在本文中，我们描述了增强现实中的虚拟对象的阴影表示的效果。光学一致性对于创建逼真的增强现实环境是重要的。我们专注于提供准确的阴影，并提出了两个假设的虚拟对象的阴影表示的效果。首先，虚拟对象的阴影提供了真实的世界与虚拟对象之间的更强的连接，并且因此增加了虚拟对象的存在。第二，虚拟物体的阴影提供了深度线索，从而使界面用户更容易获得三维感知。我们报告的两个实验表明，这些假设是正确的。我们还发现，用户报告说，一个特征的阴影形状提供了更多的虚拟对象的存在，尽管不正确的虚拟光的方向。
In this paper, we describe the effects of shadow representation of virtual objects in augmented reality. Optical consistency is important in order to create realistic augmented reality environments. We focus on providing accurate shadows and made two assumptions about the effects of shadow representation of virtual objects. First, that the shadow of virtual objects provides a stronger connection between the real world and virtual objects and so increases virtual object presence. Second, that the shadow of virtual objects provides depth cues and so makes three-dimensional perceptions easier for the users of the interface. We report on two experiments that show that these assumptions are correct. We also find that users report that a characteristic shadow shape provides more virtual object presence in spite of incorrect virtual light direction.
