This project explores the combination of Spatial Augmented Reality and Virtual Reality, two technologies with complementary characteristics that evolved separately in the past.
Spatial Augmented Reality (SAR) augments the environment using projectors or screens, without the need of user instrumentation. By keeping a a single unified frame of reference, it supports social interaction and natural perception of the space, but the augmentation is limited by physical constraints (e.g., it requires a surface to display information). Immersive head mounted displays on the other hand are not limited by the physical properties of the environment, yet they isolate the user from their environment.
By providing a unified frame of reference for both SAR and immersive displays, the users can select the visualization that is best suited for a given task. This enables both asymmetric collaboration between users, and back-and-forths for a single user.
