VIRTUAL FORCE STIMULATION

我们的主要重点是驾驶模拟器的开发， 虚拟显示器，带有眼睛和头部位置监控。 我们选择 驾驶作为一个测试范例，调查知觉和认知 在自然环境中发挥作用。 驾驶提供了一个良好的 环境研究短期认知信息处理，因为 关键的未经处理的信息会导致明显的行为结果 司机的错误。 它还允许调查自然行为， 这种情况仍然受到足够的限制， 严格的推论 注意缺陷与驾驶员的关系 错误已经得到了很好的证实。 这种赤字远比 与事故记录的相关性要比视觉缺陷更大 之一 传统范例的问题是安排“无人看管” 刺激，影响性能没有内隐注意转移。 这个问题几乎总是通过使用非常简短的方法来解决 演讲，这留下了一个开放的问题，即注意力是如何 在自然条件下部署。 在我们的驾驶模拟器中， 观察一个扩展的行为序列，同时保持严密的 实验对照 内隐注意力转移可以通过 操纵主要驾驶任务的需求。 最近 中求进工作总 这辆车安装在一个六自由度的运动 提供前庭输入的平台。

Our major focus is the development of a driving simulator using a virtual display, with eye and head position monitoring. We chose driving as a test paradigm to investigate perceptual and cognitive function in a natural environment. Driving provides a good environment to study short-term cognitive information processing since crucial unprocessed information leads to an obvious behavioral outcome in driver errors. It also allows investigation of natural behavior in a situation that is still constrained enough to draw theoretically rigorous inferences. The relation of attention deficits to driver errors has been well established. Such deficits are far more correlated with accident records than visual deficits. One of the problems with classical paradigms is arranging for `unattended' stimuli to influence performance without covert attention shifts. This problem is almost always approached by using very brief presentations, which leaves open the question of how attention is deployed under natural conditions. In our driving simulator we can observe an extended behavioral sequence while maintaining tight experimental control. Covert attention shifts can be controlled by manipulating the demands of the primary driving task. Recent Progress. The car was mounted on a six degree-of-freedom motion platform which provides vestibular input.
