Controling pivot angle of camera pivotable by remote control involves moving camera at speed proportional to distance detected between null point and control unit's relative position

摘要

The method involves detecting the position of a control unit for a computer graphical user interface, comparing it with control field boundary coordinates and, if the position is in the control field, determining the current position relative to a null point in the control field, computing the drive angle for at least 2 motors and moving the camera at a speed proportional to the distance detected between null point and current relative position.
