摘要： The present invention relates to a jotting implement that infers hand-jotted information from viewing a jotting surface and environmental landmarks. The hand-jotted information is any information marked on the jotting surface as a result of writing, jotting, drawing, sketching or otherwise operating on the jotting surface as well as hand-generated information produced by moving the implement in the air with respect to the jotting surface. The jotting implement has a nib for jotting and an arrangement for determining when the nib is jotting on the jotting surface. Further, the implement has an optical unit for viewing an environmental landmark and the jotting surface. The implement has a processing unit for receiving optical data of the environmental landmark and the jotting surface from the optical unit and determining from the optical data the physical coordinates of the nib with respect to the jotting surface. The environmental landmark is preferably made up several beacons that emit electromagnetic radiation and are affixed to a host structure.

摘要： The present invention relates to an optical navigation system for determining a pose, which includes the position and orientation of an object in an environment. The optical navigation system uses a number of beacons affixed at known locations in the environment to provide electromagnetic radiation in a sequenced pattern. An on-board optic images the radiation from the beacons onto an on-board centroid sensing device to obtain an imaged distribution of the radiation on the on-board centroid sensing device. The centroid sensing device determines the centroid of the imaged distribution and provides centroid information to a navigation unit for determining the pose of the object from the centroid. The navigation system is particularly well-suited for navigating hand-held objects.

摘要： 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 (Xo,Yo,Zo) with respect to a reference location, such as, for example, the world origin. Other conventions for expressing absolute pose data in three-dimensional space and representing all six degrees of freedom (three translational degrees of freedom and three rotational degrees of freedom) are also supported. Irrespective of format, a processor prepares the absolute pose data and identifies a subset that may contain all or fewer than all absolute pose parameters. This subset is transmitted to an application via a communication link, where it is treated as input that allows a user of the manipulated object to interact with the application and its output.

摘要： 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.

摘要： 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 (Xo,Yo,Zo). The one or more controllers are configured to generate signals that are a function of the absolute position of the wand in or along a third axis for rendering the display. To simplify the mapping of a real three-dimensional environment in which the wand is operated to the cyberspace of the application that the system is running, the third axis is preferably the third Cartesian coordinate axis of world coordinates (Xo,Yo,Zo).
