A mixed-reality headset Apple is developing will be equipped with more than a dozen cameras for tracking hand movements and showing video of the real world to people wearing it, along with ultra-high-resolution 8K displays and advanced technology for eye tracking, according to a person with direct knowledge of the device.

Those are among a bevy of features Apple is planning for the headset, a device that could represent one of the company’s most ambitious efforts to build a new technology platform. The Information viewed internal Apple images of a late-stage prototype from last year, which show a sleek, curved visor attached to the face by a mesh material and swappable headbands. An artist’s rendering based on the images of the headset and created by The Information appears below.
