Study of visual, tactile, and proprioceptive orientation

我们通过视觉、触觉和本体感觉来感知方向。在日常生活中，这些感觉系统共同构建视觉空间。这个为期三年的项目的目的是研究这些系统在方向感知方面的特征，以及这些系统如何整合感官信息。在这一年里，我们回顾了过去两年的研究成果，并补充了一些完成项目所需的实验。首席研究者研究了1)从两腿之间看到的目标的感知大小和感知距离，2)自滚运动的感知距离、感知速度和感知时间，3)触觉定向恒常性，4)地板表面的感知倾斜度，其他研究者研究了：1)触觉-动觉空间中自我中心的变异性；触觉本体感觉与视觉自我中心的关系，眼动与重力的相互作用，人脸方位和光照方位对人脸印象的影响，以及倾斜的光学几何错觉。这些研究成果已经或即将在专业期刊上发表。

We perceive orientation by vision, touch, and proprioception. In everyday life, these sensory systems cooperate to construct visual space. The aim of this three-year project was to investigate what characters each of these systems has regarding perception of orientation and how these systems integrate sensory information. In this year, we reviewed the research that has done for two years and supplemented some experiments that are needed to complete the project. The head investigator studied1) perceived size and perceived distance of the targets seen from between the legs,2) perceived range, perceived velocity, and perceived time of self-motion in roll,3) tactile orientation constancy, and4) perceived slant of a floor surfaceand other investigators studied :1) variability of the egocenter in tactile-kinesthetic space, and the relation between the tactile-proprioceptive and the visual egocenters,2) interaction between eye movement and the gravity,3) the effects of face orientation and illumination orientation on face impression, and4) optical geometric illusion regarding tilt.The outcomes of these researches were published or will be published in near future in professional journals.
