角色动画需要像人体运动一样自然。为了实现该目标，存在一种方法，其中通过将注视行为添加到上下文情境并且将环境添加到一般行为动画，表达看起来像人类表达一样自然。然而，用户需要对一些注视控制参数的详细理解，以创建适合于使用注视控制器的情况的预期注视行为动画。并且对于初学者和几乎没有创建用户感觉足够的角色动画的经验的用户来说是困难的，因为需要试错调整。在本文中，我们提出了一种方法来创建一个角色的凝视行为动画的基础上观众的喜好，如“在哪里凝视”和“如何凝视”，而无需手动设置的凝视控制参数。我们将角色的凝视运动转换为凝视控制器的参数。并且，我们使用交互式遗传算法（伊加）获得优化的注视目标和控制参数的自然注视动画，观众觉得。在实验中，我们比较了手工创建和使用所提出的方法创建的方法和结果的印象。我们确认，用户可以创建凝视行为动画，具有手动创建的质量快速，方便地使用所提出的方法。
The character animation is required to appear as natural as human motion. Toward that goal, there is an approach where the expression appears as natural as the human expression by adding gaze behavior to the contextual situation and the environment to the general behavior animation. However, detailed understanding of some gaze control parameters is required for the users to create the intended gaze behavior animation that is suitable for the situation using the gaze controller. And it is difficult for beginners and the users that have little experience creating the character animation that the user feels to be adequate because trial-and-error adjustments are required. In this paper, we propose a method for creating a character gaze behavior animation based on viewer’s preference such as “where to gaze” and “how to gaze” without setting manually the gaze control parameters. We translate a character’s gaze motion into parameters for the gaze controller. And, we obtain the optimized gaze target and control parameters for the natural gaze animation that the viewer felt using the Interactive Genetic Algorithm (IGA). In experiment, we compare the impression of the method and result between the manual creation and the creation by the proposed method. We confirm that the user can create gaze behavior animation that has the quality of the manual creation quickly and easily using the proposed method.
