Integrating aspect-orientation and structural annotations to support adaptive middleware

To anticipate or not to anticipate --- that is the question, regarding adaptive middleware in the area of ubiquitous computing. Anticipation can guarantee that both the adapted and the adapting component work together safely, but it limits the scenario space to some predictable well-known cases. This holds even more when statically typed languages are used, as we assume here. A second problem is a semantic gap between the business logic that triggers the adaptation and the technological demands of the adaptation that must be solved on the implementation level. We discuss current approaches and describe a new approach combining aspect-oriented programming with structural metadata to cope with both problems. An example illustrates how our approach will work in practice.

Step by step vs. catch me if you can — On the benefit of rounds in location-based games

When adapting existing table games for the mobile setting, there is a choice of either keeping the round-based approach of such games or giving it up and optionally replacing it with additional “magical” features only available for the location-based version of the game. Based on our experience in building a hide and seek game using both approaches independently in two research groups, we compare the two alternatives regarding the design as well as user experiences. The results are a helpful guideline for other attempts to adapt table games for the mobile setting.

Towards context-sensitive intelligence

Even modern component architectures do not provide for easily manageable context-sensitive adaptability, a key requirement for ambient intelligence. The reason is that components are too large – providing black boxes with adaptation points only at their boundaries – and to small – lacking good means for expressing concerns beyond the scope of single components – at the same time. We present a framework that makes components more fine-grained so that adaptation points inside of them become accessible, and more coarse-grained so that changes of single components result in the necessary update of structurally constrained dependants. This will lead to higher quality applications that fit better into personalized and context-aware usage scenarios.

Proposal for the 4th workshop on mobile gaming, mobile life --- interweaving the virtual and the real

Over the last few years we have witnessed the smartphone dominating the market, the rapid growth of mobile apps, a surge in mobile augmented reality and location-based apps, and burgeoning mobile communities. While mobile topics continue to provide rich research challenges, people and companies outside academia already use these apps regularly. This is due to the increased availability of affordable devices, applications and technologies that support the creation of mixed reality experiences. Thus a core theme of our workshop at ICEC 2012 is authoring mixed realities, designing mobile games and creating mobile experiences. We would like to assess how professional designers and developers, as well as academics and end users, are using the technology to connect the digital and the real in a mobile context.

Software Engineering of Pervasive Services

The second workshop about Software Engineering for Pervasive Services [1] is organized during the International Conference on Pervasive Services [2] in Istanbul, Turkey, on July 2007. The program includes an invited talk, 6 presentations and a discussion. The first workshop about Software Engineering for Pervasive Services [3] was organised during the International Conference on Pervasive Services [4] in Lyon, France, on June 2006. In 2006 the program of the workshop included an invited talk, 5 presentations and a discussion.

Object Technology for Ambient Intelligence and Pervasive Computing

This report summarizes the main activities held during the third workshop on object-technology for Ambient Intelligence and Pervasive Computing. The goals of this workshop series are to identify and discuss the impact of Ambient Intelligence on object-oriented technologies and vice versa. This report summarizes the scope of the workshop as well as the contents of the presented position papers, the discussions provoked by these papers and the brainstorm sessions that followed the presentations. In particular, groups of participants actively discussed issues such as context volatility, development process, and user involvement in adaptable applications.

Object technology for ambient intelligence and pervasive computing: language constructs and infrastructures

This report summarizes the main activities held during the second workshop on object-technology for Ambient Intelligence and Pervasive Computing held at ECOOP 2006. The workshop covered topics varying from low-level considerations such as garbage collection and object migration, via programming language infrastructure such as reflection and context-oriented programming, to engineering applications using maturing techniques such as aspects.
