Claim Text:
1. An information processing device comprising: one or more processors configured to: acquire, from a position sensor, an immediate movement history which comprises time series position data; receive, from a memory, search data which comprises past time series position data; calculate a similarity, as a goodness of fit, between the immediate movement history and the past time series position data, wherein the goodness of fit is calculated based on distances between a first plurality of positions including a current position and at least one position preceding the current position in the immediate movement history and a second plurality of positions corresponding to the first plurality of positions, in the past time series position data and wherein the second plurality of positions are obtained by tracking back a number of positions from a predetermined position in the past time series position data; determine whether or not the goodness of fit calculated for the past time series position data and the immediate movement history is a predetermined threshold or more; and control an acquisition interval of the position sensor to acquire the time series position data according to the determination of the goodness of fit.
