Investigating the neuro-cognitive fundaments of the perception of illusory self-motion

自我运动的感知是由不同感觉信息的整合引导的，包括视觉、前庭（内耳）和本体感受（肌肉和关节的位置）线索。这些感官传递的信息通常是一致的，从而产生对空间运动的全局、准确的感知。然而，在某些情况下，虚幻的自我运动或矢量（即，尽管没有真实的物理运动，但也可以体验自运动感知）。现实世界中的一个例子是火车错觉，即坐在一辆静止的火车上，看到相邻的火车移动，就会产生自己的火车正在移动的错觉。矢量也可以在刺激大部分视野的情况下观察到，例如在模拟器或虚拟现实（VR）中，并且在这些应用中起着重要作用。

The perception of self-motion is guided by the integration of different sensory information, including visual, vestibular (inner-ears), and proprioceptive (position of the muscles and joints) cues. Information delivered by these senses is typically congruent, giving rise to a global, accurate perception of movement through space. However, under certain circumstances illusory self-motion or vection (i.e., self-motion perception despite the absence of real, physical movement) can also be experienced. An example for vection in real-world situation is the train illusion, whereby sitting in a stationary train and seeing a neighboring train moving creates the illusion that one’s own train is moving. Vection can also be observed in situations that stimulate a large proportion of the visual field, such as in simulators or virtual reality (VR) and plays an important role in these applications.
