为了区分平动线性加速度和重力线性加速度，以及定位运动期间和运动后的“向上”（主观天顶，SZ）方向，耳石（线性加速度传感器）和耳道（角速度传感器）的相互作用对于人类的空间方向是必要的。在实验中，受试者被要求在运动刺激期间和之后动态调整显示到他们的主观垂直（SV），从而证实了当前交互模型的三个基本假设。由于平移加速度和重力加速度不能分开测量，因此本文提出的处理结构基于Mayne1首先提出的假设，即在低频范围内线性加速度被解释为重力加速度的变化。“眼重力错觉”实验中主观垂直（SV）的缓慢增长（见图1或参考文献2）验证了重力加速度估计使用低通滤波耳石传入的假设。
In order to discriminate between translatory and gravitational linear acceleration as well as to locate the direction of" up"(the subjective zenith, SZ) during and after movements an interaction of otoliths (linear acceleration sensors) and canals (angular velocity sensors) for human spatial orientation is necessary. Three basic assumptions underlying the present model of interaction are confirmed by experiments in which subjects were asked to adjust dynamically a display to their subjective vertical (SV) during and after motion stimuli.1. Since translatory and gravitational acceleration cannot be measured separately, the processing structure proposed here is based on the assumption first made by Mayne1, that in a low frequency range linear acceleration is interpreted as a change of gravitational acceleration. The slow increase of the subjective vertical (SV) in the" oculogravic illusion" experiment (see FIGURE 1 or, eg, Reference 2) validates the assumption that estimation of gravitational acceleration uses the low pass filtered otolith afferents.
