A study recently published by Cleveland Clinic in the periodic JAMA Cardiology can give a little peace of mind to the owners of Apple watch concerned about monitoring their heart rates for health reasons. According to the survey, Apple's watch is the most accurate wrist device for measuring heart rate overcoming renowned rivals like the Fitbit bracelet.
The study brought together 50 healthy adults at 3 levels of activity (resting, walking and trotting on a treadmill) and compared the results of an electrocardiogram (the most accurate method for heart rate measurement) with those offered by Apple Watch, Fitbit Charge HR, Mio. Alpha and Basis Peak, as well as those of a chest monitor.
Predictably, the chest monitor won the test easily, yielding 99% accurate results compared to the electrocardiogram. Among the wristwatches, however, Apple Watch emerged as the winner: its accuracy rate was 90%, while other competitors saw an average closer to 80%, according to the study.
The researchers found that all devices showed a greater variation in measurements when subjected to intense activity, such as running, which is understandable, since movement can compromise skin contact that is essential for measuring heart rate. Still, even at the busiest times, Apple's watch was the one that best held the bar between wrist devices and presented the most consistent gauges. Point to Ma!

Still on the subject of Apple Watch, patents published today can give us clues about the future of smartwatch. The first of these has to do with the heart rate meter itself: Ma apparently has an idea how to make this component act as an identifier as well as a Touch ID that reads its vascular channels.
The patent published in U.S. Patent and Trademark Office (United States Patent and Trademark Office) describes a system in which light emitted by photosensors is reflected back to the device and then compares the information received with other previously saved data to identify the vascular map of the arm. from the user.
The record further describes possible movements by the user that the system would use as "triggers" to activate vascular identification, such as lifting the watch to eye height. This would be interesting for times like using Apple Pay on the watch, further increasing your security. Only one name is now missing; How about Blood ID? 😛

Well, the fact that the other patent issued today also has to do with the movement of Apple Watch users' arms. The company describes a system that would command functions on the watch or even the iPhone to which it is connected by wrist or hand movements.
In other words, Apple Watch would incorporate sensors that would detect small movements made with the wrist / hands by contracting or relaxing the area's muscles. Some of the examples offered are the famous telephone signal, with the thumb and little finger extended, that could make or answer a call, or with the hands closed and rotating to control, say, the volume of a song.
Would it be very interesting and futuristic, anyway?
