摘要

光场显示允许观看者看到与视图相关的3D内容,就像透过窗户看一样;然而,现有的光场显示相互作用的研究工作是有限的。然而,它们有可能并行2D笔和触摸屏系统,为自然交互提供联合输入和显示表面。我们提出了一个使用双用途透镜阵列的四维显示和交互空间,它结合了光场显示和光场笔传感,并允许我们估计笔的三维位置和二维方向。该方法简单、快速(150Hz),距离透镜阵列0-350mm位置精度为2-3mm,精度为0.2-0.6mm,在45度视场范围内定位精度为2度,精度为0.2-0.3度。此外,我们3D打印了嵌入挡板的透镜阵列,以减少出界串扰,并使用光学继电器允许焦平面后的相互作用。我们展示了我们的联合显示/传感系统与交互光场绘画。

Joint 5D Pen Input for Light Field Displays
Light field displays allow viewers to see view-dependent 3D content as if looking through a window; however, existing work on light field display interaction is limited. Yet, they have the potential to parallel 2D pen and touch screen systems, which present a joint input and display surface for natural interaction. We propose a 4D display and interaction space using a dual-purpose lenslet array, which combines light field display and light field pen sensing, and allows us to estimate the 3D position and 2D orientation of the pen. This method is simple, fast (150Hz), with position accuracy of 2-3mm and precision of 0.2-0.6mm from 0-350mm away from the lenslet array, and orientation accuracy of 2 degrees and precision of 0.2-0.3 degrees within a 45 degree field of view. Further, we 3D print the lenslet array with embedded baffles to reduce out-of-bounds cross-talk, and use an optical relay to allow interaction behind the focal plane. We demonstrate our joint display/sensing system with interactive light field painting.
