Title EMOTION ESTIMATING APPARATUS meetings
Abstract Provided is an emotion estimating apparatus that is capable of estimating, in a sophisticated manner, an emotion and the mental state of a measurement subject by using a non-contact pulse detection technology. The emotion estimating apparatus performs forced re-sampling processing of digital biometric data generated by converting heart rate signals to digital data after extracting, at an RR interval, data corresponding to one cycle, thus obtaining coefficients of harmonic components by means of a DCT conversion processing unit. A coefficient data array is obtained by removing, by means of LPF, AC components from said coefficients of the harmonic components. This coefficient data array is compared to a dictionary data group, which are characteristic quantities indicating an emotion or the mental state, thereby calculating the similarity therebetween, and thus, an emotion or the mental state of the subject is estimated on the basis of the heart rate signals of the subject.
Outline of related art and contending technology BACKGROUND ART
By a technician and for many operators, the fatigue state of the driver driving the motor vehicle is detected, the earlier estimate the risk of issuing a warning to the driver, the driver asleep at the wheel to prevent the development of the system has been promoted.
Patent Document 1 is, from the facial expression of the passenger and pulse rate, to estimate the feeling of the passenger, the vehicle occupant emotion corresponding to the control device is disclosed.Patent Document 2 is, in the non-contact bio-signal detection pulse is detected by the disclosed device.
