Smile! We know how fast your heart is beating

Have you ever noticed your head rocking back and forth very slightly when you sit still? That's the effect of blood rushing up to feed your brain.

Now Massachusetts Institute of Technology researchers can accurately measure that phenomenon on regular video and figure out how fast someone's heart is beating. They say it might help detect cardiac disease.

The scientists at MIT's Computer Science and Artificial Intelligence Laboratory believe the algorithm could be used for video monitoring of patients with sensitive skin, such as newborns or elderly people. … Read more

What a heart rate monitor says about your relationship

New research out of UC Davis suggests that when couples who are romantically involved interact, their heart and respiratory rates sync up.

But that doesn't mean you should bring a pair of heart rate monitors to scout out potential partners on your first date. When study participants were paired with someone outside their relationship, neither their heart rates nor their breathing closely matched.

To conduct their research, which was funded by the National Science Foundation and published in the International Journal of Psychophysiology and Emotion, the psychologists in one study placed couples a few feet apart in a quiet, calm room and instructed them not to talk or touch. In another, the couples were asked to mimic each other without speaking. In both instances, heart and respiratory rates were closely matched.… Read more

E-garment snoops on troops

Sit up straight. Be on time. Watch your blood pressure; wise admonishments all, yet hard to enforce--until now.

A new type of undershirt wired with an integrated system can now monitor an individual's heart and respiration rate, activity, GPS location, and even posture, then transmit the data to a supervisor or other concerned adult.

Where are they? How are they? These are questions the TrainTrak physiologic "garment-based" monitoring ensemble promises to answer, according to developer, QinetiQ. By updating real-time location and physiologic status the "e-garment" can help maintain "personnel accountability, increase situational awareness, detect … Read more

Smart scale tells how buffed you are

We generally try very hard not to think about exercise equipment when not at the gym (or even when we are at the gym, actually). But this is one fitness item that may be impossible for us to ignore.

If you've ever wondered what, exactly, your workout routine was doing for specific parts of your body, this intelligent scale from Tanita might interest you too. Far more than just indicate poundage, the new BC-545 model delivers "individual body composition readings for five body segments (each arm, each leg and the trunk area)," according to Gizmag. To get … Read more
