20100001998 | Apparatus and method for determining an absolute pose of a manipulated object in a real three-dimensional environment with invariant features - An apparatus and method for optically inferring an absolute pose of a manipulated object in a real three-dimensional environment from on-board the object with the aid of an on-board optical measuring arrangement. At least one invariant feature located in the environment is used by the arrangement for inferring the absolute pose. The inferred absolute pose is expressed with absolute pose data (φ,θ,ψ,x,y,z) that represents Euler rotated object coordinates expressed in world coordinates (X | 01-07-2010 |
20100013860 | Computer interface employing a manipulated object with absolute pose detection component and a display - A system that has a remote control, e.g., a wand, equipped with a relative motion sensor that outputs data indicative of a change in position of the wand. The system also has one or more light sources and a photodetector that detects their light and outputs data indicative of the detected light. The system uses one or more controllers to determine the absolute position of the wand based on the data output by the relative motion sensor and by the photodetector. The data enables determination of the absolute pose of the wand, which includes the absolute position of a reference point chosen on the wand and the absolute orientation of the wand. To properly express the absolute parameters of position and/or orientation of the wand a reference location is chosen with respect to which the calculations are performed. The system is coupled to a display that shows an image defined by a first and second orthogonal axes such as two axes belonging to world coordinates (X | 01-21-2010 |

20120038549 | Deriving input from six degrees of freedom interfaces - The present invention relates to interfaces and methods for producing input for software applications based on the absolute pose of an item manipulated or worn by a user in a three-dimensional environment. Absolute pose in the sense of the present invention means both the position and the orientation of the item as described in a stable frame defined in that three-dimensional environment. The invention describes how to recover the absolute pose with optical hardware and methods, and how to map at least one of the recovered absolute pose parameters to the three translational and three rotational degrees of freedom available to the item to generate useful input. The applications that can most benefit from the interfaces and methods of the invention involve 3D virtual spaces including augmented reality and mixed reality environments. | 02-16-2012 |
20120209984 | Overlay Network - Methods, apparatus and systems, including computer program products, implementing and using techniques for providing a scalable and elastic two-level overlay computer network. A host network is provided. The host network includes a system of interconnected computers and can to support one or more transport layer protocols. A first overlay network is generated on top of the host network. The first overlay network includes one or more first-level nodal entities. At least some of the first-level nodal entities operate as factories for generating second-level nodal entities in a second overlay network. In response to receiving an instruction, one or more factories dynamically generate the second overlay network. The second overlay network includes several networked second-level nodal entities that can support data processing and data communication between the second-level nodal entities. | 08-16-2012 |
20120246295 | Real Time Distribution of Layered Communication Using Publish-Subscribe Data-Centric Middleware - Methods and apparatus, including computer program products, implementing and using techniques for organizing a communication session between two or more media aware network entities in a computer network. A computer network includes several media aware network entities (MANEs). The MANEs include data writers and data readers. A model for communication between the MANEs is provided. The communication model includes: subsets of planes associated with a session between two or more MANEs in a domain, each plane representing a collection of MANEs partaking on a subset of topics within the domain; a complementary subset of planes common to all participating MANEs of a domain, an aggregation of domains and topics, and methods for addressing namespaces within the topics. Data streams are exchanged in a session between two MANEs in the computer network according to the communication model. Techniques for distributing a data stream in a computer network are also described. | 09-27-2012 |

20140145930 | Computer Interface Employing a Manipulated Object with Absolute Pose Detection Component and a Display - A system with a remote control or wand equipped with a relative motion sensor that outputs data indicative of a change in position. The system has one or more light sources and a photodetector that detects their light and outputs data indicative of the detected light. One or more controllers are used to determine the absolute position of the wand based on the data output by the relative motion sensor and by the photodetector. The wand's absolute pose is determined from the data and includes the absolute position of a reference point on the wand and the wand's absolute orientation.
