Goal Oriented Opportunistic Sensing
Today’s activity and context recognition system have the drawback to use a static sensing infrastructure that has to be defined at the design time of the system. The predefined sensing infrastructure needed to work properly, as well as the fixed recognition purpose limits the flexibility of such a system as it can’t react on changes in the sensing infrastructure nor it can address a change in i...
متن کاملGoal Oriented Opportunistic Recognition of High-Level Composed Activities Using Dynamically Configured Hidden Markov Models
The emerging availability of already deployed sensors that can be utilized for activity and context recognition raised a new paradigm. This paradigm called opportunistic sensing utilizes the available sensing infrastructure for activity and context recognition. This work focuses on utilizing this dynamically varying infrastructure to recognize high-level composed activities. The proposed method...
متن کاملOn the Utilization of Heterogeneous Sensors and System Adaptability for Opportunistic Activity and Context Recognition
Opportunistic activity and context recognition systems draw from the characteristic to utilize sensors as they happen to be available instead of predefining a fixed sensing infrastructure at design time of the system. Thus, the kinds and modalities of sensors are not predefined. Sensors of different types and working characteristics shall be used equally if the delivered environmental quantity ...
متن کاملDynamic Adaptation of Opportunistic Sensor Configurations for Continuous and Accurate Activity Recognition
An ever-larger availability of devices that are attached with different sensing capabilities (e.g., smart phones) shifted the challenge in activity and context recognition from the application specific deployment of new sensors to the utilization of already available devices. Therefore, a system that operates in an opportunistic way has to take advantage of the currently available sensing infra...
متن کاملReal-Time Transfer and Evaluation of Activity Recognition Capabilities in an Opportunistic System
This paper describes and evaluates the challenging feature of an opportunistic activity recognition system to train a newly discovered sensor with the available sensing devices to recognize activities at runtime. The term ”opportunistic” means that the system does not operate with a fixed set of sensor devices, but uses and configures the currently available sensors that just happen to be avail...
