HEART RATE VARIABILITY EVALUATION FOR MENTAL STATE ANALYSIS |
| 摘要 |
A system and method for evaluating heart rate variability for mental state analysis is disclosed. Video of an individual is captured while the individual consumes and interacts with media. The video is analyzed to determine heart rate information with heart rate variability (HRV) being calculated and being understood to be in response to stimuli from the media. The analysis of heart rate variability is based upon a sympathovagal balance derived from a ratio of low frequency heart rate values to high frequency heart rate values. Heart rate variability is analyzed to determine changes in an individual's mental state related to the stimuli. Heart rate variability is determined and thereby mental state analysis is performed to evaluate media. |

1. A computer-implemented method for mental state analysis comprising:
obtaining video of an individual; analyzing the video to determine heart rate information; calculating a heart rate variability value (HRV) based on the heart rate information; and evaluating a physiological arousal based on the HRV. |
