Abstract

An object of the present invention is to provide a human condition detecting apparatus for highly accurately detecting a human condition, without any burden. A human condition detecting apparatus of the present invention is characterized by comprising a first stimulus applying device 10 for applying a stimulus for acquisition of reference information to a subject; a second stimulus applying device 10 for applying a stimulus for acquisition of condition information to the subject; a stimulus reaction detecting device 20 for detecting reactions of the subject to the stimulus applied by the first stimulus applying device 10 and to the stimulus applied by the second stimulus applying device 10, by an ecological index of the subject; and a condition determining device 41 for determining a condition of the subject, based on a comparison between the reaction of the subject to the stimulus applied by the first stimulus applying device 10 and the reaction of the subject to the stimulus applied by the second stimulus applying device 10.

Claims

1. A human condition detecting apparatus comprising:

first stimulus applying means for applying a stimulus for acquisition of reference information to a subject;

second stimulus applying means for applying a stimulus for acquisition of condition information to the subject;

stimulus reaction detecting means for detecting reactions of the subject to the stimulus applied by the first stimulus applying means and to the stimulus applied by the second stimulus applying means, by a physiological index of the subject; and

condition determining means for comparing a physiological response of the subject to the stimulus applied by the first stimulus applying means, with a physiological response of the subject to the stimulus applied by the second stimulus applying means, and for determining a condition of the subject, based on a change between the physiological responses.

2. The human condition detecting apparatus according to claim 1, wherein the stimulus applied by the first stimulus applying means is periodically applied.

3. The human condition detecting apparatus according to claim 1, wherein the stimulus applied by the first stimulus applying means is applied before the second stimulus applying means applies the stimulus.

4. A human condition detecting method comprising:

applying a stimulus for acquisition of reference information to a subject;

applying a stimulus for acquisition of condition information to the subject;

detecting reactions of the subject to the stimulus applied for acquisition of reference information and to the stimulus applied for acquisition of condition information, by a physiological index of the subject;

comparing a physiological response of the subject to the stimulus applied for acquisition of reference information, with a physiological response of the subject to the stimulus applied for acquisition of condition information; and

determining a condition of the subject on the basis of a change between the physiological responses.

5. The human condition detecting method according to claim 4, wherein the stimulus applied for acquisition of reference information is periodically applied.

6. The human condition detecting method according to claim 4, wherein the stimulus applied for acquisition of reference information is applied before applying the stimulus for acquisition of condition information.
