translated from Spanish: Amazon creates a bracelet capable of listening to you, telling you if you’re angry and if you’re fat

It’s not a smartwatch because it doesn’t give the time but it can be perfectly confused with one. Halo is a new activity tracker created by Amazon that comes full of sensors and with which the company takes its first step in the world of wearable electronics and health.
At the out entrance it has the same capabilities as many activity trackers that are already on the market. Once set, an app on your phone can show the number of steps you’ve taken or the quality of your sleep. The wristband can also measure body temperature and heart rate and works for a full week between charge and charge.
But this wristband, which Amazon will initially sell only in the U.S. at a price of $99 (some features will require an additional subscription service of $4 per month), it also has more advanced features.
Inside, for example there are two microphones. Its function is to listen to the tone of voice of the wearer to detect if they are angry, cheerful or insecure, for example. In the phone app it will be possible to check the different moods throughout the day using this function.
Amazon ensures that voice clips used for analysis are not recorded, and perhaps more significantly, Halo does not support the company’s virtual assistant, Alexa. It also does not support third-party apps.
Another trick that Halo will be able to do – this one more advanced – depends on the app on the phone. Using the camera of your device the user will be able to capture a 3D model of his own body. With this model the app will calculate the percentage of body fat.
In order to make the model, the wearer has to wear tight sportswear and take four photos (front, back and sides) of her body. The app does this automatically using the device’s front camera if you leave your phone resting on a surface.
This system, which uses machine learning techniques, is twice as accurate as the body fat calculations that a digital weight can perform at home, the company assures, and the app will allow you to save a historical archive of these models in 3D to check how the body evolves throughout an exercise regimen or diet.
As with voice, these models are only stored on the phone. The user can decide whether to upload them, encrypted, to a remote Amazon server. The app recommends making these models every 2 weeks and is only available for over 18s.
In addition to these two functions, the application has a section dedicated to medical studies or challenges that can be subscribed voluntarily. Among the experiments, for example, the user can check the effect of caffeine ingested mid-afternoon on their sleep quality that night or how they affect different exercises to reduce their body fat or practice yoga to their mood.
At first Amazon will offer the wristband only to a limited number of users in the testing phase, with a discount on the final price of the device (it will cost $65) and without charging the associated service needed to access the tone of voice analysis feature or body fat measurements.
