Apple is researching new types of user interaction methods, including a system that could trigger certain features if it detects a user is present — including marking a notification as read.

In a patent application published Thursday by the U.S. Patent and Trademark Office, Apple outlines a system that could detect whether a user is in its immediate vicinity. It also includes detection of a user’s gaze for more granular UX capabilities, opening up a range of control possibilities for devices like the iPhone, Apple TV, Mac, or HomePod.
