🧠 Industrial AR Fundamentals

🎯 AR for the Enterprise

Industrial AR (Enterprise AR) applies augmented reality to manufacturing, logistics, field service, and maintenance. Unlike consumer AR, industrial AR focuses on productivity, safety, quality, and ROI. It overlays work instructions, remote expertise, and digital twins onto real equipment and processes.

Why Industrial AR Matters

Productivity: 30-50% faster task completion. Error reduction: 50-90% fewer mistakes. Training: Faster onboarding, better retention. Remote expertise: Experts see what field techs see. Safety: Hands-free, contextual warnings. Cost savings: Less travel, less downtime, less waste. Market: $70B+ by 2030.

📞 Remote Assistance

🎯 See what I see

Remote assistance enables a remote expert to see the field technician's view and annotate it in real-time. The technician wears AR glasses; the expert uses a computer to draw arrows, circles, and instructions that appear in the technician's view.

Remote Assistance Features

Live video: Expert sees technician's camera. Annotations: Draw arrows, circles, text. Freeze frame: Pause on a frame to annotate. File sharing: Send documents, diagrams. Recording: Save session for training. Multi-party: Multiple experts join.

💰 ROI & Business Case

🎯 Making the case for AR

Industrial AR must demonstrate ROI: time savings, error reduction, training acceleration, travel reduction, and downtime avoidance. Typical payback: 6-18 months.

ROI Drivers

Productivity: 30-50% faster task completion. Quality: 50-90% fewer errors. Training: 40% faster onboarding. Travel: 50-80% fewer expert trips. Downtime: 20-40% less unplanned downtime. Safety: Fewer incidents, lower insurance.
