Abstract

Three-dimensional display technology has developed rapidly in recent years. There are also various types of telop, in which text information moves on a screen. We carried out experiments targeting about the 100 young and elderly subjects to verify the visibility of 3D images contained in text information. The aim of this study was to observe reading of the characters and how easy-to-read the display types were for 3D images. We examined the maximum distance in which subjects' eyes could recognize the 3D character representations without any difficulty or discomfort and validated popping distance using character information from 3D images that popped up from the background of stereoscopic images. We analyzed the effects of the virtual positions of the 3D texts. There was no significant difference between the theoretical and observed values in any age groups. We have found that even in the text protrusion of the large parallax, it is possible to recognize the position that pop out.
