Abstract

In our research, we are interested in simulating realistic quadrupeds [2008]. Previous eye-tracking results have shown that faces are particularly salient for static images of animals and humans [2005; 2004]. To explore whether similar eye-movement patterns are found for dynamic scenes depicting animals, we displayed multiple 4-second (56 frame) grey-scale video clips of farm animals (goat, horse, sheep) walking and trotting. Using an EyelinkII eye-tracker, we recorded the eye-movements of 7 participants who were instructed to view the experiments with a view to subsequently answering questions about the movements. As it has been shown that human and animal motions activate different areas of the brain in children [2003], we also showed the participants the same number of videos showing humans walking and running. Figure 2 shows several frames of three of the video clips, with the eye-fixations of one participant overlaid. This depicts a very typical eye-movement pattern found in most of the videos, in that participants first looked at the head of the animal, then looked along the torso, finishing at the hips.
人与动物的眼球追踪动态场景
在我们的研究中,我们感兴趣的是模拟真实的四足动物[2008]。先前的眼动追踪结果表明,在动物和人类的静态图像中,人脸尤为突出[2005;2004]。为了探索是否在描绘动物的动态场景中发现类似的眼球运动模式,我们展示了多个4秒(56帧)的农场动物(山羊、马、绵羊)行走和小跑的灰度视频剪辑。使用EyelinkII眼动仪,我们记录了7名参与者的眼球运动,他们被指示观看实验,并随后回答有关运动的问题。由于已经证明人类和动物的运动激活了儿童大脑的不同区域[2003],我们还向参与者展示了相同数量的人类行走和跑步的视频。图2显示了三个视频片段的几个帧,其中一个参与者的眼睛注视重叠在一起。这描绘了一个在大多数视频中都能找到的非常典型的眼球运动模式,参与者首先看动物的头部,然后看躯干,最后看臀部。
