This paper designs a visible human-machine interface for field computer in an agriculture vehicle navigation control system. Field computer, with the function of system configuration, vehicle configuration, steering configuration, job management, path planning and map views, is the human-machine interface in agriculture vehicle navigation control system. This paper introduces the design of map views including field view and machine view for field computer system based on coordinate conversion. Field View gives a bird’s eye view of the map. The agriculture vehicle moves while the map keeps stationary. Machine view keeps agriculture vehicle in center of screen, while the map moves along the reverse direction of the agriculture vehicle.
