Microsoft is working on new technology that can analyze someone’s pulse simply using a video shot on a smartphone.
It’s not just the manufacturers of bracelets and smartwatches looking to capitalize on heart health. Still in the field of consumer electronics, Microsoft announced on Wednesday that it was working on a new system to track your pulse, but also your breathing, this time using a simple smartphone camera. .
A group of researchers from Microsoft Research, the University of Washington and OctoML, have worked together to develop a new way to track this data using not a heart rate monitor, but a simple camera. running on video. ” This approach uses everyday camera technology like webcams or portable devices.“, Thus indicates the firm of Redmond.
To do this, Microsoft uses a video of the person’s face and, based on pixel changes and light reflections, is able to assess the person’s heart rate. “A smartphone camera can capture this reflected light, and the observed changes in pixel intensity over time can be used to track down the underlying sources of those changes, such as the person’s pulse or breathing.” , Microsoft says in a blog post.
It is thus a system close to what we already have in the field of watches and bracelets connected with heart rate monitors based on photoplethysmography, capable of emitting and capturing green light reflected according to the rhythm. user’s heart rate.
Much more accessible data for the general public
For Microsoft, the main interest of this technology is its adoption by the general public. Watches and bracelets capable of measuring the pulse – and a fortioridevices with an electrocardiogram – are still rare on the market, unlike smartphones or webcams.“The development of these video-based non-contact vital signs measurements presents an opportunity for large-scale monitoring of physiological data.”, wants to believe Microsoft.
For the time being, this is still only a use in the context of research. Microsoft is well aware that such data should be particularly protected, since it would associate health data with the face of users. It is therefore not known when the general public will be able to access it directly on a smartphone, PC or tablet.
