From: Mobile psychiatry: towards improving the care for bipolar disorder

Sensor Details Subgroup
Accelerometer Body worn tri-axis accelerometer can facilitate monitoring physical activity, posture and (if worn during sleep) sleep patterns. Wearable
Global Positioning System GPS can be used to obtain precise outdoor location. The information can be used to monitor changes in activity. Wearable
Bluetooth scanning Monitoring Bluetooth environment can provide insight into social encounters as well as augment the localisation process Wearable
Light detector The detector should distinguish between natural and artificial sources of light. Turning the light on and off can be a sign of insomnia, restlessness and other behaviours related to the disorder. Wearable/Environmental
Remote control devices monitor An Infra-Red detector capable of determining the speed of pressing buttons on a remote control (see Chapter 3). Environmental
Door switches Simple on/off devices to monitor usage of household items and (if placed on cupboards in food preparation areas) to provide information regarding eating habits. Environmental
Motion detectors Passive Infra-Red (PIR) devices to monitor indoor mobility as well as unusual activity. Environmental
Bed sensor This can be a pressure mat under the bed or a capacitive presence sensor embedded in quilts Environmental
