我们提出了一个 step-by 步指南的建设和使用的实验设置, 允许同时跟踪眼睛和 dichoptic 呈现视觉刺激。在许多情况下, dichoptic 刺激使用, 关键的问题, 防止有效的眼睛跟踪是 dichoptic 表示阻挡视线的视频眼追踪。这是通过使用红外线透明的镜子和红外线敏感的眼睛跟踪器来解决的。这种设置允许3D 视觉, 双眼抑制或临床研究的研究员收集高质量的眼球跟踪数据, 同时使用大的, 任意颜色的刺激。
<p c...

在正常的观察条件下, 我们的每一个眼睛都接受一个稍微不同的视觉输入。然后处理这个输入, 以产生一个连贯的, 三维的世界代表。Dichoptic 演示, 独立控制两只眼睛所呈现的输入的实践, 从而使研究人员能够从两个 two-dimensional 视网膜图像2中重建一个三维的表示.,3,4。另外, 如果两只眼睛的图像太不相同, 这种双眼组合就会失败, 而观察者却只报告其中一个图像的感知, 而另一只则被压制, 在诸如双目对抗等现象中5和连续的 flash 抑制6。这种双眼抑制的研究人员, 也使用 dichoptic 演示, 在这种情况下, 以检查与主题有关的问题, 如神经轨迹的意识7, 感性选择8,9, 和无意识正在处理10。
凝视和瞳孔动力学在人类行为和知觉的研究中被记录为多个目的。凝视方向可以通知有关, 例如, 注意分配11,10,13和决策14, 而瞳孔大小可以显示可视处理的各个方面15, 16, 任务约定17, 或流体智能18。
结合眼跟踪与 dichoptic 演示是有用的研究, 例如, 三维 (3D) 知觉19,20,21,22或视觉反应在双眼抑制期间输入23,24,25。例如, 在连续的 flash 抑制23中, 发现了眼球运动, 而没有主观感知的无意识处理。临床视觉研究人员可以使用的能力, 跟踪两眼在 dichoptic 的演示, 以调查眼部疾病, 影响两眼非对称, 例如, 监测单眼和双目视觉失真发生在弱视26和黄斑27。
我们最近描述了一个设置1 , 它允许高质量的视频眼跟踪和 dichoptic 刺激的组合, 对刺激的大小或颜色的限制很少, 我们评估了它的性能。下面我们将总结这个设置的构造和使用。

how to build a dichoptic presentation system that includes an eye tracker

不同的刺激对两只眼睛的介绍, dichoptic 介绍, 是必要的研究涉及3D 视觉和双眼抑制。关于瞳孔和动眼神经测量的独特实验价值的文献越来越多, 特别是对双眼抑制的研究。虽然获得眼球跟踪措施将有益于使用 dichoptic 演示的研究, 但 dichoptic 演示的硬件 (如镜子) 通常会干扰高质量的眼球跟踪, 尤其是在使用视频眼睛跟踪.我们最近描述了一个实验性的设置, 它将一个标准的 dichoptic 演示系统与红外眼睛跟踪器结合使用红外透明镜像1。安装程序与标准监视器和眼跟踪器兼容, 易于实施, 而且价格适中 (按1000美元的顺序)。相对于现有的方法, 它具有不需要特殊设备的好处, 对视觉刺激的性质和质量的限制很少。在这里, 我们提供了建设和使用我们的设置视觉指南。

在协议中描述的校准后, 我们执行了校准-验证程序, 而不存在镜像的问题。图 5清楚地说明了该方法的有效性, 它显示了照相机的图像 (使用研究端眼跟踪系统) 与镜像到位。两组平行线沿参与者的鼻子和眼睛眉毛以上的线是镜子的边缘, 但, 然而, 在该框架内的脸是一样清楚的, 因为它是外面。这突出显示了在相机记录的波长上缺少信号损耗。一个正式?...
