  • Google has filed a patent for fall detection via smart home devices using a radar system.
  • The feature would notify an emergency contact or emergency services in the event of a fall.
  • This suggests that the radar-equipped second-generation Nest Hub could gain fall detection support.

Fall detection is one of the most important features on smartwatches and trackers today, allowing elderly people and other users to get help in the event that they’ve fallen and can’t get back up. Now, it looks like Google could be thinking about bringing this feature to its Nest Hub line.

The company filed a patent with the US Patent and Trademark Office (USPTO) titled ‘Privacy-preserving radar-based fall monitoring.” This patent describes the use of a stationary “smart home device” or “home assistant device” that uses radar waves to detect whether a nearby person has fallen.
