1. An information processing apparatus, comprising:
a processor configured to:
acquire time series data of pulse rate intervals from pulse wave signals outputted from a pulse wave sensor worn by a user;
calculate a reliability degree of one of the time series data of the pulse rate intervals or a heart rate variability (HRV) index, wherein
the HRV index is calculated from the time series data of the pulse rate intervals, and
the reliability degree changes based on a deviation of a physical state of the user at a time of measurement of the pulse wave signals from a resting state; and
control a plurality of processing operations based on the calculated reliability degree.
