Original Abstract Submitted
An arrival time determining device that can accurately estimate a timing of arrival at a predetermined position. A mobile terminal includes at least a user motion determining unit , an estimated arrival time calculating unit , and an arrival time determining unit . The user motion determining unit determines a user motion (a stopped state or a boarding state) based on motion sensor information of the mobile terminal . The estimated arrival time calculating unit calculates a time (time A) at which the mobile terminal has arrived at a destination as an estimated arrival time tbased on a position of the mobile terminal and the user motion (when the user is in the stopped state). The arrival time determining unit determines the estimated arrival time tas a result arrival time tbased on the user motion (when the user is in the boarding state). The result arrival time tis used to next calculate the estimated arrival time t.
