视觉诱导向量是由视觉刺激(如点云)引起的自我运动的错觉,模拟当代理在空间中移动时所看到的东西。足够的刺激参数,以产生vection是未知的,但阐明这是在更高的(认知)神经系统疾病的视觉和前庭处理之间的关系受到干扰的研究的兴趣。在这里,我们选择性地消除径向运动角度的矢量显示器,并表明,矢量仍然存在,虽然比正常的光流弱,矢量强度是惊人的变量在个人之间。
Visually induced vection is the illusory sensation of self-motion caused by visual stimuli (such as a dot cloud) that emulate what is seen when an agent moves through space. The sufficient stimulus parameters to generate vection are unknown, but elucidating this is of interest in the study of higher (cognitive) neurological disorders where the relationship between visual and vestibular processing is disturbed. Here, we selectively eliminate that radial motion angle from vection displays and show that vection is still present, although weaker than during normal optic flow, and that vection strength was strikingly variable across individuals.
