Logging users' physical context through the sensors of mobile devices and the abilities to track users' online behavior has increasingly evolved. In this poster abstract we will present a work in progress in understanding how various stakeholders can be connected through context logging technologies, and the underlying motivations. We will (1) describe the general components and information flow of context logging systems, (2) frame the primary stakeholders from the context logging point of view, (3) discuss the application areas through the different stakeholders and their goals for applying context logging. Moreover, we will present ContextLogger3, a context-logging tool that combines automatically acquired sensor and mobile activity data and manually user created textual notes.

Digital memorabilia, such as video remixes, can increase the value of attending music events. Remixes can be made using video clips recorded by attendees during the event; however, producing them is a laborious task. In this paper we study the prospects of an automatic video remixing and present the results of a study on users' perceptions and attitudes towards collaborative automatic mobile video production. The three findings are as follows: People assess automatic video remix memorabilia as fairly equal to amateur-made manual ones, even if the manually-created video remixes are better in overall quality; as a remixing actor, a computer can be perceived to be more trustworthy than a human remixer; and, the quality of the video remix and the publication forum of the remix outcome plays a significant role when people are deciding whether or not they need public acknowledgement for their contribution. We conclude by discussing the design implications for collaborative automatic mobile video production.

Recording and publishing mobile video clips from music concerts is popular. There is a high potential to increase the concert's perceived value when producing video remixes from individual video clips and using them socially. A digital production of a video remix is an interactive process between human and computer. However, it is not clear what the collaboration implications between human and computer are.

The adoption of new technologies in primary schools has fallen behind in terms of children's everyday use of technology. The use of mobile phones has been proposed as a promising field for learning. To date, the mobile learning technologies have rarely been integrated with current educational practices, however. Here, we present the results of our intervention study in which a mobile hybrid media system that combines the use of the traditional printed book with the mobile phone was used in English as foreign language (EFL) education in primary school. The results revealed an increase in learning motivation but also some conflicts when the boundaries of the school world and everyday life were blurred through the use of new technology.

In recent years, we have seen the rise of Web 2.0, where users become co-creators and software turns into services. While Web 2.0 technologies and concepts have been studied separately, we suggest that the digital ecosystem they form together and the ways in which users interact with it in social contexts have not been made explicit. In this paper, we provide a conceptual model of a community and a digital ecosystem for boosting user-driven service business. To construct such a model, we first identify the key actors and their interactions by applying use case modelling. Based on that, conceptual modelling is used to sketch an illustrative model of the overall ecosystem. Finally, we use the field of bioinformatics to evaluate the model and to propose ideas for boosting user-driven service business in that field as well.

Human factors research has shown that automation is a mixed blessing. It changes the role of the human in the loop with effects on understanding, errors, control, skill, vigilance, and ultimately trust and usefulness. We raise the issue that many current mobile applications involve mechanisms that s

Social interaction is increasingly computer mediated. Part of the mediated interaction is being automated by the technology used, especially in mobile phone technology. Human factors research has shown that automation is a mixed blessing. It changes the role of the human in the loop with effects on
