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 |

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. A display is used to show an image defined by two orthogonal axes, e.g., those of world coordinates (X | 05-29-2014 |
20140268318 | ARRAYED DUAL AXIS CONFOCAL MICROSCOPES - Various aspects as described herein are directed to apparatuses, methods, and systems including a sandwiched arrangement having a light-access port, a scanning mirror, an optics region, and a spacer. The spacer provides a light-directing optical region that separates the scanning mirror and the optics region, and includes a mirrored surface that reflects light between the light-access port and the optics region. Additionally, the optics region includes a curved-shaped window that provides a field of view by communicating beams of light between a target region. The optics region also includes a curved-shaped mirror having a surface that reflects light between the scanning mirror and the mirrored surface. Light beams, as conveyed between the light-access port and the curved-shaped window, are folded by being reflected off the scanning mirror, the curved-shaped mirror and the mirrored surface. | 09-18-2014 |
20150276400 | REDUCED HOMOGRAPHY FOR ASCERTAINING CONDITIONED MOTION OF AN OPTICAL APPARATUS - A method of tracking a conditioned motion with an optical sensor that images a plurality of space points. The method includes a) recording electromagnetic radiation from the space points on the optical sensor at measured image coordinates of measured image points, b) determining a structural redundancy in the measured image points due to the conditioned motion, and c) employing a reduced representation of the measured image points by a plurality of rays defined in homogeneous coordinates and contained in a projective plane of the optical sensor consonant with the conditioned motion for the tracking. | 10-01-2015 |
