我们描述了旨在测量人类在面对面和显示介导条件下的注视方向感知能力的实验。注视感知能力是通过观察者的实际注视与参与者的判断之间的音调差异的绝对值来确定的。我们比较了面对面、立体图像和单视场图像条件下的能力。平均而言，参与者在面对面的情况下感知观看者的注视方向最准确。正如预期的那样，立体图像条件下的精度高于平面图像条件下获得的结果。然而，个别数据并没有遵循预期的顺序，我们的探索性实验表明，瞳孔间距比两个立体相机之间的距离更窄的参与者很难判断注视方向。我们还发现，注视方向的俯仰分量的感知受到注视传输方法的影响，但偏航分量是鲁棒的并且不受传输条件的影响。
We describe experiments designed to measure gaze direction perception capability of humans under face-to-face and display mediated conditions. Gaze perception capability was determined by means of the absolute values of the pitch differences between a looker's actual regards and participants' judgments. We compared the capability under face-to-face, stereoscopic image, and monoscopic image conditions. On average, participants perceived the looker's gaze direction most accurately under the face-to-face condition. As expected, the accuracy under the stereoscopic image condition was higher than the results obtained under the monoscopic image condition. However, individual data did not follow the expected order and our exploratory experiments showed that participants with narrower interpupillary distance than the distance between two stereo cameras had difficulty in judging gaze directions. We also found that the perception of the pitch component of gaze direction is affected by gaze transmission methods but the yaw component is robust and is not affected by the transmission conditions.
