Heart rate estimation device, psychological state determination device, heart rate estimation method, and program thereof

摘要

Provided is a technique for estimating a heart rate based on physical activity information that is not easily influenced by a psychological state, rather than physiological data such as an electrocardiogram or a pulse that is easily affected by the psychological state. A heart rate estimation device uses a sum total of past exercise amounts that affect a heart rate at a certain time as an exercise intensity estimate value, and uses a time series of the exercise amount of a subject in a period before an estimated time tk. Based on the amount of exercise performed by the subject, the exercise intensity estimator that calculates the exercise intensity estimate at the estimated time tk, and the heart rate-exercise intensity relationship model that shows the relationship between the exercise intensity estimate and the exercise intensity and the heart rate And a heart rate estimator for estimating the heart rate at the estimated time tk.
