We describe a mobile app that measures early cortical visual processing suitable for use in clinics. The app is called (CEMIT). Observers are asked to respond to the direction of translating plaids that move in one of two very different directions. The plaids have been selected so that the plaid components move in one of the directions and the plaid pattern moves in the other direction. In addition to correctly responding to the pattern motion, observers demonstrate their ability to correctly extract the movement (and therefore the orientation) of the underlying components at specific spatial frequencies. We wanted to test CEMIT by seeing if we could replicate the observed at low spatial frequencies for this type of plaid. Results from CEMIT were robust and successfully replicated this result for 50 typical observers. We envisage that it will be of use to researchers and clinicians by allowing them to investigate specific deficits at this fundamental level of cortical visual processing. CEMIT may also be used for screening purposes where visual information plays an important role, for example, air traffic controllers.
我们描述了一款适用于临床的、用于测量早期皮质视觉处理的移动应用程序。该应用程序名为（CEMIT）。要求观察者对朝两个非常不同方向之一移动的平移光栅的方向做出反应。选择这些光栅是为了使光栅的组成部分朝一个方向移动，而光栅图案朝另一个方向移动。除了正确响应图案运动外，观察者还展示了他们在特定空间频率下正确提取底层组成部分的运动（以及因此的方向）的能力。我们想通过观察是否能复制针对此类光栅在低空间频率下观察到的[具体内容缺失]来测试CEMIT。CEMIT的结果很可靠，并成功地为50名典型观察者复制了这一结果。我们设想，它将对研究人员和临床医生有用，使他们能够在皮质视觉处理的这一基本层面上研究特定缺陷。CEMIT也可用于视觉信息起重要作用的筛查目的，例如空中交通管制员。
