Extended Reality (VR/AR/MR) is revolutionizing prototyping by enabling real-time 3D visualization, collaborative iteration, and user testing—all before physical production begins. From automotive design to consumer electronics, XR slashes costs, accelerates timelines, and unlocks creative possibilities.
Key Applications of XR Prototyping
1. Conceptual Design & 3D Modeling
- VR Sketching
- Gravity Sketch: Create organic shapes with hand tracking (used by Ford, Nike)
- Adobe Substance 3D Modeler: Sculpt photorealistic materials in VR
- AR Overlay Drafting
- Shapr3D AR: Refine CAD models over real-world contexts via iPad
2. Engineering & Functional Testing
- Virtual Assembly
- Taqtile Manifest: Validate part fit/clearance with HoloLens-guided disassembly
- Siemens NX VR: Test ergonomics in 1:1 scale
- Physics Simulations
- Unreal Engine Chaos Physics: Drop, crush, or stress-test prototypes in VR
3. User Experience (UX) Validation
- Human-Centered Testing
- Varjo XR-4: Eye-tracking reveals how users interact with virtual products
- Haptic Feedback: SenseGlove simulates button resistance/weight
- A/B Design Comparisons
- Mozilla Hubs: Stakeholders vote on VR prototype variants
4. Manufacturing Prep
- Digital Twin Factories
- NVIDIA Omniverse: Simulate production lines with robotic arms
- AR Work Instructions
- Scope AR: Guide technicians through assembly pre-production
