A user wearing a headset looks at a mobile robot in a room. From the user’s eyes, a viewing cone spans the robot from top to bottom. Point-based “splats” inside the cone are colored red, showing what is visible, and those outside are gray, for discard. As the headset moves or the robot moves, the cone adapts to always cover the robot. A second cone is used for the arm, and it grows and shrinks to cover the arm as it expands. Feathering is used to blend the cone with the background, acting like an invisibility cloak.

On the left is a desk; to the right, a far shelf where a small potted plant sits. The user, seated on a couch, reaches out as if toward the plant. A dashed line from the hand to the plant suggests the object is aimed at. With a pinch and arm retraction, a virtual duplicate of the plant moves closer while the physical plant disappears. The user then places the duplicate on a surface, such as the desk by a window, where it lands, and a countdown begins. A hidden robot then moves the physical plant to where the virtual twin has been placed, fulfilling the reality promise.

a bee-like virtual character flies toward a Pringles can on a table to the right of the scene. As it arrives, the real can is visually masked, and a virtual duplicate appears. The bee carries the virtual can along a curving path toward the left. Near the end, the bee heads straight to a drop point; at the same moment, the physical can arrives there (moved by a hidden mobile robot). The virtual and physical coincide, the bee exists, and the can seems to materialize.
