But it’s all the various sensors inside those devices that are doing the actual measuring, calculating, tracking and reporting. Each has its own specialty providing specific functionality. I’ve always wondered about what’s inside some of the wearables let’s take a look at a few.
I noted that the accelerometer measures step count but what about those steps up a flight of stairs? Well, that would be the Altimeter. Altimeters measure altitude so it can sense changes in height. In conjunction with the steps the accelerometer counted, the altimeter will add its bits and give you a more accurate calorie count for those fire escape runs. Instead of asking how tall someone is, next time ask ‘What’s your alti?’
So you thought of attempting an Iron Man competition but wondered if your device could differentiate between the swimming, biking and running. You’re in luck if your device has a Gyroscope. Using the Earth’s gravity, it can help determine orientation. The big difference between an accelerometer and a gyroscope is that a gyroscope can also measure rotation or more specifically, the rate of rotation around a particular axis. Gyroscopes take into account the Earth’s gravity and rotation while the accelerometer does not.
There are a bunch of other sensors like Optical Heart Rate Monitors, typically worn on the wrist and it shines a tiny light against your skin to measure the blood pumping through your arm veins. And the various Gesture Tech things that use a little camera to see your hand and body movements to translate that into action on a gaming device, or a drone following your Snake River Canyon jump or even turning up the volume on the TV. It’d be cool to move something out of the way by effortlessly swiping your hand in the air, huh?
Sensors have been all around us for a while but now they are becoming close confidants. We should get to know our new Ohana.
