• a fill control application configured to run on a mobile device, the mobile device including a mobile device communication system configured to communicate with a material loading vehicle communication system on a material loading vehicle, the application including:
• a command processing system that receives a motion adjustment command from the material loading vehicle, the motion adjustment command comprising a relative position adjustment command requesting a change in position of a receiving vehicle, that receives material from the material loading vehicle, relative to the material loading vehicle;
• and
• an output generator configured to generate a representation of a visual adjustment indicator indicative of a direction of the requested change in the position of the receiving vehicle relative to the material loading vehicle, the visual adjustment indicator including an image of the receiving vehicle and a direction indicator indicating the direction of the requested change in the position of the receiving vehicle relative to the material loading vehicle;
• an interface control signal generator configured to generate interface control signals based on the representation of the visual adjustment indicator;
• and
• a user interface mechanism coupled to the output generator, the user interface mechanism comprising a display screen configured to display the visual adjustment indicator based on the interface control signals.
