Apparatuses and method for determining and using heart rate variability

摘要

In embodiments, a person's heart rate variability (HRV) is determined by analyzing different color channels of a video of the person's skin. Various statistics are then derived from the HRV. The person's HRV statistics are processed using comparison's with HRV statistics of other people with known athletic through sedentary lifestyles, to obtain the person's fitness index. An analogous processing is carried out using comparisons of the person's HRV statistics to those of people with known levels of proficiency in specific sports, to obtain the person's sport-specific fitness index for the person.
