Abstract
A waking degree maintaining apparatus of this invention estimates a waking degree of a person on the basis of a correlation between brain waves and the reaction time or between the blinking frequency and the reaction time, and discriminates a drop in waking degree on the basis of the obtained waking degree. A stimulus according to the waking degree is presented to maintain the person in a waking state of a predetermined level. The waking degree of a person is recovered to a normal state, not only in a low waking degree state, but also in an over-stained state.
Claims15
A waking degree maintaining apparatus comprising:
- stimulus means for presenting a predetermined stimulus to a person in order to maintain the person in a waking state;
- first detection means for detecting a reaction time to the predetermined stimulus;
- second detection means for detecting a quantity which represents a physiological condition correlating to a waking degree of the person;
- first generation means for generating an estimated waking degree of the person, based upon the reaction time and the quantity;
- second generation means for generating an average value and a standard deviation of a distribution of a plurality of said estimated waking degrees;
- and
- determination means for determining a drop in waking degree in conformity with the average value and the standard deviation, and for causing said stimulus means to present a predetermined stimulus to the person, when the drop in waking degree is determined, so as to maintain the person in a waking state.
A waking degree maintaining apparatus comprising:
- stimulus means for presenting a predetermined stimulus to a person;
- first detection means for detecting a reaction time to the predetermined stimulus;
- second detection means for detecting a quantity which represents a physiological condition correlating to a waking degree of the person;
- first generation means for generating an estimated waking degree of the person, based upon the reaction time and the quantity;
- second generation means for generating a period of a waking degree rhythm and a standard deviation of a distribution of a plurality of said estimated waking degrees;
- and
- determination means for determining a drop in waking degree in conformity with the period and the standard deviation, and for causing said stimulus means to present a predetermined stimulus to the person, when the drop in waking degree is determined, so as to maintain the person in a waking state.
A waking degree maintaining apparatus comprising:
- first detection means for detecting a reaction time to a stimulus presented to a person;
- second detection means for detecting a quantity which represents a physiological condition correlating to a waking degree of the person;
- generation means for generating an estimated waking degree of the person, based upon the reaction time and the quantity;
- means for setting a stimulus amount according to the estimated waking degree;
- and
- means for presenting a stimulus corresponding to the set stimulus amount.
