An experimental lighting atmosphere was created for hospital consultation rooms to better support the shared decision making process of patient and clinician. The lighting atmosphere consists of two phases: (1) indirect, dimmed-warm light (supporting emotional expressiveness) and (2) direct, cold-bright light (supporting cognitive processing). The ambient lighting atmosphere was compared with a standard office lighting atmosphere involving 54 male participants. Participants took part in the experiment in pairs. During the first phase, they watched two emotion inducing film fragments and then discussed these fragments with each other. Under warm-dimmed lighting conditions significantly more emotions were expressed with less negative valence. During the second phase, participants performed two cognitive tasks. No statistical significant effects of lighting condition on both attention and concentration tasks were found.

Item does not contain fulltext Within the vision of Ambient Intelligence it is assumed that future electronic systems will be embedded into our lives and have different levels of intelligence. One class of systems that has reached such levels of embedding and intelligence are coaching systems for behavioral change. In this paper the findings of a field study are presented in which a coaching system is driven by data-analytics from sensor data. The study provides some first evidence that such coaching system is effective in guiding people to change their behavior. Additional, the study results enable the formulation of a statistical relationship between the test participant’s behaviors and the achieved adherence to the coaching target.

Emergent technologies allow gathering larger amounts of data from multiple sources, e.g., multi-sensor data and self-tracking data, that can be used for customization and personalization purposes. So far, the capacities of technologies to change behaviors and to continuously monitor the progress and effects of interventions are not yet being used to its full potential. The BCSS workshop series is the primary meeting for researchers and practitioners interested in how interactive technologies and services can influence people's attitudes and support positive behavior change. This interactive workshop acts as a forum where multidisciplinary researchers, practitioners and experts from a variety of scientific domains, such as information sciences, psychology, human-computer interaction, industrial design and medicine present their work, discuss and position new avenues for data driven persuasive coaching systems, e.g. to personalize healthcare. We present the pillars for persuasive technology and a holistic concept 'EPIC for Change': Engagement, Personalization, Integration and Connectivity for Change in individual and community care to create smart environments with persuasive technology for solving societal challenges.

Colors are widely used as feedback in ambient persuasive technology. In current research, we argue that the information that colorbased feedback carries is highly context dependent. Two studies investigated effects of context (in which color-based feedback was presented) on user’s interpretation of feedback messages, and more importantly, on the effectiveness of this feedback (for influencing energy conservation behavior). Results of both studies showed that participants perceived the color red in an energy-related context to be warmer and as related to a higher energy consumption level than red in an energy-unrelated context. Also, participants receiving color-based feedback in an energy-related context consumed the lowest amount of energy. These findings extend our insight into the psychological mechanisms of ambient persuasive technology by making clear that ambient stimuli (e.g., color) are part of a broader context (e.g., projected on a radiator) that influences user’s interpretation and the effectiveness of these stimuli.

Non-adherence is considered a problem that seriously undermines the outcome of behavior change therapies, in particular of self-help therapies delivered without human interference. This paper presents the design rationale behind a computer system in the domain of adherence enhancing strategies in automated e-coaching. A variety of persuasive strategies is introduced and implemented in a mobile e-coaching system in the domain of insomnia therapy. The system integrates two types of interface elements, i.e. dedicated tools and natural language conversation, to simplify therapy related activities and to include social strategies to improve motivation. We focus on the crucial role of communication and adaptation.

Lighting in video games is used to set moods and atmosphere, or can serve as a gameplay tool. This paper examines the effects lighting concepts can have on a virtual game environment on the players’ navigation within the game. Previously known lighting concepts were tested in a virtual environment to determine if they have a similar effect on the perception of the presented virtual space as they do in real life, as well as the effect they have on the navigational behavior of players. In a game-experiment with 50 male participants we show that the previously known lighting concepts apply to the virtual environment in a similar manner as they do in real life, although the effects on the navigational behavior of the participants remain inconclusive.

Cooperative driving for trucks has been claimed to bring substantial benefits for society and fleet owners because of better throughput and reduced fuel consumption, but benefits for truck drivers are questionable. While most work on cooperative driving focuses on the technology, the current paper focuses on the consequences for drivers and how to deal with those. Two concepts are proposed and evaluated. One concept supports drivers in coordinating cooperative driving with other truck drivers to locate, join, and quit platoons. The other concept provides drivers of following trucks with situation awareness by means of a "see through" system displaying camera images from the lead vehicle. A user evaluation in a driving simulator confirms that cooperative driving may have largely negative benefits for truck drivers, and that concepts such as the ones described in this paper may help to improve the cooperative driving situation for truck drivers.

This volume contains the papers and posters selected for presentation at the International Joint Conference on Ambient Intelligence (AmI 2012) held in Pisa in November 2012. The vision of ambient intelligence is to provide environments enhanced by intelligent interfaces supported by computing and networking technology embedded in everyday objects, and which enable users to interact with their surroundings in a seamless manner. More specifically, such environments should result in systems that are aware of the characteristics of users, recognize their needs, learn from their behavior, and are able to intelligently and even proactively act in order to support humans in achieving their goals. Ambient intelligence should also be unobtrusive - interaction should be natural and engaging for the users. From a scientific point of view, ambient intelligence (AmI) comprises a multidisciplinary approach covering fields such as computer science, human computer interaction, electrical engineering, industrial design, behavioral sciences, aimed at enriching physical environments with a network of distributed devices, such as sensors, actuators, and computational resources, in order to support users in their everyday activities. From a technological perspective, AmI represents the convergence of recent achievements in ubiquitous and communication technologies, pervasive computing, intelligent user interfaces and artificial intelligence, just to name a few. This conference started as the European Symposium on Ambient Intelligence in 2003, and has grown to an annual international event that brings together researchers and serves as a forum to discuss the latest trends and developments in this field. These AmI 12 proceedings include the latest research into technologies and applications that enable and validate the deployment of the AmI vision. This year the program contained 18 full papers carefully chosen from a total of 47 submissions (38% acceptance rate). There were also five short papers accepted out of 14 (acceptance rate 36%). All papers were reviewed in a doubleblind review process. For some papers this included a conditional acceptance step which required further revisions finally checked by reviewers and Chairs. In addition, the program included five landscape papers (papers that brainstorm on the future evolution of AmI), ten posters, and two demos. The competition for paper acceptance was strong and final selection was difficult. The published material originates from 27 countries, including Africa, Australia, North and Central America, Japan, Saudi Arabia, Singapore, and Europe. Each paper had at least two independent reviews from reviewers who were matched by expertise area to the topic of each paper. The Chairs handled borderline cases, and requested additional reviews when needed. In addition to the main conference, seven workshops were held prior to the main AmI 2012 event, and stimulated interesting discussions on specific relevant topics. A special thanks goes to the dedicated work of the 54 Program Committee members involved in the review panel who came from Europe and North America, thus reflecting the international spirit of AmI participation. Their names are listed in the conference proceedings and on the website. We would also like to express our gratitude to ACM SIGCHI, Interactiondesign. org, SIGCHI Italy, IFIP WG 2.7/13.4 for their help in creating interest in the conference. Finally, we would like to thank the conference Organizing Committee for their dedicated support, as well as the paper presenters and conference participants who contributed to the vibrant discussions, presentations, and workshops held at AmI 2012.

Ambient Intelligent environments are interactive environments that can sense human behaviour and can respond intelligently. This workshop explores how interactive environments can be designed with persuasive quality, hereby influencing human experience and behaviour. The workshop follows a research-through-design approach in which practise-relevant insights are gained while designing. The focus will be on intuitive and rational decision-making, the role of aesthetics in persuasion, social and spatial influences as well as technological influences on persuasion, evaluation methods for persuasion, and the ethics of designing for persuasion.

People suffering from dementia often have problems with way finding and feel restless. In this paper we present an interactive wall developed for decreasing the amount of wandering behaviour of people suffering from dementia. The installation aims at making these people feel more at home in the nursing homes by guiding them with a motion triggered audio path. This leads them to a wall with large windows displaying images and short movie tracks from their hometown. The results of an observation study show that the interactive wall succeeds in attracting people and thus reducing the wandering behaviour. Remarks of the elderly as well as their family and caretakers support this conclusion.
