Abstract: In one aspect, a first sequence of patterns of light symbols that spatio-temporally encode two-dimensional position information in a first projection plane is projected onto a scene. A second sequence of patterns of light symbols that spatio-temporally encode two-dimensional position information in a second projection plane is projected onto the scene. Light patterns corresponding to the first and second sequences of patterns of light symbols reflected from the scene are captured at a capture plane. Captured light symbol sequence codes are determined from the captured light patterns. A correspondence mapping of the first projector plane and the second projector plane with respect to a reference coordinate system is generated based at least in part on correspondence between the captured light symbol sequence codes and the first and second sequences of light symbol patterns.

A plurality of data object arrangement schemes are provided for arranging corresponding represented images of the data objects within the three-dimensional environment dependent on a selected one of the schemes. The data objects are then automatically arranged within the three-dimensional environment according to the selected schemes. Schemes can be user selected such that by selecting a new scheme, the objects are rearranged according to the newly selected scheme. The environment is partitioned into three-dimensional areas and representative images of the data objects are arranged within the partitioned environment such that representative images of related groups of data objects with respect to the selected scheme are displayed within the same areas.

Abstract: Systems and methods of multiframe correspondence estimation are described. Light patterns reflected from the scene are captured at one or more capture planes. In one aspect, a sequence of patterns of light symbols that temporally encode two-dimensional position information in a projection plane with unique light symbol sequence codes is projected onto a scene. A correspondence mapping between multipixel regions in the capture plane and corresponding regions in the projection plane is computed based at least in part on correspondence between light symbol sequence codes captured at the capture plane and light symbol sequence codes projected from the projection plane. In another aspect, the patterns consist of a single plane of light that is swept across the scene. Correspondence is determined based at least in part on exploiting the epipolar constraint associated with any pair of cameras.

According to the apparatus and method, the database of objects is represented by a hierarchical tree derived from the object metadata. The tree includes parent nodes, their associated child nodes, and data object nodes, where every node has an associated weight. A predetermined parent node is pre-assigned an area corresponding to the undivided graphical environment. Then, for each parent node having at least two associated child nodes in the tree, the area is recursively divided into a plurality of areas corresponding to each of the associated child nodes such that the areas are proportional to the child node weights.

According to the apparatus and method an environment is divided into areas bounded by partitions, and groups of representative images are distributed and displayed upon these partitions. In general, distribution of the representative images is achieved by determining weight factors for each partition bounding a given area and determining weight factors for representative images that are to be displayed within the areas upon the partitions and then distributing the images dependent on the comparison of the image weight factors to partition weight factors.

Abstract: A user interface and method for interacting with a three-dimensional graphical environment is determined. Multiple viewing perspectives are provided to the user to allow the user to view and navigate through the environment at approximately eye level or “fly over” and view the environment from an overhead view. Labels corresponding to partitioned areas rotate to adjust to the changing perspective of the user and area color coding adjusts hierarchically dependent on the user's perspective. Partitions and the ceiling of the environment have variable translucency/transparency so as to provide the user with forward viewing capability of the environment and read labels in other areas. The interface controls the movement of the user's in a natural manner and movement is tracked to provide the user with a history of the user's previous navigation path. Addition information views are provided by the interface relating to different objects within the interface.
