Development of schedule navigation system for rehabilitation

The lack of caregivers has become a social problem on a national scale in Japan because of increases in the population of elderly people. The caregivers are forced to bear a serious mental burden in helping patients with antenegrade amnesia. They make a schedule plan of daily life for the patients. The use of systems which increase the degree of self-reliance in the patient life can reduce the burden of the caregivers. We have newly developed a small computer system with a data-logger, voice recorder and speaker, which utters an indication voice to instruct the patient to lead his or her daily life. The paper deals with the development of a schedule navigation system, which can lead the patients to a self-reliant life at home.
