Use Eye Tracker to Design an Intelligent Patient Bed

In the case of caring disable patients in hospital, transportation and security of a patient under supervision of a nurse is crucially important. We developed an intelligent patient bed here, with the assistance of contactless eye tracker which works to facilitate the communication between the disable patient and the bed for better self-care. In real time, it delivers information about the gaze position, where a designed Graphical User Interface (GUI) is used to catch the intention of user. After that, it is able to trigger a special service that the patient expects. The service embedded in the patient bed include the complicated positioning control and the call for a nurse. In addition, this patient bed is innovatively made of composite materials: carbon fibers to reduce the total weight for saving electricity and reduce the burden of transportation or positioning. Our efforts are valuable when the hospital moves toward the automation and intelligence via the technology from Internet of Things (IOTs).
