Apple is looking into ways to improve the recording abilities of future Vision Pros. The tech giant has been granted a patent for a “Head-Mounted Electronic Device with Display Recording Capability.”
About the patent
In the patent Apple notes that electronic devices such as head-mounted devices can include hardware and software subsystems for performing gaze tracking, hands tracking, and head pose tracking on a user. Such electronic device can also include a graphics rendering module for generating virtual content that is presented on a display of the electronic device. The electronic device can also include a compositor that adjusts the virtual content based on the user tracking information prior to displaying the virtual content. The adjusted virtual content can then be output on the display to the user.
However, Apple notes that it’s challenging to record the content that is displayed to the user. The displayed content may be output at a first frame rate. The electronic device may record the content, however, at a second frame rate that is different than the first frame rate of the display.
In such scenarios, the displayed content can’t simply be copied as the recorded content. Apple wants to overcome such limitations with future Vision Pros — or perhaps with updates to visionOS.
Summary of the patent
Here’s Apple’s abstract of the patent: “A head-mounted device is provided that includes a variety of subsystems for generating extended reality content, displaying the extended reality content, and recording the extended reality content. The device can include a graphics rendering pipeline configured to render virtual content, tracking sensors configured to obtain user tracking information, a virtual content compositor configured to composite virtual frames based on the virtual content and the user tracking information, cameras configured to capture a video feed, a media merging compositor configured to overlay the composited virtual frames and the video feed to output merged video frames having a first frame rate for display, and a recording pipeline configured to record content having a second frame rate different than the first frame rate. The recording pipeline can record content exhibiting a higher quality than the content being displayed. A portion of the recorded content containing sensitive information can optionally be blurred.”
