Basic research on prevention of wandering accident by using GNSS

摘要

As of 2018. the percentage of people over age of65 in Japan is over 25%. Since there are only a few nursing care facilities in Japan the patient's family often has to take care of them at home. Dementia patients tend to increase as older people increase, and more and more cases of which the dementia patients get an accidents has been reported. The purpose of our research is to prevent accidents of patients from missing by using GNSS. In this research we are conducting research with cooperation of local governments, doctor and family members of patients. Through the information exchange with them we got the current problems and the necessary information about the patient. Several companies, for example security and Telecommunication Company in Japan, are currently providing measures to prevent accidents from missing. However, such equipment recommended by those companies have several disadvantages such as high price, instability and the risk of information leakage. In this research, we proposed to use GNSS logger as a tool to solve these disadvantages. On the hospital information of our research assisted by the doctor, it was realized that wandering route tends to be different depending on individuals. The doctor who assisted our research suggested that wandering route tends to be different depending on individuals. Thus the research focused on the data of which the hospitals are profiling patients based on exercise intensity. On the other hand, GNSS logger can obtain information on movement trajectory and calorie consumption. On the experiments, both of these indicators are valid to the dementia patients were verified.
