With the rapid growth of the aging population, the safety of the hospitalized elderly has become an important issue. Therefore, our team propose an innovative bed-exit alarm system using multiple sensors for bed-exit detection. With data fusion, IoT and AI technologies, the system can achieve early detection and significantly reduce false alarms. In addition, it can realize real-time video streaming with AR display, which facilitates the remote care for the elderly and provides qualified medical services.The traditional pressure sensing bed-exit alarm system often make false alarms owing to the different bodyweight of the patients. According to the medical journal report, this kind of product has a high false alarm rate of 30％. The high rate of false alarms interrupts the caregivers from time to time, increasing the burden of caring and discouraging them from using bed-exit alarm products. Therefore, our team propose the system combining machine learning and multi-sensor design to reduce the false alarm rate to less than 7％. In addition, real-time remote video and voice streaming are implemented with AR display, so that medical staff on duty can receive the alarm remotely and go to check the condition as soon as possible, providing a complete solution to prevent bed-exit falls.It is estimated that the system will significantly reduce the annual medical expenditure of NT＄ 2 billion due to reducing fall accidents and create NT＄ 1 billion in medical care aids to assist in the safe management of elderly care. The developed supervised AI algorithm technology can also be applied to other fields of fall prevention, such as chairs, stairs, and bathroom. Besides, through the cooperation with NCKU Transfer and Business Incubation Center, our team will facilitate the establishment of a medical aids startup company. Furthermore, creating a medical care output value of more than NT＄ 5 billion will achieve the goal of promoting the core technology development of our country＇s aids industry, and enhance the international competitiveness of our country＇s medical aids.
