abstract="Elderlies with wandered dementia who go out without permission sometimes meet accidents or get lost. This paper presents the presumption of elderly's movement using the function of acceleration sensor installed in mobile phone. This paper also introduces elderly's unstable movement which is causced by injury or accident, and presents the presumption of elderly's unstable movement and its evaluation. From experiments, elderly's movement was presumed about 91% using acceleration values and their spectra. By comparing acceleration spectra before and after falldown, elderly's unstable movement was presumed about 95%.Language: ja<p />",
