Selfie video measures blood pressure

In a study at the University of Toronto comparing blood pressure readings from an arm cuff sphygmomanometer and a two minute iPhone video with imaging analysis software, researchers found “on average, transdermal optical imaging predicted systolic blood pressure with nearly 95% accuracy and diastolic blood pressure with pulse pressure at nearly 96% accuracy.”  This was based on how well computational models worked, but it suggests a more convenient way of taking blood pressure measurement, though this comparison was done under ideal conditions.
