Title Benefits of Dynamically Reconfigurable Activity Recognition in Distributed Sensing Environments
Abstract Identifying complex human activities of daily life using distributed ambient and on-body sensors is still an open challenge. A key issue is how to enable systems to scale to the large diversity and variety of human activities. A possible solution is to use dynamic reconfiguration to adaptively focus on the current scene and reduce the recognition complexity. In this work, we evaluate the potential in energy savings and performance gains of dynamic reconfiguration in a case study using 28 sensors to record 78 activities performed within four settings. Reconfiguration improves recognition performance by up to 11.48%, while reducing energy consumption by 74.8% by turning off unneeded sensors. Our results reveal a trade-off between recognition performance and energy saving for different reconfiguration granularities.
