Study on perceptual properties of images presented by Saccade-based display — Asynchronous and depth perception

When we look at a one-dimensional light array while moving our eyes rapidly, the afterimage of the 1D light source will be spread on the retina so that we can recog-nize it as 2D image. Saccade-based display (SD), which uses this phenomenon and is composed of a 1D rapid blink-ing light-emitting diode (LED) array, can give the viewer the perception of a 2D image without a 2D screen. Percep-tion with SD is remarkably different from ordinary display because the process of perception is different from when we look without eye movement. To make use of these percep-tual properties for more effective presentation on SD, we performed experiments and found that some contents cause asynchronous and depth perception to the viewer. 1
