Zusammenfassung: | To provide an information processor capable of accumulating in time series, vital data for executing analysis, for detecting a sign of drowsiness of a user.SOLUTION: An information processor comprises: an acquiring part for acquiring vital data of a subject which is measured at a prescribed cycle in a first period; a calculating part for calculating a cumulative value obtained by adding a value corresponding to certain time in a range since first time to second time, to a value obtained by subtracting from an average value of pieces of vital data in a second period corresponding to the certain time and being included in the first period, an average value of the vital data in the first period, and calculating and recording the cumulative value at a prescribed cycle; and a comparing part for periodically determining whether the cumulative value satisfies a prescribed condition related to a standard deviation of the vital data in the first period, and after starting the determination, if the prescribed condition is satisfied first, issuing an alert reporting which indicates that a sign of drowsiness is detected.SELECTED DRAWING: Figure 1
【課題】バイタルデータを時系列で蓄積して解析を実行することにより、ユーザの眠気の予兆を検出すること。【解決手段】情報処理装置は、第1の期間において所定の周期で計測される被測定者のバイタルデータを取得する取得部と、ある時刻に対応する、前記第1の期間に含まれる第2の期間における前記バイタルデータの平均値から、前記第1の期間における前記バイタルデータの平均値を減じた値を、第1の時刻から第2の時刻まで前記ある時刻に対応する値を加算した累積値を算出し、前記累積値を所定の周期で算出し記録する算出部と、前記累積値が、前記第1の期間における前記バイタルデータの標準偏差に係る所定の条件を満たすか否か周期的に判定し、前記判定を開始した後、最初に前記所定の条件が満たされる場合、眠気の予兆を検出したことを示すアラート通知を発行する比較部とを有する。【選択図】図1 |
