Measurements are made of manual control performance in the closed-loop task of nulling perceived self-rotation velocity about an earth-vertical axis. Self-velocity estimation is modeled as a function of the simultaneous presentation of vestibular and peripheral visual field motion cues. Based on measured low-frequency operator behavior in three visual field environments, a parallel channel linear model is proposed which has separate visual and vestibular pathways summing in a complementary manner. A dual-input describing function analysis supports the complementary model; vestibular cues dominate sensation at higher frequencies. The describing function model is extended by the proposal of a non-linear cue conflict model, in which cue weighting depends on the level of agreement between visual and vestibular cues.
对消除围绕地球垂直轴的感知自我旋转速度的闭环任务中的手动控制性能进行了测量。自我速度估计被建模为前庭和周边视野运动线索同时呈现的函数。基于在三种视野环境中测量到的低频操作员行为,提出了一种并行通道线性模型,该模型具有以互补方式求和的独立视觉和前庭通路。双输入描述函数分析支持互补模型;前庭线索在较高频率下主导感知。通过提出非线性线索冲突模型扩展了描述函数模型,其中线索加权取决于视觉和前庭线索之间的一致程度。
