Viewer feeling determination device, viewer feeling determination system and program for eliminating influence of light and darkness, breathing and pulse

摘要

[PROBLEMS] To measure the pupil diameter excluding the effects of light and darkness, respiration, and pulse, and more accurately determine the emotion of the viewer. A reference data measurement unit 22 measures a reference pupil diameter Csk, a respiratory pupil diameter Dskt, and a pulse pupil diameter Eskt as reference data for each of the brightness of the entire screen and the brightness of the viewpoint. The measurement unit 23 specifies the reference pupil diameter Csk, the respiratory pupil diameter Dskt, and the pulse pupil diameter Eskt corresponding to the elapsed time of the content. The measurement unit 23 sets the pupil diameter Bt to the attention pupil diameter A1t when the respiratory time is 2 breathing times or more (T1), and from the pupil diameter Bt to the respiratory pupil diameter Dskt when the breathing time is 2 pulse time or more and less than 2 breathing times (T2). Is subtracted to obtain the attention pupil diameter A1t. In the case of less than 2 pulses (T3), the pulse pupil diameter Eskt is further subtracted to obtain the attention pupil diameter A1t. The measurement unit 23 subtracts the reference pupil diameter Csk from the attention pupil diameter A1t to obtain the attention pupil diameter A2t, divides the attention pupil diameter A1t and the attention pupil diameter A2t by the reference pupil diameter Csk, and obtains the attention degrees P1t and P2t.
