Google Nest introduces ultrasonic features: based on whether someone nearby highlights screen content

Smart Display is ideal for displaying information such as weather, schedules, recipes, and time. But unlike traditional clocks, the information displayed on the smart screen is used close and privately, making it often difficult to see what is displayed on the screen over a longer distance. To that end, Google has developed a new system that uses ultrasonic sensors to determine if there is a person nearby and changes what’s on the screen.

When someone approaches the screen, the Nest Hub device automatically expands the weather card and displays the touch controls. As you go further, Nest Hubs will increase font size and graphics to make timers, weather reports, and commute maps easier to read, and hide touch controls.

Like Hub Max, Nest Hub can proactively display notifications. But because it doesn’t have a camera configured for facial recognition, it will only display publicly available information, not private information. Google tells us that ultrasonic technology is now being rolled out on Hub and Hub Max.
