人类的扫视是一个动态的信息追求过程。有许多方法使用全局上下文或局部上下文线索来模拟人类扫视扫描路径。与它们相反，本文介绍了一种使用全局和局部线索的注视运动控制模型。为了测试该模型的性能，使用采样率为1250 Hz的SMI iVIEW X高速眼动仪采集人眼运动数据进行实验。该实验采用了二乘四的混合设计，其中包括目标位置和四个初始位置。我们将所提出的模型生成的扫视扫描路径与人脸基准数据集上的人眼运动数据进行比较。实验结果表明，该模型模拟的扫描路径在注视顺序、豪斯多夫距离以及静态注视位置和动态扫描路径的预测精度方面与人类扫视相似。
Human saccade is a dynamic process of information pursuit. There are many methods using either global context or local context cues to model human saccadic scan-paths. In contrast to them, this paper introduces a model for gaze movement control using both global and local cues. To test the performance of this model, an experiment is done to collect human eye movement data by using an SMI iVIEW X Hi-Speed eye tracker with a sampling rate of 1250 Hz. The experiment used a two-by-four mixed design with the location of the targets and the four initial positions. We compare the saccadic scan-paths generated by the proposed model against human eye movement data on a face benchmark dataset. Experimental results demonstrate that the simulated scan-paths by the proposed model are similar to human saccades in term of the fixation order, Hausdorff distance, and prediction accuracy for both static fixation locations and dynamic scan-paths.
