Our long-term goal is to produce experimental results and theoretical analyses that will yield insight into how visual and body movement information is integrated and how this information allows us to interact effectively in our environment. Our short-term goal is to work on three topics, namely, visual direction, motion parallax and visual stability. Visual Direction. We will continue to study how observers judge the directions of objects in the environment with respect to themselves. In order to judge direction correctly, information about eye position (or movement) with respect to the head, as well as about where the images form on the retinas, is required. The question is how does the brain integrate the two sets of information. Motion Parallax. We will also continue to study how movements of the head contribute to the perception of depth. Although early visual scientists were aware of the usefulness of motion parallax as a cue to depth, the details of what information the brain uses have yet to be worked out. Visual Stability. We will continue a relatively new research project on how the visual world remains stable when we move our head and eyes. With every movement of the eyes, images of stationary objects sweep across the retinas. Despite this, however, the world appears stable. To date this stability or constancy has been studied primarily under conditions in which the head is held stationary and only the eyes are free to move. The stimulus situation we wish to examine is an extension of this traditional one; namely, we wish to examine perceptual stability when both the head and the eyes are free to move. The research outlined is conceived of as basic research that will contribute to the development of a comprehensive theory of space perception and an understanding of how human sensory and motor mechanisms work together.

我们的长期目标是产生实验结果和理论分析，从而深入了解视觉和身体运动信息是如何整合的，以及这些信息如何使我们在环境中有效地互动。 我们的短期目标是研究三个主题，即视觉方向，运动视差和视觉稳定性。 视觉方向。我们将继续研究观察者如何判断环境中物体相对于自身的方向。 为了正确判断方向，需要关于眼睛相对于头部的位置（或运动）以及图像在视网膜上形成的位置的信息。问题是大脑如何整合这两组信息。运动视差。我们还将继续研究头部的运动如何有助于深度感知。 虽然早期的视觉科学家已经意识到运动视差作为深度线索的有用性，但大脑使用什么信息的细节还有待研究。目视稳定性。我们将继续一个相对较新的研究项目，即当我们移动头部和眼睛时，视觉世界如何保持稳定。随着眼睛的每一次运动，静止物体的图像扫过视网膜。尽管如此，世界似乎是稳定的。到目前为止，这种稳定性或恒定性主要是在头部保持静止，只有眼睛可以自由移动的条件下研究的。我们希望检验的刺激情境是这一传统情境的延伸;也就是说，我们希望检验头部和眼睛都能自由运动时的知觉稳定性。概述的研究被认为是基础研究，将有助于发展一个全面的空间感知理论，并了解人类的感觉和运动机制如何协同工作。
