Recent piano teaching systems mainly rely on MIDI data. However, MIDI data contains only little information about the student's movement. Therefore, additional data channels can potentially be valuable for future piano teaching systems. In this paper we have examined the question, if inertial measurement sensors attached to the piano student's arm...

The visualization of arm movement can provide valuable additional information for piano teaching. However, movement visualizations are often difficult to understand for musicians. SYSSOMO uses score-following to synchronize two performances of the same piece in order to overlay motion data, MIDI, and video. Using this technique, the user can easily...

Das Einüben verschiedener Bewegungsmuster ist ein wichtiger Teil beim Erlernen des Klavierspiels. Die erlernten Bewegungsmuster werden beim Spiel vom Musiker abgerufen. Eine automatische Erkennung dieser Muster könnte neue Anwendungen in den Bereichen Klavierpädagogik, Musikpraxis und Musikermedizin ermöglichen. Wir präsentieren frühere Studien bei...

Recognition of instrumental playing movements has recently drawn attention, especially in the domain of bowed string instruments. Peiper et al. have used decision trees to classify bowing movements [1]. Rasamimanana et al. have used k-NN (k-Nearerst-Neighbours) in a feature space spanned by minimal and maximal

PCRP (Parameter Controlled Remote Performance) is a new method to play music together on the Internet despite high delay. In many musical forms, the score of the piece is known beforehand. PCRP measures the deviations of the players from the given score and describes them as parameters. The parameters, which are transmitted instead of the audio dat...

Kontextbezogene Systeme stellen einen wichtigen Baustein des Ubiquitous Computing dar. Um prototypische Systeme und Anwendungen entwickeln zu können, ist die Untersuchung und Auswahl von Ortungssystemen als "Kontextquellen" wesentlich. In diesem Paper werden unterschiedliche Verfahren zur Orts- und Lagebestimmung diskutiert, die in unserer Gruppe e...

The Internet of Things (IoT) and the Internet of Services (IoS) are two well-known exemplars of the emerging 'Internet variants'. These variants will be tightly interwoven yet specific with respect to the supporting technologies needed. The present paper discusses the five variants identified as essential by the authors: IoT, IoS, Internet-of-Human...

Modern collaboration applications have a multitude of QoS requirements. Depending on the application module, such as messaging, collaborative modeling, or multimedia conferencing, the networking requirements are different. Such applications can greatly benefit from middleware which allows for configuring and using multiple communication stacks from...

Network latency is one of the most critical factors for the usability of mobile SOA applications. This paper introduces prefetching and caching enhancements for an existing SOA framework for mobile applications to reduce the user perceived latency. Latency reduction is achieved by proactively sending data to the mobile device that could most likely...

Subject-oriented business process management (S-BPM) introduces a new technique for process modeling that emphasizes the importance of the actors in business processes (subjects) and gives a balanced consideration to subjects, their actions, and goals. Because of the formal foundation and the clear declaration of subjects, S-BPM allows the distribu...

The Internet of services introduces new requirements for service engineering in terms of addressing both business and technical perspectives. The inherent complexity of the new wave of services that is emerging requires new approaches for an effective and efficient service design. In this chapter a novel service engineering framework is introduced:...

Developing applications comprising service composition is a complex task. Therefore, to lower the skill barrier for developers, it is important to describe the problem at hand on an abstract level and not to focus on implementation details. This can be done using declarative programming which allows to describe only the result of the problem (which...

Next generation SOA systems promise to enable an "Internet of Services" (IoS)-an open environment, in which every participant is free to offer and consume services. It is vital for businesses to ensure process compatibility and to have the ability to quickly adapt to changes in service offering. This raises the need for new service and process desc...

Employees are increasingly participating in business processes using mobile devices. Often, this is supported by a mobile web application, which accesses various web services in the back-end. The high latency of the mobile network (e.g., EDGE) is perceived by the user each time a web service is called, in addition to the time needed to invoke the s...

Augmented multitouch interaction provides a better user experience, but requires the integration of other input sources, e.g., a digital pen, each featuring an own API. Our approach to a multitouch table is realised as a service-oriented architecture combining these different aspects under the hood of a common API. Their use make our table work wit...

Next generation SOA systems promise to enable an “Internet of Services” (IoS) - an open environment, in which every participant is free to offer and consume services. Such an IoS gives businesses the opportunity to outsource parts of their internal processes and to replace them by using external services. However, businesses must ensure that extern...

Next generation SOA systems promise to enable an "Internet of Services" - an open environment, in which every participant is not only free to offer and consume services, but also to provide central components of the ecosystem, such as marketplaces and community portals. In such an environment with no or only very little central control, malicious u...

Location-aware software has become widespread outdoors. Indoor applications are now on the rise. However, careful selection of the appropriate local positioning system (LPS) and application fine-tuning are required in order to guarantee acceptable user experience. We present a simulation-based approach that includes application characteristics, LPS...

Reliable communication systems are one of the key success factors for a successful first response mission. Current crisis response communication systems suffer from damaged or destroyed infrastructure or are just overstressed in the case of a large scale disaster. We provide an outline for a distributed communication approach, which fulfills the re...

Ubiquitous computing spaces, which have displays gener- ously embedded into the environment, allow interaction with graphical user interfaces in a much more casual manner than desktop computers, which tie the user a particular desk. But simply putting desktop applica- tions on a ubiquitous display will not make their use casual. We propose applicat...

Developing applications comprising service composition is a complex task. Service composition requires the knowledge of various process languages (e.g. WS-BPEL, XPDL, or WSFL) or the knowledge of languages like WS-CDL which focus more on messaging aspects. To choose the right language for the problem at hand requires a lot of research as different...

Over the past few years, several technological advances have been made to enable locating people in indoor settings, where way finding is something we do on a daily basis. In a similar way as it happened with GPS and today’s popular outdoor navigation systems, indoor navigation is set to become one of the first, truly ubiquitous services that will...

The World Wide Web has changed the world. It has changed the ways we communicate, collaborate, and educate. We increasingly live in a Web-dependent society in a Web-dependent world. The Web is also the largest human information construct and it is growing ...

The focus of the workshop was to bring together experts of diverse areas such as Ubiquitous Computing, Product Engineering, Cognitive Science, Human Computer Interaction, Economic...

Ubiquitous Computing assumes that users and their computing devices are highly mobile. Because it is unlikely that mobile networks will be equally available in the same quality everywhere, there may be varying levels of connectivity, ranging from full network availability through low-bandwidth connectivity, to no connection at all. As a consequence...
