- the "relaxed state” and “distraction state” corresponding to the stress release state correspond to states in which both the stress value and the amount of exercise are both low or high. Therefore, in the case of the stress release index SR based on the definition of formula (1), the value range where the stress release index SR is too high (i.e., the upper limit threshold Th2 or more) and the too low value range (i.e., the lower limit threshold Th1) are excluded.
- An intermediate value range corresponds to a stress release state.
- the apparent value of the subject's acceleration detected by the sensor 5 increases, and the amount of exercise is calculated to be higher than the actual amount.
- a state of high stress and low stress ie, passive state
- This state is caused by the sensor 5 not correctly measuring the acceleration of the subject itself (that is, erroneous measurement).
- the stress-relieving action detection unit 18 uses only the stress value in the case corresponding to such a passive state (that is, the state in which the stress-relieving index SR is equal to or greater than the upper threshold value Th2). If the stress value is equal to or less than the threshold value "Th_s", it is determined that the behavior is to relieve stress.
- the threshold Th_s is set to a suitable value pre-stored in the storage device 4 or the like, for example. For example, if the target person is a driver in a car, the stress-relieving action detection unit 18 determines that the subject is in the passive state when the stress-relieving index SR becomes equal to or greater than the upper threshold value Th2 due to the high amount of exercise. When the subject's stress value is equal to or less than the threshold Th_s, it is determined that the stress release behavior has occurred. The same applies to the case where the target person is in the front passenger's seat or the person who is traveling by train.
- FIG. 6 schematically visualizes the stress release index SR and the lower threshold Th1 and upper threshold Th2 based on the formula (1) on a two-dimensional map in which the vertical axis is the stress value and the horizontal axis is the amount of exercise.
- the stress release index SR decreases as the stress value increases and the amount of exercise decreases, and increases as the stress value decreases and the amount of exercise increases. Then, in the present embodiment, the stress-relieving behavior detection unit 18 determines that the stress-relieving behavior has occurred when the stress-relieving index SR is greater than or equal to the lower threshold value Th1 and less than the upper threshold value Th2.
- the value range determined by the lower threshold value Th1 and the upper threshold value Th2 which is recognized as stress relief behavior is the value range to which the "relaxed state” and "distraction state" shown in FIG. 5 belong. Thereby, the stress relief behavior detection unit 18 can suitably detect the stress relief behavior corresponding to the “relaxed state” or the “distraction state”.

- the parameters (the value of ⁇ in Equation (2)) for configuring each index calculation model are associated with each attribute category to be separated and stored in advance in the storage device 4 or the like. As a result, the stress-relieving behavior detection unit 18 can more accurately calculate the stress-relieving index SR in consideration of the subject's attributes.
- the stress-relieving behavior detection unit 18 switches the index calculation model used for calculating the stress-relieving index SR, for example, based on the living information of the subject. For example, if the life information is schedule information indicating whether or not the person is at work, the stress relief behavior detection unit 18 recognizes whether or not the subject is at work at the date and time for which determination is made as to whether or not the stress relief behavior is being performed. , an index calculation model selected according to the recognition result is used to calculate the stress release index SR. In this case, an index calculation model used for judging the stress relief behavior while the subject is working and an index calculation model used for judging the stress relief behavior while the subject is not at work are prepared in advance.
- an index calculation model is prepared in advance for each life pattern specified by the life information to be referred to, and the stress-relieving behavior detection unit 18 refers to the life information of the subject to specify the model.
- An index calculation model corresponding to the subject's life pattern during the subject period is selected, and the stress release index SR is calculated.
- noise during work also affects whether or not stress is released.

- the stress release behavior detection unit 18 can calculate the stress release index SR that preferably takes into consideration the difference in the amount of daily exercise of each individual. can.
- the stress relief behavior detection unit 18 sets at least one of the lower limit threshold Th1 and the upper limit threshold Th2 to the daily exercise amount. It may be changed based on the amount of exercise. In this case, for example, the stress relief behavior detection unit 18 increases the lower limit threshold Th1 as the amount of daily exercise increases. As a result, the stress-relieving behavior detection unit 18 can accurately determine whether or not there is a stress-relieving behavior even for a person such as an athlete or a physical worker who has a high amount of daily exercise.

図7は、通知部19が出力装置3に表示させるストレス発散確認画面の一例である。ここでは、一例として、通知部19は、ユーザが指定した日付(ここでは本日)における対象者のストレス発散指標SRの推移を表す指標グラフ表示領域51と、ストレス発散行動が検知された時間帯に関するテキスト文章を表すテキスト情報表示領域52とを、ストレス発散確認画面に設けている。通知部19は、ストレス発散確認画面を表示するための出力制御信号S2を生成し、インターフェース13を介して出力装置3に当該出力制御信号S2を供給することで、出力装置3にストレス発散確認画面を表示させている。
図8は、第1実施形態において情報処理装置1が実行するフローチャートの一例である。情報処理装置1は、例えば、図8に示すフローチャートの処理を、所定のストレス推定タイミングになったと判定した場合に実行する。
次に、上述した実施形態の変形例について説明する。以下の変形例は任意に組み合わせて上述した実施形態に適用してもよい。
ストレス発散行動検知部18は、ストレス発散行動のうち気晴らし型の行動に特化した検知処理を行ってもよい。
ストレス発散行動検知部18は、ストレス発散行動の有無を判定する場合に、ストレス発散指標SR及びその閾値に加えて、所定時間経過後のストレス値をさらに勘案してストレス発散行動の有無の判定を行ってもよい。
ストレス発散行動検知部18は、継続的にストレス発散指標SRに関する基準が満たされた場合に、ストレス発散行動があったと判定してもよい。
ストレス発散行動検知部18は、ストレス発散指標SRの時間変化をさらに考慮してストレス発散行動の検知を行ってもよい。
ストレス発散行動検知部18は、ストレス発散指標SRを、式(1)又は式(2)のように運動量とストレス推定値との比に基づき定める代わりに、ストレス推定値と運動量とを用いた減算処理に基づき決定してもよい。例えば、ストレス発散行動検知部18は、ストレス推定値と運動量とを夫々0から1までの値域になるように正規化した後、当該ストレス推定値又は当該運動量の少なくとも一方に所定の重みを乗算し、正規化及び重みの乗算後において、当該ストレス推定値を当該運動量により減算した値をストレス発散指標SRとして算出する。このように、ストレス発散指標SRは、ストレス推定値と運動量とを用いた種々の算出方法により決定されてもよい。
情報処理装置1は、運動量に基づくことなくストレス発散行動を検知し、その検知結果を対象者又は管理者に通知してもよい。
図9は、第2実施形態におけるストレス発散検知システム100Aの概略構成を示す。第2実施形態に係るストレス発散検知システム100Aは、サーバクライアントモデルのシステムであり、サーバ装置として機能する情報処理装置1Aが第1実施形態における情報処理装置1の処理を行う。以後では、第1実施形態と同一構成要素については、適宜同一符号を付し、その説明を省略する。
図10は、第3実施形態における情報処理装置1Xのブロック図である。情報処理装置1Xは、主に、ストレス値取得手段17Xと、ストレス発散行動検知手段18Xと、通知手段19Xとを有する。なお、情報処理装置1Xは、複数の装置により構成されてもよい。
