Tap or swipe? Effects of interaction gestures for retrieval of match statistics via second screen on watching soccer on TV

Accessing match statistics through second screen while watching soccer matches on TV has grown into a popular practice. Although early works have shown how gestures on touch screens performed under distracting environments, little is known regarding how specific gestures (swiping and tapping) to retrieve information on second screen affect the viewing experience of soccer games on TV. For this, a mixed-method user study, which included prototype tests of watching short clips of a soccer match, questionnaires and short interviews, was conducted with 28 participants. The results revealed that the number of people who preferred tapping was more than the number of people who favored swiping under two different second screen activity time scenarios i.e. On-Play or Off-Play. However, neither swiping nor tapping yield better performance of recalling verbatim match stats and exact comparisons in both On-Play and Off-Play. Participant evaluations in On-Play and interviews give us clues regarding such difference.</p

These are the Proceedings of the 4th IUI Workshop on Interacting with Smart Objects. Objects that we use in our everyday life are expanding their restricted interaction capabilities and provide functionalities that go far beyond their original functionality. They feature computing capabilities and are thus able to capture information, process and store it and interact with their environments, turning them into smart objects

Understanding and supporting mobile application usage

In recent years mobile phones have evolved significantly. While the very first cellular phones only provided functionality for conducting phone calls, smartphones nowadays provide a rich variety of functionalities. Additional hardware capabilities like new sensors (e.g.~for location) and touch screens as new input devices gave rise to new use cases for mobile phones, such as navigation support, taking pictures or making payments. Mobile phones not only evolved with regard to technology, they also became ubiquitous and pervasive in people\u27s daily lives by becoming capable of supporting them in various tasks. Eventually, the advent of mobile application stores for the distribution of mobile software enabled the end-users themselves to functionally customize their mobile phones for their personal purposes and needs. So far, little is known about how people make use of the large variety of applications that are available. Thus, little support exists for end-users to make effective and efficient use of their smartphones given the huge numbers of applications that are available. This dissertation is motivated by the evolution of mobile phones from mere communication devices to multi-functional tool sets, and the challenges that have arisen as a result. The goal of this thesis is to contribute systems that support the use of mobile applications and to ground these systems\u27 designs in an understanding of user behavior gained through empirical observations. The contribution of this dissertation is twofold: First, this work aims to understand how people make use of, organize, discover and multitask between the various functionalities that are available for their smartphones. Findings are based on observations of user behavior by conducting studies in the wild. Second, this work aims to assist people in leveraging their smartphones and the functionality that is available in a more effective and efficient way. This results in tools and improved user interfaces for end-users. Given that the number of available applications for smartphones is rapidly increasing, it is crucial to understand how people make use of such applications to support smartphone use in everyday life with better designs for smartphone user interfaces.Mobiltelefone haben sich innerhalb der letzten Jahre signifikant weiterentwickelt. Während erste Modelle lediglich Sprachtelefonie zur Verfügung stellten, ermöglichen heutige Smartphones vielseitige Dienste. Technologische Fortschritte, wie beispielsweise GPS-Lokalisierung und berührungsempfindliche Displays, haben neue Einsatzbereiche für Mobiltelefone eröffnet, wie solche als Navigationsgerät oder als Fotoapparat. Doch nicht nur in Bezug auf die Technologie haben sich Mobiltelefone weiterentwickelt, sondern auch in der Verbreitung ist die Anzahl der Geräte enorm gestiegen. Sie werden allgegenwärtig im täglichen Leben genutzt, da sie ihre Anwender bei verschiedensten Aufgaben unterstützen können. Das Aufkommen von Vetriebsplattformen für die Verbreitung mobiler Software erlaubt es dem Anwender selbstständig Modifikationen an der Funktionalität seines Geräts vorzunehmen und dieses an persönliche Zwecke und Ansprüche anzupassen. Bisher ist wenig darüber bekannt, wie sich Anwender die Vielfalt zu Verfügung stehender Applikationen zu Nutze machen. Als Folge daraus gibt es bisher nur rudimentäre Unterstützung für Anwender, die Vielfalt von Applikationen effektiv und effizient einzusetzen. Diese Dissertation ist durch den Wandel des Mobiltelefons vom reinen Kommunikationsgerät hin zum multifunktionalen Werkzeug motiviert. Das Ziel dieser Arbeit ist es, Systeme für die Unterstützung einer besseren mobilen Applikationsnutzung zu entwickeln, deren Design auf dem neuen Verständnis von Benutzerverhalten beruht, das durch empirische Studien gewonnen wird. Diese Dissertation hat einen zweiteiligen Beitrag: Zum einen werden theoretische Erkenntnisse dazu erarbeitet, wie Anwender die Applikationsvielfalt nutzen, installierte Applikationen auf ihren Geräten organisieren, neue Applikationen entdecken und zwischen diesen in der Ausführung wechseln. Die Erkenntnisse hierzu beruhen auf der empirischen Beobachtung von Nutzungsverhalten. Zum anderen hat diese Arbeit ingenieurwissenschaftliche Ziele dahingehend, die Anwender von Applikationen dabei zu unterstützen, ihre Smartphones sowie deren Funktionsvielfalt effektiver und effizienter einzusetzen. Dieser Beitrag resultiert in der Beschreibung implementierter Systeme und verbesserter Benutzerschnittstellen für Anwender. Angesichts der rapide wachsenden Zahl zur Verfügung stehender mobiler Applikationen ist es wichtig, zu verstehen wie Endanwender diese nutzen, denn nur so kann die Nutzung von Smartphones gebrauchstauglicher und einfacher gestaltet werden

(M)ad to see me?: Intelligent Advertisement Placement: Balancing User Annoyance and Advertising Effectiveness

Advertising is an unavoidable albeit a frustrating part of mobile interactions. Due to limited form factor, mobile advertisements often resort to intrusive strategies where they temporarily block the user's view in an attempt to increase effectiveness and force the user's attention. While such strategies contribute to advertising awareness and effectiveness, they do so at the cost of degrading the user's overall experience and can lead to frustration and annoyance. In this paper, we contribute by developing Perceptive Ads as an intelligent advertisement placement strategy that minimizes disruptions caused by ads while preserving their effectiveness. Our work is the first to simultaneously consider the needs of users, app developers, and advertisers. Ensuring the needs of all stakeholders are taken into account is essential for the adoption of advertising strategies as users (and indirectly developers) would reject strategies that are disruptive but effective, while advertisers would reject strategies that are non-disruptive but inefficient. We demonstrate the effectiveness of our technique through a user study with N = 16 participants and two representative examples of mobile apps that commonly integrate advertisements (a game and a news app). Results from the study demonstrate that our approach can improve perception towards advertisements by 43.75% without affecting application interactivity while at the same time increasing advertisement effectiveness by 37.5% compared to a state-of-the-art baseline.Peer reviewe

User interface guidelines for the control of interactive television systems via smart phone applications

International audienceThere are a growing number of smart phone applications allowing the user to control their television, set-top box or other entertainment devices. The success of these applications is limited. Based on findings from media studies in Austria and France focusing on how people currently use their TV and iTV systems and associated devices, this article describes recommendations for the design of a smart phone application enabling users to control Internet Protocol Television (IPTV) systems including all connected entertainment devices. Recommendations include the need to allow users to control devices that are related to the IPTV experience (not only the set-top box or television set) and the focus on scenarios of usage like supporting listening to music, enjoying a movie or controlling the connected home. Based on similarities and differences found in the two samples, future smart phone applications for controlling TV will only succeed if they provide meaningful functionalities that satisfy the (varying) user needs, support personalisation and personal usage and respect the limitations of mobile phones with respect to possible parallel activities performed

Studies on Multi-Device Usage Practices and Interaction Methods

People today commonly have multiple information devices, including smartphones, tablets, computers, home media centers, and other devices. As people have many devices, situations and workflows where several devices are combined and used together to accomplish a task have become usual. Groups of co-located persons may also join their information devices together for collaborative activities and experiences. While these developments towards computing with multiple devices offer many opportunities, they also create a need for interfaces and applications that support using multiple devices together.The overall goal of this doctoral thesis is to create new scientific knowledge to inform the design of future interfaces, applications, and technologies that better support multi-device use. The thesis belongs to the field of Human-Computer Interaction (HCI) research. It contains five empirical studies with a total of 110 participants. The study results have been reported in five original publications. The thesis generally follows the design science research methodology.More specifically, this thesis addresses three research questions related to multidevice use. The first question investigates how people actually use multiple information devices together in their daily lives. The results provide a rich picture of everyday multi-device use, including the most common devices and their characteristic practices of use, a categorization of patterns of multi-device use, and an analysis of the process of determining which devices to use. The second question examines the factors that influence the user experience of multi-device interaction methods. The results suggest a set of experiential factors that should be considered when designing methods for multi-device interaction. The set of factors is based on comparative studies of alternative methods for two common tasks in multi-device interaction: device binding and cross-display object movement. The third question explores a more futuristic topic of multi-device interaction methods for wearable devices, focusing on the two most popular categories of wearable devices today: smartwatches and smartglasses. The results present a categorization of actions that people would naturally do to initiate interactions between their wearable devices based on elicitation studies with groups of participants.The results of this thesis advance the scientific knowledge of multi-device use in the domain of human-computer interaction research. The results can be applied in the design of novel interfaces, applications, and technologies that involve the use of multiple information devices

Leveraging contextual-cognitive relationships into mobile commerce systems

A thesis submitted to the University of Bedfordshire in partial fulfilment of the requirements for the degree of Doctor of PhilosophyMobile smart devices are becoming increasingly important within the on-line purchasing cycle. Thus the requirement for mobile commerce systems to become truly context-aware remains paramount if they are to be effective within the varied situations that mobile users encounter. Where traditionally a recommender system will focus upon the user – item relationship, i.e. what to recommend, in this thesis it is proposed that due to the complexity of mobile user situational profiles the how and when must also be considered for recommendations to be effective. Though non-trivial, it should be, through the understanding of a user’s ability to complete certain cognitive processes, possible to determine the likelihood of engagement and therefore the success of the recommendation. This research undertakes an investigation into physical and modal contexts and presents findings as to their relationships with cognitive processes. Through the introduction of the novel concept, disruptive contexts, situational contexts, including noise, distractions and user activity, are identified as having significant effects upon the relationship between user affective state and cognitive capability. Experimental results demonstrate that by understanding specific cognitive capabilities, e.g. a user’s perception of advert content and user levels of purchase-decision involvement, a system can determine potential user engagement and therefore improve the effectiveness of recommender systems’ performance. A quantitative approach is followed with a reliance upon statistical measures to inform the development, and subsequent validation, of a contextual-cognitive model that was implemented as part of a context-aware system. The development of SiDISense (Situational Decision Involvement Sensing system) demonstrated, through the use of smart-phone sensors and machine learning, that is was viable to classify subjectively rated contexts to then infer levels of cognitive capability and therefore likelihood of positive user engagement. Through this success in furthering the understanding of contextual-cognitive relationships there are novel and significant advances that are now viable within the area of m-commerce
