The tech giant has revealed the upcoming smartphone will benefit from Motion Sense, which means things like turning an alarm on, changing a song and silencing a call will be possible without any tapping or talking to the device, thanks to the all-new Soli radar chip.
It works by simply waving your hand at the device.
Pixel product manager Brandon Barbello said in a blog post:"Pixel 4 will be the first device with Soli, powering our new motion sense features to allow you to skip songs, snooze alarms, and silence phone calls, just by waving your hand.
These capabilities are just the start, and just as Pixels get better over time, motion sense will evolve as well."
The phone will also have face unlocking like Apple's FaceID.
The front of the smartphone features a top bezel, which has been heavily reported is to make way for a Soli sensor.
It's also been revealed it will feature a single front-facing camera.
The recent reveals come after it was reported that Night Sight will be one of the Pixel phone's main camera modes.
Google has revamped its list of modes and swapped out panoramas in favour of its feature focused on taking photos in bad lighting.
According to 9to5Google, the leaked Android Q beta build revealed the switch, which sees Night Sight listed as the mode on the far left.
If the format remains the same, the modes listed in the main viewfinder will be Night Sight, Portrait, Camera and Video.
The 'more' tab will include Panorama, alongside Photo Sphere, Photo Booth, Slow Motion, Time Lapse, Playground, Lens and Settings.
Meanwhile, the same update appears to show that the ability to adjust white balance in photos has been removed.
While it could be a bug in the unreleased beta software, the temperature icon - which allows users to choose from different preset options - doesn't seem to be there anymore.
