Anamorphosis for 2D displays can provide viewer centric perspective viewing, enabling 3D appearance, eye contact and engagement, by adapting dynamically in real time to a single moving viewer’s viewpoint, but at the cost of distorted viewing for other viewers. We present a method for constructing non-linear projections as a combination of anamorphic rendering of selective objects whilst reverting to normal perspective rendering of the rest of the scene. Our study defines a scene consisting of five characters, with one of these characters selectively rendered in anamorphic perspective. We conducted an evaluation experiment and demonstrate that the tracked viewer centric imagery for the selected character results in an improved gaze and engagement estimation. Critically, this is performed without sacrificing the other viewers’ viewing experience. In addition, we present findings on the perception of gaze direction for regularly viewed characters located off-center to the origin, where perceived gaze shifts from being aligned to misalignment increasingly as the distance between viewer and character increases. Finally, we discuss different viewpoints and the spatial relationship between objects.

用于2D显示器的变形可以通过实时动态适应单个移动的观看者的视点来提供以观看者为中心的透视图观看，从而实现3D外观，目光接触和互动，但以其他观看者的观看失真为代价。我们提出一种用于构造非线性投影的方法，该方法将选择性对象的变形渲染同时还原为场景其余部分的普通透视图渲染。我们的研究定义了一个由五个角色组成的场景，其中一个角色以变形角度选择性地渲染。我们进行了一项评估实验，并证明了针对所选角色的以观看者为中心的追踪图像可以改善凝视和参与度估计。至关重要的是，执行此操作不会牺牲其他观众的观看体验。另外，我们提出了关于从原点偏心放置的常规观看角色的注视方向感知的发现，随着观看者与角色之间距离的增加，感知的注视从对齐到错位越来越多。最后，我们讨论了不同的观点以及对象之间的空间关系。
