The OPPORTUNITY Framework and Data Processing Ecosystem for Opportunistic Activity and Context Recognition
Opportunistic sensing can be used to obtain data from sensors that just happen to be present in the user’s surroundings. By harnessing these opportunistic sensor configurations to infer activity or context, ambient intelligence environments become more robust, have improved user comfort thanks to reduced requirements on body-worn sensor deployment and they are not limited to a predefined and re...
متن کاملA Framework for Opportunistic Activity and Context Recognition
Opportunistic activity and context recognition systems draw from the characteristic to use sensing devices that just happen to be available rather than pre-defining a fixed sensor infrastructure at design time. Opportunistic sensing offers the possibility to obtain data from sensors that just happen to be available in the area surrounding the user. This enables users or applications to state re...
متن کاملTowards a Framework for opportunistic Activity and Context Recognition
Due to recent advancements in the development of sensor devices which results in increasing mobility and computing power and decreasing size and costs, this paper presents two features for a sensor-based opportunistic activity and context recognition enabling framework. Opportunistic in this context means that no sensor infrastructure has to be predefined at the design time of the system, it ra...
متن کاملSensor Abstractions for Opportunistic Activity and Context Recognition Systems
Pervasive environments are inherently characterized to draw from sensor infrastructures in order to become situation aware. Very recent technological evolutions of sensor hardware (e.g. for geoposition, acceleration, orientation, noise, light, humidity, chemical properties, etc.) have fertilized an explosive growth of sensor infrastructures, introducing whole new challenges for sensor software ...
متن کاملGoal Processing and Semantic Matchmaking in Opportunistic Activity and Context Recognition Systems
The Opportunistic Sensing Paradigm shifts away the configuration of activityand context recognition systems from design time of the system to a dynamic runtime configuration. Systems following this new paradigm have to autonomously configure themselves during runtime according to a stated recognition goal and the available sensing infrastructure. A crucial point therefore is to find a methodolo...
