Google Pixel Watch: A new breakthrough in smart watches that detects heavy falls and protects users

News on June 14, Google’s latest smart watch Pixel Watch, introduces a unique feature - fall detection. When the user suffers a heavy fall, the watch will proactively ask if medical assistance is needed and automatically make an emergency call. Behind this feature, Google’s product leader Paras Unadkat said that a large amount of data needs to be collected and artificial intelligence models trained to distinguish different types of movement patterns to understand what a "hard fall" is. To this end, Google has cooperated with some universities and laboratories that study the phenomenon of falls to build simulated fall devices, observe people's reactions when they lose their balance, and use computer vision technology to try to visualize different types of falls.

# According to the editor’s understanding, Google also takes into account physical factors, such as the different limb lengths and body shapes of humans. To better train the sensors inside the watch, Google even hired stuntmen to actually fall to the ground. Pixel The Watch has many tiny sensors built into it. They can not only sense the user's movement, but also monitor information such as heart rate, steps, and sleep, thereby identifying the human body's typical response in the event of a heavy fall.

To ensure that the watch doesn’t mistakenly identify users’ daily activities as emergencies, Google conducted extensive testing during the development process. For example, the watch can recognize high-intensity exercises such as jumping, swimming, and doing push-ups as normal activities to avoid false alarms of emergencies.

In order to allow users to get help quickly, Google officially released Pixel The Watch was previously tested for more than a year, involving hundreds of people. In addition, Google worked with the emergency response community to test the quality of calls automatically made by the watch to ensure that the voice was clear and the information was sufficient.

Pixel Watch was launched last fall, but it didn’t add fall detection until late February this year. In the event of a heavy fall, the watch will display two options: "I'm injured & Need help" and "I'm okay". It is worth noting that if the user is using the Wi-Fi version of the watch, he or she needs to be within the range of a Bluetooth connection to the mobile phone to contact emergency services.

Pixel Watch has added other health and safety features in the latest June 2023 update, in addition to fall detection.. This sentence can be rewritten as: In order to provide a more complete health monitoring service, the product is also able to monitor the user's blood oxygen by enabling the SpO2 sensor level.
