ABSENTMINDED STATE DETERMINATION APPARATUS
First Claim
1. An absentminded state determination apparatus comprising:
- a data obtaining element for obtaining a time series data of a physiological characteristic value of a participant, wherein a fluctuation component is overlapped on the time series data, and the fluctuation component depends on a state of the participant including a normal state and an absentminded state so that the fluctuation component is changeable;
a detection element for detecting a plurality of reflecting portions of the time series data, wherein the plurality of reflecting portions reflect on the fluctuation component;
a counting element for counting the number of the reflecting portions of the time series data in a determination time period, which is disposed between a determination time and a certain past time; and
a determination element for determining according to the number of the reflecting portions at the determination time whether the participant is in the absentminded state,wherein the determination time period has a predetermined time width from the certain past time to the determination time.

Abstract
An absentminded state determination apparatus includes: a data obtaining element for obtaining a time series data of a physiological characteristic value of a participant, wherein a fluctuation component is overlapped on the time series data, and depends on a state of the participant including normal and absentminded states; a detection element for detecting reflecting portions of the time series data, which reflect on the fluctuation component; a counting element for counting the number of the reflecting portions of the time series data in a determination time period between a determination time and a certain past time; and a determination element for determining according to the number of the reflecting portions at the determination time whether the participant is in the absentminded state. The determination time period has a predetermined time width from the certain past time to the determination time.
