AquaCAVE是一种水下沉浸式投影环境，忠实地再现了虚拟空间中的游泳体验。AquaCAVE的灵感来自于被称为CAVE自动虚拟环境的周围投影系统，在该系统中，立体图像被投影到用户周围的表面，但解决了几个与水有关的问题，这些问题在以前的系统中没有研究。在本文中，我们描述了克服配置沉浸式投影系统的特定于水的问题的技术。水的三个主要特征是枕形变形、反射和红外(IR)辐射吸收。现有的基于红外或蓝光的运动捕获系统不适用于水下沉浸式投影环境，因为红外被吸收，并且蓝光干扰用户观看立体图像。因此，我们提出了一种适用于AquaCAVE的可见光头部跟踪装置。结果表明，所提出的基于圆极化的方法是有效的，能够实现持续清晰的视野、稳定的头部跟踪和反射减少。通过这种方法，我们可以构建出适用于未来水下娱乐和强化游泳训练的拟议的AquaCAVE。
AquaCAVE is an underwater immersive projection environment which faithfully reproduces the swimming experience in the virtual space. AquaCAVE is inspired by the surrounding projection system known as the CAVE Automatic Virtual Environment, where the stereoscopic images are projected to the surfaces surrounding the user, but addresses several water-specific problems that were not studied in previous systems. In this paper, we describe techniques to overcome the water-specific issues for configuring the immersive projection system. Three characteristics of water that mainly cause problems are pincushion distortion, reflection, and infrared (IR) radiation absorption. Existing motion capture systems based on IR or blue lights are not feasible for an underwater immersive projection environment since IR are absorbed, and blue lights disturb a user to see the stereo-scopic images. Therefore, we propose a setup for visible-light head tracking, which is functional for AquaCAVE. As a result, the proposed circular polarization-based method was shown to be valid to enable a constantly clear view, stable head tracking, and reflection reduction. With this methodology, we can build the proposed AquaCAVE that can be applicable to future underwater entertainment and enhanced swimming training.
