Figure 1: Photo-edited view of collaborators using our Wall+AR prototype displaying image cards, a setup similar to our study. The wall display is seen on the right, and shared virtual surfaces on the left and center of the image. The user on the right is looking at their personal space that moves with them, and is not visible to others. The virtual surfaces and personal space are shown only in Augmented Reality, while the wall is a physical display in the room.
