INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM

摘要

The objective of the present invention is to make it possible to suppress a decrease in accuracy when estimating an ovulation date and/or predicting a menstruation date even when body temperature fluctuates up and down before and after a timing of actual transition from a low-temperature phase to a high-temperature phase. This information processing device determines a short-term number of days and a long-term number of days such that, for body temperatures for a plurality of days, said temperatures having been measured during past menstrual cycles, a timing at which the short-term moving average is lower than the long-term moving average overlaps with a menstruation date. The information processing device specifies, for the moving average of body temperatures measured in a target menstrual cycle, a timing at which the moving average for the short-term number of days is higher than the moving average for the long-term number of days. The information processing device predicts the next menstruation date or estimates the arrival of an ovulation date on the basis of the specified timing.
