By embedding information technologies into tangible products a new class of products is created that we call smart products. Smart products use product information in product-centered communication with users. Communication of smart products is handled by dynamic product interfaces. We present a model for QA-based dynamic product interfaces and its implementation DyPI. It is based on a schema-d...

When it comes to usability evaluation of geodata information about its provenance or lineage are vital. Nevertheless, in practice the corresponding metadata elements are often neglected. Even if available, the tabular or listed metadata representations in current metadata catalogue user interfaces do not sufficiently support the users browsing and comparing metadata. This chapter proposes an in...

Modern Communication and Information Technology Infrastructure (CITI) provides key links and services to many other critical infrastructures [1], such as telecommunication, electricity, water supply, oil and gas networks, transportation, financial services, etc. Over the years, integration of these infrastructures with CITI has become pervasive, extensive, and complex. As such, failure in CITI,...

Context-aware systems use sensors in order to analyse their environment and to adapt their behaviour. We have designed and developed Sens-ation, an open and generic service-oriented platform, which provides powerful, yet easy-to-use, tools to software developers who want to develop context-aware, sensor-based infrastructures. The service-oriented paradigm of Sens-ation enables standardised comm...
