Falls of care home residents are a continuous problem. Elderly care organisation Oktober has been using the Kepler Night Nurse (KNN) for several years to speed up the detection of a fall. KNN is a computer vision and artificial intelligence-driven detection system for body language that identifies residents in need of help and alerts on-duty healthcare staff. An assessment period at Oktober recently showed that KNN generated an alert for every single fall with 100% reliability. In addition, KNN reduced the number of false, erroneous or unnecessary alerts by 99%.
