2. Core Functionality

A. Real-Time Annotation Tools

// Unity-based spatial annotation
public class ARAnnotation : MonoBehaviour
{
    void Update()
    {
        if (airTapTriggered)
        {
            var anchor = new SpatialAnchor(
                gazeHit.point,
                voiceNote,
                DateTime.UtcNow
            );

            CloudService.UploadAnchor(expertSessionID, anchor);
        }
    }
}

B. Multi-Sensor Fusion

Data Stream	Processing Method	Latency
Live Video	H.265 encoding @ 30fps	<300ms
Thermal Imaging	FLIR SDK integration	150ms

5. ROI Calculation

Automotive Assembly Case Study:

• 87% reduction in machine downtime
• 65% faster problem resolution
• $420k/year savings per production line
• 3.2x more issues resolved remotely

Key Metrics:

def calculate_roi(implementation_cost, annual_savings):
    payback_period = implementation_cost / annual_savings
    yearly_benefit = annual_savings * 3  # 3-year projection
    return {
        'payback_months': round(payback_period * 12, 1),
        '3y_roi': f"{((yearly_benefit - implementation_cost)/implementation_cost)*100:.0f}%"
    }

6. Emerging Technologies

• Haptic Guidance: Ultrasonic feedback for tool placement
• AI Co-Pilot: Computer vision with live troubleshooting
• Digital Twin Integration: Overlay real-time IoT data
• Neural Compression: 80% bandwidth reduction for 3D data

Implementation Checklist:
✔ Conduct network readiness assessment
✔ Define escalation protocols (XR → phone → onsite)
✔ Train super-users for internal support
✔ Establish annotation standards (colors/icons)
✔ Implement session recording for audit/QA
