Our long-term goal is to produce experimental results and theoretical analyses that will yield insight into how visual information from the two eyes is integrated and how this information allows us to interact effectively with objects in our environment. Our short-term goal is to work on four topics, namely, visual direction, binocular eye movements, 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. This is not as simple a question to answer as one might expect, because we have two eyes. That is, an object in front of one eye is not in front of the other eye, and the question is how does the brain integrate the information from the two eyes to judge the directions of objects. Binocular Eye Movements. We will also continue to study how the two eyes move together. It has been known for some time that the eyes do not move independently, and we are examining how they move together in both the same direction (e.g., leftward) and in different directions (e.g., inward). Motion Parallax. We will also continue to study how movements of the head produce what is referred to as motion parallax and how this information contributes to our 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 begin a 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 retinae. 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.

我们的长期目标是产生实验结果和理论分析，从而深入了解两只眼睛的视觉信息是如何整合的，以及这些信息如何使我们能够与环境中的物体进行有效的互动。 我们的短期目标是研究四个主题，即视觉方向、双眼运动、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。 这个问题并不像人们想象的那么简单，因为我们有两只眼睛。 也就是说，一只眼睛前面的物体不在另一只眼睛前面，问题是大脑如何整合两只眼睛的信息来判断物体的方向。 双眼眼球运动。 我们还将继续研究两只眼睛是如何一起移动的。 一段时间以来，人们已经知道眼睛不会独立运动，我们正在研究它们如何在同一方向上一起运动（例如，方向）和不同方向（例如，向内）。 运动视差。 我们还将继续研究头部的运动如何产生所谓的运动视差，以及这些信息如何有助于我们对深度的感知。 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。 我们将开始一个新的研究项目，研究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。
