In this article, you will discover how Nobi defines a fall, how detection works, and why this approach ensures fast and reliable escalations.
What
A fall, according to Nobi, is when a person unintentionally ends up at a lower level and remains sitting or lying on the floor for a configured number of seconds. When this happens, Nobi creates a fall escalation. Caregivers are alerted quickly after the incident via the escalation procedure.
Nobi does not detect motion. Nobi analyses poses.
Nobi's optical sensors takes an image every second, and Nobita every five seconds. The light then processes this image locally. The AI converts the person into a stick figure and analyses the position of the person in relation to the bed and the floor.
Nobi distinguishes three poses:
Standing
Sitting
Lying down (bed or floor)
When the system detects a person sitting or lying on the floor, it escalates. The speed of the fall does not matter. Slow falls are detected as well.
For Nobi to operate as a smart light with fall detection, the resident must give informed consent for the smart features. Learn more about smart monitoring here.
Why
Falls can happen in many ways. Some are sudden. Others are slow and almost silent. For example, a resident might slide down from a chair or gradually lose balance when getting out of bed.
Nobi’s fall detection focuses on posture. It looks at whether someone ends up on the floor and not how fast they fell. Because of this, Nobi detects both fast and slow falls.
Nobi monitors continuously in the background, ready to act when a real fall happens.
A typical shift with Nobi's fall detection
It is early afternoon. A resident stands up from a chair and gradually loses their balance. They slide down slowly until they are seated on the floor. There is no loud impact or sudden movement.
The Nobi light detects a person sitting on the floor and the system escalates. Caregivers receive a fall alert on the Nobi Mobile App or through their configured escalation channels.
Later that evening, another resident slips while getting out of bed. The posture changes from standing to lying on the floor. Again, Nobi detects the pose. Again, the system escalates.
Care teams respond quickly. No one had to press a button. No one had to shout for help. Nobi works quietly in the background. Ready to help your team with every shift.
