Spatial disorientation and visual channel saturation are defined as critical situations encountered by military pilots. Such subjects are interesting research areas likely to create innovative systems able to surmount obstacles of this kind. The integration of new stimulation techniques (sensory substitute, adjunct for visual and audio feedback) may be considered to make the visual channel better. This contribution may help in integrating tactile stimulation to improve or substitute the visual channel. It may also help to better interpret the spatial disorientation awareness signals and the vestibulo-ocular response limitations. The innovation of the proposed approach translates in: (i) the development of the PI-Inverse dynamics controller to provide a time delay reduction of the low cost tactile actuator, and thus, high-performance tactile system; (ii) an approach based on fuzzy logic controller (FLC) is being used in order to translate the turn rate angle, the flight path climb angle and the warning messages into tactile signal features instead of a conventional approach based on direct coding of the pitch and bank angles; and (iii) the consideration of the flight envelope. The fuzzy set translation of flight parameters into tactile signals is also a pragmatic and useful way to design the system.
空间迷向和视觉通道饱和被定义为军事飞行员遇到的关键情况。这些主题是有趣的研究领域，可能会创造出能够克服这种障碍的创新系统。整合新的刺激技术（感觉替代、视觉和音频反馈的辅助）可以考虑使视觉通道更好。这一贡献有助于整合触觉刺激以改善或替代视觉通道。它还有助于更好地解释空间迷向意识信号和前庭眼动反应的限制。所提出方法的创新体现在：（i）开发 PI 逆动力学控制器，以减少低成本触觉执行器的时滞，从而实现高性能触觉系统；（ii）采用基于模糊逻辑控制器（FLC）的方法，将转弯率角、飞行路径爬升角和警告消息转换为触觉信号特征，而不是传统的基于俯仰和倾斜角直接编码的方法；（iii）考虑飞行包络。将飞行参数转换为触觉信号的模糊集翻译也是设计系统的一种实用且有用的方法。
