VR THOR – Virtual Reality Training with Hotstick on Operations Risks

Abstract: In this work we do present an interactive and collaborative 3D object manipulation system using off the shelf mobile devices coupled with Augmented Reality (AR) technology that allows multiple users to collaborate concurrently on a scene. Each user interested in participating in this collaboration uses both a mobile device running android and a desktop (or laptop) working in tandem.

The 3D scene was visualized by the user in the desktop system. Scene viewpoint changes and object manipulations were performed using a mobile device through the AR. The system leverages user’s knowledge of common tasks performed on current mobile devices such as pinching for zooming in and out; swiping with one or two fingers for object rotation and press-andhold for 2 seconds for object translation.

As you will see in this video, we built a prototype system (in a maze style) and performed an informal user study with three experienced VR researchers. Users had to carry a 3D cube through three square rings along the maze. In resume, we diagnosed that working in a collaborative way (users A and B) was better and easier than individual one (user C). We register more than 2 minutes late for the individual experience comparing to the teamwork. It may happen because the two player team shared information, functions and had a multi-perspective view during the task.
