Development of Interactive Visual Communication Tools to Assist Caregivers

The number of people certified as requiring nursing care increases due to the aging of the population, a wide variety of products have been developed to support those requiring nursing care and their caregivers. Currently, systems such as nurse call systems have been developed in which a caregiver comes to the patient when the call button is pressed. However, caregivers with memory impairment who require nursing care need to remember the call's content by the time the caregiver answers the call. In this research, we developed a system to support people who classify as levels 1 to 3. The proposed approach is designed based on the caregiver's basic needs support by selecting one of four options: "toilet," "eat/drink," "hot/cold," or "call" from the specially designed user interface. The proposed friendly user interface in this research can easily be modified and clarify the individuality of each user and the needs of the nursing care site. The requested information will notify the nursing care site smartphones through the LINE account. We also evaluated the proposed system by doing experiments in the daily support center.
