Abstract: Users can intuitively and non-obstructively obtain awareness of fellow collaborator views and/or statuses in an augmented reality environment. An interaction is detected between a first and second HMD. The detected interaction can cause the first HMD to request state information associated with the second HMD. The second HMD can process the request to generate a set of visual data as a response to the request. The second HMD can communicate the set of visual data to the first HMD, so that the first HMD can render the received set of visual data to be displayed concurrently with its own augmented view. Additional computer-generated object(s) can be positioned in accordance with a real-world or virtualized position of the second HMD, such that the now-visible state information associated with the second HMD does not obstruct a view of the first or second HMD's user.

Abstract: Various systems and techniques for intuitively and non-obstructively obtaining awareness of fellow collaborator views and/or statuses in an augmented reality environment are disclosed.

Abstract: A mechanism is provided for exploring three dimensional environments such as those generated from X-ray and tomography scans, in such a way as to “see round” obstacles to an article of interest, without degrading the overall context of an article of interest in terms of it position in relationship to other articles, and to the viewpoint of the user. This is achieved by defining a light guide curve leading to the user's viewpoint, with respect to which ray tracing is performed to define the image displayed to the user whereby rays passing within a predetermined distance of the light guide curve at a relative angle within a predetermined range thereto are deviated so as to conform therewith to a degree proportional to its distance therefrom.

Abstract: In a crowded representation of a virtual three dimensional space defined in terms of voxels, an object of interest will often be occluded by one or more objects of varying densities between the virtual camera defining the user's point of view, and the object of interest. To automatically identify an optimal camera position, an number of candidate positions are considered, for example situated at the vertices of a regular polyhedron centred on the object of interest. For each of these candidate positions, a ray is cast towards the object of interest, and the occlusion for each intervening voxel is determined as the product of that voxel's density, and a density transfer function. The virtual camera position corresponding to the least occluded path is then selected as the new point of view.

Abstract: Objects in a voxel based computer generated three dimensional environment are identified by traversing adjacent voxels meeting a predetermined criterion with respect to a scalar metadata value associated with each voxel, such as opacity or density. These adjacent voxels may be explored in accordance with a tree-crawling algorithm such as a breadth first or depth first algorithm. Once all adjacent cells meeting the criterion are identified, these are determined to represent a discrete object, and displayed as such. The starting point for the traversing process may be the voxel closest to a virtual camera position along the line of sight of that virtual camera meeting the criterion.

Abstract: In various embodiments, computerized methods and systems for syndicating direct and indirect interactions with objects in a computer-mediated environment to facilitate precise interactions with the objects in the computer-mediated environment are provided. The system detects a direct interaction with an object in the computer-mediated reality environment. The direct interaction may be a natural or hypernatural interaction. Subsequently, the system may determine various options of indirect interaction with the object related to the direct interaction. The indirect interaction may be generated by a controller. Upon receiving an indirect interaction, the system may modify the object based on the syndication of the direct interaction and the indirect interaction.

Abstract: A method of defining a path model from a set of realistic paths is provided, where each path in the set of realistic paths is expanded on piece-wise polynomial basis, and a respective centroid function and sequence of eigenfunctions calculated for each expanded representation. A set of principle paths representing the major variation of this set of paths is obtained describing the variations of the set of realistic paths with respect to the centroid. The path model thus comprises a linear combination of said principle paths. The path model may be used as the basis for the generation of new curves having similar characteristics to the original set of realistic paths.
