About

What is VR+4CAD?

The goal of VR+4CAD is to address a series of recurring limitations that prevent a wider adoption of Virtual Reality (VR) by the manufacturing and design industries.

VR+4CAD aims for CAD-authored design to be automatically converted and adapted for human interaction within a virtual environment. Interaction is made more immediate by means of an experimental, markerless motion capture system. Its acquired data is further analyzed via Human Activity Recognition (HAR) techniques and transformed into implicit feedback. Both explicit and implicit feedback are merged and sent back to the CAD operator for the next design iteration.
