Today MIUI on Weibo announced that the Xiaomi Health app is upgraded to version 2.8.6 and added heart rate detection function, which is the first system-level heart rate detection in China. It is understood that Xiaomi Health’s heart rate detection without additional hardware, through the camera can measure the heart rate.

In terms of the principle, through the flash next to the camera as a continuous light source, the finger lightly pressed against the camera, you can get images of blood flow, and through image analysis, you can collect a stable pulse wave signal, to get the heart rate value.

According to the report, Xiaomi Health Heart Rate Detection can monitor Heart Rate with no additional hardware, will measure heart rate through the camera. It features as below:

Heart to Heart:  presents classified test reports according to different exercise states for more scientific heart rate evaluation.
Accurate and secure: Self-developed local AI heart rate recognition algorithm, accurate recognition, and protect your privacy at the same time.

Due to external factors such as temperature, skin color, arm shaking, there may be inaccurate test data or failure to generate results. Please take multiple measurements. The data is for reference only and is not a substitute for medical equipment.

In terms of supported models, except for the following models (Mi CC9e, Mi CC9Pro, Mi CC9 Meitu Custom Edition, Redmi 6A, Redmi 10X Pro), MIU12 models all support Xiaomi’s healthy heart rate detection function. The official said that the performance of the camera is different on different models. After testing, it is found that the unstable rate of the camera when collecting images will cause the result to deviate greatly from the true value. For better user experience, Xiaomi closed the heart rate test entrance on the above five models. Xiaomi will still find solutions and solve the problem as soon as possible.

Apple Inc and Google said they are putting stronger privacy protections in their upcoming contact-tracing tool for Covid-19 and that an early version will launch for developers next week.

The companies said the system’s tracking keys — a string of characters linked to a user’s device — will be generated in more random ways, and that Bluetooth data will now be encrypted, making it more difficult for individuals to be identified by hackers. Apps using the tool will also now limit the recording of the time people are exposed to an infected person to a maximum of 30 minutes.

The system unveiled two weeks ago, will add technology to the iOS and Android operating systems that alert users if they have come into contact with a person with Covid-19. The companies are now calling the technology Exposure Notification, a term they said more accurately describes the functionality.

The first phase — tools for public health apps to add contact tracing — will launch publicly in mid-May after an early beta version of the software is released to developers next week. In the coming months, the technology will be embedded more deeply into the Apple and Google operating systems to be less reliant on apps.

The companies also explained that if a person inputs that they have tested positive for Covid-19 into the system, they will be added to a positive diagnosis list so the system can notify other people they have come into contact with. They reiterated that the system doesn’t reveal a user’s identity or location to Apple or Google.

The companies are also adding new features for public health developers to build contact-tracing apps. The system will give apps data on the strength of Bluetooth signals so the distance between devices can be more accurately estimated. Developers will also be able to specify distance and time to determine what constitutes Covid-19 exposure for their apps. The tool will also determine how many days since a person has been exposed.

Apple said that the software update to enable the system will work on devices released in the last four years. Google said the tool will work with Android 6.0 or higher, which covers about 2 billion gadgets.

Amazon.com Inc on Thursday launched its first fitness band and app, Halo, as the e-commerce giant looks to take on Apple, Fitbit and Samsung in an increasingly crowded fitness tracker market.

The Halo band, which does not feature a display screen unlike most of its rivals, is priced at $99.99, while the app membership costs $3.99 per month, Amazon said.

The scope of growth in the fitness band market has prompted tech giants such as Apple Inc and Samsung to introduce many sophisticated features for health tracking, including electrocardiogram and blood pressure sensor.

In comparison, Amazon has featured a relatively new technology in the market called tone analysis, which reviews users’ tone during conversations. When enabled, a microphone on the band listens to detect emotions such as happiness, confusion or affection in the speaker’s tone.

It remains to be seen if consumers would embrace this feature or would it spark privacy concerns. Amazon said the technology was designed in a way that protects privacy.

The company said the water-resistant band, with a battery life of up to 7 days, also contains an accelerometer, a temperature sensor, a heart rate monitor and can measure body fat percentage.

Alphabet Inc-owned Google is also making strides into the fitness market. Google in November said it would buy Fitbit Inc for $2.1 billion, a deal that is currently under regulatory scrutiny.

The market is also crowded by cheaper offerings from China’s Huawei Technologies Co Ltd and Xiaomi Corp.
