Research Initiation: Displaying Three-Dimensional Computer Aided Design Models Using Stereoscopic and Monocular DisplayCoding Techniques

提供复杂物体的三维模型对于许多应用来说是很重要的。不幸的是，显示器的二维特性使得复杂的三维对象的可视化变得困难。观察者需要通过整合从使用单目深度线索作为编码技术的二维视图接收到的视觉信息来建立三维物体的心理模型。目前有一种新的显示技术可以提供立体视觉的双目深度提示。当图像中可用的单目线索很少时，该线索可能是有利的。该研究的目的是调查用于呈现三维对象的视觉表示的单视显示技术与立体显示技术的相对优点。假设这两种技术的有效性将取决于对象的复杂性和可用的单目线索的数量。这项研究将试图确定使用立体编码技术与使用心理旋转范式的单视觉编码技术是否存在权衡。图像将使用立体线索和各种单目编码技术来创建，包括隐藏线移除、阴影、纹理和旋转。图像中可用的单目线索的数量会有所不同。这项经验研究将提供关于使用立体显示作为提供对象的三维表示的工具的所需数据，并提供关于立体显示是否是高成本图形处理技术的可行替代方案的洞察。

Providing three-dimensional models of complex objects is important for many applications. Unfortunately, the two- dimensional nature of displays makes visualization of complex three-dimensional objects difficult. Observers are required to develop mental models of three-dimensional objects by integrating visual information received from two-dimensional views which used monocular depth cues as coding techniques. A new display technology is currently available that provides the binocular depth cue of stereopsis. This cue may be advantageous when few monocular cues are available in the image. The objective of the research is to investigate the relative merits of monoscopic versus stereoscopic display techniques for presenting visual representations of three-dimensional objects. It is hypothesized that the effectiveness of both techniques will depend upon object complexity and the number of monocular cues available. The research will attempt to determine if a trade-off exists for using stereoscopic versus monoscopic coding techniques using a mental rotation paradigm. Images will be created using the stereoscopic cue and a variety of monocular coding techniques including hidden line removal, shading, texture and rotation. The number of monocular cues available in an image will be varied. This empirical research will provide needed data on the use of stereoscopic displays as a tool for providing three-dimensional representations of objects, and provide insight as to whether stereoscopic displays are feasible alternatives to high cost graphic processing techniques.
