PROBLEM TO BE SOLVED: To provide an information processing device capable of accurately measuring a heart beat, etc.SOLUTION: An information processing device connected to a measuring device for measuring a motion of a human body acquires first measurement data indicating a result of the measurement from the measuring device, detects an interval of peaks included in a waveform based on the first measurement data, estimates a reference peak interval that serves as a reference, acquires second measurement data indicating a result of the measurement from the measuring device, and identifies a combination of peaks in which a sum of differences between the reference peak interval and peak intervals by a plurality of peaks becomes minimum, of a plurality of peaks included in a waveform indicated by the second measurement data, based on Viterbi algorithm.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】心拍等を精度をよく計測することができる情報処理装置を提供する。【解決手段】人体の動きの計測を行う計測装置と接続する情報処理装置が、計測による結果を示す第1計測データを計測装置から取得し、第1計測データに基づく波形に含まれるピークの間隔を検出し、基準となる基準ピーク間隔を推定し、計測による結果を示す第2計測データを計測装置から取得し、第2計測データが示す波形に含まれる複数のピークのうち、ビタビアルゴリズムに基づいて、基準ピーク間隔と、複数のピークによるピーク間隔の差の和が最小となるピークの組み合わせを特定する。【選択図】図1
