Lip movements can be translated into text by smartphone.
And as a research team from Taiwan recently discovered, smartphone video recordings can help analyse messages contained in our blood flow.
Carotid arteries clogged up by fatty deposits restrict blood flow to the brain, potentially leading to strokes.
Such reduced moving patterns, although just below the skin, cannot be detected by the naked eye.
Hence the team’s use of an algorithm that enlarged the video recordings and searched for abnormalities at pixel-level.
First tests were 87% accurate in predicting artery blockages. If the software were globally available, symptoms could be detected earlier – and especially those without symptoms could be spared a heart attack.
Eye photos can be just as useful.
