Abstract

Auto-guidance of a mobile machine is provided that does not require a graphical user interface display. Human interactions with the auto-guidance system of a mobile machine are performed solely with one or more electromechanical switches of the auto-guidance system while the mobile machine is operating. A first point for auto-guidance of a mobile machine is set by an auto-guidance system in response to a first electromechanical switch input. A second point for auto-guidance of the mobile machine is set by the auto-guidance system in response to a second electromechanical switch input after movement of the mobile machine from the first point. The auto-guidance system activates auto-guidance of the mobile machine along a path defined by the first point and the second point. The setting of the first point, the setting of the second point, and the activating are performed by one or more hardware processors.
