近年来，虚拟现实（VR）受到越来越多的关注。对于虚拟现实的发展，人类的识别机制是一个至关重要的因素。以往的视觉识别神经影像学研究发现，视网膜视野偏心率不同，识别机制也不同。例如，当我们识别人脸、建筑物和场景时，我们使用中央视野。然而，不仅中心视野，而且周边视野用于建筑物识别。而对于场景的识别来说，周边视野比中心视野更重要。要揭示物体识别的机理，就必须明确中央视野和周边视野的功能。本研究的目的是揭示中央视野和周边视野的物体识别机制的第一步。我们分析了视网膜偏心率的对象的基本元素的依赖性。视网膜偏心率是中心视野和周边视野之间的差距的程度。基本上，我们测量的依赖性识别视网膜偏心的视野，因为我们改变了元素和曝光时间的刺激。对象的基本要素是刺激的大小和刺激的线宽。刺激的大小和刺激的线宽显示出很大的依赖性视网膜偏心的视野。但刺激的曝光时间对视网膜视野偏心率的依赖性较小。
Recently, virtual reality (VR) have received increasing attention. For the development of VR, human recognition mechanism is a crucial factor. Previous neuroimaging studies of the visual recognition have found that mechanism of recognition is different on retinal eccentricity of visual field. For example, when we recognize the face, the building and the scene, we use the central vision field. However not only the central vision field but also the peripheral vision field is used for building recognition. And for the recognize of the scene, the peripheral vision field is even more important than central vision field. Revealing the object recognition mechanism demands us to clarify the functions of the central and the peripheral vision field. The purpose of this study is the first step to reveal the object recognition mechanism of the central and the peripheral vision field. We analyze the dependency of the fundamental elements of the objects on retinal eccentricity. The retinal eccentricity is the degree of the gap between the central and the peripheral vision field. Basically, we measured the dependency of recognition on retinal eccentricity of visual field as we changed the elements and the exposure duration of stimuli. The fundamental elements of the objects are the stimuli size and the line width of the stimuli. The stimuli size and the line width of the stimuli showed a large dependency on retinal eccentricity of visual field. But the exposure duration of stimuli showed a small dependency on retinal eccentricity of visual field.
