Ambient and Wearable Sensor Fusion for Abnormal Behaviour Detection in Activities of Daily Living

Abstract: Abnormal behaviour in the performance of Activities of Daily Living (ADLs) can be an indicator of a progressive health problem or the occurrence of a hazardous incident. This paper presents an initial fusion approach of data collected from ambient (contact and thermal) and wearable (accelerometer) sensors in a smart environment to improve the recognition of the main steps of ADLs. An accurate recognition of these steps can support detecting abnormal behaviour in the form of deviations from the expected steps. … Show more

“…Garcia-Constantino et al fused data from a wearable accelerometer, contact sensors placed around a kitchen (on kettles, cups, doors, cupboards, containers) and thermal sensors placed on the ceiling [ 165 ]. This study involved 30 participants all performing the same action of entering the kitchen, preparing a hot drink, consuming the drink and leaving.…”

“…This study involved 30 participants all performing the same action of entering the kitchen, preparing a hot drink, consuming the drink and leaving. No other activities were recorded (no Null class) [ 165 ]. Drinking actions were detected with 95% accuracy, but the overall system accuracy for 4 classes was only 73.51% since entering and exiting were often poorly classified [ 165 ].…”

“…However, the features and window size for evaluating binary sensors [ 19 ] or wearable sensors [ 29 ] differ. For that purpose, it is necessary to provide ad hoc processing for each type of sensor data [ 30 ]. Automatic extraction of features, such as Convolutional Neural Networks, present similar or slightly lower results in daily activity datasets [ 31 ].…”
