Multi-User Support

AR2 introduces real-time collaboration features with synchronized spatial anchors and persistent object placement across multiple devices.

Key Additions:

Peer-to-peer session synchronization
Conflict resolution strategies
Latency compensation algorithms
Secure session management

Advanced SLAM

Improved simultaneous localization and mapping with dynamic environment adaptation for better object occlusion and spatial mapping accuracy.

Performance Comparison:

AR1 72% Accuracy AR2 89% Accuracy

Audio Spatialization

Environment-cognizant audio processing that spatializes sounds based on 3D object positions and listener perspective.

Audio engines now support HRTF-based spatial rendering for immersive experiences.

Optimized Rendering

Frame rate improvements through asynchronous compute and object culling based on viewer position.

Performance Gains:

Mobile Devices +33% FPS

Desktop VR +42% FPS

Battery Usage -18%

Multi-User AR Example (AR2)


// Create shared AR session
const session = new ARSession({
    requiredFeatures: ['collaboration', 'advancedSLAM'],
    maxUsers: 4,
    sessionID: 'multi-user-demo-2025'
});

// Add spatial object to shared view
const marker = new SharedARObject({
    type: 'collidable',
    position: {x: 1.5, y: 0.5, z: 2.0},
    metadata: {owner: 'USER-A', persistent: true}
});

// Handle user join events
session.on('userJoined', (userData) => {
    console.log(`${userData.name} has entered the shared space`);
    createAvatar(userData);
});

// Synchronized spatial audio
const sounds = loadAudioObjects([
    {
        position: {x: 3.5, y: 0, z: -1},
        gain: 0.8,
        distanceModel: 'exponential'
    }
]);
