ist eine Navigationslösung basierend auf Web-Technologien, die zur Positionierung mit künstlichen, visuellen Landmarks (QR-Codes) arbeitet. Die zu-rückzulegende Strecke wird dabei in überschaubare Abschnitte (Steps) unterteilt. Usabilty Tests zeigen, dass diese Art der Navigation von den Nutzer...

In diesem Paper wird das Konzept und ein Prototyp eines Step-by-Step basierten Inhouse-Navigationssystems vorgestellt, wel- ches aus technischen und finanziellen Gründen auf eine kontinuierliche Positionserkennung verzichtet und mit vergleichsweise geringem Aufwand an neuen Orten eingeführt werden kann. Im Vorfeld wurden in einer intensiven Recherc...

In Austria in 2011, 37% of all Austrians used the Internet via mobile devices (WUNDERMANN PXP GmbH, 2011) – the highest percentage so far. These numbers show that there is a great potential for applications for mobile devices. Smartphones are used at all times an...

Zusammenfassung Wird eine Applikation auf einem Smartphone nebenher benutzt, so muss der User seine kognitiven Ressourcen auf das Benutzen der Applikation und das Ausführen einer primären Tätigkeit aufteilen. Labor-basierende klassische Usability-Tests berücksichti-gen nicht den Einfluss des Primärtasks. In Feldstudien können jedoch die den Test be...

During the use of mobile applications on the move the user's cognitive resources are split into handling the application and conducting a primary task, i.e. walking or driving a car. Traditional lab-based usability tests do not take the influence of fragmented attention into account. In field tests on the other hand we cannot control environmental...
