The Wandering Detection and Diversion System is a technology created to monitor night-time wandering amongst individuals with dementia. This smart home system uses sensors to create automated cues and redirection for those with dementia, reducing the risk of night-time wandering.

Motion, contact and bed sensors detect the sleeper’s movements and when they get out of bed. Analysis of the sensor’s data will determine night-time wandering patterns. If a person gets out of bed and starts to wander other technologies are activated–a nightlight turns on, a voice message encourages them to return to bed, or an alert is sent to the caregiver, if necessary.
