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许多应用都很重要。不幸的是，显示器的二维特性使得复杂的三维物体难以可视化。观察者需要通过整合从二维视图接收的视觉信息来建立三维物体的心理模型，这些视觉信息使用单目深度线索作为编码技术。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，这种线索可能是有利的。本研究的目的是探讨单镜与立体显示技术在呈现三维物体的视觉表现方面的相对优点。假设这两种技术的有效性将取决于物体的复杂性和可用的单目线索的数量。该研究将试图确定是否存在权衡使用立体与单眼编码技术使用心理旋转范式。图像将使用立体线索和各种单眼编码技术创建，包括隐藏线去除，阴影，纹理和旋转。图像中可用的单目线索的数量是不同的。这项实证研究将提供使用立体显示作为提供物体三维表示的工具所需的数据，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见解。

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.
