Systems, methods, and computer-readable media for managing collaboration on a virtual work of art

This invention describes a way for multiple people to collaborate on a virtual artwork using their own electronic devices, like tablets or phones. Instead of sending entire images back and forth, which can be slow, the system shares only the specific drawing actions or commands each person makes. This reduces delays, making the collaboration feel more immediate. The claims specifically focus on a touch-sensitive device receiving an instruction to show a user interface from another device already displaying the artwork, allowing the user to draw on it with their finger.
