Abstract: 
This paper presents an AR videoconferencing approach merging two remote rooms into a shared workspace. Such bilateral {AR} telepresence inherently suffers from breaks in immersion stemming from the different physical layouts of participating spaces. As a remedy, we develop an automatic alignment scheme which ensures that participants share a maximum of common features in their physical surroundings. The system optimizes alignment with regard to initial user position, free shared floor space, camera positioning and other factors. Thus we can reduce discrepancies between different room and furniture layouts without actually modifying the rooms themselves. A description and discussion of our alignment scheme is given along with an exemplary implementation on real-world datasets.
