Graphical user interface for a remote operated vehicle

摘要

A graphical user interface (GUI) for a remote operated vehicle (ROV) with an onboard video camera with pan-and-tilt mechanism. A broad translucent compass bearing icon is arranged horizontally with compass bearing marks that scroll to the left and right as the ROV moves to the right and left respectively, thereby giving the user visual feedback for steering the ROV as well as hard information relating to the bearing. The translucency allows a large icon area to be provided without blanking out the video footage. A long translucent depth icon is arranged vertically with depth reading marks that scroll up and down as the ROV moves down and up respectively. A pan-and-tilt icon at the top center of the screen gives user feedback as to the direction in which the ROV camera is pointing relative to the ROV. Status indicator icons are provided on the left side of the screen. These and the other icons are inserted and removed by special bum-in and fade-out processes to provide good visibility at the same time as continuity of viewing. A transient speed icon shows changes in available power to the ROV thrusters.
