PROBLEM TO BE SOLVED: To improve the accuracy of determination by properly setting a section in which analysis is executed when analyzing a detection value of a sensor which detects physical behavior of a sensor device to determine a user's motion pattern.SOLUTION: An information processing device includes a sensor data acquisition part for acquiring first time series data including a detection value of a first sensor for detecting impact transmitted to a sensor device directly or indirectly worn by a user playing sport, and second time series data including a detection value of a second sensor for detecting physical behavior of the sensor device with resolution higher than the first sensor, and a section setting part for setting an analysis object section in which analysis for determining the user's motion pattern is executed in the second time series data, on the basis of the first time series data.
