  abstract = {Recommender systems are today an essential part of software applications used in everyday life and facilitate the decision-making process for users by personalizing the options from which they can choose. An emerging and rapidly growing application domain for these systems is health care, and the majority of research contributions related to health recommender systems are about preventive health care. However, some crucial areas in this domain have been mostly overlooked. One such area is mental health promotion, which, despite its critical importance, has a relatively negligible share in existing solutions and research. User stress and mood are fundamental concepts in preventive health care, and proper skills for coping with stress and improving mood are crucial for individual mental well-being, which is the central theme of this dissertation. Health recommender systems have high potential benefits in personalizing health-related recommendations and, especially, engaging users in behavior change processes. A health recommender system for health promotion and behavior change is a holistic system that, ideally, uses techniques from ubiquitous computing to provide pervasive health. Building a health recommender system, therefore, is a multidisciplinary effort that engages various areas, which we summarize as tracking, interacting, and personalizing components, and address them in this dissertation regarding our recommendation domain, stress reduction. In particular, we discuss three major contributions to the problem of building health recommender systems for stress reduction and mood improvement: (1) establishing proper ways to track user mood; (2) building one of the first interactive mobile health recommender system research platforms and providing an extensive holistic dataset for flexible investigation of health recommender systems in the future; and (3) developing dynamic mood and health-aware, user-engaging algorithms and carefully comparing the performance and characteristics of the presented techniques. These contributions were the result of various mixed and longitudinal user studies which engaged with more than 2,500 users. This dissertation brings together for the first time various aspects of user decision-making - such as explicit short-term preferences, health needs, and long-term goals - for a holistic health-aware recommender system. By thoroughly discussing various components, this dissertation presents a roadmap for building health recommender systems, and interactive, mood-aware, and mental health-promoting systems in the future.},

  abstract = {With the growth of interactive text or voice-enabled systems, such as intelligent personal assistants and chatbots, it is now possible to easily measure a user’s mood using a conversation-based interaction instead of traditional questionnaires. However, it is still unclear if such mood measurements would be valid, akin to traditional measures, and user-engaging. Using smartphones, we compare in this paper two of the most popular traditional measures of mood: International PANAS-Short Form (I-PANAS-SF) and Affect Grid. For each of these measures, we then investigate the validity of mood measurement with a modified, chatbot-based user interface design. Our preliminary results suggest that some mood measures may not be resilient to modifications and that their alteration could lead to invalid, if not meaningless results. This exploratory paper then presents and discusses four voice-based mood tracker designs and summarizes user perception of and satisfaction with these tools. \textcopyright 2020 Owner/Author.},

  abstract = {Recommending personalized running routes is a challenging task. When the runner’s specific background as well as needs, preferences and goals are taken into account, a recommender cannot only rely on e.g. a set of existing routes ran by others, but needs to individually generate each route while considering many different aspects that determine whether a suggestion will satisfy the runner in the end, e.g. height meters or areas passed. We describe a framework that summarizes these aspects, allowing to generate personalized running routes. Based on this framework, we present a prototypical smartphone app that we implemented to actually demonstrate how running routes can be recommended based on the different requirements a runner might have. A first small study where users had to try this app and ran some of the recommended routes underlines the general effectiveness of our approach.}

Despite the accurate HRV detection by various body-attached sensors, a contactless method is desirable for the HCI purposes. In this research, we propose a non-invasive contactless HRV measurement by Microsoft Kinect 2 sensor with Respiratory Sinus Arrhythmia (RSA) correction. The Infrared and RGB cameras are used to measure the heart rate signal, and its 3D Depth sensor is employed to capture the human respiratory signal to correct the initially calculated HRV with RSA. The correlation analysis among the calculated HRVs by different methods and devices showed a significant improvement in reliable HRV measurements. This study enlightens the researchers and developers to choose a proper method for HRV calculations based on their required accuracy and application.},

  abstract = {Kaum eine Entwicklung wird Deutschland in den kommenden Jahren so prägen wie der demografische Wandel.“ Mit diesem Satz leitete ein Dossier des BMBF das Wissenschaftsjahr 2013 – Die demografische Chance – und damit den ansteigenden gesellschaftlich-politischen Fokus auf Maßnahmen zur Adressierung des demografischen Wandels ein. Gleichzeitig wird mit dem Wissenschaftsjahr 2014 – Die digitale Gesellschaft – ein Trend hinsichtlich der Erforschung von Technologien für ein selbstbestimmtes Leben in einer digitalen Welt aufgegriffen. Forscher und Entwickler im Bereich AAL verfolgen weitreichende Aktivitäten, welche insgesamt darauf abzielen, die Lebensqualität in einer sich wandelnden Gesellschaft durch innovative und praxistaugliche Technologien sicherzustellen. Eine zentrale Herausforderung ist die Identifikation und Sicherung der Rolle(n) älterer Menschen in einer funktionierenden Gesellschaft. Technologische Entwicklungen und Forschungsergebnisse der Mensch-Technik-Interaktion sollen hierzu einen Beitrag leisten. Aufgrund der zunehmenden Technisierung im beruflichen Alltag nimmt der Bereich CSCW einen wachsenden Stellenwert ein, da er unterstützende IKT für erfolgreiche Zusammenarbeit unabhängig von Alter und Erfahrung im beruflichen Alltag aufgreift. Aufgrund der divergierenden Akzeptanz und Kenntnis neuer Technologien unter älteren Menschen steigt die Bedeutung von Fragestellungen im Rahmen des AAL auch unter beruflichen Gesichtspunkten. Eine Herausforderung ist hier verschiedene Potenziale der Zusammenarbeit und der sozialen Interaktion mit den speziellen Anforderungen der Nutzer zu vereinbaren. In Hinblick auf die oben beschriebenen Perspektiven im AAL-Bereich sollen aufbauend auf den Ergebnissen der vergangenen AAL-Workshops auf der M&C Problemstellungen und Lösungsansätze dargelegt sowie neue Potenziale analysiert, diskutiert und dokumentiert werden. Der Workshop zielt ab auf die Erfassung zukünftiger Trends des AAL-Bereichs, insbesondere in Bezug auf den Umgang von Senioren mit Technologien im Rahmen des CSCW, deren Auswirkungen auf psycho-soziale Systeme sowie den interaktiven Austausch über aussichtsreiche Forschungsschwerpunkte und die Vernetzung der beteiligten Akteure.},

Serious games are often classified by benefits or purpose within a specific application area, but classifications focused on different user- and game-specific aspects are still rare. In this paper we provide an overview on a selection of serious games for elderly people by extracting and summarizing common categories used to classify games on a general level and especially serious games. Furthermore, a collection of serious games for elderly based on literature research as well as a classification using the summarized categories is presented. By those means, serious games for elderly shall be structured and not sufficiently covered approaches of providing benefits be identified.},

Furthermore, some games focus on strengthening motivation of patients to attend a specific medication or to change their daily behavior in order to live healthier. In this paper we present the health game “Balance”, developed to optimize the self-management of teenagers with diabetes mellitus type-I. Two versions of the game were implemented: A version explicitly referring to diabetes and an implicit version of “Balance” with no diabetes content in order to reduce diabetes related reactance among juveniles. In a between-subjects experimental study with a clinical sample the two versions were compared. Results demonstrate, contrary to expectations, that the explicit game version yielded higher game enjoyment than the implicit version.},

Based on this data, the simulation will be able to calculate the most energy-efficient route.},

  year = {2011},

  address = {München},
  abstract = {In this paper we introduce the prototype of a cognitive training environment called “Merobrixx”. Merobrixx is a serious game for players of all ages, including children and elderly people, based on traditional mental rotation training methods. Players interact with the game by means of a Tangible User Interface (TUI), which consists of three-dimensional objects made of LEGO bricks. A first evaluation of the system confirms that the user’s performance in the game is positively related to his or her general mental rotation ability. Based on these findings further research regarding the conditions for a long term training effect is planned.},

  year = {2010},
  publisher = {CEUR Workshop Proceedings ; 634},
  abstract = {This paper describes a camera-based approach towards
 creating a tangible interface for serious games. We
 introduce our game for dental health targeted at school
 children which implements the Nintendo WiiMote as
 infrared camera. Paired with a gesture-recognition system,
 this combination allows us to apply real-world items as
 input devices. Thereby, the game tries to address different
 aspects of dental hygiene along with the improvement of
 children’s motor skills. In our focus group test, we found
 that tangible interfaces offer great potential for educational
 purposes and can be used to engage kids in a playful
 learning process by addressing their childlike curiosity and
 fostering implicit learning.},

  abstract = {For the first time the track “Entertainment Interfaces” took take place together with the German HCI conference Mensch & Computer, the German e-learning conference DeLFI and the German Usability Professionals (UPA) track from 12-15 September at Duisburg.
 Within the past years the market of entertainment products has seen an overwhelming growth and has become an important part of the creative industries. This steady growth is not only based upon the changing demographics of users of interactive entertainment. One important reason is the diversification of interactive entertainment products converting more and more casual users into active consumers. The motion-sensitive controllers of the Nintendo Wii game console, the music instruments of Guitar Hero and Rock Band, and also products like Microsoft’s Natal which are currently in development offer innovative and user-friendly interfaces to attract new target groups. Computer- and videogames are not the only area the diversification changes: In the course of the growing media convergence new entertainment products evolve between the different fields of the creative industries. Interactive audio books, innovative toys and building blocks, game-based learning and serious games, virtual and augmented realities, and artistic installations and products give a first idea of the potential of this area.
 The track “Entertainment Interfaces” offers researchers, developers and designers a platform to present innovative ideas in the area of interactive entertainment with a focus on interaction in games and other entertainment products and to discuss design challenges and the evaluation of entertainment interfaces. The aims of the track are to strengthen the awareness of the relevance of user-friendly and innovative interfaces for entertainment applications in the research community and in the public, to encourage the research activities and the education in this field, and to foster the knowledge transfer between researchers and developers. We like to emphasize the interdisciplinary background of the “Entertainment Interfaces” track and welcome contributions from the areas of computer science, psychology, design and engineering sciences as well as contributions from developers and designers working in the field of interactive entertainment.},
