Abstract
In an AR environment in which the pointing direction of the video camera is slaved to field technician motion to capture a video signal within a camera FOV of an object at arm's length from the technician and remotely-generated hand gestures for manipulation of the object are overlaid on the video signal to instruct the technician in manipulation of the object, a customer-defined key code and FOV limitations are used to exclude portions of a scene for data capture and transmission compliance. If the video camera pointing direction does not satisfy an alignment condition to a marker in the scene, the camera is controlled to exclude at least a portion of the camera FOV that lies outside a user-defined allowable FOV from capture within the video signal. The customer-defined key code includes at least technician identification, marker pairing and specified tolerance fields that define the allowable FOV. The key code allows the technician to control the FOV exclusions to protect the technician from capturing and/or transmitting data in the scene that would violate customer or country policies or legal requirements.
