Apple wants to make it easier for multiple Vision Pro uses to share an extended reality environment. The company has been granted a patent for a “Gaze-based Copresence System.”
About the patent
This patent relates generally to image processing. More particularly, but not by way of limitation, it involves techniques and systems for improving power and data usage in transmitting avatar data.
In the patent Apple notes that some devices are capable of generating and presenting extended reality (XR) environments. An XR environment may include a wholly or partially simulated environment that people sense and/or interact with via an electronic system. In XR, a subset of a person’s physical motions, or representations thereof, are tracked, and, in response, one or more characteristics of one or more virtual objects simulated in the XR environment are adjusted in a manner that comports with at least one law of physics.
Some XR environments allow multiple users to interact with each other within the XR environment. However, transmitting such avatar data can be computationally expensive. Apple wants to change this.
Summary of the patent
Here’s Apple’s abstract of the patent: “A technique for transmitting data in a copresence environment includes initiating a virtual communication session between a local device and remote devices in a shared copresence environment, where each of the plurality of sending devices are transmitting a sending quality data stream in the virtual communication session.
“A region of interest for the local device is determined that includes a portion of the copresence environment. The local device subscribes to a first quality data stream for the remote devices represented in the region of interest, and a second quality data stream for the remote devices not represented in the region of interest.”
