This project developed a system that allows manipulation of complex displays in real time, contingent on the eye position of an observer. The goal of these experiments is to examine the nature of the representations that guide visual behavior during normal tasks, involving movements of the eyes and coordination of the eyes and hand. These experiments extend the analysis of visual operations to processes operating over a longer time scale than is usually considered, with an unprecented degree of stimulus control. This now allows the analysis of visual representations moment by moment. The other innovative aspect of the technique is that by measuring the consequences of the visual manipulation on task performance (e.g., by measuring fixation duration), we have a much more sensitive indicator of the experimental manipulation than is normally available. The experimental methodology has been developed over the last two years, and our results in the current grant period reveal that vision may be much more task-dependent than previously thought. Thus different fixations on the same visual stimulus serve a different purpose. The results also indicated that the visual information that is retained across successive fixations depends on moment-by-moment task demands and is used to minimize the amount of working memory. Recent Progress. The software for virtual displays of the Baufix parts has been installed. This was made available to us through our collaboration with Sagerer at the University of Bielefeld.

该项目开发了一个允许操纵的系统 实时显示复杂显示，取决于 观察者。 这些实验的目的是检查 指导正常任务中视觉行为的表示形式， 涉及眼睛的运动和眼睛和手的协调。 这些实验将视觉操作的分析扩展到 比通常更长的时间尺度运行的过程 考虑，具有无效的刺激控制程度。 现在 允许瞬间分析视觉表示。 这 该技术的其他创新方面是，通过测量 视觉操纵对任务执行的后果（例如 测量固定持续时间），我们有一个更敏感的指标 实验操作比通常可用的。 这 实验方法学是在过去两年中开发的， 我们在当前赠款期间的结果表明，愿景可能是 比以前想象的要依赖于任务。 因此不同 相同视觉刺激上的固定剂具有不同的目的。 这 结果还表明保留的视觉信息 跨连续的固定取决于一时的任务需求 并用于最大程度地减少工作记忆量。 最近的 进步。 Baufix零件虚拟显示的软件具有 已安装。 通过我们的 与Bielefeld大学的Sagerer合作。
