Virtual Replicas for Remote Assistance in Virtual and Augmented Reality
summary
System builds virtual replicas of tracked physical parts and lets a remote expert manipulate them in stereoscopic VR/AR using an OptiTrack 6DOF setup and a 6DOF input device. Two techniques: Point 3D (specify contact points with a 3D pointer and rubber‑band cues) and Demo 3D (directly move a replica, supported by constraints that snap poses). A 22‑participant study over 144 target poses compares to a 2D tablet sketch baseline and finds Demo 3D fastest and most preferred; Point 3D helps trained experts.
