追求基于人类视觉感知的新显示技术可以为视觉信息呈现开辟新的可能性。在这里，我们提出了一种信息显示方法的巨大改进，我们称之为基于扫视的显示。基于扫视的显示器可以显示二维 (2D) 图像，无需任何屏幕，仅使用单行闪烁发光二极管 (LED)。以下原则是实现该显示的基础。众所周知，一维闪烁LED阵列的机械高速运动可以通过视网膜残像呈现2D图像（这种视觉显示器是商业上可用的[IMS 2000]），相反，当光源固定在垂直线上，并且在称为扫视的水平快速眼球运动期间闪烁模式快速改变时，由于人类视觉系统中的时空整合，也可以感知2D图像，如图1所示。 1（一）。当一条垂直的光线在水平扫视期间快速闪烁时，闪烁图案会通过眼球运动扩展为空间图案。在眼球运动过程中，垂直光阵列在视网膜上传播，同时改变闪烁模式。然后，不同视网膜位置的不同垂直图像被整合成二维图像，如图1所示。 1(b)。尽管在日常生活中很难看到扫视期间呈现的图像（例如[Latour 1962]），但是可以识别这种显示器呈现的具有高对比度和高空间频率的图像[Watanabe et al. 2017]。 2005b][渡边等人。 2005a]。
Pursuing new display techniques based on insights of human visual perception can open up new possibilities for visual information presentation. Here we present the vast refinement of an information display method, which we call a saccade-based display. The saccade-based display can show two-dimensional (2D) images without any screen using only a single line of flickering light emitting diodes (LEDs). The following principle is fundamental to the implementation of this display. It is known that mechanical high-speed movement of a one-dimensional flickering LED array can present 2D images through retinal afterimages (this kind of visual display is commercially available [IMS 2000]) Conversely, when light sources are fixed on a vertical line, and the flashing pattern is changed quickly during a horizontal rapid eye movement called a saccade, 2D images can also be perceived due to spatio-temporal integration in the human vision system as in fig. 1(a). When a vertical line of lights flashes quickly during the horizontal saccade, the flashing pattern is expanded into a spatial pattern by the eye movement. During the eye movement, the vertical light array travels on the retina while changing the flashing pattern. Then, the different vertical images at different retinal locations are integrated into a 2D image as in fig. 1(b). Although the images presented during the saccade can hardly be seen in daily life (e.g. [Latour 1962]), the images with high contrast and high spatial frequency as presented with this display can be recognized [Watanabe et al. 2005b][Watanabe et al. 2005a].
