受试者相对于地球的两种完全不同的运动可以对前庭、躯体感觉和视觉系统产生完全相同的刺激。当这种情况发生时，受试者可能会体验到对自我运动的迷失和误解。我们已经确定了在三种情况下在感知上相等的大类运动，即受试者无法区分的运动：无视觉、有视觉和地球固定的视觉环境，以及在视觉环境可能运动的过程中有视觉。对于每一组条件，我们都根据它们的知觉等价性对所有持续运动进行了分类。结果是一个完整的列表，列出了在给定条件下，由于力和其他直接刺激对传感器的等价性而可能产生的对持续运动的误解。这项研究通过包括线速度、角速度和加速度的所有分量，扩大了可能的实验范围。这篇论文中的许多预测都可以通过实验进行验证。此外，这里开发的等价类预测了在实验室很难或不可能研究的异常运动环境中的感知现象。
Two completely different motions of a subject relative to the earth can induce exactly the same stimuli to the vestibular, somatosensory and visual systems. When this happens, the subject may experience disorientation and misperception of self-motion. We have identified large classes of motions that are perceptually equivalent, i.e. indistinguishable by the subject, under three sets of conditions: no vision, with vision and earth-fixed visual surround, and with vision during possible movement of the visual surround. For each of these sets of conditions, we have developed a classification of all sustained motions according to their perceptual equivalences. The result is a complete list of the possible misperceptions of sustained motion due to equivalence of the forces and other direct stimuli to the sensors under the given conditions. This research expands the range of possible experiments by including all components of linear and angular velocity and acceleration. Many of the predictions in this paper can be tested experimentally. In addition, the equivalence classes developed here predict perceptual phenomena in unusual motion environments that are difficult or impossible to investigate in the laboratory.
