This paper presents a pervasive adventure production called Lost Lab of Professor Millennium that experimented with different kinds of interaction techniques evaluating how they affected the adventure experience. The paper further reflects on the practical organization of the production targeted for schools and students between 12 and 15 years of age. Groups of up to four teenagers navigated through thirteen different kinds of pervasive computing experiences in checkpoints sharing a device providing augmented reality (AR) (MapLens) on a physical map and an adaptive marker-based AR guidance. Based on a Professor who lost her technologies, the story of the adventure provided a unifying narrative also through her fish Linus guiding groups through a variety of tasks in the checkpoints. The production was evaluated with direct observations, different kinds of video recordings, interviews and questionnaires. The evaluation revealed how groups shared the devices and performed collaborative interactions with the devices. The production received positive feedback from all stakeholders, but in terms of feasibility had some drawbacks. The evaluation indicated that the marker-based AR guidance techniques is practical, reliable and easy-to-use, and can be also used as a storytelling or story enhancing technique.

Spaceify is a novel edge architecture and an ecosystem for smart spaces --- a technology that extends the mobile user view of today's common space services (e.g., WiFi) to a richer portfolio of space-centric, localized services and space-interactive applications.

To understand how implicit and explicit biofeedback work in games, we developed a first-person shooter (FPS) game to experiment with different biofeedback techniques. While this area has seen plenty of discussion, there is little rigorous experimentation addressing how biofeedback can enhance human-computer interaction. In our two-part study, (N=36) subjects first played eight different game stages with two implicit biofeedback conditions, with two simulation-based comparison and repetition rounds, then repeated the two biofeedback stages when given explicit information on the biofeedback. The biofeedback conditions were respiration and skin-conductance (EDA) adaptations. Adaptation targets were four balanced player avatar attributes. We collected data with psycho¬physiological measures (electromyography, respiration, and EDA), a game experience questionnaire, and game-play measures.

ICT has reshaped our society, and with the current accelerating development of technology, and its wider distribution throughout the globe, they will continue doing so even more. These changes in society are important for sustainability. They affect the physical way the society and the environment interact, but they also affect the way people think, learn and behave.We suggest that the persuasive power of ICT can be oriented towards change. For this purpose we define the concept of climate persuasive services as ICT applications that change personal attitudes regarding change and/or change behavior towards reducing greenhouse gases emissions. We consider mobile phones, pervasive sensors and social media as three key technological drivers for the development of persuasion applications.We have analyzed the use of persuasion principles in existing web and mobile applications forming three clusters: tracking carbon footprints, sharing goals and making green behavior easier. Based on this analysis, we suggest a more planned use of persuasive principles, and propose six different opportunities for improvement.

In this paper we present MAR (Mobile Augmented Reality) Toolkit as an easy-to-use augmented reality toolset for building multi-user mobile phone games. It is built on top of MUPE - Nokia-developed open source mobile platform based on Java - which considers the special qualities of mobile technology. MAR Toolkit contains four components, map interface (MAP), physical object tagger (POT), public display (PUD) and silent communicator (SIC).We have successfully demonstrated MAR Toolkit by implementing a game named as Mupeland Yard based on classical board game Scotland Yard. In user testing we found that common usability issues related to mobile technology and MUPE-platform troubled the tests. However, especially POT component raised interest among developers. We found that using graphical 2D-tags for providing location information for augmented reality games is a simple and robust alternative for more technology intensive GPS and cell-ID information.

In this paper, we describe a framework for a personalization system to systematically induce desired emotion and attention related states and promote information processing in viewers of online advertising and e-commerce product information. Psychological Customization entails personalization of the way of presenting information (user interface, visual layouts, modalities, structures) per user to create desired transient psychological effects and states, such as emotion, attention, involvement, presence, persuasion and learning. Conceptual foundations and empiric evidence for the approach are presented.
