VR+4CAD

Summary

VR+4CAD addresses several barriers limiting the adoption of virtual reality in manufacturing and design: incomplete interoperability between VR and CAD workflows, the friction involved in entering and interacting with virtual environments, and the limited feedback available for subsequent design analysis.

The project investigates how CAD-authored designs can be automatically converted and adapted for direct human interaction in VR. An experimental markerless motion capture system allows users to interact naturally with virtual prototypes without wearing dedicated tracking devices.

Motion data collected during each session is analyzed using activity recognition techniques to generate implicit feedback about user behavior and interaction. This information is combined with explicit user feedback and returned to the CAD operator, supporting the next iteration of the design process.
