MIT Researchers Can Tell How Fast Your Heart is Beating By Video Monitoring

Researchers at MIT are constantly finding ways to use technology to improve people’s lives. This particular one will probably be most useful to those who might need remote healthcare services one day.

After doing extensive work at MIT’s Computer Science and Artificial Intelligence Laboratory, these scientists explain that they have developed an algorithm that will allow them to determine a person’s heart rate based on a video feed of them. The system is so accurate it was able to determine the heart rate of people wearing a mask or who had their face blurred out.

MIT Measure Heartbeat

You might notice that your head might rock back and forth slightly when you’re seated. That’s a result of the blood rushing to your head with every beat of your heart. This phenomena is measured and then used to figure out your heart rate.

The method was evaluated on a group of 18 men and women with different skin tones, and the results were reportedly “nearly identical” to that of an electrocardiogram.

There’s a lot of potential with this technology. Aside from remote healthcare, it can also be used to monitor patients with sensitive skin, like the elderly or newborns. It can also be used to measure the time interval between beats, which is useful for monitoring patients who are at risk for cardiac events.

Korg announces Volca analog synth series, we go eyes-on

Korg announces Volca analog synth series, we go eyeson

Korg’s love of the mini-analog synth clearly remains strong as it’s added three more new ones to the fold — the Volca Beat, Volca Bass and Volca Keys (the clue to what they do is in the names). While some firms take a pro product and work down, making cheaper versions, Korg seems to take a different approach. It did the stripping-back thing when it launched its popular Monotron synth. Since then, it’s incrementally developed it back up into a whole category of its own, the latest iteration of which we apparently see before us here. The trio of mini-synths clearly take inspiration from the Monotribe groovebox that came before them, but are a step up in terms of design. Brushed metal finishes give them a vintage, almost Stylophone feel. The Volca Bass, in particular, looks almost too much like the legendary Roland TB-303 to be coincidence, and if we didn’t know better, we’d say the color scheme of the Beat echoes the TR-808. As we happened to be in Frankfurt, we couldn’t resist getting out hands on them, or as you’ll see past the break, at least trying to.

Fujifilm’s flexible Beat speaker diaphragm lets us roll up the rhythm

Fujifilm Beat allows for bendable speakers, lets us roll up the rhythm

While there’s been no shortage of rollable displays, rollable speakers are rare — the softness needed for a bendy design is the very thing that would usually neuter the sound. Fujifilm’s new Beat diaphragm manages to reconcile those seemingly conflicting requirements. The surface depends on a polymer that stays soft when the surface is being curled or folded, but hardens when subjected to the 20Hz to 20kHz audio range we’d expect from a speaker. Piezoelectric ceramics, in turn, provide the sound itself. The Beat system doesn’t have any known customers, but Fujifilm has already shown some creative possibilities such as a folding fan speaker or the portable, retractable unit shown above. If we ever see the day when we tuck a set of speakers into our pockets as neatly as we do our phones, we’ll know who to thank.
