Application and research of touch screen in human-computer interaction technology in the cockpit of civil aircrafts

With the wide application of touch technology in civil equipment, the effectiveness of its human-computer interaction has been significantly improved, greatly optimizing the user's operating experience. Based on its advantages of efficient interaction, this technology has been gradually introduced into the aviation field, and some aircraft manufacturers have begun to adopt touch interaction interfaces in cockpit design. However, under the high-vibration working condition of the aircraft, the input efficiency problem of touch operation has become more and more prominent, which has become one of the key factors affecting flight safety. Based on the specific human-computer interaction environment in the cockpit of a civil aircraft, this study scientifically classifies the amplitude of pilots' hand movements into three levels: high, medium, and low, through experimental measurements and theoretical analyses. On the basis of systematically sorting out the existing research results, we compare and analyze the various solutions to the touch misoperation problem proposed by scholars at home and abroad. We innovatively propose a hierarchical optimization strategy: for small-amplitude operation conditions, we adopt the design scheme of an enhanced haptic feedback mechanism; for medium-amplitude and high-amplitude operation scenarios, we adopt line-of-sight tracking-assisted unlocking technology. Finally, the reasonableness and effectiveness of the scheme are confirmed through validation experiments. The results of this study provide a theoretical basis and technical support for the optimal design of the cockpit touch interaction system of civil aircraft, which has important engineering application value for ensuring aviation safety.
