It is quite common for millions of people to wear a smart watch or an active bracelet on their wrist, devices that have come a long way in recent times, but still cannot track the position of our entire body, although they can wear out. to do in the future

Now, researchers at Cornell University have created a wristband that can track the position of the whole body in 3D using just a miniature camera and also a neural network custom deep. You may see this technological breakthrough in the next smart watches and to find out how it works, Infobae brings this article to explain it in detail.

Called BodyTrak, it is an intelligent sensor device that can track the user's body mechanics in all their physical activities.

“Since smartwatches already have a camera, technology like BodyTrak could understand the wearer's pose and provide feedback in real time. It is practical, affordable, and does not limit the user's range of motion,” says Cheng Zhang, assistant professor of data sciences and lead author.

This bracelet-like bracelet consists of a coin-sized camera on the wrist and a deep neural network forming behind it. This neural network reads images from the camera or the silhouette of the user's moving body and can 3D and almost recreate 14 body positions in real time.

This is how the camera works that targets the user's body by collecting only partial images

To challenge and test the bracelet, they conducted a user study with nine participants, each of whom performed 12 daily activities such as walking, sitting, or exercising in different settings, wearing different clothing, and in different settings. camera.

Post-training results showed that the system can infer whole-body posture, especially 14-joint 3D poses, with an average error of 6.9 cm using only a miniature RGB camera on the wrist pointing at the body.

For those interested in privacy, they explain that their camera is pointed at the user's body and collects only partial images, which we will see in future activity bracelets.

This research group has previously developed deep learning models to track movements of hands and fingers, as well as facial expressions and silent speech recognition.

What are the reference points in the compass of the new Apple Watch and what are they for

The compass built into the Apple Watch It has other functions that consist of marking waypoints, locations that can be saved with names, special icons, colors and whose location will be marked in the  application .

In order to use this functionality within the Compass app on Apple Watch, users must follow these steps:< /p>

– Open the Compass app on the Apple Watch. For this to work, the device must be compatible with the new  watchOS 9 system.

– Touch the button the bottom left corner of the screen, that will open the tag options  menu.

– The user will be able to type the name  that you want in the tag to add to your list.

Reference points in the Apple Watch Compass application

– The waypoints can be customized to have different colors and icons to make it easier to tell them apart.

– Click the Ok button .

Once this process is done, users have the ability to touch these waypoints, access a  full list&nbsp ;of all those available on the tech machine and edit detailed content such as  information about the location of the point.
