This is the author's accepted manuscript. The final publication is available at Springer via http://dx.doi.org/10.1007/s00779-013-0698-3. Copyright @ Springer-Verlag London 2013.Context-sensitive (or aware) applications have, in recent years, moved from the realm of possibilities to that of ubiquity. One exciting research area that is still very much in the realm of possibilities is that of cloud computing, and in this paper, we present our work, which explores the overlap of these two research areas. Accordingly, this paper explores the notion of cross-source integration of cloud-based, context-aware information in ubiquitous computing through a developed prototypical solution. Moreover, the described solution incorporates remote and automatic configuration of Android smartphones and advances the research area of context-aware information by harvesting information from several sources to build a rich foundation on which algorithms for context-aware computation can be based. Evaluation results show the viability of integrating and tailoring contextual information to provide users with timely, relevant and adapted application behaviour and content

An examination of user-focused context-gathering techniques in recommendation interfaces

Attempts to capture context within applications take a wide variety of forms. While it is generally accepted that a user’s current context shapes how they perceive and interact with a system such as a recommender we here explore a novel method of interacting with the user to gain a conceptual understanding of their own frame of reference. By drawing on a more human-centric approach we show that users accept and participate in sharing of context readily as part of an interactive system

Ubiquitous Computing Capabilities and User-System Interaction Readiness: An Activity Perspective

Based on mobile computing technologies, ubiquitous systems enable people to access information anywhere and anytime. In addition to the capability of interactivity concerning inquiry processing based on user input through interfaces, ubiquitous systems may offer contextualization and personalization dealing with information filtering based on task contexts and user preferences, which help relieve user effort on the move. This study investigates how different combinations of these major ubiquitous computing capabilities affect user behavior. Using the unifying framework of Activity Theory, it conceptualizes user-system interaction as a tool-mediated activity, the different aspects of which are facilitated by interactivity, contextualization, and personalization. It is hypothesized that such capabilities shape user experiences including sense of control, motive fulfillment, and perceived understanding, which lead to how ready people are to interact with ubiquitous systems. The results from an experiment support the hypothesized relationships, and suggest that different capabilities are interdependent in their effects. The findings yield insights on how to take a systematic and balanced approach of ubiquitous system design to enhance user experiences

UBIQUITOUS SYSTEM CAPABILITIES AND USER READINESS: AN ACTIVITY PERSPECTIVE

Based on the basic premises of both human-computer interaction research and technology acceptance research, this study investigates the relationship between ubiquitous system design and user adoption. Using the unifying framework of Activity Theory, it conceptualizes user-system interaction as a toolmediated activity. From this perspective, interactivity, personalization and contextualization are the basic design features that enable a ubiquitous system to facilitate such an activity in different ways. It is hypothesized that these system capabilities shape major user experiences including sense of control, perceived understanding and motive fulfilment, which lead to how ready they are to interact with the system. The empirical results obtained from an experiment support the hypothesized relationships, and suggest that the system capabilities interplay with each other in their effects. The finding provides insight on how to balance the capabilities in the design of ubiquitous systems for different tasks and different users

Examination of interactive experience: Construction of physical and social presence in virtual environments

Interactivity seems to be a familiar concept, which partially explains its frequent use in discussions about new communication technologies and what they can bring to communication studies. However, interactivity research has yet to reach a comprehensive and concrete consensus concerning the antecedents and consequences of interactive experiences. The main objective of this research is to determine the factors responsible for fostering the interactivity experience in the multiuser virtual environments and to observe how this variance in interactivity will affect the formation of physical and social presence. The study also examines the possible relationship between physical and social presence via correlation analysis and uses a one-way ANOVA with Post-Hoc Tests to designate the effects of interactivity on physical and social presence

The impact of interactive technology on prosocial behavior

Background. Behavior performed with the prosocial intent of helping others holds benefits not only for the recipient, but also for the prosocial actor and the community around them. Despite these pervasive benefits, there is relatively little research on how interacting with computing technology can be used to facilitate prosocial behavior. Understanding this relationship between technology usage and prosocial behavior and the psychological processes underlying this relationship is the aim of this doctoral thesis. To this goal, over the course of four manuscripts, we examined the impact of different technologies (in the form of video games, interactive narratives, and an interactive online platform) on their users' experiences and prosocial behavior. Methods. In each manuscript we followed a similar core structure; We experimentally manipulated a form of technology to examine its effects. We collected data on psychological processes we believed to be crucial to the effect of technology on prosocial behavior. Finally, in three of the four manuscripts, we assessed prosocial behavior after interacting with the technology. Based on the individual research questions, the experimental designs were supplemented with additional methodologies, such as interviews, surveys, and longitudinal data collection. Results. We found that interactivity in games and interactive text-based narratives can lead to increased prosocial behavior, but that this effect only occurred when interactivity lead to more meaningful experiences. We found that narrative choices can lead to meaningful experiences when they create moral dilemmas with clear consequences for oneself or others. We learned that sending reminders to track daily prosocial behavior for three weeks correlates with increases in belief in one's ability to help others in everyday contexts. The strongest predictor for using an interactive platform meant to support prosocial behavior over time was the belief in one’s ability to impact change and the enjoyment of the technology itself. Enjoyment was also related to the likelihood to continue using the interactive platform. One’s belief in one’s ability to help others in everyday contexts did not predict prosocial behavior over time, but one’s belief in one’s ability to impact change did. Conclusion. Interacting with technology is by far not a silver bullet to drastically impact prosocial behavior. However, when designed to be meaningful, interactivity can affect the way a narrative is perceived and to which extent prosocial behavior will be shown following the interaction. Interactive technology has the potential, particularly when enjoyable, to support performing prosocial actions and engagement over time. One’s belief in one’s abilities to perform everyday prosocial actions and one's belief in one's abilities to impact change both play roles within the relationship between technology usage and prosocial behavior. In order to correctly harness the potential of these technologies, however, the complex reality of the variability of users' everyday contexts, as well as their unique capabilities, opportunities, and motivations need to be taken into account. While some technology is more likely to lead to prosocial behavior when it is meaningful, others will be more likely be effective, particularly over time, when they are enjoyable. Future research should further examine the relationships between different forms of self-efficacy, experiences of enjoyment and meaningfulness, their relationship with sustained prosocial behavior, and how they are affected by interactive technology
