Method for Operating a Server-Based Master Database for a Multi-User Collaborative Augmented Reality System

Smart overview of the Invention

The patent application describes a system for operating a server-based master database to facilitate a multi-user collaborative augmented reality (AR) experience. This system allows multiple users, each equipped with their own AR device, to engage in shared AR sessions at the same physical location. The system uses physical models, referred to as anchors, that are recognizable by the AR devices' cameras and image processing modules. These sessions can be managed by initiators who control participant access and invitations.

Field and Background

The invention pertains to augmented reality systems, particularly those enabling shared AR experiences based on real-world locations. Traditional AR toys and games often use anchors like jigsaw puzzles or preprinted cards to trigger digital augmentations. However, these systems typically do not allow multiple players with individual devices to view the same anchors and interact within a coherent AR environment. Moreover, existing systems struggle with ambiguity when identical anchors are present near each other.

Addressing Limitations

The proposed system addresses these limitations by allowing several players to interact using their own devices while sharing a consistent AR world. It resolves ambiguities arising from similar anchors through server communication, where each device registers recognized anchors along with its location data. This approach ensures that actions taken by one player do not inadvertently affect another's gameplay. Additionally, the system supports linking distinct sites into a unified AR experience.

System Functionality

Each user's AR device is connected wirelessly to a central server that manages session data and anchor registration. When a player initiates a session, their device registers recognized anchors with the server, which uses location data to manage session coherence. If another player attempts to join or start a new session using similar anchors, the server verifies their intent and manages potential conflicts by suggesting modifications to distinguish the anchors.

User Experience

Once players join a common session, their devices display coherent augmented reality views that reflect the same virtual elements, despite different perspectives. For instance, if two players observe an anchor from different angles, their devices will augment the view consistently with digital elements like animated characters or effects. This ensures an immersive and synchronized experience across multiple users' devices.
