Collaborative exploration of 360 videos with contemporary interfaces is challenging because collaborators do not have awareness of one another's viewing activities. Tourgether360 enhances social exploration of 360° tour videos using a pseudo-spatial navigation technique that provides both an overhead "context" view of the environment as a minimap, as well as a shared pseudo-3D environment for exploring the video. Collaborators are embodied as avatars along a track depending on their position in the video timeline and can point and synchronize their playback. We evaluated the Tourgether360 concept through two studies: first, a comparative study with a simplified version of Tourgether360 with collaborator embodiments and a minimap versus a conventional interface; second, an exploratory study where we studied how collaborators used Tourgether360 to navigate and explore 360° environments together. We found that participants adopted the Tourgether360 approach with ease and enjoyed the shared social aspects of the experience. Participants reported finding the experience similar to an interactive social video game.
