Device for Determining Emotions through Pupils

This patent relates to a device that measures the size of the viewer's pupils and determines their emotions. It uses reference data to correct the pupil size and eliminate the influences of breathing and pulse. This allows for a more accurate assessment of the viewer's emotions. The device consists of eye-tracking and pupil measurement equipment, brightness measurement devices, respiratory waveform meters, and pulse waveform meters.

• Technology that corrects pupil size with reference data
• Technology that eliminates the effects of breathing and pulse
• Technology that corrects for brightness effects

Conventional technologies struggled to accurately measure the viewer's attention and emotions. In particular, they were susceptible to the influences of brightness, breathing, and pulse, and were unable to eliminate these factors. As a result, it was challenging to accurately determine the viewer's emotions.

This patent provides a method for accurately determining the viewer's emotions by correcting the size of the viewer's pupils using reference data and eliminating the influences of breathing and pulse. The reference data is measured for each combination of brightness and gaze position, and the effects of breathing and pulse are corrected using a moving average.

• Technology that can determine emotions based on pupil size
• Technology that can eliminate the influence of breathing and pulse
• Technology that can correct for brightness effects
