Motion perception in a full-immersion virtual environment

运动处理是最基本的知觉功能之一，因为它对于避免潜在的危险事件至关重要，并被人类用来允许与环境交互。这里提出的研究计划是我们之前关于使用全沉浸式虚拟环境进行运动处理的基本方面工作的继续(5)。该项目提出了研究光流对姿势控制的影响等内容。光流是在环境中运动时从视觉场景中的元素感受到的运动类型，被认为是生态的。负责感知光流的机制将作为正常发育和视野特征的函数进行研究。此外，还将在身临其境的虚拟现实环境中评估在大型三维体积空间中跟踪多个运动元素的能力。这个项目的研究将帮助我们更好地理解我们如何感知、整合以及如何在类似于一些自然主义背景的大范围三维条件下使用动态视觉信息。

Motion processing is one of the most fundamental perceptual functions as it is essential to avoid potentially dangerous events and is used by humans to allow interaction with the environment. The research program proposed here is a continuation of our previous work on basic aspects of motion processing using a full-immersive virtual environment (FIVE). The program proposes among other things to study the effects of optic-flow on postural control. Optic-flow is the type of motion that is perceived from elements in the visual scene while moving in the environment and is considered to be ecological. Mechanisms responsible for perceiving optic flow will be studied as a function of normal development and visual field characteristics. Furthermore, the capacity for tracking multiple moving elements in a large three-dimensional volumetric space will also be assessed within the immersive virtual reality environment. The research derived from this program will help us better understand how we perceive, integrate and how we can use dynamic visual information in large field three-dimensional conditions similar to some naturalistic contexts.
