Google has begun deploying a new feature for Nest Hub and Hub Max, which uses ultrasound presence detection technology to detect the presence of people and automatically customize the user interface based on current conditions.
Already implemented on the Nest Mini and Nest Wifi satellites, ultrasound sensing uses Nest Hub’s and Hub Max’s built-in speakers to emit high-frequency sounds, and then listens for feedback with their microphones. (Google told Engadget that frequencies should not disturb your pets, who usually have more sensitive hearing than people.)
With ultrasound detection, new Nest devices can detect people up to five meters and customize the items displayed. Ultrasonic detection does not have facial recognition, so it can not customize the experience, but it can for example automatically increase the font size when you move away from it or expose the touch controls to the approach. This feature must be available on the Nest Hub, Nest Hub Max, Nest Mini, and Nest WiFi Point.
In a concrete example shared on Reddit, an original Google Home Hub owner noticed that the device was suddenly able to detect when it was being scanned. “I had just set a timer because I had food in the oven and every time I looked at my phone, the timer went into” full screen mode, “but when I turned my head to look at the main hub Google’s time was minimal. ”
This update may not be the most revolutionary for Hub Max, which comes with a built-in camera that is already able to recognize who is using the device and respond with features intended for specific members of the device. 39, a household. However, the addition of ultrasound detection is particularly noteworthy for the Home Hub because it does not have a camera.
In separate but similar information, the microphone inside the Nest Guard keyboard, which is part of the Nest Secure alarm system, can now detect the sound of broken glass. You can activate the new feature via the Nest app by going on Settings> Security> Security Levels> Away and Protection or Home and Protection> Detecting Glass Breakage.
