Research on Weapon Human-Machine Interface Ergonomics Based on Visual Spatial Characteristics

For the faulty of current human-machine interface (HMI) ergonomic evaluation of weapon systems, the model of ergonomics assessment was established based on the spatial characteristics of human visual. In the model, the adaptability between human-machine interface design and visual features was evaluated from four aspects: The vertical vision, the level vision, visual angle and visual field, respectively. The probability of the effective operation of the operator was also observed. Experimental result showed that the model directly reflected the existing problems in human-machine interface ergonomics design, which could supply references for optimizing of human-machine interface design of weapon systems.
