LUNA uses advanced laser imaging technology to precisely monitor the activity status of the elderly without the need for a camera. It can classify lying, sitting, or getting out of bed three status. LUNA will immediately give a voice prompt and actively intervene in the process of the elderly getting out of bed to prevent falls when abnormality is detected. LUNA has helped reduce the fall rate at one hospital from 0.5 to 0.2, with significant results. LUNA's bed exit detection accuracy reaches 98.6%, far exceeding the less than 80% accuracy of similar products. This greatly reduces the stress on caregivers from repeated patrols. LUNA has obtained authoritative support from hospital clinical report and top-level scientific papers.
