Smart device and sensor network technology based on Bluetooth

An important premise of ubiquitous computing is that the use of sensors and elaborate perception techniques will play an important role in order to derive interesting and high-level context. The Smart-Its project therefore served as an enabler to explore the use of multiple sensors, distributed throughout the environment to make applications aware of the situation of the environment and the users. Therefore the research drivers started from an application perspective in order to investigate artefact-based collective sensing, perception and context recognition in diverse applications. This has on the one hand motivated the design of innovative applications in highly diverse application domains and on the other hand resulted in the development of several conceptual frameworks. As an example we briefly summarise two innovative applications investigated during the project:

- Proactive Instructions for Furniture Assembly demonstrates how physical artefacts with embedded sensing can collectively recognize states of their assembly and user actions. It illustrates embedding of user instructions as a naturally artefact-centred application, and it highlights closure between plans formulated in the virtual world, and activity in the real world.

- A-Life illustrates distributed sensing and context-awareness in an alpine rescue scenario. It demonstrates fusion of distributed sensors, perception of vital context information, and use of collective context to support rescue of avalanche victims.

Based on technology design experiences and exploration of application and use, the project developed several conceptual frameworks as for example the following:

- The Perception Framework provides layered abstractions for perception and recognition functionality. It constitutes a design and implementation framework for application that are based on distributed sensing, perception and context.

- The Semantic Proximity Hierarchy is concerned with contextual relationships and provides a framework for notions of how close entities are in context space.

- A Sensing Taxonomy was developed as a first step toward a design framework that helps artefact designers and application developers understand and evaluate sensing opportunities.
