Table 2 Sensors constituting the personalised ambient monitoring prototype
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 |
