According to the United States Trademark and Patent Office (USPTO) public list, Apple recently obtained a technology patent involving the collaborative creation of virtual works on the iPad, No. US 11625136 B2.
The patent, titled “System, Method, and Computer Readable Media for Managing Virtual Work Collaboration on Multiple Devices,” allows one or more users to collaborate on the creation of virtual artworks on two or more electronic devices.
Attached is the abstract of Apple’s patent as follows:
"This patent provides systems, methods, and computer-readable media for managing the collaboration of virtual artworks among multiple electronic devices.
A first graphical display system of a first device may respond to user information and generate an input command and share the input command with a second graphical display system of a second device.
The first graphic display system may process the shared input command and the canvas of the first device and the second device generates pixel array data. By sharing input commands instead of pixel array data, system latency can be reduced.
Although operating on the same artwork, the user interface and graphics processing capabilities of each device may differ, thus providing greater expressiveness to the user."
