Information processing apparatus, digestion rate estimation method, information processing system, and digestion rate estimation program

摘要

An information processing device includes a first receiver configured to receive, from a heart rate signal measuring device carried by a user, a plurality of heart rate signal information items measured at predetermined time intervals; a second receiver configured to receive information of meal start time and meal end time of the user; a characteristic amount calculator configured to identify digestion end time indicating a time when a digestion of the food ends, based on the heart rate of the user at the meal start time and a trend indicated by the plurality of heart rate signal information items and indicating that the heart rate of the user increases and decreases over time after an end of the meal; and a digestion rate estimator configured to estimate a digestion rate based on the meal end time and the identified digestion end time.
