摘要：在搜索叠加在背景上的单词时，探索了立体观看的好处。在第一个实验中，八名参与者在普通 2D 显示器、使用视差屏障的 3D 显示器以及与 3D 显示器亮度相当的暗化 2D 显示器中搜索文本。与 3D 显示器相比，明亮的 2D 显示器的单词搜索性能明显更快，但当控制亮度时，3D 显示器的性能相对于 2D（暗淡）显示器更好。在第二个实验中，在四种背景条件下评估了浮动文本与下沉背景视差的影响。 20 名参与者仅看到浮动文本 (FT) 条件，20 名参与者仅看到下沉背景 (SB) 条件。 SB组的表现明显优于FT组，并且背景越复杂，SB差异的优势越大。因此，当使用视差屏障 3D 显示器来查看覆盖在背景上的文本或其他图形信息时，建议主要兴趣层（前景）应以零视差（在物理显示表面上）显示，而次要层（背景）似乎沉入该表面下方。
Abstract— The benefits of stereoscopic viewing were explored in searching in words superimposed over a background. In the first experiment, eight participants searched for text in a normal 2‐D display, a 3‐D display using a parallax barrier, and a darkened 2‐D display of equivalent brightness to the 3‐D display. Word‐search performance was significantly faster for the bright 2‐D display vs. the 3‐D display, but when brightness was controlled, performance on the 3‐D display was better relative to the 2‐D (dim) display. In a second experiment, the effect of floating text vs. sinking background disparity was assessed across four background conditions. Twenty participants saw only the floating‐text (FT) condition and 20 participants saw only the sinking‐background (SB) condition. Performance of the SB group was significantly better than that of FT group, and the advantage of SB disparity was greater with the more‐complex backgrounds. Thus, when a parallax‐barrier 3‐D display is used to view text or other figural information overlaid on a background, it is proposed that the layer of primary interest (foreground) should be displayed with zero disparity (on the physical display surface) with the secondary layer (background) appearing to be sunk beneath that surface.
