Projectors and depth cameras for deviceless augmented reality and interaction
First Claim
1. A multi-dimensional modeling system, comprising:
- an arrangement of depth-sensing cameras that sense objects in a physical space and output sensed information;
an arrangement of projectors that impose projections relative to the physical space, with the projections interrelated such that objects in at least two projections are cross-referenced to establish connectivity in the physical space,at least a portion of the connectivity computed by constructing tables that index connecting components from one view to another view;
a mapping component that maps portions of the sensed information to the projections to create mapping information; and
a modeling component that creates a multi-dimensional model based on the mapping information, the multi-dimensional model describing a relationship between output of the cameras and the projectors for virtual interaction between a user and an object in the physical space.

Abstract
Architecture that combines multiple depth cameras and multiple projectors to cover a specified space (e.g., a room). The cameras and projectors are calibrated, allowing the development of a multi-dimensional (e.g., 3D) model of the objects in the space, as well as the ability to project graphics in a controlled fashion on the same objects. The architecture incorporates the depth data from all depth cameras, as well as color information, into a unified multi-dimensional model in combination with calibrated projectors. In order to provide visual continuity when transferring objects between different locations in the space, the user'"'"'s body can provide a canvas on which to project this interaction. As the user moves body parts in the space, without any other object, the body parts can serve as temporary “screens” for “in-transit” data.
