摘要

研究表明,当在眼球运动和瞳孔大小变化中加入一些噪音时,关键帧眼运动被认为更真实。我们研究这种噪音,与运动捕捉相比,是否可以用标准技术合成,例如,程序或数据驱动的方法。在一个两种选择的强制选择任务中,我们比较了用四种不同的技术创建的眼睛动画:动作捕捉、程序、数据驱动和关键帧(缺乏噪声)。我们的知觉实验使用了三个具有不同真实感水平和两种动作的角色模型。我们的研究结果表明,程序和数据驱动的噪声可以用来创建动画,在类似的感知自然我们的动作捕捉方法。参与者在观看动画时的眼球运动表明,没有抖动的动画引起的注视更少,这表明人们很容易将其视为不自然的。

Perceptual Comparison of Procedural and Data-Driven Eye Motion Jitter
Research has shown that keyframed eye motions are perceived as more realistic when some noise is added to eyeball motions and to pupil size changes. We investigate whether this noise, in contrast to being motion captured, can be synthesized with standard techniques, e.g., procedural or data-driven approaches. In a two-alternative forced choice task, we compare eye animations created with four different techniques: motion captured, procedural, data-driven, and keyframed (lacking noise). Our perceptual experiment uses three character models with different levels of realism and two motions. Our results suggest that procedural and data-driven noise can be used to create animations at similar perceived naturalness to our motion captured approach. Participants’ eye movements when viewing the animations show that animations without jitter yielded fewer fixations, suggesting ease of dismissal as unnatural.
