MR Assembly Guidance System for an Automotive Manufacturer

Basic AR overlays a 2D digital layer onto a camera view suitable for simple information display. Mixed reality (MR) uses spatial computing to anchor persistent 3D digital objects into the physical environment that understand and interact with it digital instructions that rest on the actual component, stay aligned as the worker moves, and respond to the physical context. HoloLens 2 is the leading MR device for industrial applications.

The system connects to SAP production orders via a middleware API that reads the current work order for each assembly station. When specifications change in SAP, the HoloLens guidance updates automatically no manual content updates required. Completion confirmations and quality check data are written back to the SAP work order, maintaining a complete digital audit trail.

ROI comes from three sources: defect reduction (fewer rework and warranty costs), assembly time efficiency (experienced workers no longer referencing paper documentation), and onboarding acceleration (new staff reach full productivity significantly faster). For this engagement, the defect rate reduction alone recovered the full project cost within the first quarter of deployment.
