Efficiency of Touch Gestures in Military Vehicles: Impact of Vibration on Task Performance and Physiological Responses

This study employs a six‐degree‐of‐freedom motion simulation platform to replicate vibration signals encountered by military vehicles traversing diverse terrain conditions. The objective is to investigate how task performance and physiological responses of participants vary when executing specific tasks using typical touch gestures under different vibration frequencies. Results demonstrate that vibration environments significantly impact touch interaction performance. Among all tested gestures, the Tap+Slide gesture exhibited the best operational performance. Although it required relatively higher muscular effort, it showed the lowest overall fluctuation in skin conductance response. These findings offer valuable insights for the adaptive design of touch gesture encoding in control interfaces for specialized and military vehicles operating under vibration. Moreover, they contribute to enhancing the safety of touch interaction during vehicle operation and have implications for improving human–vehicle interaction safety in both civilian and commercial applications.
