Apple is building a mixed reality headset that tracks users' facial expressions
Apple has filed a patent for a mixed reality headset that includes a range of sensors designed to track users' facial expressions.
As Variety reports, the patent is for a device called a Display System Having Sensors. It consists of a headset that "provides virtual 3D views of a user's environment augmented with virtual content."
The device includes space for a range of different sensors, each designed to monitor different user activity.
"Head pose sensors" track the location and orientation of the user's head, while separate sensors track eyebrow movements and mouth and jaw activity.
The latter two sensors are thought to be designed to help the device understand a user's facial expression.
The sensors are all built into a head-mounted display that not only displays content for the wearer, but also captures and interprets data about their surroundings.
Apple has long been rumoured to be working on a mixed reality device. It is thought that the company's first headset product will be released next year.
