Virtual Reality devices are available with different resolutions and fields of view. Users can simultaneously interact within environments on head mounted displays, cell phones, tablets, and PowerWalls. Sharing scenes across devices requires solutions that smoothly synchronize shared navigation, minimize jitter and avoid visual confusion. In this paper we present a system that allows a single user to remotely guide many remote users in a virtual environment. A variety of mixed device environments are supported. Techniques are implemented to minimize jitter and synchronize views

360◦photogrammetry captures the surrounding light from a central point. To process and transmit these types ofimages over the network to the end user, the most common approach is to project them onto a 2D image usingthe equirectangular projection to generate a 360◦image. However, this projection introduces redundancy into theimage, increasing storage and transmission requirements. To address this problem, the standard approach is touse compression algorithms, such as JPEG or PNG, but they do not take full advantage of the visual redundancyproduced by the equirectangular projection. In this study of the 360SP dataset (a collection of Google StreetView images), we analyze the redundancy in equirectangular images and show how it is structured across theimage. Outcomes from our study will support the developing of spherical compression algorithms, improvingthe immersive experience of Virtual Reality users by reducing loading times and increasing the perceptual imagequality.
