A method and apparatus for determining the position and orientation of a remote object relative to a reference coordinate frame includes a plurality of field-generating elements for generating electromagnetic fields, a drive for applying, to the generating elements, signals that generate a plurality of electromagnetic fields that are distinguishable from one another, a remote sensor having one or more field-sensing elements for sensing the fields generated and a processor for processing the outputs of the sensing element(s) into remote object position and orientation relative to the generating element reference coordinate frame. The position and orientation solution is based on the exact formulation of the magnetic field coupling as opposed to approximations used elsewhere. The system can be used for locating the end of a catheter or endoscope, digitizing objects for computer databases, virtual reality and motion tracking. The methods presented here can also be applied to other magnetic tracking technologies as a final "polishing" stage to improve the accuracy of their P&O solution.

A system and method for determining a position of a remote object comprising inertial sensors and three axis magnetic sensor, together with a target sighting device aligned with the observation platform to determine a target line of sight and a target range finder to determine a distance to the target along the line of sight. A GPS receiver may be included for determining an observation platform position and orientation, The three axis magnetic sensor provides both magnetic north and vertical attitude information for improved rapid initialization and operation in motion. Magnetic anomaly information is detected by comparing IMU and magnetic navigation information and by other methods. Target identification may be determined by a human operator and/or by computer. The system may be integrated with a weapon system to use weapon system sights. The system may be networked to provide target location and/or location error information to another identical unit or a command information system.

A multi-resolution object location system and method for locating objects is provided. The multi-resolution system and method uses a long-range object locator together with a more precise RFID locator to efficiently and accurately determine the location of objects that include an RFID tag. The long-range object locator has a relatively longer range and can cover a relatively large area to determine the general location of the object within the large area. The RFID locator has a relatively shorter range, but is able to locate the object more precisely. The object location system uses the long-range locator to first determine the general location of the object, and then the RFID locator is used to determine a more accurate location of the object. Thus, the multi-resolution object location system is able to provide both a long range location of objects over a large area and a precise location of objects.

An apparatus and process for controlling a remote robot responsive to the integrated sensory perceptions, natural body movements, inertia and gravitation of an operator/user who is himself responding to a three dimensional virtual world of visual and sensory conditions responsive to the environment at the remote site where the robot is operating. The user requires no training, special commands or devices to direct the robot because the user has the perception of actually being at the remote location, handling remote objects he sees and feels in his hands, walking, climbing, viewing and feeling the remote world.

The present invention discloses a system and method for non-holographic virtual teleportation of one or more remote objects to a designated three-dimensional space around a user in realtime. This is achieved by using a plurality of participating teleportation terminals, located at geographically diverse locations, that capture the RGB and depth data of their respective environments, extract RGB images of target objects from their corresponding environment, and transmit the alpha channeled object images via Internet for integration into a single composite scene in which layers of computer graphics are added in the foreground and in the background. The invention thus creates a virtual 3D space around a user in which almost anything imaginable can be virtually teleported for user interaction. This invention has application in intuitive computing, perceptual computing, entertainment, gaming, virtual meetings, conferencing, gesture based interfaces, advertising, ecommerce, social networking, virtual training, education, so on and so forth.

Disclosed is a method and apparatus for determining the risk of an object collision. The method includes transmitting a signal and analyzing a received signal that is indicative of the presence of a remote object. The signal is then analyzed to determine an initial azimuth value and an initial range for the remote object. Subsequent received signals are continuously analyzed to continuously determine subsequent azimuth values, azimuth value velocities and accelerations, as well as subsequent range values, range value velocities and range value accelerations. The factors are then input into a predetermined formula to yield a risk assessment of collision P. The formulas for determining P can be adjusted to account for such factors as number and proximity of remote objects, as well as the speed and maneuverability of both the remote objects and the vehicle that is avoiding collisions with the remote object(s).
