HTC announced a new variant of its high-end Vive Pro virtual reality headset today at CES that comes with native, built-in eye tracking. The device is called the Vive Pro Eye, and it promises to bring higher-quality VR experiences, thanks to a technique called “foveated rendering” that focuses only on what the human eye is looking at in a virtual scene and reduces the image quality of objects on the periphery.

In addition to higher-quality images, eye tracking in VR also opens up new possibilities for new forms of hands-free interaction in VR and accessibility options for those who don’t have the ability to use full motion controllers. Imagine being able to quickly open menus, search a library of titles or even the open web, and selecting objects in a virtual environment by just focusing your line of sight.
