Abstract
An apparatus equipped with an electronic camera, lensed optics, and a visual display in communication with the optics. An analog or digital video signal is conveyed to an operator of the apparatus through the visual display. The apparatus includes an embedded processor to track the orientation and position of the apparatus. Orientation and position information of the apparatus is used to dynamically recalculate display information. In addition, the apparatus may be in communication with a remote device having digital camera optics. Orientation and position information of the apparatus may be conveyed to the remote device to alter the orientation and position of the associated electronic camera optics. The global position and orientation data is refined through the use of a machine vision algorithm. Accordingly, data conveyed to the operator of the apparatus is in relation to the orientation and position of the apparatus and/or the associated orientation and position of the remote device.
