Google is introducing an innovation for the Nest Hub (Google Home), also for German users, with which the voice assistant automatically detects users in the immediate vicinity and executes functions. Ultrasonic. Google's primary goal is to help users struggling with a visual impairment. Google had announced the expansion of the ultrasound functions, and first readers informed us about new sliders in their Nest Hub settings.

Google introduces ultrasound capabilities for voice assistants

We wanted to create a better experience for people with visual impairment. That's why our goal is to enable more people to see our display from any distance in a room without affecting the useful information that the nearby display can show. The result is what we call an ultrasonic sensor.

Ultrasound for timers, reminders, and more

The ultrasonic measurement already works for timers, commuting times and weather. In the coming week, reminders, appointments, and warnings will also appear on your devices as you approach the display. Because this uses low-resolution sensing technology, the ultrasound sensing is done entirely on the device and can only capture large-scale movements (like a moving person) without realizing who the person is.

Activate or deactivate the ultrasound detection:

  1. Open the Google Home app Google Home app.
  2. Call up the device settings.
  3. Scroll down to the Ultrasonic Detection setting.
  4. Move the slider to on or off.
