The project investigates how collaborative tasks can be enhanced in AR environments. The intern will develop three approaches to present shared information in a co-located AR setting and conduct usability studies comparing these approaches. The first approach will present information in the same location and same orientation to the collaborators, the second will present the information in the same location but virtually oriented to both collaborators and the third approach will allow collaborators to place information in different locations while maintaining virtual ties between the displays for the two users. The most promising approach will be integrated in VizworX’ AR tools.
