1. A computer-implemented method to continuously maintain and improve alignment between two associated coordinate systems, by moving a follow coordinate system to align it to a lead coordinate system during a session, the method comprising the steps of:
executing a software loop process comprising the steps of:
identifying and activating a first cell in a leadSpace coordinate system, wherein the leadSpace coordinate system is one of the two associated coordinate systems;
automatically selecting and activating surrounding cells near a point of focus according to a relative position of the surrounding cells to the point of focus;
acquiring three points within the leadSpace coordinate system and corresponding locations in a followSpace coordinate system, wherein the followSpace coordinate system is the second associated coordinate system of the two associated coordinate systems;
receiving a transformation for alignment of the two associated coordinate systems at the point of focus; and
moving the followSpace coordinate system to align to the lead coordinate system at the point of focus.
