A network of scopes, including one or more lead scopes and one or more follower scopes, is provided to allow the respective scopes to track the same presumed target. A lead scope locates a target and communicates target position data of the presumed target to the follower scope. The follower scope uses the target position data and its own position data to generate electronic control signals for use by follower scope to make position movements so as to re-position the follower scope from its current target position to move towards the target position defined by the target position data received from the lead scope. At least the second scope is mounted to, or integrated into, a vehicle, which uses the target position data to move to a new location so as to allow the second scope to better view the target.

There is provided a system and method for converging mediated reality (MR) positioning data and geographic positioning data. The method including: receiving three or more geographic coordinate points, the geographic coordinate points each associated with different points in time; receiving three or more MR coordinate points, each of the MR coordinate points associated with one of the points in time; determining a geographic trend line from the geographic coordinate points; determining an MR trend line from the MR coordinate points; determining a correction angle as an angle between the geographic trend line and the MR trend line; and outputting the correction angle.

Examples of systems and methods for locating movable objects such as carts (e.g., shopping carts) are disclosed. Such systems and methods can use dead reckoning techniques to estimate the current position of the movable object. Various techniques for improving accuracy of position estimates are disclosed, including compensation for various error sources involving the use of magnetometer and accelerometer, and using vibration analysis to derive wheel rotation rates. Also disclosed are various techniques to utilize characteristics of the operating environment in conjunction with or in lieu of dead reckoning techniques, including characteristic of environment such as ground texture, availability of signals from radio frequency (RF) transmitters including precision fix sources. Such systems and methods can be applied in both indoor and outdoor settings and in retail or warehouse settings.

A navigational device includes a microprocessor, a target marking system, a digital tilt sensor, and a digital compass to determine mapping coordinates of a remote point from an observation point. A user first visually targets the remote point using the target marking system. The digital tilt sensor then determines an angle of inclination to the remote point from the observation point. The digital compass then determines a bearing angle to the remote point from the observation point. The GPS module then determines the GPS coordinates of the observation point. Lastly, the microprocessor determines mapping coordinates of the remote point based upon the angle of inclination data, the angle of bearing data, and the GPS coordinates of the observation point.
