Anti-Mistouch Design and Usability Evaluation of Aircraft Human-Machine Interaction Touch Interface for Dynamic Environments

Abstract

With the technological advancement of integrated modular avionics, touch interaction has gradually replaced traditional key-based operations in aircraft human-machine interaction. Pilots often operate in dynamic environments and under high-load operational tasks, making it difficult to maintain precise and efficient control, thereby increasing the risk of human errors. This study aims to optimize the anti-mistouch design of touch elements in human-machine interaction (HMI) of aircraft cockpits. Fifteen pilots with more than 200 flight hours were recruited as participants. Based on task analyses of typical aircraft operations and research on factors affecting touch interaction performance, a design optimization strategy for aircraft HMI interfaces was developed. Rapid prototyping tools for HMI interfaces were adopted to develop interactive interfaces with different indicator characteristics. In a dynamic flight simulation environment, HMI ergonomics evaluation software was used to accurately record performance data of typical operations, and rating scales was applied to assess user satisfaction. The results show that the touch interface with the anti-mistouch design mechanism reduced the average task completion time by 12.5%, decreased the operation error frequency by 15.4%, and improved the user usability evaluation by 8.5%.
