Abstract: Systems and methods for using positions of detected, real object boundaries to enable user interaction with a virtual object are disclosed. A system can include one or more sensors or trackers configured to detect boundaries of a transparent, real object within a three-dimensional coordinate system. A computing device configured to track positions of the detected boundaries of the real object within the three-dimensional coordinate system. The computing device may also track a position of a virtual object within the three-dimensional coordinate system. The computing device may determine whether the position of the virtual object is within the positions of the detected boundaries of the real object. The computing device may also enable user interaction with the virtual object via user interface and receive input for interacting with the virtual object in response to determining that the position of the virtual object is within the positions of the detected boundaries.
