对于无玻璃混合现实(MR)，半空成像是将虚拟图像叠加到真实对象上的一种很有前途的方法。我们专注于将虚拟图像附加到非静态的现实生活对象上。在以前的工作中，移动真实对象会导致叠加系统的延迟，并且虚拟图像似乎跟随对象有延迟。这是由于传感器、显示器和用于位置检测的计算设备以及偶尔用于移动图像生成源的致动器造成的延迟造成的。为了避免这一问题，本文提出将目标锚定成像效应与位置感知分离。我们的建议是一种名为“天空锚”的逆向反射系统，它只由光学设备组成：两面镜子和一块航空成像板。该系统反射来自锚定在物理对象自身下方的光源的光，并形成锚定在对象周围的图像。这种光学解决方案原则上不会造成任何延迟，对于高质量的混合现实应用是有效的。我们考虑将两种类型的光源附着到物理物体上：从物体所在的触摸台反射内容，或者直接将光源附着在物体上。至于位置传感，我们利用物体底部的电容标记，在触摸台上进行跟踪。我们已经实现了一个原型，其中半空图像随着对象移动，其内容可能会根据对象的位置而变化。
For glass-free mixed reality (MR), mid-air imaging is a promising way of superimposing a virtual image onto a real object. We focus on attaching virtual images to non-static real life objects. In previous work, moving the real object causes latency in the superimposing system, and the virtual image seems to follow the object with a delay. This is caused by delays due to sensors, displays and computational devices for position sensing, and occasionally actuators for moving the image generation source. In order to avoid this problem, this paper proposes to separate the object-anchored imaging effect from the position sensing. Our proposal is a retro-reflective system called "SkyAnchor," which consists of only optical devices: two mirrors and an aerial-imaging plate. The system reflects light from a light source anchored under the physical object itself, and forms an image anchored around the object. This optical solution does not cause any latency in principle and is effective for high-quality mixed reality applications. We consider two types of light sources to be attached to physical objects: reflecting content from a touch table on which the object rests, or attaching the source directly on the object. As for position sensing, we utilize a capacitive marker on the bottom of the object, tracked on a touch table. We have implemented a prototype, where mid-air images move with the object, and whose content may change based on its position.
