SummaryMeasurements是由手动控制性能的闭环任务归零感知自转速度围绕地球垂直轴。自我速度估计被建模为前庭和周边视野运动线索的同时呈现的函数。基于三个视野环境中测得的低频操作员行为，提出了一种并行通道线性模型，该模型具有单独的视觉和前庭通路，以互补的方式求和。双输入描述功能分析支持的互补模型，前庭线索占主导地位的感觉在较高的频率。描述函数模型扩展的建议，一个非线性的线索冲突模型，其中线索加权取决于视觉和前庭线索之间的协议水平。
SummaryMeasurements 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.
