近来,随着个人显示器尺寸的稳步增加,影响眼球跟踪的几个技术问题已经出现。一个这样的问题是用作显示器边缘周围的参考点的近红外发光二极管的照明反射的损失。另一个问题是实际使用需要参考标识。因此,本文提出了视线估计与透明标记的大型显示环境,以解决这些问题。透明标记可以分布在屏幕上,并且使用线性偏振角将唯一ID分配给每个标记。使用偏振相机通过角膜上的反射来检测参考。使用50英寸显示器进行的实验结果表明,所提出的方法可以估计的注视点的误差在2.1度以内。我们证实,在相当大的显示屏上的标记可以有效地用作参考,而不是照明源。
Several technical issues that affect eye-tracking have arisen concomitantly with the steadily increasing sizes of personal displays recently. One such issue is the loss of the illumination reflection of the near-infrared light-emitting diodes used as reference points around the edge of the display. Another issue is that reference identification is required for practical usage. Therefore, this paper proposes gaze estimation with transparent markers for large display environments to solve these problems. The transparent markers can be distributed on the screen, and a unique ID is assigned to each marker using linear polarization angles. The reference is detected using a polarization camera through the reflection on the cornea. The results of experiments conducted using a 50-inch display indicate that the proposed method can estimate the point-of-gaze to within 2.1 degrees of error. We confirmed that on-screen markers in sizable displays could be effectively used as references instead of illumination sources.
