关于逼真的虚拟化身的逼真度还有一些悬而未决的问题,这表明仍然有大量的发展需要完成,特别是虚拟世界在我们的教育,工作和娱乐中发挥着更重要的作用。使用看起来很像的化身可能会完全改变我们在虚拟世界中的互动方式。本文研究了其他人的长相相似的化身的特征影响我们的感知现实主义。四个层次的化身表示进行了评估,在这个试点研究:静态化身,一个静态的化身与唇同步对应的音频记录,全脸动画音频和全身动画。结果表明,全脸和身体动画是非常重要的,在增加化身的感知现实主义。更重要的是,参与者发现对口型动画比其他任何动画都更令人不安(恐怖谷效应)。这些结果对在协作虚拟环境中感知其他人的长相相似的化身有影响。
There are outstanding questions regarding the fidelity of realistic look-alike avatars that show that there is still substantial development to be done, especially as the virtual world plays a more vital role in our education, work and recreation. The use of look-alike avatars could completely change how we interact virtually. This paper investigates which features of other people’s look-alike avatars influence our perceived realism. Four levels of avatar representations were assessed in this pilot study: a static avatar, a static avatar with lip sync corresponding to an audio recording, full face animation with audio and a full body animation. Results show that full-face and body animations are very important in increasing the perceived realism of avatars. More importantly, participants found the lip sync animation more unsettling (uncanny valley effect) than any of the other animations. The results have implications for the perception of other people’s look-alike avatars in collaborative virtual environments.
